Plastics - Did we dig our own grave by inventing it?
‘Plastic’ is essentially the condensed
form of ‘thermoplastics,’ which describes polymers that can be moulded and
shaped upon application of heat. These long chains attribute plastics with critical
physical properties such as toughness, strength, and durability. Plastics are a
long chain of molecules typically derived from crude oil and natural gas.
Polyolefins (polyethylene and
polypropylene) are the most commonly produced synthetic polymers around the
world. Polyolefins are combined with several other materials while making multi-plastic,
and they are impossible to recycle. They can survive for centuries in our
environment and degrade painfully slowly. According to an estimate, about 5
trillion plastic bags are used every year in the world.
Plastics are ubiquitous as one can find
it in any place on our earth. It is no surprise that plastic waste has already
reached the deepest part of our ocean, Mariana trench as well the highest peak
of the world, Mt. Everest. Commonly sighted waste includes plastic bottles,
cups, packaging waste, plastic bags of various sizes, straws, lids, containers,
etc. and the list goes on. One cannot deny the fact the plastics became an
inherent part of our life given the benefits it provides us. It is unique as it’s
lightweight, durable, waterproof, affordable, and inert in nature, and thus, it
occupies a fixed place in our lives. Even those who sincerely avoid the use of
plastics are highly probable to encounter it in some other form.

Producers today are not accountable for
the plastic they use for the purpose of manufacturing and shipping. Shifting
the onus to consumers has failed miserably due to the ineffective waste
management systems and high complexity in handling. We need to change our
relationship with the plastics fundamentally. With ever-increasing population
growth, the need to reduce our dependency on plastics will become ever more important.
The future looks bleak with the way we are handling plastic waste today, and it
is important for each one of us to find a more viable and sustainable
alternative. Nations should improve their recycling methods, technology, and
infrastructure.
If we continue to stay indifferent to
our consumption patterns and handling of waste management, plastic waste in the environment will reach colossal numbers by 2050. The plastic industry will also
reach 20% of the total global fossil fuel consumption if the current production
trends continue.
In this blog, I try to present an
overview of the crisis that our world is currently facing today and scrutinize
the potential alternatives and further throw some light on how governments,
enterprises and consumers can make a difference in tackling this issue.
Plastic – Is it a miracle in our lives?
Plastic Industry has seen tepid growth
in the beginning years with its presence mainly in the manufacturing of daily
household items and some domestic products.
Production of plastics for the last 50
years has exceeded all the other materials, and most of it is intended for
discarding after using once. Packaging materials based out of plastics form the
most significant chunk, 50% of the total plastic waste generated in the world.
The plastic industry has contributed
significantly to India’s economic development and growth in various key sectors,
including Automotive, Construction, Electronics, Healthcare, and FMCG. The plastic
industry growth rate in India is the highest in the world, which is projected
to grow at 16% per annum.
EU, US, and Japan are the largest
plastic packing producers in the world, whereas Asia is the largest packaging
consumers. Currently, only 9% of the 9 billion tonnes of plastic that is
produced every year is recycled, and at this rate, it is estimated that 12
billion tons of plastic litter will end up in landfills, environment, and
plastic industry will account for around 20% of the oil consumption. According
to a study conducted by WWF, unless we do significant changes in the way we use
plastics and manage the waste, pollution will double by 2030.
Figure 1: Global plastic waste by disposal
Plastic Resin
Production:
The key raw material using which
plastics are produced is ethylene, which is a gas extracted from non-renewable
fossil fuels like crude oil or natural gas. Various chemicals, solvents, and
additives are further added to ethylene before subjecting to polymerization
that creates the long chain of molecules in the form of resin. The plastics
that we use in our daily lives are a by-product of re-extrusion of this resin
and further processing.
Today, most of the single used plastic
waste is disposed of in landfills as we do not have a strong eco-system to
collect and recycle this waste. Owing to its chemical properties, plastics are
highly stable, and thus, they remain almost eternal. In order to augment the
resistance of plastic films to acidic contents, manufacturers tend to add
antioxidants, thereby slowing the decomposition rate further.
Today, we speak of an industry which
employs lakhs of people in both direct as well as indirect jobs in our
country. According to an estimate by CRISIL, the domestic polymer demand is
projected to grow at a very strong pace for the next five years, with
polyethylene, polypropylene, and PVC as the key demand drivers.
Plastic &
the human bondage
Plastic plays a crucial role in food
packaging, ensuring arresting food losses, wastage, and contamination. Right
from the time food is harvested till it is consumed, plastic is the extensively
used increasing its shelf life, ensuring safety and protection from pests. The UN
Food and Agriculture Organization (FAO) underlines the importance of packaging
and storage to ensure food is distributed safely.
It has been proven that plastic
packaging tends to show a net positive impact on our environment when compared
to greenhouse gases, water, energy use, and food distributed without packaging.
