India's 30% recycling rate
The world produces about 400 million tons of plastic waste per year, with global plastic waste generation more than doubling from 2000 to 2019. Despite this, only 9% of plastic waste is recycled globally, with the bulk of it ending up in landfills or incinerated.
India's plastic recycling rate stood at 8% in 2019, with the country generating nearly 26,000 tonnes of plastic waste every day, second only to the United States and the European Union. In an effort to improve this situation, a consortium of Indian and Australian research organizations has developed a roadmap for India's circular economy for plastics, with a goal of recycling 67% of plastic waste by 2035. This roadmap includes strategies such as supportive infrastructure, effective recycling, consistent compliance, sustainable consumption, awareness and readiness, design for circularity, and commercial viability.
To achieve these goals, the consortium has set intermediate targets. By 2025, recycling capacity should reach 35.2 million tonnes, with plastics recycling and sorting infrastructure in place. Landfilled plastics should be reduced by 30%, and single-use plastics should be phased out. By 2030, recycling capacity should grow to 18.8 million tonnes, and the digitalization of the flow chain of polymers should be mandatory.
The roadmap is the result of collaborative research and engagement with industry, government, and community stakeholders. It aims to support the Government of India and industry associations in responding to the upcoming requirements of the United Nations Global Plastics Treaty. India's efforts to build a circular economy for plastics are expected to reduce plastic waste, drive innovation, and create new industries and jobs in a zero-plastic waste economy.

Plastic waste in the US
Plastic waste is a significant issue in the US, with the country being one of the world's largest consumers of plastics. Plastic use in the US has more than tripled since the 1980s, and it is estimated that the country consumed 18% of global plastic products in 2019. This high consumption has severe environmental consequences, as plastic waste pollutes land, oceans, air, and even food and human blood.
The US Environmental Protection Agency (EPA) measures the generation, recycling, composting, combustion with energy recovery, and landfilling of plastic materials in municipal solid waste (MSW). In 2018, plastics generation was 35.7 million tons in the US, a significant increase from 0.4% of total MSW in 1960. The recycling rate of plastic containers, such as PET bottles and jars, was 29.1% in 2018, while the rate for HDPE natural bottles was slightly higher at 29.3%. However, overall, only about 5% to 6% of plastics are recycled each year in the US, indicating a pressing need for improvement.
The EPA has recognized the severity of plastic pollution and has released the "National Strategy to Prevent Plastic Pollution," aiming to eliminate plastic pollution release into the environment. With plastic demand projected to increase, collaborative efforts between governments, industries, community organizations, and consumers are crucial to address this pressing environmental issue.

Global plastic waste
The recycling rate for post-consumer plastic was a mere 5% to 6% in 2021, according to a report by Last Beach Cleanup and Beyond Plastics. This rate is influenced by factors such as low recycling rates, population growth, consumer preference for single-use plastics, and low disposal fees in certain areas. The COVID-19 pandemic also played a role in the decline in recycling rates, as plastic pollution increased during that time.
The vast majority of recycling involves grinding, melting, and reforming plastic, a process that requires proper sorting and cleaning of materials, which can be costly and time-consuming. Mechanical recycling also has limitations, as many types of plastic can only be recycled once without developing defects and contaminants. Additionally, the market for recycled plastics is limited by the cheaper prime material, which undercuts the price of post-consumer plastic resin.
To address the global plastic waste crisis, there is a growing movement to reduce plastic production and promote circular economy practices. Consumers, brands, and governments are increasingly aware of the need to curb plastic pollution and are advocating for more effective waste management strategies. Efforts to ban hard-to-recycle plastics and implement deposit return schemes for plastic bottles are gaining traction. Additionally, new universal plastic regulations are being negotiated as part of a global plastics treaty, aiming to streamline the production, use, and reuse of plastic. While these initiatives provide hope, the immense profits and political power of plastic producers present significant challenges in the transition to a sustainable future.

