The Reality Of Plastic Recycling: Annual Recycling Rates

Plastic is a cheap and versatile material used in a wide range of applications, from construction to food packaging. However, it has become an environmental concern due to its persistence in the natural world and the challenges associated with its disposal. While the world produces around 350-400 million tonnes of plastic waste annually, only a small fraction of this is recycled. The recycling rate varies across countries, with the US recycling 8.7% of its plastic waste in 2018, India recycling 30% of its 3.4 million tonnes of annual plastic waste, and the global average being 9%. This low rate of recycling means that most plastic waste ends up in landfills, is incinerated, or leaks into the environment, causing pollution.

India's 30% plastic recycling rate

The world produces about 400 million tons of plastic waste a year, with only 9% of it being recycled. Global production of plastics from recycled materials has more than quadrupled from 6.8 million tonnes in 2000 to 29.1 million tonnes in 2019, but this is still only 6% of the size of total plastics production.

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 rate, a consortium of Indian and Australian research organisations has developed a roadmap for India's circular economy for plastics, with a goal of recycling 67% of plastic waste by 2035.

The roadmap includes seven types of policy: supportive infrastructure, effective recycling, consistent compliance, sustainable consumption, awareness and readiness, design for circularity, and commercial viability. It also emphasizes the need for collaboration between the government, industry, and research institutions to achieve these targets.

By 2025, India aims to have plastics recycling and sorting infrastructure in place, with a recycling capacity of 35.2 million tonnes. Single-use plastics are expected to be phased out, and landfilled plastics reduced by 30%. The roadmap is designed to support the Government of India in implementing the United Nations Global Plastics Treaty, which is set to come into force in 2024.

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. The use of plastics in the US has more than tripled since the 1980s, and it is a major contributor to the growing global plastic waste crisis. In 2019, US plastic waste generation was estimated at 73 million metric tons, which corresponds to more than 220 kilograms per person. This is roughly five times the global average per capita.

The US has struggled to keep up with the increasing plastic waste due to a lack of recycling infrastructure. Despite a rise in paper recycling rates, plastic recycling rates have mostly stagnated or decreased over the years. In 2018, the US recycled 8.7% of its plastic waste, and this number decreased to an estimated 5-6% in 2021, according to a report by Beyond Plastics and The Last Beach Cleanup. This means that of the 40 million tons of plastic waste generated in the US in 2021, only about 2 million tons were recycled, while the rest ended up in landfills or was incinerated.

The low recycling rates in the US can be attributed to a variety of factors. Firstly, there is a "decades-long misinformation campaign to perpetuate the myth that plastic is recyclable," according to Judith Enck, the president of Beyond Plastics. Consumers are confused about which types of plastics can be recycled, as most municipalities only recycle certain types, such as PET and HDPE. Additionally, waste management experts say that plastic is expensive to collect and sort, and with thousands of different types of plastic that cannot be melted down together, it becomes challenging to recycle.

The US has also historically relied on exporting large volumes of plastic waste to other countries, particularly China, for recycling. However, China restricted foreign waste imports in 2018, leading the US to turn to other Asian countries, which have now also restricted foreign waste imports. This has further strained the US recycling system, as municipalities scramble to find new domestic markets and retool facilities to handle contaminated recycling loads.

To address the plastic waste crisis, environmentalists and lawmakers in some states are pushing for legislation banning single-use plastics and encouraging refill and reuse systems. Despite resistance from the plastic and oil industry lobbyists, successful recycling rates have been achieved in some states, such as Oregon and Michigan, through "bottle bills" that pay customers to return their plastic bottles.

Plastic waste in the ocean

The world produces about 400 million tons of plastic waste a year, with some estimates placing the figure at 350 million tons and others at 450 million tons. However, the recycling rate of plastic waste is extremely low, estimated at 9% globally, with some sources suggesting an even lower rate. This means that a significant amount of plastic waste is not being recycled, incinerated, or disposed of in controlled landfills. As a result, it ends up polluting the environment, with an estimated 1 to 2 million tons of plastic entering our oceans each year.

The presence of plastic waste in the ocean has severe consequences for marine wildlife and ecosystems. It affects marine life through ingestion, entanglement, and the release of toxic chemicals. Plastic waste does not biodegrade but instead breaks down into smaller pieces known as microplastics, which can be ingested by marine organisms, leading to health issues and even death. These microplastics can also enter the food chain, potentially impacting human health.