Discarding packaging will have severe implications for our food security,
safety, and lead to severe food wastage. As per the Danish Environmental
Protection Agency, life cycle analysis study of several different alternatives
show that plastics have a lower environmental impact in comparison to others
highlighting the trade-off conundrum we face.
The evil side
of plastics
If we all think for a moment about this
crisis, it is astounding to realize that plastic waste is an inherent part of
our culture as we regard it as an expendable item than something as an invaluable resource that is capitalized to meet our needs.
The moment plastic waste becomes a part
of the environment, we are plagued by the multitude of issues it creates.
Plastic waste obstructs the water courses flowing by it and inhibits the vital
groundwater seepage. As most plastic waste is seen on sewers, ponds, lakes, and
canals in our cities, sewers, water flow is blocked, and thus they end up as
breeding areas for mosquitoes and can lead to spreading of dangerous diseases
like malaria. We are ingesting our bodies with microplastics through our food
chain and various carcinogenic chemicals used in making plastics can cause
irreversible damage to our organs.
Mismanaged plastic waste that is
discarded or dumped in open landfills, road-side litter that can eventually
enter our surroundings is significantly higher in low to middle-income
countries owing to immature waste management practices. Asia and African countries
contribute to 90% of this portion, whereas Europe and North America are very
advanced with a minimum contribution of 5%.
Plastics such as PVC can leach harmful
chemicals like additives and various compounds into the soil, water, and
landfills turning everything into toxic. On the other hand, incineration, which
is widely used in the EU region and the United States, though manages waste
effectively generates greenhouse gases and contribute to air pollution.
Plastics also contribute to the
so-called chemical burden on our environment. Plastics cause higher damage when
exposed to sunlight / burning them as the molecules break and release toxic
gases. According to data cited by the United States Environmental Protection
Agency, plastics alone contribute to 14% of the toxic gases which were released
in the air.
Toxic emissions like dioxins, carbon
monoxide mainly result from incomplete combustion of polyethylene, polystyrene,
polypropylene, and PVC. Hence, environmental control of emissions and strict
monitoring is essential to ensure that incinerators are efficient and release
waste gases as per prescribed standards.
Production of the plastic resins itself
causes severe irreversible damage to our environment though it is not visible
to our eyes. Polymerization and refining process employs sophisticated
techniques to increase efficiency but releases dangerous toxic gases like
benzene, ethylbenzene, nickel oxides, and other high-volume pollutants into our
atmosphere. Chemical additives which are used in the production also have
serious negative environmental and health effects on humans due to the release
of toxic substances like lead, cadmium, mercury, and other carcinogens.
Scenario in India
India generates a whopping 15,000
tonnes of plastic waste every day. Indians are notoriously famous for
mismanaging plastic waste in the form of open burning or throwing litter
everywhere without any sense. This is mainly due to inefficient waste
management systems, incompetent municipal bodies, and lack of awareness, and
thus, it is extremely challenging to collect and recycle the waste. Hence,
public and municipal bodies resort to open pit burning of plastic waste.
Plastic waste has been debated and discussed by several bodies, governments
over the past decade, but the progress is minimal.
India’s tallest rubbish mountain in Ghaziabad, Delhi is on course to grow taller than the iconic Taj Mahal by 2020. With 2000 tonnes of garbage dumped each day, it is projected to reach 73 meters soon.

Urban India is better in handling
plastic waste compared to rural India owing to effective collection and
segregation at source, adequate facilities, and better processing of the
collected waste. However, rural India suffers from many challenges and still
follows orthodox practices.
Today, we use multilayer plastics for
wrapping almost everything from potato chips to shampoos. It is ironical that
attention is not paid to the management and disposal of plastic waste though we
all see how much of it is floating in our oceans and clogging the rivers. Although
there is a huge backlash against plastic waste pollution by many Indian
NGO’s, very little has changed in the minds of the people of our country and
the governments.
India’s shift towards rapid urbanization,
smart cities development, increased sales of packaging products through various
channels, changing consumer preferences, and buying patterns are driving
plastic growth today. It is projected that plastic consumption in India will
touch 20 million metric tonnes per annum by 2020.
Plastic waste recycling in India
Recycling of plastic is a difficult task
in India as it faces tough challenges in collecting the waste, segregating,
transporting, processing, and then re-manufacturing. With high costs along this
process chain and low value for the recycled product, it is not so attractive
and hence needs government subsidies. To add to the woes, Indians lack
awareness and discipline when it comes to the disposal of plastic waste or
recycling. Both the government and industry must come forward and work together
to change the mindset of people and promote effective plastic waste management.
Figure 3: Plastic recycling clusters - India
Plastic recycling in India is primarily
done by several unorganized players spread across the country, supporting the lives
of thousands of families. The informal sector plays a key role in safeguarding
the plastic out of landfills. This sector is dependent on rag pickers who earn
very meagre wages for collecting the whole waste day and selling it to buyers
at their processing facilities.
