Recycling Reality: Us Vs World Plastic Waste Management

Plastic recycling is a challenging and complex issue. Despite growing environmental awareness and legislative efforts to address plastic pollution, the recycling rates for plastic remain low globally, including in the United States. The economics of recycling are unfavourable, with virgin plastic being cheaper than recycled plastic due to fossil fuel subsidies. Sorting and processing plastic for recycling is expensive, and contamination from incorrect recycling further complicates the process, leading to additional costs. While some US states have successfully implemented bottle bills to encourage plastic bottle recycling, the overall recycling rate for plastics is still relatively small. With increasing plastic production and a lack of access to waste management and recycling facilities worldwide, the plastic waste crisis continues to worsen.

US recycling rate

The recycling of plastic in the US has been a concern for a while now. According to the US Environmental Protection Agency (EPA), the recycling rate of plastic in the US was 8.7% in 2018, with three million tons of plastic recycled. However, a report by The Last Beach Clean Up and Beyond Plastics revealed that the US plastics recycling rate fell to 5-6% in 2021. This is in contrast to the recycling rate of paper, which was at 66% in 2020.

The recycling rate of some specific types of plastic containers is more significant. For instance, the recycling rate of PET bottles and jars was 29.1% in 2018, while the rate for HDPE natural bottles was 29.3%. These types of plastic containers fall under the containers and packaging category, which had the most plastic tonnage at over 14.5 million tons in 2018. This category includes bags, sacks, wraps, other packaging, and bottles and jars.

The low recycling rate of plastic in the US is due to several factors. One factor is the economics of recycling. Virgin plastic, often subsidized by fossil fuel subsidies, is cheaper than recycled plastic. This price disparity discourages the use of recycled materials. Additionally, flexible packaging, such as lightweight packets for snacks and food, is difficult to recycle due to contamination and complex composition.

Another factor is the lack of infrastructure and education about plastic waste. While the US has implemented initiatives like the National Strategy to Prevent Plastic Pollution and the U.S. Plastics Pact, which aim to improve recycling and reduce plastic pollution, there is still a need for better infrastructure and communication to help Americans understand how to recycle plastic packaging.

The US Plastics Pact has set ambitious goals for 2025, including making 100% of plastic packaging reusable, recyclable, or compostable, and achieving a 50% recycling or composting rate for plastic packaging. These goals demonstrate the commitment to addressing the plastic waste issue in the US.

Barriers to recycling

Plastic is a complex material, with each type having unique properties that affect its colour, shape, structure, and melting point. This makes it crucial to sort plastic into different categories to keep it as pure as possible. However, this process of sorting and recycling plastic is complex and costly. It requires robust sorting systems and other processes like cleaning and melting the plastic, which consume energy. The economics of recycling are challenging, as virgin plastic, often subsidized by fossil fuel subsidies, is cheaper than recycled plastic. This discourages the use of recycled materials.

Another barrier to recycling plastic is the lack of knowledge and confusion among consumers about which plastics can be recycled and how the recycling process works. A survey found that 70% of respondents would recycle more plastic if they were better informed about what types of plastics could be recycled at home. This lack of education about plastic waste hinders a country's recycling efforts. Additionally, time pressures, especially for young families, are a barrier to improving plastic recycling rates.

The manufacturing process of products also presents challenges to recycling. Many products are designed in ways that make it difficult to separate and recycle the plastic content. Different plastic types may be combined, or other materials such as glue and metal may be bonded to the plastic, making it challenging to disassemble and recycle the product. This requires specific expertise and knowledge of materials during the design stage to ensure that products can be easily recycled.

Furthermore, not everyone has access to recycling facilities. Over 2 billion people worldwide lack access to essential waste management services, let alone recycling infrastructure. In some cases, even if recycling facilities exist, they may not accept all types of plastics, which again emphasizes the importance of sorting but also creates challenges for consumers in terms of knowing what can be recycled where.

Plastic waste management

To improve plastic waste management, governments and organizations worldwide are implementing new policies and frameworks. For instance, the Alliance to End Plastic Waste has developed the Plastic Waste Management Framework in collaboration with Roland Berger. This framework provides insights into policies and strategies that countries can adopt to enhance their waste management systems, increase recycling rates, and improve plastic circularity. It emphasizes the need for a circular economy, where plastic waste is reduced, recycled, or reused to minimize environmental leakage.

The United States Environmental Protection Agency (EPA) has also taken initiatives to address plastic pollution. The EPA released the "National Strategy to Prevent Plastic Pollution," focusing on eliminating plastic pollution in the environment. The EPA measures the generation, recycling, composting, combustion with energy recovery, and landfilling of plastic materials in municipal solid waste. In 2018, the recycling rate in the US was 8.7%, with 3 million tons of plastic recycled out of 35.7 million tons generated. While the overall recycling rate is relatively low, the recycling of specific plastic containers is more significant.

