California's Plastic Recycling Efforts: How Effective?

California has been taking steps to address its plastic recycling problem. Despite the state's efforts to achieve a circular economy, it has faced challenges such as contamination and the decline of plastic exports to other countries. While there are varying estimates, statistics indicate that only a small percentage of plastics are recycled, with most ending up in landfills or discarded into the environment. California has introduced legislation, such as Senate Bill 343, Truth in Labeling for Recyclable Materials, to address these issues and improve the state's recycling system.

Plastic exports to other countries

California has been a top exporter of plastic waste to other countries, with about one-third of its recycling being exported. In 2014, California exported almost 1.3 million tons of plastic scrap, and this number decreased to less than 50,000 tons in 2022. In March 2021, California exported 7.4 million kg of plastic waste to Non-OECD countries, with 3.8 million kg going to Malaysia. California accounts for 27% of the United States' plastic waste, which is the largest exporter of plastic waste to Non-OECD countries.

The main countries that California has been exporting plastic waste to are Vietnam, Malaysia, Thailand, and Indonesia. This shift in exports occurred after China implemented stricter regulations on the import of foreign plastic in 2017, resulting in a 92% drop in US plastic waste exports to China.

California has been directing its plastic waste exports to countries with poor waste management and weak environmental protections. This has caused harm to the global environment and communities and the health of people worldwide. The plastic waste exported from California has not been safely recycled and has contributed to plastic pollution in the ocean and social and environmental harm in receiving countries.

To address this issue, California has implemented policies to reduce plastic waste and increase recycling. In 2014, California became the first state to implement a ban on single-use plastic bags and a tax on recycled paper bags, reusable plastic bags, and compostable bags. In 2021, California passed AB 881, which states that jurisdictions will no longer receive diversion credit when exporting mixed plastic recyclables. This will encourage more remanufacturing of recycled materials within the state.

Plastic scrap exports

California has been taking steps to address the global problem of plastic waste. The state has set a goal of recycling 75% of its waste and is working towards achieving a circular economy. However, it has faced challenges in its plastic recycling efforts, with at least 85% of single-use plastics ending up in landfills.

In recent years, California's plastic scrap exports have declined significantly. In 2022, the state exported less than 50,000 tons of plastic scrap, a sharp decrease from the nearly 1.3 million tons exported in 2014. This reduction is partly due to the state's efforts to reduce mixed plastic exports and increase domestic remanufacturing of recycled materials.

Historically, California received landfill diversion credit when exporting recyclable materials to other countries. However, with the passage of Assembly Bill 881 in 2021, jurisdictions will no longer receive diversion credit for exporting mixed plastic recyclables. This bill aims to ensure that only responsibly exported plastic material is counted as diversion from landfills and encourages more remanufacturing within the state.

California's plastic scrap exports have been impacted by global regulations and market shifts. China's retreat from the global scrap plastic trade since 2018 has significantly reduced the export volume from the US. In 2017, China imported 1.2 billion pounds of US scrap plastic, but by 2023, the US exported only 918 million pounds of scrap plastic, with very little going to China.

In 2023, the largest export markets for US scrap plastic were Canada, Mexico, India, Malaysia, and Vietnam. California's exports to Canada and Mexico are transported via truck and rail. While plastic scrap exports from the US have decreased overall, exports of Polyethylene Terephthalate (PET) scrap have increased, driven by cost-saving opportunities and growing recycling capacities in other regions.

Plastic recycling labels

California has taken steps to address the global problem of plastic waste. The state has set a goal to recycle 75% of all the waste it produces. However, it has been challenging to achieve this goal due to the complex nature of plastic recycling.

One of the significant challenges in plastic recycling is accurately labelling recyclables. To address this, California introduced Senate Bill 343, also known as the "Truth in Labeling for Recyclable Materials" or "Truth in Recycling" law. This bill aims to ensure that only products that are regularly collected and processed for recycling in the state can be labelled as recyclable. It requires CalRecycle to publish data about the types of materials actually recycled in California, which manufacturers must use to assess whether their products can be considered recyclable. The bill also outlaws the sale of products labelled as recyclable if they are not regularly recycled in the state.