PET bottles in India has a reasonable
recycling rate due to the strong informal network of scrap dealers in every
part of India. It is economical for putting efforts into collecting thick
polypropylene than in collecting thin polypropylene. Also, recyclable plastics
turn useless when they are soiled as the cost of recycling is further increases
due to initial washing. Recovering plastics is a civic one than a technological
problem.
Saving recyclable waste material from
going to disposal centers or landfills is crucial and should be our focus. Effective
recovering at the source of waste will save cost, efforts and can be profitably
used for recycling. Brand owners should come forward and share the
responsibility of managing plastic waste and recycling it. We can also adopt
best practices of some of the states of our country as well as developed
nations for better reuse and recycling of packaging materials.
It is already known that inappropriate
plastic disposal disturbs the soil microbial activity, prevents groundwater
recharging, and in some instances releases carcinomic chemicals in the
atmosphere. With stray cattle, pigs and dogs feeding on thrown away plastics
and food, their lives are also endangered.
Some of the recent developments which
took place in addressing the problem of plastic pollution are shown in this
timeline.
Figure 4: Timeline of events in India - plastic ban
Many of the initiatives taken by the Indian government could not yield good results owing to poor implementation. Though
these are in line with our country’s target to phase out single-use plastics by
2022, the bans are not implemented in entirety, and there were several
loopholes and structural issues. It is essential for a country like India to
drive movement against plastics rather than banning them. People are always
disinclined to switch to alternatives in place of cheap and convenient plastics
as its deeply embedded in our economy.
Any measure taken should be customized,
considering the socio-economic status of the people living there. The recent
plastic ban imposed in the state of Maharashtra has led to overnight closure of
several small manufacturing firms leading to loss of jobs. Few firms have
adapted themselves by switching to manufacturing those packaging materials
which were immune from the ban.
Many of the plastic manufacturing firms in India are small-scale based industries, and hence, the industry needs to be pushed systematically as they cannot afford to absorb any shocks from plastic bans. Things which were not planned for had already taken its toll, but it is still possible to control the damage caused by plastic. Banning plastic is not a feasible solution to this problem, given the extent to which society is dependent on it for ensuring food storage and safety.

Banning plastic is not a feasible solution to this problem, given the extent to which society is dependent on it for ensuring food storage and safety.
India has already taken the right steps
in targeting single-use plastic items like cups, straws, coverts as they are
the most noticeable and omnipresent. However, the availability of alternatives
to plastics at an affordable price is the biggest hurdle we face today.
E-Commerce & problem with packaging
products
Packaging materials are the largest
market for plastics around the globe, and the trash generated after usage
accounts for at least half of the plastic waste generated worldwide.
The e-commerce industry, which is
growing at a swift pace in India is now a day one of the significant
contributors to the packaging waste. E-commerce packaging employs plastic,
bubble wraps, air packets, tape to safeguard the product. With changing buying
patterns and preferences, consumers want products to be delivered at their
doorstep. Products are handled several times from the moment it dispatched from
the warehouse, and thus, the packaging is optimized and customized for products.
Companies are adapting themselves to
the digital world and switching to online selling along with their traditional
outlets. Last year, China singles day online sales have generated a whopping
1.6 lakh tonnes of packing waste. Lack of laws governing the e-commerce packing
or usage of plastics has led to widespread exploitation of plastic waste in the
name of safe and efficient packing. Regulators framing laws for e-commerce
packaging is the need of the hour given the sheer size of the market and its
potential to take over brick and mortar stores. Online shopping is convenient
and makes our life more comfortable and has tremendous business potential.
However, this greediness for convenience should not blind us to the damage we
are causing to our environment.
We have already seen the product life
cycle of packaging material and how it is contributing to waste. E-commerce
companies should voluntarily come forward and take initiatives to promote green
packaging and other alternatives. This is entirely about the mindset of the
people involved in the supply chain, and it is time we proactively respond to
this driving the change. A holistic approach is needed to tackle the packaging riddle.
Today’s companies are adopting omnichannel distribution, which integrates both
online as well as in-stores to give the right consumer experience.
E-commerce giant Amazon has taken few
steps already to spread awareness and necessary actions to optimize the
packaging design. Their frustration free packaging criteria, which are a part
of their packaging certification program, has eliminated the usage of millions
of corrugated boxes. This program is designed to educate the industry on the
benefits of sustainable packaging to reduce the impact on our environment and
minimize costs throughout the supply chain.
Similarly, Dell has responded to the complaints
from customers about excessive packaging and non-recyclable shipping boxes long
back. They have reduced the size of boxes and started using bamboo cushioning
in place of foam and plastics, packaging material made from wheat straw,
etc.
Today, the retail marketplace is
continuously evolving, and companies need to consider the life cycle approach
during the design of the product as well as packaging. By working closely
together, they can meet the requirements of both online, offline retailers,
customer choices, and follow regulatory guidelines.
