Plastic waste, also known as plastic pollution, is defined as the buildup of plastic objects (such as plastic bottles and other items) in the Earth's ecosystem that has a negative impact on animals, wildlife habitat, and humans. Every year, the world produces more than 380 million tonnes of plastic. Only a quarter of it is recycled, while the other three quarters end up as contaminants in our natural surroundings and oceans. Plastics are regarded as one of the greatest innovations of the twentieth century. Because of their low cost and ease of usage, they are commonly used as packing and carry bags. However, due to the "Throw away culture'', plastics are increasingly considered an environmental hazard. This article will explain to you about plastic waste, which will be helpful in preparing the Environment syllabus for the UPSC Civil Service exam.

Plastic Waste - Types

Microplastics

• Microplastics are tiny plastic particles with a diameter of less than five millimeters.
• Microplastics include microbeads that are solid plastic particles with the greatest dimension of less than one millimeter.
• Microbeads are used in cosmetics and personal care products, and industrial scrubbers.
• Microfibers are also extensively used in textiles, and virgin resin pellets are used in plastic manufacturing processes.
• Apart from cosmetics and personal care goods, the majority of microplastics come from the breakdown of bigger pieces of plastic that were not recycled and disintegrated due to sun exposure or physical wear.

Single-use Plastics

• Single-use plastic is a throwaway material that can only be used once before being thrown away or recycled.
• They include plastic bags, water bottles, soda bottles, straws, plastic plates, cups, most food packaging, and coffee stirrers.
• At the Confederation of Indian Industry's Sustainability Summit in New Delhi, India pledged to eliminate single-use plastic by 2022.

Plastic Waste - Major Sources

Plastic Waste - India

• India produces about 26,000 tonnes of plastic daily, according to the Central Pollution Control Board (CPCB), and over 10,000 tonnes of plastic waste goes uncollected every day.
• According to a study conducted by the Federation of Indian Chambers of Commerce and Sector (FICCI), the plastics processing industry is expected to increase to 22 million tonnes (MT) per year by 2020, up from 13.4 MT in 2015, with single-use plastic accounting for over half of this.
• India's per capita plastic use is approximately a tenth of that of the United States of America, at less than 11 kg (109 kg).

Plastic Waste - Effects

On Aquatic Lives

• According to the United Nations, "at least 800 species worldwide are harmed by marine waste," with plastic accounting for up to 80% of the waste.
• Marine creatures can become entangled in plastic objects (such as the plastic rings that hold beverages cans together), consume the plastic, and/or be exposed to plastic toxins, all of which can cause physiologic changes over time.
• 'Sea turtles that consume just 14 bits of plastic have an increased chance of death,' according to new research.
• Young turtles are particularly vulnerable because they tend to drift with the same currents that attract plastic waste, and they are less choosy about what they consume than their elders.

On Human Health

• Polybrominated diphenyl ether (anti-androgen), bisphenol A (mimics the natural female hormone estrogen), and phthalates (also known as anti-androgens) are among the chemicals leached from plastics, and they have an impact on human health, causing hormonal and genetic abnormalities.
• These substances can disrupt the endocrine system and thyroid hormones, and they can be particularly harmful to women of reproductive age and young children.

On the Economy

• Tourism revenues are harmed by plastic waste near the shoreline (creates an aesthetic issue).
• The Andaman and Nicobar Islands, for example, are experiencing a plastic threat and an aesthetic issue as a result of worldwide plastic waste dumping on the islands.

On the Environment

• Land Pollution: Plastics leach dangerous chemicals onto land, destroying and lowering the quality of the earth's land surfaces in terms of use, landscape, and ability to support living forms.
• Air Pollution: When plastic is burned, harmful chemicals are released into the atmosphere, affecting human health and creating respiratory problems.
• Groundwater Pollution: When plastics are disposed of in landfills, the harmful chemicals are contained deep underground when it rains. Leaching chemicals and hazardous substances permeate aquifers and the water table, influencing groundwater quality indirectly.
• Water Pollution: Plastic waste floating on water surfaces has been found in a number of lakes and oceans, posing a serious threat to a variety of aquatic animals. It has terrible implications for aquatic animals that ingest the poisonous compounds.
• According to a United Nations research from 2014, the yearly cost of plastic pollution in the oceans is projected to be US$ 13 billion.
• Food Chain: Studies show that the pollutants interrupt the food chain by affecting the biology and reproduction processes, finally resulting in fewer offspring.
• When smaller species (planktons, mollusks, worms, fishes, insects, and amphibians) swallow plastic, they become intoxicated and transmit it on to larger animals, upsetting the food chain's interconnected linkages.
• Poor Drainage: Flooding is caused by a drainage system clogged with plastic bags, films, and other plastic materials.
• Impact on Habitats: Plastic waste sheets on the seafloor could function as a blanket, obstructing gas exchange and causing anoxia or hypoxia (low oxygen levels) in the aquatic system, which could harm marine life.
• Invasive Species: Plastic waste can provide transportation for species, potentially expanding the range of some marine animals or bringing species into previously uninhabited areas. This, in turn, has the potential to alter the region's environment.

