Recycling Efforts: Us Vs Global Plastic Waste Management

Plastic pollution is a pressing global issue, with plastic production ramping up and an ever-smaller percentage being recycled. In the US, the recycling rate for plastic waste was only 5% in 2021, with almost 95% of plastic ending up in landfills, oceans, or the atmosphere. This is a decrease from the US's peak recycling rate of 9.5% in 2014. Globally, the picture is similarly bleak, with plastic use and waste projected to nearly triple by 2060. The crisis is driven by the low cost and high profitability of plastic production, with plastic manufacturers having immense political power. However, some states are pushing for legislation banning single-use plastics and encouraging reuse and refill systems.

Plastic production is ramping up, but recycling rates are low

Plastic production is increasing, but recycling rates remain low, with serious consequences for the environment. According to Greenpeace, the plastic crisis is worsening, and without drastic changes, it will continue to deteriorate as the industry plans to triple plastic production by 2050.

In the United States, the recycling rate for plastic waste is extremely low. While the official recycling rate was 8.7% in 2018, it has since declined, with studies showing that only about 5% of plastic waste was recycled in 2021. This means that the vast majority of plastic ends up in landfills, the ocean, or scattered in the atmosphere as toxic particles. The problem is not unique to the US; globally, plastic use and waste are projected to nearly triple by 2060, while recycling rates are expected to increase only marginally.

The low recycling rates are attributed to several factors. Firstly, plastic is challenging and costly to collect, sort, and reprocess. There are thousands of different types of plastic, and they cannot be melted down together. Plastic also degrades quickly and becomes more toxic with reuse. Additionally, the recycling infrastructure faces capacity issues, especially after China stopped accepting plastic waste in 2018 due to its low quality.

To address the plastic pollution crisis, systemic changes are necessary. Experts emphasize the need for drastic cuts in plastic production, particularly single-use plastics. There is a growing push for legislation banning single-use plastics and promoting reusable and refillable alternatives. The development of better, more recyclable products and sustainable alternatives is also crucial. While some states have successfully implemented "bottle bills" that incentivize customers to return plastic bottles, industry lobbyists often resist such initiatives.

The United Nations is working towards a global treaty to end plastic pollution, with an agreement expected by 2024. This treaty aims to set the course for future generations by promoting reuse and refill systems or eliminating packaging altogether.

Plastic is cheap to make and profitable, but expensive to recycle

Plastic is a rapidly growing segment of municipal solid waste (MSW). In 2018, the United States generated 35.7 million tons of plastic waste, with containers and packaging accounting for over 14.5 million tons. While recycling plastic is challenging and expensive, producing new plastic is cheap and easy. This discrepancy has led to a growing crisis, with an increasing amount of plastic waste and a relatively small amount of recycling.

The recycling process for plastic involves two main challenges: generating a pure stream of recycled material and ensuring sufficient residual value. Sorting and separating recyclable materials is labor-intensive and costly due to the wide variety of plastic types and additives used in products. Additionally, different kinds of plastic cannot be combined in manufacturing, further complicating the recycling process.

The cost of recycling plastic varies depending on the location and the price of oil. In certain areas, such as Los Angeles and San Francisco, recycling can provide an economic benefit over dumping. However, the overall cost of recycling a bottle compared to producing a new one can differ. The functionality of recycled plastic is also a concern, with some questioning whether consumers would accept products made from recycled plastic.

Despite these challenges, some states have successfully implemented "bottle bills" that incentivize customers to return their plastic bottles for recycling. These initiatives have faced resistance from the plastic and oil industry lobbyists. Additionally, the EPA has released the "National Strategy to Prevent Plastic Pollution," which aims to eliminate plastic pollution in the environment.

While recycling efforts are important, environmentalists advocate for a shift towards systems of reuse and refill to address the plastic pollution crisis effectively. This includes encouraging the use of alternative materials and products that reduce the demand for single-use plastics. By combining recycling initiatives with a focus on reducing plastic consumption, we can work towards a more sustainable future.

Plastic is not widely accepted at recycling plants

Additionally, there are thousands of different types of plastic, each with its own resin code, and they cannot be melted down together. The variety of plastic types has led to challenges in sorting and recycling processes, and some plastics are not widely recyclable. For example, burning plastics releases harmful gases, making energy recovery through incineration unsuitable for all types of plastic. While mechanical and chemical recycling methods exist, they are not always feasible for all types of plastic.