Some of the actions to reduce
e-commerce waste:
R1: Reduce - Manufacturers, e-tailers
and consumers must find ways to decrease the amount of packaging and filler
material used
R2: Reuse - Consumers can reuse
packaging for outgoing shipments including returns and repurpose packaging in
creative ways
R3: Recycling - Manufacturers should
continue to focus on creating packaging using recyclable materials
R4: Responsible disposal – All stakeholders must follow this.
Marine debris
Marine debris majorly consists of
plastic waste and microplastics accumulated over a period collected from
various sources. Ocean currents act upon them, leading to garbage patches which
can span thousands of square miles resembling floating islands. The Great
Pacific Garbage Patch is the largest of all marine debris formed in the north
Pacific Ocean contains majorly discarded ropes, fishing nets, and other plastic
mass, which accounts for nearly 52% of the total waste lying there.
Today, trillions of plastic waste pieces
are floating in the oceans already, and if plastic pollution is not abated,
virtually every seabird on Earth will end up eating plastic in some form. Commonly
found beach litter includes bottles, caps, food wrappers, used polythene bags,
polystyrene containers, disposed of plastic packaging.
Many habitats, ecosystems, and biodiversity
are getting lost due to marine litter present today. It costs all nations $8
billion per year in the form of costs for fisheries, aquaculture, marine
tourism, clean-ups. Even economic activity is impacted by marine litter in the
form of shipping, fishing, aquaculture, tourism, and recreation. Commonly
sighted marine litter is cigarette butts, plastic bags, fishing gear, food, and
beverage containers.
Microplastics
The name ‘Microplastics’ has been given
to the plastic particles which measure less than 5 mm in their dimensions on
any side. Industries manufacture primary microplastics in the form of
microbeads, fibres, capsules and resin pellets which are used to make
cosmetics, toothpaste, abrasives, etc upon subjected to heating. However, humanity
has indirectly led to the cause of another variety called secondary
microplastics that are formed by the fragmentation of large plastic waste.
These larger plastic pieces when exposed to UV rays from the sun and the
prevailing environmental conditions of rivers and oceans they disintegrate into
secondary microplastics. Owing to their smaller size, it is difficult to
monitor or track and thus easily gets ingested by various life forms, including
humans and can have a detrimental effect on the functioning of our bodies.
Microplastics have crossed all the
borders and are found in water bottles, fish and salt. Plastic waste present in
any form on water or land can be mechanically abraded by wave and wind action
creating microplastics that can be ingested by several marine life forms and
animals eventually ending in our food chain.
Many sea birds have already eaten plastic
and are feeding plastic scraps to their offspring unknowingly. Recently, a dead sperm whale was found washed up in
Spain in 2018, and upon opening its stomach, 32 Kgs of plastic bags and waste was
found. Microplastics were found in the deepest trenches of our oceans and high
up the tallest peaks of our planet.
Many studies conducted on this show
that table salt, tap water, and even bottled water have shown traces of
microplastics. At this point, we have limited information on its effects on our
health, but before this can cause serious damage to our organs, cells we need
to attack the root cause.
Our water bodies are shipping waste
into oceans
It is astonishing to see the trash that
we generate ends up in an uninhabited, remote place like Henderson island lying
in the Pacific Ocean, 3000 miles from human settlements. In a research study
conducted there, it is observed that more than 600 pieces of plastic are found
in every square meter of the island.
Indiscriminate dumping of plastic waste
in rivers and canals has contributed to today’s sad state of affairs. Direct
dumping of plastic waste is it any form contributes mostly to the litter we see
in rivers clogging it all the time. It is not surprising to find that rains
cause the mishandled waste we throw on land to enter local canals, sewers which
feed into larger tributaries, rivers and in turn empty into seas, oceans.
Polluted rivers, canals bring in a
significant portion of the plastic waste and feed our oceans. Top 20 polluting
rivers in the world account for more than 67% of the marine pollution when they
eventually enter the oceans. Also, these top 20 rivers are geographically
located in the Asia region. China’s
Yangtze River is the world’s most polluted river which empties vast amount of
plastic waste into the Pacific Ocean (through the East China Sea) brought in by
its surrounding tributaries spread across a vast land.
FIgure 5: Plastic waste release into oceans through rivers. (Source: Nature communications)
Ocean currents and tides transport this
disregarded plastic waste around the world circulating in huge gyres. Plastic waste often gets caught in these
gyres whirling and cycling in vast swaths and spreading across the ocean. These
currents carrying plastic have taken its toll on remote islands in the oceans
harming ecosystems and birds nesting there. Henderson Island has become the primary
settling site for the circulating trash in the oceans.
A look into the Global recycling industry:
Figure 6: Challenges of recycling. (Source: https://www.nationalgeographic.com/environment/planetorplastic/)
Nations like the US face complex
challenges in recycling plastic, mainly the post-consumed plastics like food
containers, packaging. As it is a complete labour-intensive process, it does not
make economic sense for recyclers. The harsh reality is that plastics collected
in recycling bins do not end up recycled and are sent abroad for processing.