Plastic waste in oceans
The world produces about 400 million tons of plastic waste a year, with global plastic waste generation more than doubling from 2000 to 2019 to 353 million tons. However, only 9% of plastic waste is recycled, with 15% collected for recycling but 40% of that disposed of as residues. The rest is incinerated, ends up in landfills, or evades waste management systems, ending up in uncontrolled dumpsites, or burned in open pits. This mismanagement of plastic waste leads to plastic pollution in the environment, including oceans.
Plastic pollution in the ocean, or marine plastic pollution, is a significant issue. It accounts for 80% of marine debris, with plastic particles ranging from large items like bottles and bags to microplastics formed from fragmented plastic material. Microplastics are a huge part of the problem as they can mimic fish eggs and are consumed by marine life. Once in the ocean, they are challenging and costly to filter out, becoming a permanent feature of the ecosystem.
The sources of plastic entering the ocean are diverse, with land and ocean-based sources contributing. Land-based sources include discarded plastic bags, cigarette butts, food wrappers, beverage bottles, straws, cups, plates, bottle caps, and single-use bags. These items are often improperly disposed of or not recycled, eventually finding their way into the ocean. Ocean-based sources include abandoned and lost fishing gear and nets, primarily made of plastic, which can entangle and harm marine life.
The consequences of plastic waste in the ocean are severe and widespread. Plastic pollution impacts most marine and terrestrial habitats, including the deep sea, Great Lakes, coral reefs, beaches, rivers, and estuaries. It poses dangers to wildlife and fisheries through entanglement, ingestion, and suffocation. As plastic does not fully biodegrade in water, it accumulates in the ocean, leading to the formation of garbage patches in gyre regions. These garbage patches are a visible manifestation of the ocean plastic problem.
Addressing the issue of plastic waste in oceans requires a multifaceted approach. It involves reducing plastic production and consumption, improving product and packaging design for reduced plastic use and better recyclability, and enhancing waste management and recycling technologies. International cooperation and policies are crucial, along with the involvement of governments, industries, scientists, non-governmental organizations, and consumers. Initiatives such as bans and taxes on single-use plastics are a step in the right direction, but more comprehensive measures are needed to curb plastic pollution in the oceans effectively.

Plastic recycling challenges
Plastic recycling is a challenging process, and despite good intentions, much of the plastic put into recycling bins is not actually recycled. The world produces about 400 million tons of plastic waste a year, but only a small percentage is recycled. In 2019, the global production of plastics from recycled materials was 29.1 million tons, which is only 6% of the total plastic production.
One of the main challenges of plastic recycling is the complexity of the material. Plastic is a collective name for several hundred different kinds of materials, each with unique properties that affect its colour, shape, structure, and melting point. This makes it crucial to sort plastic into different categories to maintain its purity. However, different types of plastic are often combined in manufacturing processes, making recycling more difficult. Additionally, many products are designed with plastic content that is difficult to separate and recycle, such as glue and metal screws bonded to the plastic.
Another challenge is the lack of a well-functioning market for recycled plastics. Recycled plastics are still viewed as substitutes for virgin plastic, and virgin raw materials are sometimes cheaper. To address this, it is essential to create separate markets for recycled plastics and increase their use among manufacturers. This can be achieved by setting recycled content targets and investing in improved recycling technologies to make secondary markets more competitive and profitable.
Furthermore, plastic recycling faces challenges due to economic and social behaviour issues. Recycling plastic is more costly and energy-intensive than creating plastic from raw materials, and it is expensive to collect and sort. International cooperation is needed to reduce plastic production and develop environmentally friendly alternatives, as well as to improve waste management and increase recycling.
Lastly, the build-up of plastic waste in the environment is a significant concern. A major portion of plastic produced annually is used for disposable packaging or short-lived products discarded within a year. As a result, substantial amounts of end-of-life plastics accumulate as debris in landfills and natural habitats worldwide. While recycling is an important strategy for managing this waste, it is not keeping pace with the increasing plastic production, and more drastic changes are needed to address this growing crisis.