The recycling of plastic has also been impacted by global policies and markets. China's decision to no longer accept plastic waste from other countries disrupted the recycling industry, as other countries struggled to find alternative buyers. This highlighted the issue of limited markets for recycled plastic, as the production of new plastic is often cheaper and more profitable for companies.

Furthermore, plastic is lightweight and has a low recycling rate, making it challenging to collect and sort efficiently. Environmental groups and lawmakers are pushing for a reduction in single-use plastics and the implementation of "bottle bills" to encourage plastic bottle recycling. However, these efforts have faced resistance from the plastic and oil industries, which have a vested interest in continuing plastic production.

Despite these challenges, some states in the US, such as Oregon and Michigan, have successfully improved plastic bottle recycling rates through legislation. Overall, while plastic is not widely accepted at recycling plants due to economic, environmental, and technical barriers, there are ongoing efforts to improve plastic recycling rates and reduce plastic pollution.

Plastic is hard to collect, sort, and reprocess

Plastic is a rapidly growing segment of municipal solid waste (MSW). In 2018, the United States generated 35.7 million tons of plastic, with a recycling rate of 8.7% (3 million tons). While there is no data on how much plastic was recycled globally in 2018, worldwide plastic production that year was 360 million tons.

However, recycling plastic is challenging due to the complexities of collecting, sorting, and reprocessing it. Firstly, collecting plastic waste is expensive, and it is often more economical to produce new plastic than to collect and recycle used plastic. This is especially true when considering the thousands of different types of plastic, each requiring separate collection and processing.

Sorting plastic is crucial for successful recycling, as polymers can only be reused and retain their value if sorted to a high degree of purity. However, the variety of plastic types and colours, as well as packaging design, make sorting a complex task. For example, black plastic, plastic sleeves on PET bottles, and products with multiple layers often result in valuable materials being discarded. While technologies like optical detection systems aid in colour separation, the sorting process remains labour-intensive and time-consuming.

Finally, reprocessing sorted plastic is a detailed procedure. It involves shredding, washing to remove impurities, and further shredding into fine flakes before the plastic is ready for processing into granulate. The granulate then undergoes multiple quality inspections to ensure the purity and homogeneity of the final product. The complexity and cost of this process further hinder the recycling of plastic.

Overall, the challenges of collecting, sorting, and reprocessing plastic contribute to the low recycling rates observed, with most plastic ending up in landfills despite public efforts to recycle.

Alternatives to plastic and systems of reuse are being pushed for

The recycling of plastic is a challenging issue, with most plastic ending up in landfills despite public recycling efforts. This is due to the high cost of collecting and sorting plastic, the existence of thousands of different types of plastic that cannot be melted down together, and the degradation of plastic after one or two uses. As a result, alternatives to plastic and systems of reuse are being advocated by environmentalists and lawmakers.

One alternative to single-use plastic is reusable containers and packaging, which can eliminate the need for single-use plastic items in all sectors. Replacing just 20% of single-use plastic packaging with reusable alternatives can offer economic opportunities worth billions of dollars. Reusable products have lower greenhouse gas emissions and water usage over their life cycle compared to disposable alternatives. Additionally, reusables prevent the cutting down of trees, the mining of metals, and the drilling for fossil fuels associated with single-use disposable products.

Businesses can play a crucial role in driving the shift from single-use plastics to more eco-friendly materials. For example, some companies offer reusable lunch boxes and food containers on a deposit-return scheme, where customers pay a deposit when purchasing food in a refillable container and receive a refund when they return the empty container. This model has been successfully implemented in Switzerland and Germany, with high return rates and reduced waste.

There are also creative alternatives to single-use plastic items such as bags, wraps, and containers. For example, beeswax wraps are a natural alternative to cling film or plastic wrap. They are made from cotton infused with beeswax, resin, and jojoba oil, and are completely reusable and biodegradable. Another alternative is mushroom packaging, which is made from mycelium, the root-like structure of fungal strands. It functions like cardboard but is completely compostable and can be grown from waste materials, creating a closed-loop system.

In addition to reusable and biodegradable alternatives, some materials can directly replace single-use plastic. For instance, stainless steel is a durable and reusable alternative for water bottles, straws, and food containers. It is resistant to rust, easy to clean, and a healthier option than reusable plastic containers. Similarly, bamboo, a fast-growing renewable resource, is used to make utensils, toothbrushes, and clothing. These alternatives to single-use plastic can play a crucial role in reducing plastic pollution and its negative environmental impact.