Figure 7: Major exporters and importers of plastic
For decades, many of the western
countries have offloaded their plastic waste. China has been taking in the
plastic waste from several developed nations to help its manufacturing sector.
China has roughly imported around 100 million tons of plastic scrap during the
period 1992-2015. However, China's
plastic waste ban has wholly opened the eyes of our nations to find that we are
surrounded by a huge trash and recycling problem and the ugly world of the global
recycling industry has come into the limelight.
China in 2018 has ratified the
‘National Sword’ Policy, which prohibits 24 categories of recyclable waste,
including scrap plastic and paper into its country. This has created ripples
across many nations and has given thrust to the debate regarding domestic
recycling and reducing plastic consumption.
Figure 8: Export of plastic from various nations to Asian countries
It has also forced the US, Canada, and
EU nations to find an urgent alternative. Some of these countries have realized
the long-term effects and started implementing bans while others have moved to
other Asian nations accepting waste. EU has approved a bill to ban single-use plastics
which also transforms the responsibility to producers for clean-up of the mess.
Similarly, many US states are considering a comprehensive single-use plastic
ban, levying taxes and fees, banning polystyrene, etc.
South East Asian countries have
virtually become the world’s largest importer of non-recyclable plastic waste
in the backdrop of China’s chance of policies.
In 2018, Malaysia alone imported around
2.5 lakh tonnes of plastic scrap from the United States according to the data
sourced from Resource Recycling. Malaysia which has become the hub of all
non-recyclable plastic waste dumping has recently shut the illegal facilities
sending back the waste to the countries of origin giving a strong message to
all nations that it is not a dumping ground. The Philippines too acted in
similar lines sending back dozens of garbage containers shipped illegally.
Considering the current situation where
waste being dumped in several Asian nations illegally, environmental
organization Global Alliance for Incinerator Alternatives (GAIA) has given specific
recommendations for building a roadmap for sustainable transboundary movement
of plastic waste, measures to phase out single-use plastics, global
implementation of Extended Producer Responsibility (EPR).
It is imperative that every country
should develop and scale up their domestic recycling facilities and stop
exporting plastic waste to other nations. Exporting our waste to other
countries is not a sensible move in economic as well as sustainability terms. We
are losing more than 95% of the value of plastic waste in exports which can be
harnessed to recreate reusable plastics. We must keep aside our personal choices,
political prejudices, business interests, and come forward to find a practical
solution to this.
Solutions to handle the crisis
The current waste management systems
have not proven to be effective in controlling the damage being caused to our
environment, and thus, we need a build a holistic strategy to tackle this
problem. The problem of plastic pollution cannot be limited by just improving
our recycling methods and processes but by also focusing on creating environmentally
friendly and sustainable materials, studying newer models of plastic
consumption that will transform how we manufacture, circulate and use them.
Manufacturers, governments, and people
need to act decisively in manufacturing, managing, and using the plastics. In
order to address this century’s biggest burden on our environment, governments
need to act first and come up with stricter regulations; companies need to
innovate and focus on bio-based plastics; individuals need to reduce the usage
of plastics and support recycling.
Alternatives
It is essential to understand that there
can never be a single standard solution for reducing single-use plastics.
Involvement of all the stakeholders is necessary along with incentives from the
government to build strong public support. It can be learned from the success
stories from many countries in the EU and China that outright bans are
inefficient, and people have responded better to charging taxes, money for
using plastic bags.
Small adjustments to our family’s daily
routine can allow us to push our limits and make a real difference in the fight
against this plastic. Something as simple as avoiding plastic wrapping or
covers for items bought from stores and bringing our reusable bag can inspire
our fellow citizens and drive this fight against plastic.
Trade-offs are always present with the
substitutes that can be used in place of plastics, and it is challenging to
find balance in the available choices. For example, a reusable cotton bag
requires higher energy, and when compared to a plastic bag. Plastics are the
best solution to prevent food from rotting and preserving it for more extended
periods, and alternatives may not give desired results.
Few of the alternatives to plastics are
compostable coffee cups, personal care products made from wood, bamboo straws,
paper cards, metal drinking bottles, metal food containers, sustainable
clothing using natural fabrics, edible spoons, palm leaf plates. Some of the
naturally occurring organic materials that biodegrade rapidly are jute, silk,
wood, kenaf, cotton, flax, linen, wool, bamboo.
Our actions will
have the highest impact, and we need to educate and convince our friends,
family to refuse disposable plastics. Together we can fight plastic waste and
find a better way to use it sustainably.
Bioplastics
As single-use plastic and styrofoam
take at least 500 years to decompose in natural environments, Bioplastics are
a promising alternative. They are made from corn starch, sugarcane, and cassava
roots. With increasing attention in green plastic products, shift towards
healthy lifestyles and concern towards our environment, many consumers are
moving to bioplastics.
However, the market for these products
have not yet matured owing to higher costs, lack of availability, and
infrastructure to manufacture. Persistent efforts towards increasing awareness,
R&D, and developing environmentally friendly products by governments as
well industry will transform this industry and take over plastics.
