Recycling Plastic: Government Efforts And Challenges

Despite growing awareness of the world's plastic waste challenges, recycling rates remain low. In the US, only 5% of household plastic waste is recycled, and globally, the rate is estimated to be just 9%. This is due to a combination of factors, including the incompatibility of different plastics, which makes sorting costly and inefficient, the lack of education about plastic waste and recycling, and the economics of recycling, where virgin plastic is often cheaper than recycled plastic due to fossil fuel subsidies. Governments are trying to implement new legislation to tackle plastic pollution, but existing recycling practices are falling short of what is needed to address the global plastic crisis.

The United States, the world's largest plastic polluter, recycles only 5% of its plastic waste

The United States, one of the world's largest consumers of plastics, is also one of the biggest contributors to the global plastic waste problem. In 2019, the country's plastic waste generation was estimated at 73 million metric tons, which equates to over 220 kilograms per person. This was approximately five times the global average per capita. With plastic demand showing little sign of slowing, the US is projected to generate over 140 million metric tons of plastic waste by 2060.

Despite this, the US does not have the capacity to recycle all its waste domestically. In 2018, the US recycled 3 million tons of plastic, resulting in an 8.7% recycling rate for that year. However, according to a 2022 Greenpeace report, only 5% of the plastic waste generated by US households in 2021 was recycled, with almost 95% ending up in landfills, oceans, or the atmosphere in the form of tiny toxic particles. This is a stark decline from the country's peak recycling rate of 9.5% in 2014.

The stagnation and decline of the US's domestic plastic recycling rate can be attributed to various factors. For one, the US has been exporting large volumes of plastic waste to other countries, particularly China, and counting it as recycled, even though much of it was burned or dumped. However, with China's recent restriction on foreign waste imports, the US has seen a significant reduction in its waste exports, further straining the already struggling recycling system.

Another factor is the reality that most plastic is simply not recyclable. Corporations have long promoted plastic recycling as the solution to plastic waste, but the truth is that a switch to reusable and refillable systems is needed. This is evident in a finding by Greenpeace USA that even bottles and jugs were not completely recycled or recyclable. Furthermore, not a single type of plastic packaging in the US meets the definition of recyclable used by the FTC or the Ellen MacArthur Foundation's new plastic economy initiative.

The US's struggle with plastic waste and recycling has significant environmental and health impacts. Large amounts of plastic leak into the oceans annually, contributing to the deaths of thousands of marine animals and the growing presence of microplastics in our food and beverages. With plastic taking hundreds of years to break down, the situation is dire, and urgent action is needed to address this global crisis.

The economics of recycling are stacked against success, with virgin plastic being cheaper than recycled plastic

The economics of recycling are challenging, and the system itself is deeply flawed. The high cost of sorting incompatible plastics and the limited availability of high-quality recycled plastics are significant factors in the low recycling rates. The price of virgin plastic, derived from petroleum, has been driven down by a global oversupply of industrial chemicals, mainly due to a boom in shale gas and petrochemical production in China and the US. This has resulted in an economically unviable situation for recycled plastics, which struggle to compete on price. Virgin plastics are also often subsidised by fossil fuel subsidies, further exacerbating the issue.

The environmental impact of virgin plastics is significant, contributing to fossil fuel extraction and increasing greenhouse gas emissions. Recycled plastics, on the other hand, have a lower carbon footprint and reduce landfill waste. However, they face processing challenges due to the need to remove contaminants, impacting production efficiency. The limited availability of high-quality recycled plastics and the additional processing required can make it challenging for businesses to source and use them.

Despite these challenges, there is a growing awareness of the world's plastic waste crisis, and consumers, brands, and governments are increasingly committed to curbing plastic pollution. Recycling is crucial for supporting a circular economy and reducing waste. However, the current strategies for managing waste are falling short, and the low price of virgin plastic discourages the use of recycled materials.

To address these issues, systemic change is required, driven by policy and innovation. Governments are implementing new legislation to tackle plastic pollution, and businesses are paying more attention to their environmental, sustainability, and governance goals. However, the success of recycling efforts relies on education and infrastructure, with many people worldwide lacking access to essential waste management and recycling facilities.