The implementation of SB 343 involves several steps. By January 1, 2024, CalRecycle was required to complete a statewide analysis to identify commonly recycled materials. The preliminary findings were published in December 2023, with revised findings released in December 2024. The law also mandates ongoing studies, with the second study to be completed by 2027 and subsequent studies every five years.

The resin identification code, or the number framed within the triangular arrows symbol, is crucial in plastic recycling labels. Only plastics with codes 1 or 2, such as plastic bottles and jugs, are widely recycled across the United States. Codes 3 through 7 may or may not be recycled depending on local waste management practices. Some cities, like Sacramento and San Francisco, do recycle items with codes 3 to 7. However, the bill initially proposed that only products with codes 1 and 2 bear the chasing arrows recycling symbol.

The accurate labelling of recyclables is essential to reducing contamination in the recycling stream. By providing clear information to consumers, California aims to improve the quality of recycled materials and work towards a more circular economy.

Plastic waste management

California has been taking steps to address its plastic waste problem and improve its recycling infrastructure. The state has set a goal to recycle 75% of its waste and is working towards building a circular economy.

One of the key challenges in plastic waste management is the confusion surrounding what is actually recyclable. Many single-use plastic items carry the recycling symbol, even though they may not be recyclable in practice. To address this, California introduced Senate Bill 343, or the "Truth in Labeling for Recyclable Materials" act. This bill aims to clarify the meaning of "recyclable" and set boundaries on the use of the recycling symbol. Under this legislation, only plastic items with a resin identification code of 1 or 2 (plastic bottles and jugs) will be considered widely recyclable.

California is also tackling the issue of plastic waste by reducing the amount of plastic that ends up in landfills. In 2016, California voters approved the nation's first state ban on single-use plastic bags, and certain trash bags are now required to contain at least 10% recycled plastic. Additionally, the state has implemented the Beverage Container Recycling Program, where consumers pay a California Refund Value (CRV) on eligible beverage containers, which is refundable upon return.

The state is also focusing on increasing the market demand for recycled plastic by encouraging the use of recycled content in new products. California processors and manufacturers may receive incentive payments for using recycled CRV plastic. The state is also working on responsible recycling markets and ensuring that only plastic material exported responsibly will count as diversion from landfills.

California is a leader in environmental advocacy and continues to implement packaging waste reduction initiatives, especially those targeting single-use plastics. The Plastic Pollution Producer Responsibility Act (SB 54), enacted in September 2022, established a comprehensive extended producer responsibility program for managing packaging and food ware waste. The state also has initiatives in place to address food waste, such as banning "sell by" dates and standardizing food date labeling terminology.

Plastic recycling rates

California has been taking steps to improve its plastic recycling rates, which have historically been low. The state has set a goal of recycling 75% of its waste, including plastic, and is working to build a circular economy by addressing the issue of contamination and increasing the remanufacturing of recycled materials within the state.

One challenge California faces is that many single-use plastic items are not recycled, even if they carry the recycling symbol. This has led to proposals to limit which plastics bear the recycling symbol, with some suggesting that only plastic bottles and jugs (coded 1 and 2) should be allowed to display it. This would help to reduce confusion among consumers, who often find recycling confusing.

Another issue is that California has previously exported a significant amount of its plastic scrap to other countries, such as China, for recycling. However, this has become more difficult due to policy changes in those countries and the decline in the global market for recycled plastics. In 2022, California exported less than 50,000 tons of plastic scrap, compared to almost 1.3 million tons in 2014.

To address these issues, California has introduced a package of new laws, including Senate Bill 343, or the "Truth in Labeling for Recyclable Materials" bill. This bill aims to provide clearer definitions of what is considered recyclable and improve the state's recycling infrastructure. The state is also working to increase the market for recycled materials and improve the collection and remanufacturing of these materials within California.

While the exact plastic recycling rate in California is difficult to determine, it is estimated that only a small percentage of plastic waste is successfully recycled. Some estimates place this number at between 5% and 9%, while others suggest that a higher percentage of plastic that reaches recycling centers is recycled, but the majority of plastic waste is never collected for recycling in the first place.