Biopolymers made from biomass such as Polylactic
acid (PLA), Polyhydroxyalkanoates (PHA) polyesters produced by numerous
microorganisms and Thermoplastic Starch (TPS) are also a promising alternative
to the disposable plastics, packaging materials, and several other single-use
plastics. These alternatives will not serve the purpose unless we have a good
number of composting facilities. Many companies are turning greener and become
carbon neutral today. This will increase industrial composting facilities,
efficient management of waste practices and can be a perfect use case for
implementing at a large scale with acceptance from all stakeholders.
The widespread availability of Starch
has sparked interest in its strong potential to replace conventional plastics.
Thermoplastic starch is tried in packaging to protect goods in transit to study
its feasibility to replace polystyrene. After exploring such alternatives, it
is essential that we have to analyse the supply side constraints as in the name
of sustainable alternative plastics, we end up damaging our environment using
more water, fertilizers, biocides, and energy.
We might be bombarded with issues when
crops are deliberately grown to produce polymers based on biomass as this can
impact the soil availability for agriculture. Similarly, subsidizing crop
production as a raw material for biofuels or polymers to biomass base has
little sense in environmental terms if excessive water, fertilizers, pesticides
are used. The farming community will benefit from subsidy measures, but the
overall costs of environmental degradation are much higher.
The conundrum of
Bioplastics
The catch with the term ‘Biodegradable’
is that they do not degrade automatically in the natural environment, especially
not in our oceans. This often misleads consumers as the polymers degrade when
they are composted but in an industrial setting where temperatures are
maintained about 60°C for several weeks.
Bioplastics or biodegradable plastics are
currently produced at a very low rate in India. Even though they break down
faster than conventional plastics, it does not necessitate quick degradation. These
bioplastics also need separate waste management and compost facilities, which is
not present in many cities in our country owing to the additional installation costs.
So far, the name ‘bioplastics’ has been used for successful product marketing
with the context that consumers are not aware entirely of the facts.
The United Nations Environment
Programme (UNEP) to has cleared the misconceptions and impacts of biodegradable
plastics that they do not bring any change in the plastics entering our oceans.
This clear distinction should be informed to consumers so that sorting and
disposal is correctly done without mixing with conventional plastics.
In order to avoid confusion, bio-based
plastic products can be designed to allow consumers to distinguish more easily.
Some successful use-cases:
Loop™
- We need to go back to basics and reinvent the way we use products. A promising example in this regard is the way how revolutionary a zero-waste e-commerce system called Loop™ works. The Loop Alliance was launched at the recently concluded World Economic Forum meeting in Davos where it intends to drive zero waste packaging to answer the problems of plastic pollution.
Figure 9: Loop concept
(Source: https://www.weforum.org/our-impact/the-loop-alliance-plans-to-eliminate-plastic-waste-and-save-the-planet-you-can-too)
(Source: https://www.weforum.org/our-impact/the-loop-alliance-plans-to-eliminate-plastic-waste-and-save-the-planet-you-can-too)
- A pilot is being tried out in New York, where the olden day milkman is reinvented so that consumers can eat, drink, and wash without generating any plastic waste. Consumers order all the groceries (everything from juice to cereals, shampoo to detergent) which is delivered in glass and metal containers by the delivery person from the loop. Once the stock is over, empty cans are collected from the bag and taken back for washing and refilling at the delivery centers.
- It can be seen here in this concept that the accountability for packaging’s afterlife is shifted to a company from the consumers as a promising alternative to recycling. Loop alliance is a partnership by the world’s biggest consumer goods companies including P&G, Coca-Cola, Unilever, Carrefour, Tesco, Mondelēz, PepsiCo, Danone, Mars, Nestlé.
Kudumbashree
- One successful case study by the state of Kerala is the concept of Kudumbashree. This initiative is already playing a pivotal role in managing plastic waste in Kerala. In cooperation with the local bodies, Kudumbashree workers are entrusted with several tasks including a collection of plastic waste, biodegradable waste from households and operating shredding units where the output is routed for recycling. It is noteworthy that the waste collected from households against a fee aiming for generating zero waste from households. Recycled plastic is given to the local bodies for laying roads after mixing with bitumen and manufacturing other green products.
Other notable mentions:
- Plastic waste needs to be fought as a movement by the people of this country. One very inspiring real-life example is that of the environmentalist Afroz Shah, who has led a movement which has transformed the Versova beach in Mumbai. Known to be the world’s most substantial citizen-led beach clean-up, volunteers spearheaded by Mr. Shah have collected around 16.5 tonnes of plastic waste since 2016.
- Volvo cars have recently announced that from 2025, at least 25% of the plastics used in their new models will be used from recycled materials. They have also committed to remove single-use plastics from their offices, restaurants, and events by 2019 and replace them with sustainable alternatives.