Consumers play a crucial role in plastic recycling, but education about plastic waste is often lacking

Consumers are key to plastic recycling, but many people lack access to education about plastic waste and recycling. In one global survey, only 51% of respondents said they had received education about recycling at school. This lack of knowledge can make it difficult for people to understand which items can be recycled and which cannot. For instance, a quarter of people surveyed in one study were unsure about the recycling rules in their state.

The consequences of this lack of education are far-reaching. Without access to waste management services, many people have no choice but to burn or dump their trash. Even when recycling infrastructure is available, not all plastics are accepted at facilities, and the system itself is deeply flawed. Most plastics are incompatible, making sorting costly and inefficient. Only PET (#1) and HDPE (#2) are widely recycled.

Education about plastic waste and recycling can help people make informed decisions when buying plastic products. While educational materials on plastic recycling are available through professional and industry associations, foundations with an environmental focus, university courses, and short courses offered by private companies, these courses can be costly and less accessible to students and the general public.

Some governments are taking steps to address plastic pollution and improve recycling rates. For example, the German government has created economic incentives for recycling, including fines for improper sorting and deposits on beverage containers that are repaid when recycled. Manufacturers are encouraged to learn about recycling and waste reduction through the Green Dot System, which is now implemented in 32 European countries.

Governments are implementing new legislation to tackle plastic pollution, but existing practices are falling short

Governments are increasingly introducing new legislation to address the plastic pollution crisis. However, existing recycling practices are often insufficient, and a range of challenges hinder their effectiveness.

Plastic pollution is a significant global issue, with plastic waste causing harm to natural resources, ecosystems, and public health. The United States, the world's largest plastic polluter, recycles only 5% of its household plastic waste. This figure is slightly higher globally, with 9% of plastic waste being recycled, while the vast majority, a shocking 91%, is incinerated, landfilled, or improperly managed.

To combat this crisis, governments are taking legislative action. For instance, US Senators Tom Udall and Sheldon Whitehouse, along with Representatives Alan Lowenthal and Lloyd Doggett, have proposed or reintroduced bills aimed at tackling plastic waste. These include the REDUCE Act, which seeks to impose a fee on virgin plastic resin used for single-use products. This act intends to incentivize the use of recycled materials, promote a circular economy, and reduce plastic pollution.

While these legislative efforts are a step in the right direction, existing recycling practices are falling short. The recycling system is flawed due to the incompatibility of different plastics, making sorting a costly and inefficient process. Only certain types of plastic, such as PET and HDPE, are widely recycled, while flexible packaging and multi-layered packets are extremely difficult to recycle. Additionally, the economics of recycling pose a challenge, as virgin plastic is often cheaper than recycled plastic due to fossil fuel subsidies.

To address these shortcomings, a fundamental shift in our relationship with plastic is necessary. This includes improving recycling infrastructure, increasing consumer education about plastic waste, and driving innovation to make recycled materials more cost-effective.

The recycling system is deeply flawed, with most plastics being incompatible and difficult to repurpose

The recycling system is flawed, and most plastics are incompatible and difficult to repurpose. Plastic is a generic term for a vast array of different products, from paints and glue to hard thermoplastics. This presents a significant challenge to recycling, as different polymers have distinct properties and require specific recycling processes. Mechanical recycling, for instance, may work for one type of polymer but be ineffective for another. The presence of adhesives, pigments, co-polymers, and other additives in plastic products further complicates the recycling process.

The complexity of plastic's chemical makeup and its durability make it inherently difficult to recycle. Over 13,000 chemicals in plastics pose health hazards, and the recycling process can increase their toxicity. This is because, during recycling, the chemicals added during the initial production mix with those absorbed by the plastic throughout its lifecycle. As a result, recycled plastic often becomes more toxic with each cycle, limiting its potential for reuse.

The process of recycling plastic is also energy-intensive and costly. Proper recycling requires separating different types of plastics, which is time-consuming and challenging, especially with black plastic items that sorting machines struggle to identify. Certain types of plastics, such as low-density polyethylene (LDPE), also need to undergo chemical recycling to be food-safe, adding to the complexity and expense.

The economics of recycling further hinder its success. Virgin plastic, often subsidized by the fossil fuel industry, is cheaper than recycled plastic, discouraging the use of recycled materials. Additionally, flexible packaging, despite being convenient, is incredibly difficult to recycle due to contamination and complex composition. These factors contribute to the challenge of repurposing most plastic products, highlighting the flaws in the current recycling system.