To address the issue of plastic waste in the ocean, several measures need to be implemented. Firstly, there is a need for international cooperation to reduce plastic production and promote environmentally friendly alternatives. This includes encouraging the development and use of biodegradable plastics and improving product design to minimize plastic waste. Additionally, efforts to improve waste management and increase recycling rates are crucial. Implementing taxes on single-use plastics, landfill taxes, and deposit-refund systems can provide incentives for recycling and reduce the amount of plastic waste entering the ocean.

Furthermore, addressing the issue of mismanaged plastic waste is essential, especially in poorer countries, where most of the ocean plastics originate. This involves improving waste collection systems, ensuring proper disposal, and providing education and infrastructure to support recycling and waste management. By taking a comprehensive approach that targets plastic production, consumption, and waste management, we can make significant strides in reducing plastic waste in the ocean and mitigating its impact on marine life and ecosystems.

Plastic recycling rate in the US

Plastic recycling rates in the US have historically been low, with a rate of 8.7% in 2018, 5-6% in 2021, and a peak of 9.5% in 2014. This is in contrast to the recycling rates of other materials, such as paper, which had a recycling rate of 68.2% in 2018. While the US produced 7.4 million tons of plastic waste in 1980, this figure increased fivefold to 35.7 million tons in 2018, and 40 million tons in 2021. This increase in plastic waste generation, coupled with low recycling rates, has led to concerns about plastic pollution in the environment.

The low plastic recycling rates in the US can be attributed to various factors. One significant issue is the contamination of recyclable plastics with non-recyclable plastics. When residents mix different types of plastics, the loads become contaminated and are often sent to landfills or incinerated instead of being recycled. Additionally, there is a "decades-long misinformation campaign to perpetuate the myth that plastic is recyclable," according to Judith Enck, the president of Beyond Plastics. The three-arrow recycling symbol, for example, can be misleading, as most municipalities only recycle certain types of plastics.

However, efforts are being made to improve plastic recycling rates in the US. The US Plastics Pact, for example, has set ambitious targets for its Activator members, including a goal to make 100% of plastic packaging reusable, recyclable, or compostable by 2025. They also aim to recycle or compost 50% of plastic packaging and achieve an average of 30% recycled content in plastic packaging by the same year. These targets demonstrate a commitment to reducing plastic waste and improving recycling infrastructure in the US.

Furthermore, the US Environmental Protection Agency (EPA) has released the "National Strategy to Prevent Plastic Pollution," which aims to eliminate plastic pollution in the environment. The strategy focuses on reducing the use of non-recyclable plastic packaging and promoting the use of packaging that is more easily captured and recycled. The EPA also encourages the use of post-consumer recycled content in plastic packaging and the development of innovative reuse models. These initiatives highlight the growing recognition of the importance of addressing plastic waste and improving recycling rates in the US.

Plastic recycling in developing countries

The world produces about 400 million tons of plastic waste each year, with only 9% successfully recycled. The remaining plastic waste ends up in landfills, is incinerated, or leaks into the environment, especially in poorer countries. This is due to the lack of proper waste collection systems and the economic incentives to recycle.

Developing countries face significant challenges in dealing with plastic waste due to limited resources and infrastructure. While some plastic waste is purchased and repurposed, the majority of it still ends up in the environment, contributing to pollution and environmental degradation. Wealthy nations have historically transported their plastic waste to poorer countries, shifting the environmental burden to these less developed regions. However, this practice has led to the emergence of a potential economic bright side to this trade for developing countries.

Improving waste collection systems is crucial for developing countries to address broader waste management issues. By partnering with local municipalities, businesses can ensure that their products are collected and responsibly managed at the end of their life cycle. This can also create opportunities for local reuse, recycling, and recovery economies. Additionally, developing countries can explore alternative product designs or materials, such as bio-benign materials like paper, glass, or biodegradable plastics, to reduce the environmental impact of their waste.

Bans on single-use plastics and landfill taxes can also play a role in reducing plastic waste in developing countries. However, these measures must be carefully considered, especially in the context of food and water security, as they may have unintended economic and social consequences. Ultimately, the solution to the plastic waste crisis in developing countries lies in a combination of improved waste management, increased recycling, and the development of environmentally friendly alternatives.