- Swachh Bharat Abhiyan, one of the key Government initiatives have been able to change the mindset of people, and it has set the right platform for safe disposal of waste and worship cleanliness.
- To tackle the issue of growing plastic waste every year in India, a team at IIT Madras has developed a solar-powered mobile unit that converts the recyclable plastic waste into fuel oil that is cheaper than diesel. This equipment can generate up to 700 ml of oil for every KG of plastic used, and the oil can find its usage in off-highway applications. The sludge formed in this pyrolysis process is compressed and converted into light charcoal briquettes which are fed into the unit for running.
- Plastic is often seen as a worthless material considering its omnipresence nature. Consumers must sense the value of plastics and encourage reuse, recycling of it. Enterprises can promote the circular economy by introducing systems of deposit, return of some plastic products directly like PET bottles. A successful example in this regard is the introduction of Swachh Bharat Recycle Machine introduced by Indian Railways on a pilot basis at few stations in Mumbai. Consumers are also rewarded with a cashback into their PayTM account for dropping bottles. This coupled with extended producers’ responsibility, will stimulate the recycling. Germany and Japan are some of the very few countries who have succeeded in establishing the responsibility for recycling used plastic bottles by the manufacturers.
- A Thailand supermarket has come up with a unique way to replace packaging plastic for vegetables and food. They started to wrap it in banana leaves instead.
- Today, scientists and researchers are working extensively to find a way to solve the problem of plastic waste lying for years. One recent breakthrough is the invention of a bacterium by two young researchers that transforms plastic into carbon dioxide and water. Through this technology, they intend to clean the beaches as well as manufacture raw materials for clothing purpose.
How can Individuals make a difference:
Individuals have the power to wield more
than consumers by refusing single-use plastics and change their buying habits
in supermarkets. With such a positive move, retailers will not be able to
ignore these changing trends and push the suppliers for the best alternatives.
Consumers have to be the change drivers and make informed decisions and develop
sustainable consumption habits.
Our willingness is our biggest strength,
and each of us can change the way we use plastics and eliminate them. Not only
by saying ‘No to Single-Use Plastics’ but also by imbibing it culturally, we
will able be able to ask for reducing plastic waste, recycle more and put
pressure on the manufacturers to design innovative products which do not harm nature.
Some of the things that we can do in
our homes are:
- Sort waste at our sources for easy recycling
- Avoiding overpackaged products for consumption
- Wherever possible, employ reusable containers for storing food, drinks
- Reduce plastic footprint at our homes
- Check for recyclable products before buying
- Proactively learn about plastic alternatives
- Educating our friends, family about the crisis and possible solutions
- Refuse disposable plastics and single serving packaging
- Use reusable or degradable shopping bags
- Pressurize our local municipalities to put in deposit schemes
- Find innovative ways to replace single-use plastic in our everyday life
As informed consumers can promote
sustainable products, they play a decisive role but need the support of governments,
producers as well as retailers so that plastic products are labelled as per
standards. Societal pressure will push manufacturers to come up with new things
and ultimately can lead to the reduction of plastics. By continuously
monitoring and communicating the same, trust and commitment can be built among
the public for a greater good.
Upcycling also called as creative reuse is possible for many plastic goods following the end of their primary life. By encouraging this, a new second life can be given to plastics and adopt reusable reduce the demand for new resources and will provide an alternative to their plastic equivalents.

How can Governments make a difference:
Through strong policies from governments, a circular economy can be realized, and plastic waste can be reduced. Measures can be taken by the government with different timelines.
With the widespread outcry over plastic
pollution, governments have taken insignificant measures to wash off their
hands and prevent harm to them from the public. Plastic bans by several state
governments are one of them which was not implemented thoughtfully as people
tend to revert to their original practices.
Measures by government can be divided
into short, medium and long term as below:
Short term measures:
Ø Improve waste collection, sorting and reprocessing centers
Ø Building robust infrastructure to handle waste generated daily
Ø Formalizing the informal network of waste recyclers
Ø Create awareness among the public by using social media and promoting through iconic persons
Ø Put in place deposit schemes
Medium term measures:
Ø Focus on incentives to shift consumer purchasing habits
Ø Push retailers and manufacturers to move towards plastic alternatives
Ø Inject more money in R&D
Ø Standards to identify labels correctly and ensuring the same
Ø Tax on plastic bags usage
Ø Create viable markets for recycled plastics
Ø Establish clear regulatory frameworks for biodegradable plastics
Long term measures:
Ø Encouraging entrepreneurship and innovation
Ø Voluntary agreements with companies and
Ø Spare enough time to small scale industries to shift to alternatives from plastics production
Ø Implementation of extended producers’ responsibility nationwide
Ø Establish nationwide plastics protocol
Ø Scale up the adoption of reusable plastic packaging
Governments around the world are spreading awareness about the magnitude of the crisis. As single-use plastics, polythene bags and other polystyrene products are the most visible of the pollution caused by plastics, they have been the focus of government action.
