What You'll Learn
Plastic recycling rates are low
Plastic recycling rates are extremely low, with less than 10% of plastic ever being recycled. This is due to a variety of factors, including the high cost of recycling, the lack of advanced recycling infrastructure, and the variety of plastic types that cannot be easily sorted and melted down together.
The process of recycling plastic is complex and expensive. It involves collecting, sorting, and melting down plastic waste, which can be challenging and costly, especially when it comes to the wide variety of plastic types. There are hundreds of different kinds of plastic, and they cannot be melted down together without affecting the material properties and potentially causing defects in the manufacturing process. This means that advanced processing facilities are needed to create a high-quality source stock of recycled plastic. However, the majority of plastic is currently being down-cycled into low-quality products due to the use of rudimentary technology.
Another factor contributing to the low recycling rates is the lack of access to formal waste management services globally. It is estimated that 3.5 billion people lack access to these services, and the municipal budget cannot keep up with the growth in consumption. In developing countries, 80-90% of recycling activities are informal, and these urban mining entrepreneurs save municipalities millions by preventing waste from being sent to landfills. However, the lack of access to capital and the high interest rates in these regions make it challenging for small and medium-sized enterprises, which make up over 90% of the plastic recycling industry, to participate in the recycling process.
The oil and gas industry has also been accused of misleading the public about the recyclability of plastic. Despite knowing that plastic could not be economically recycled, they used the promise of recycling to sell more plastic. Industry officials have been unable to explain how they plan to achieve a 100% recycling rate, and environmentalists and lawmakers are now pushing for legislation that bans single-use plastics and promotes the recycling of plastic bottles.
The low plastic recycling rates have significant environmental and economic impacts. It is estimated that 95% of plastic packaging material, valued at USD 80-120 billion annually, is lost to the economy. Additionally, 32% of plastic packaging escapes collection systems, polluting the ocean and clogging urban waterways. The negative impact of this plastic waste is estimated to cost society USD 40 billion annually.

Plastic companies mislead the public
Plastic recycling is practically impossible, and the problem is only getting worse. Despite this, plastic companies have been misleading the public for decades by putting recycling symbols on their products, implying that they can be recycled. However, the truth is that most plastic ends up in landfills, as revealed by a Greenpeace report. The report found that while people put plastic into recycling bins, almost none of it is actually recycled. This misinformation has contributed to the mounting plastic pollution crisis.
The oil and gas industry has played a significant role in this deception. An NPR and PBS Frontline investigation revealed that these companies used the promise of recycling to sell more plastic, even though they knew it was not economically feasible on a large scale. They focused on creating single-use plastics that would generate continuous demand for their products. The plastics industry, including companies like Exxon, Chevron, Dow, and DuPont, spent millions on advertising campaigns to promote the message that plastic could be recycled.
Industry insiders have referred to plastic recycling as "uneconomical" and acknowledged that it "cannot be considered a permanent solid waste solution." Despite this, they continued to deceive the public with outdated information and false claims. The Society of the Plastics Industry, now known as the Plastics Industry Association, played a key role in this deception by establishing the Plastics Recycling Foundation and launching campaigns focused on the sector's commitment to recycling. They introduced the "chasing arrows" symbol, which has been widely recognized as a sign of recyclable plastic, even though experts have long considered it misleading.
The American Chemistry Council, an industry lobby group, initially denied the Greenpeace report's findings, claiming that the industry is "on the cusp of a circularity revolution" in plastic recycling. However, their own reports from the 1970s and 1980s indicated that they were aware of the challenges of plastic recycling. Environmentalists and lawmakers are now pushing for legislation to ban single-use plastics and hold these companies accountable for their misleading practices.