Plastic Waste - Challenges

• Mismanaged Plastic Waste: When plastic enters the ecosystem via inland streams, wastewater outputs, and transport by wind or tides, it takes the form of microplastics/microbeads, which cannot all be filtered out once it reaches the ocean.
• Plastics have generated an island of waste called the Great Pacific Garbage Patch as they drift with ocean currents.
• Spurious Biodegradable Plastic: Untrue biodegradable and compostable plastics are entering the market because of a lack of rigorous testing and certification to validate claims made by manufacturers.
• Online or E-Commerce Companies: Apart from the plastic we consume through traditional retail, the popularity of online retail and meal delivery applications, which are now only available in major cities, is contributing to the surge in plastic trash.
• Microplastics: When microplastics reach the aquatic environment, they can float for long distances in seawater or settle on the seabed. Microplastics in the sky are trapped by clouds and falling snow, according to a recent study.
• Microplastic particles are often white or opaque in color, and many surface-feeding fish mistake them for food (plankton). They can even make their way up the food chain to human consumers (through contaminated fish/seafood/shellfish).
• Marine Litter: Plastic pollution in freshwater and marine habitats has been identified as a global issue, with 60-80 percent of marine plastic waste attributed to plastic pollution.
• Terrestrial Plastic: Land-based sources account for 80% of plastic pollution, with ocean-based sources accounting for the remaining 20%. (fishing nets, fishing ropes).
• Improper Implementation and Monitoring: In spite of the announcement of the Plastic Trash Management (PWM) Rules, 2016 and changes made in 2018, local bodies (even the largest municipal corporations) have failed to implement and monitor waste segregation.

Plastic Waste Management

• Reduce: The first step in reducing plastic waste is to support a tax on plastic bags, a ban on plastic manufacturing, and the adoption of plastic alternatives or biodegradable plastic.
• For example, the Khadi and Village Industries Commission's (KVIC) Project REPLAN (which stands for REducing PLastic in Nature) strives to limit the use of plastic bags by providing a more sustainable alternative.
• Reuse: Because reusing plastics reduces the need for new plastics, it can function as a natural restraint on plastic production.
• Recycle: The process of recycling waste or scrap plastic and turning it into usable items is known as plastic recycling. It has a number of advantages, including:
• Benefits to the economy as a result of value addition.
• Employment generation.
• Reduces the consumption of fossil fuels.
• Reduces the amount of waste in landfills
• Plastic recycling consumes less energy.
• Recovery: Recovery refers to the process of transforming non-recyclable polymers into a variety of industrially valuable energy and chemicals.
• Plastics can be used as a potential source of fuel because they contain mostly carbon and hydrogen and have a similar energy content to conventional fuels like diesel.

Plastic Waste - Government and Global Interventions

• On International Environment Day 2018, world leaders pledged to "Beat plastic pollution" by totally eliminating its use.
• The environment ministers of the Group of 20 (G20) have agreed to develop a new implementation framework for global initiatives to combat marine plastic waste.
• According to the Plastic Waste Management (Amendment) Rules, 2022, every local government must set up infrastructure for the segregation, collection, processing, and disposal of plastic waste.
• The Extended Producer Responsibility (EPR) idea was introduced by the Plastic Waste Management (Amendment) Rules 2018.
• A new national framework for plastic waste management is being developed, and third-party audits will be used as part of the monitoring process.

Private sector Participation in Recycling Plastic

• In India, certain companies have aided in the empowerment of the informal recycling sector, providing dignity and consistent revenue to waste pickers.
• Another company collaborated with the unorganized sector to develop high-quality recycled plastic.
• These businesses, large corporations, and governments might work together to develop novel ways to recover the value of discarded plastic while also investing in its phase-out.
• A Canadian company, for example, generates revenue from plastic waste in creative ways.
• It operates one of the largest waste plastic collection centres in the world, where rubbish can be exchanged for anything (from cash to medical insurance to cooking fuel).
• Multinational firms have invested in recycling infrastructure as well as a consistent and higher rate for waste plastic to encourage collection in low-income nations.
• Such collection centres, such as those run by India's informal aggregators, can be very low-cost investments (a storage facility with a weighing scale and a smart phone).