Few of the initiatives that the government can take are:
Assess the social costs of any plastic ban introduced and evaluate how the poor are affected and how different sectors, industries are impacted
- Targeting single-use plastics at both source and consumption
- Determine the right approach in introducing alternatives by considering the socio-economic status of various states and regions.
- Coordinate with all stakeholders in the society including retailers, consumers, industry, environmental groups for taking their inputs
- Sensitize public about the damage caused by disposable plastics and the costs associated with it.
- Provide economic incentives in the form of tax cuts, R&D support, partnerships, support for projects, etc. to encourage adoption of alternatives
- Abolish import duty and taxes on materials used to manufacture plastic alternatives
- Provide incentives to the industry as well to embrace the shift to sustainable alternatives production
- Divert the revenue generated through taxes on plastic usage for public welfare or supporting green projects or building infrastructure for recycling
- Monitor the improvements and communicate to the public about the progress
- Make plastic alternatives promotion as a part of CSR activity and reward companies who actively endorse their responsibility towards plastics elimination
How can Enterprises make difference:
Many
experts opine that the problem of plastic is genuinely a problem of design. Our
world economies must change with regards to the systems, manufacturing,
distribution, and consumption of plastic as plastic is designed to be thrown
immediately after use. The private sector must innovate and adopt new models
reflecting their responsibility towards the impact caused by their downstream
products. Recycling of plastic as we all know is today compromised on every
front as the products are not adequately designed. As more and more chemical
products are added to plastic polymers, recycling gets complicated and
expensive.
The abundance
of plastic can give a false impression that the damage is done to the society,
living creatures, and the environment is minor. UN Environment has led the research
on the promising plastic alternatives to inform and inspire budding
entrepreneurs, companies, start-ups who are willing to innovate. They have
categorized the alternatives into three categories: Natural polymers, Synthetic
biopolymers to biomass base, which are compostable and Non-plastic materials
which are durable and reusable.
On the other side of the coin, all
companies must once again use design thinking to design and develop products
making them easier to recycle. They also should take ownership of the plastic
packaging and are to be held accountable for any ramifications of their
products on our environment.
As a part of public awareness, it
should be made obligatory for all businesses to mention clearly about the type
of packaging material, life, and other special composting needs to decompose
it. Through this, consumers will get clear information and can base their
decisions regarding purchase.
Conclusion:
Our present situation is dire, but there
is a solution to this problem. By changing our behavior and forming a movement,
we can reverse the trend of plastic waste and preserve our oceans, species, and
ecosystems. There is no universal solution to this crisis. We all must work
together to reduce our dependency on plastics that are inflicting enormous damage
to the environment
Combating the pollution caused by
plastic worldwide, every stakeholder needs to act responsibly. Manufacturers need
to redesign the products, packaging, and the delivery mechanisms which
prohibits usage of single-use plastic products. They should also take the onus
and bear the financial costs in managing post-use waste. Governments should
mandate EPR, enforce the ban of single-use plastics usage and usage of toxic
additives in manufacturing. The recycling ecosystem needs to be developed, and
waste pickers, handlers, recycling industry workers should be respected and
promoted. Open litter burning should be banned strictly as well as monitoring
of waste incinerators should be carried out by the government agencies.
The situation today is compelling
enough for each one of us to reassess the plastic usage, packaging, and the disposal that did not garner enough attention.
Our vision for the future of plastics
should inspire us to turn this waste into an economic opportunity. Making all
plastic recyclable can create lakhs of jobs, and entrepreneurs should be
encouraged. It is the right moment for countries to seize this opportunity and
promote a clean economy.
It is an undeniable fact that recycling
and reuse of plastic materials will primarily foster innovation and sustainable
practices. We all are cognizant of the fact that it is neither conceivable nor
prudent enough to remove plastics from the society given our dependency on
them. With plastic pollution and waste looming in our society, the use of
alternative materials will be the immediate way forward to correct the
situation.
Our world has witnessed an explosion of
plastic production in the past few decades due to its convenience and
inexpensive nature. Nation-wide prohibition of single-use plastics and plastic-based
materials though has the potential to reduce the amount of waste being dumped
into our environment must be executed systematically. By offering incentives to
consumers in order to boost the usage of biodegradable bags and other nature-friendly
single-use plastic alternatives, businesses can also benefit and utilize this
opportunity to fill the void.
So far, the mediocre Government
regulations have not led to complete behavioral change and single-use plastics
continue to be used in many places in India. A reliable waste management system
helps in preventing leakage of any plastic waste into our environment that is
generated from households, restaurants, companies. Governments must spearhead
the change initiatives and focus on building infrastructure and waste
management systems, promoting sustainable alternatives, collaborating with
industries, investing in R&D, and develop laws without any loopholes.
A complete shift to usage of sustainable
alternatives of plastics will take some time as the ecosystem needs to be
developed. However, as a short-term measure, the focus should be on reinforcing
waste collection and management systems, strengthening circular systems to bring
down the scale of plastic waste pollution.