Plastic waste ends up in landfills
Plastic waste ending up in landfills is a significant environmental concern. Landfilling is a common method for disposing of plastic waste, but it leads to several ecological issues. Plastic waste in landfills undergoes long-term degradation, resulting in changes to its chemical structure and the release of toxic substances. This process contributes to the formation and spread of microplastics, which have hazardous effects on various floral and faunal species.
The problem is exacerbated by the fact that a significant portion of plastic waste is not properly managed. Mismanaged plastic waste, which includes plastic that is not recycled, incinerated, or stored in sealed landfills, is at risk of polluting the environment. It is leaked into rivers, lakes, and oceans, with a higher probability of this occurring in low-to-middle-income countries due to poorer waste management infrastructure. As a result, most of the plastic waste in the oceans comes from middle-income countries, particularly in Asia.
Additionally, recycling plastic has proven to be challenging. Despite public efforts to recycle plastic, only a small percentage of it is actually repurposed. A Greenpeace report found that while 52% of recycling facilities in the US accept plastic cups and containers, less than 5% of this plastic is given a new purpose. Similarly, the National Association for PET Container Resources discovered that only 21% of plastic bottles collected for recycling were turned into new products in 2017.
The oil and gas industry has been accused of misleading the public about the recyclability of plastic. An NPR and PBS Frontline investigation revealed that the industry used the promise of recycling to sell more plastic, even though they knew it was not economically feasible on a large scale. Industry officials have been unable to explain how they plan to achieve a 100% recycling rate, which they have committed to reaching by 2040.
Furthermore, the variety of plastic types poses a challenge to recycling efforts. There are hundreds of different kinds of plastic, and they cannot be melted down together. Sorting through and processing plastic waste is expensive, and new plastic is relatively cheap, making it difficult to justify the cost of recycling. As a result, even when plastic is placed in recycling bins, it often ends up in landfills.

Plastic recycling is expensive
Secondly, the recycling process itself is energy-intensive and costly. It involves collecting, sorting, and melting down the plastic, which requires specialized machinery and facilities. The high cost of electricity in some countries can make it more profitable to incinerate plastic waste instead of recycling it. Additionally, the market for recycled plastic is fragmented, making it challenging for sellers to find buyers, especially with the recent ban on low-quality recyclables imports in China.
Furthermore, the oil and gas industry, which produces new plastic, has kept the cost of virgin plastic low compared to recycled plastic. The availability of cheap new plastic discourages investment in recycling infrastructure and creates a competitive environment that makes recycled plastic less attractive.
While there is a growing demand for recycled plastic as manufacturers shift towards sustainability, the current recycling capacity is unable to handle the volume and variety of plastic waste generated. This results in increased recycling costs and lower recycling rates, with many localities resorting to incineration or landfill as cheaper alternatives.
Despite the challenges, there is optimism that recycling will become more cost-effective in the future. The development of new technology and infrastructure could drive down recycling costs and make it economically viable to recycle plastic on a larger scale. Additionally, the environmental and social benefits of recycling, such as reduced pollution and job creation, may justify the costs for some.

Plastic alternatives are needed
Plastic recycling is a challenging issue, with reports indicating that most plastic ends up in landfills rather than being recycled. This highlights the need for effective plastic alternatives to reduce environmental impact. One of the primary considerations when exploring plastic alternatives is their end-of-life impact, raw material extraction, water and land use, and the release of hazardous chemicals.
Reusable and refillable packaging is one of the most environmentally friendly options, as it reduces the need for single-use materials. Shifting to unpackaged goods or buying in bulk and using personal containers are simple ways to minimize waste. Additionally, biodegradable alternatives, such as compostable bioplastics, offer a promising solution. However, the challenge lies in ensuring proper disposal, as they require specific conditions, such as industrial anaerobic composting facilities, to break down effectively.
Plant-based plastics, or bioplastics, are another alternative, particularly for food packaging. For instance, companies like B'zeos and Notpla have developed edible cutlery, condiment packets, and biodegradable straws made from seaweed. These products are designed to biodegrade completely within a short time frame. PHA (polyhydroxyalkanoates), produced through bacterial fermentation, is another innovative bio-based and biodegradable plastic alternative. It is compostable at home and has the potential to become a strong competitor in the market.
Silicone, derived from silica stone, water, and natural gas-derived methanol, shares many characteristics with plastic but is considered safer and more environmentally friendly. It is strong, flexible, and capable of withstanding extreme temperatures without leaching toxic residues or microplastics. While technically recyclable, the challenge lies in finding facilities equipped to accept and recycle silicone products.
Other alternatives include natural fibers such as coconut fiber, hemp, husk, oat hulls, cotton burs, and jute for packaging and shipping materials. Additionally, a group of scientists from Rutgers and Harvard universities has developed an antimicrobial and biodegradable spray-on coating made from plant cellulose for produce and other food items. This innovation could potentially eliminate the need for plastic packaging for fruits, vegetables, and meat.
While these alternatives show promise, it is important to recognize that they may not always be cheaper than fossil fuel-based plastics. Scaling up production and optimizing processes will be crucial in making these alternatives more accessible and cost-effective.