Plastic Waste - Mitigation

• Public Awareness: Raising public awareness of the dangers of plastic pollution through education and outreach activities in order to change behavior.
• Alternatives to Plastic: Single-use plastics, such as multi-layer wrapping, bread bags, food wrap, and protective packaging, would have to be prioritized in the fight against plastic waste.
• Economic Incentives: Before enacting the ban or levy, the government may provide economic incentives to stimulate the adoption of eco-friendly and fit-for-purpose alternatives that do not cause greater harm.
• Recycle And Reuse: Tax breaks, R&D grants, technology incubation, public-private partnerships, and funding for programs that recycle single-use items and turn waste into a resource that can be reused are all possible sources of assistance.
• Reduction/ Elimination of Import Dutires: Reduce or eliminate import duties on materials used to create alternatives.
• Tax Refunds: Introduce tax refunds or other criteria to help the alternative industry's move away from the plastic business.
• Use of Biodegradable/ Edible Plastics: Expanding the usage of biodegradable or even edible plastics made from ingredients like bagasse (the waste left over after sugarcane juice is extracted), corn starch, and grain flour.
• Baseline Evaluation: Conduct a baseline evaluation to identify the most problematic single-use plastics, as well as the existing causes, extent, and consequences of their mismanagement.
• Identification and Engagement of Key Stakeholders: To achieve widespread buy-in, identification and engagement of key stakeholder groups such as retailers, customers, industry representatives, local government, manufacturers, civil society, environmental groups, and tourism associations are necessary.
• Raising Funds And Financing: Use the funds raised by single-use plastics taxes or levies to maximize the public good, such as financing environmental projects or improving local recycling, and creating jobs in the plastic recycling sector through seed investment.
• Effective Implementation: Ensure that the plastic waste management measure is effectively implemented by ensuring that roles and responsibilities are clearly defined.
• Monitoring and Amendment: Monitor and amend the plastic waste management rules as needed, and keep the public informed about developments.

Conclusion

Given the country's economic position, consideration of the best ways to address the problem of plastic waste management (e.g., through regulatory, economic, awareness, and voluntary initiatives) is mandatory. Analyzing the degree of impact on the poor or what influence the desired course of action will have on different sectors and industries have been advised by experts to assess the potential social, economic, and environmental (positive and negative) impacts of the preferred short-listed plastic waste management measures/actions.

GS Mains Questions and Model Answers

Q1: Evaluate the impact of plastic waste on marine ecosystems and suggest measures to mitigate this issue.

Answer: Plastic waste significantly impacts marine ecosystems by introducing pollutants that are ingested by marine life, leading to health complications and mortality. Marine animals often mistake plastics for food, which can cause blockages in their digestive tracts and lead to starvation. Microplastics, which result from the breakdown of larger plastic items, accumulate in the ocean and enter the food chain, affecting the health of marine animals and humans who consume seafood. To mitigate this issue, measures such as banning single-use plastics, enhancing recycling programs, promoting biodegradable alternatives, and increasing public awareness are necessary. Governments and international bodies must collaborate to enforce regulations and support cleanup efforts to protect marine biodiversity.

Q2: Discuss the role of policies like Extended Producer Responsibility (EPR) in managing plastic waste.

Answer: Extended Producer Responsibility (EPR) plays a crucial role in managing plastic waste by holding manufacturers accountable for the lifecycle of their products. EPR policies require producers to manage the collection, recycling, and disposal of plastics, thereby incentivizing sustainable production practices. This approach helps reduce the burden on waste management systems and minimizes environmental impact. By ensuring that producers bear the cost of waste management, EPR encourages the design of eco-friendly products and supports a circular economy. Effective implementation of EPR policies, combined with public awareness and regulatory oversight, can lead to a significant reduction in plastic waste.

Q3: Analyze the challenges associated with recycling plastic waste and propose potential solutions.

Answer: Recycling plastic waste presents several challenges, including the sorting and contamination of different types of plastics, inadequate recycling infrastructure, and high processing costs. Many plastics are not recyclable due to additives or mixed materials, making the recycling process less efficient. To address these challenges, governments and industries must invest in advanced recycling technologies such as chemical recycling, which can handle complex plastic compositions. Public awareness campaigns promoting proper waste segregation at the source are essential to ensure clean recyclable waste. Policies incentivizing businesses to adopt sustainable practices and develop eco-friendly packaging can also contribute to the efficiency of recycling programs.