To improve plastic waste management and increase recycling rates, several steps can be taken:

• Improving waste management systems: Countries need to strengthen their waste management infrastructure and ensure proper collection and disposal of plastic waste. This includes providing access to recycling facilities and improving sorting and contamination control to increase the efficiency of the recycling process.
• Education and awareness: Educating the public about plastic waste management and recycling is crucial. Consumers play a vital role in enabling plastic recycling, and providing information about proper waste disposal, recycling techniques, and the negative impact of plastic pollution can empower individuals to make more sustainable choices.
• Addressing economic disparities: Virgin plastic, often subsidized by fossil fuels, is cheaper than recycled plastic, discouraging the use of recycled materials. By removing these subsidies and providing incentives for recycled content, governments can make recycled plastic more economically viable and attractive to manufacturers.
• Reducing plastic usage and promoting alternatives: Encouraging the use of reusable bags, containers, and products can help reduce the demand for single-use plastics. Additionally, supporting the development and use of biodegradable and environmentally friendly alternatives to plastic can decrease the overall plastic waste generated.

Plastic production

Asia is the largest producer of plastics in the world, with China alone accounting for 32% of global production in 2022. China produces between six and 12 million metric tons of plastic products each month. North America ranks second in terms of plastic production, with a 17% share in 2022. In the United States, plastic generation was 35.7 million tons in 2018, 12.2% of municipal solid waste (MSW) generation. The containers and packaging category had the most plastic tonnage, at over 14.5 million tons in 2018. This category includes bags, sacks, wraps, other packaging, bottles, and jars.

The economics of recycling plastic are challenging. Virgin plastic, often subsidised by fossil fuel subsidies, is cheaper than recycled plastic, discouraging the use of recycled materials. Additionally, flexible packaging, such as lightweight snack and food packets, is difficult to recycle due to contamination and complex composition. Addressing the global plastic crisis requires systemic change, including a fundamental shift in our relationship with plastic, driven by policy and innovation.

The total annual plastic production data from 1950 to 2015 was published by the Plastics Europe Market Research Group, with global annual fibre production data from 1970 to 2015 published by The Fiber Year and Tecnon OrbiChem. It is estimated that 8300 million metric tons of virgin plastics have been produced as of 2023.

Environmental impact

Plastic waste is a significant environmental concern, and recycling is one way to address this issue. However, the recycling rates for plastic are relatively low, with only around 9% of plastics ever recycled globally. The United States, in particular, faces challenges in plastic recycling due to economic factors and infrastructure limitations.

The environmental impact of plastic recycling is a complex issue. While recycling can help reduce plastic waste and conserve resources, it also has potential drawbacks. The process of recycling plastic requires energy and can result in the release of toxic chemicals, which can have negative consequences for human health and the environment. For instance, recycled plastics may contain higher levels of toxic chemicals, such as flame retardants, benzene, and carcinogens, which can harm human, animal, and environmental health. Therefore, it is crucial to carefully assess the potential risks and implement sustainable techniques to mitigate these impacts.

In the US, the recycling rate for plastic was 8.7% in 2018, according to the EPA. This rate is relatively low compared to the amount of plastic waste generated, which totaled 35.7 million tons in the same year. The low recycling rate can be attributed to various factors, including the economics of recycling and the lack of infrastructure in some regions. For example, virgin plastic, often subsidized by fossil fuel subsidies, is cheaper than recycled plastic, creating a price disparity that discourages the use of recycled materials. Additionally, flexible packaging, such as lightweight snack packets, is convenient but challenging to recycle due to contamination and complex composition.

Furthermore, the success of plastic recycling depends on consumers' actions and education. Consumers play a crucial role in enabling plastic recycling worldwide, but a lack of education about plastic waste hinders these efforts. According to a survey, only 51% of respondents received education about recycling in school. Additionally, not all plastics are accepted at recycling facilities, and contamination from incorrect sorting can spoil an entire batch of recycling. These factors highlight the importance of consumer awareness and proper sorting and cleaning of plastics before recycling.

To address the environmental impact of plastic waste, a systemic change is necessary. This includes reducing plastic production, finding sustainable alternatives, and implementing policies that promote recycling and reduce the use of toxic chemicals in plastics. By increasing the availability of recycled plastic, more businesses can incorporate it into their products, reducing their environmental footprint and offering consumers more sustainable choices. Additionally, a circular economy approach, which aims to eliminate waste by keeping resources in use for as long as possible, can help minimize pollution and build a more sustainable future.
