Despite public efforts to recycle plastic, it has become evident that a large proportion of plastic waste still ends up in landfills. A 2022 Greenpeace report revealed that although people put plastic into recycling bins, very little of it is actually recycled. This is due to the fact that plastic is not designed to be recycled, and the global waste industry often sends plastic waste directly to landfills or incinerators. In 2021, it was estimated that 85% of US plastic waste went to landfills, with only 5-6% being recycled. This issue is not unique to the US, as similar challenges with plastic recycling are faced in other parts of the world.

What You'll Learn
Plastic recycling rates are low
The low recycling rates are also attributed to the nature of plastic itself. Plastic is not designed to be recycled, and the wide variety of plastic polymers, with at least 267 types, further complicates the recycling process. When different polymers are mixed, it can lead to defects in the manufacturing process. Advanced processing facilities are required to create a high-quality source stock of recycled plastic, but the lack of advanced recycling infrastructure, particularly in developing regions, hinders this process. As a result, most plastic is currently being down-cycled into low-quality products, which are not recycled again.
The plastic recycling industry in developing regions faces additional challenges. Small and medium-sized enterprises, which comprise over 90% of the industry, often lack access to capital and financing. High-interest rates in these regions, ranging from 15-20%, further impede their ability to invest in recycling infrastructure and technology. Additionally, the economies of scale favour the use of virgin materials over recycled plastics, making it more cost-effective for manufacturers to source new material.
Furthermore, the recycling infrastructure in many places is inadequate to manage the growing waste generation. Municipal budgets struggle to keep up with the increasing consumption and the high costs associated with collecting and processing unsegregated household waste. In developing countries, a significant portion of recycling activities are informal, with individuals and small enterprises filling the gaps left by inadequate municipal waste management systems. However, without proper support and inclusion in market systems, these informal recyclers cannot fully address the waste management challenges.

Plastic is not designed to be recycled
The reasons behind the low percentage of plastic recycling are many. Firstly, not all plastic is widely recyclable. For example, bioplastics, composite plastic, plastic-coated wrapping paper, and polycarbonate are all non-recyclable plastics. Secondly, even when plastic is technically recyclable, it may not be recycled due to economic and technical reasons. Recycling plastic is costly, and the process becomes even more expensive when additional steps such as post-consumer selection and washing are required. In countries with high electricity prices, it might be more profitable to incinerate plastic instead of recycling it.
Additionally, there is a lack of demand for recycled plastic. Despite the existence of recycling facilities and technologies, there are virtually no domestic manufacturers willing to buy recycled plastic and turn it into something new. This is because creating new plastic from raw materials is still relatively cheap, especially with the low cost of oil, which is used to make plastic. As a result, recycling plastic waste cannot be economically justified.
Furthermore, the public has been misled about the recyclability of plastic. The plastics industry has spent millions on advertising campaigns promoting plastic recycling, even though they knew as early as the 1970s and 1980s that plastic could not be economically recycled. These campaigns were designed to sell more plastic by reassuring consumers that recycling was an effective solution to environmental concerns. As a result, consumers have been led to believe that their plastic waste is being recycled when, in reality, it is often being landfilled or incinerated.
Finally, plastic waste is not always properly sorted, which can lead to contamination and further reduce the likelihood of it being recycled. For example, thin bags or films can clog recycling machines if not separated properly, and plastic with food residues is usually not recycled. Ultimately, while some progress is being made in recycling certain types of plastic, the reality is that most plastic is not designed to be recycled and ends up contributing to landfill waste and environmental pollution.

Plastic is a valuable resource
However, despite its usefulness, plastic is often treated as a disposable commodity. Around 50% of plastic is used just once and thrown away, and approximately 500 billion plastic bags are used worldwide each year, with a staggering average "working life" of just 15 minutes. Over the last decade, we have produced more plastic than in the entire previous century.
The issue of plastic waste is further compounded by the fact that most plastic items collected for recycling are not actually recycled. A Greenpeace report found that while people put plastic into recycling bins, almost none of it is truly recycled, with less than 5% of plastic being repurposed. The rest ends up in landfills or is incinerated. This is because plastic is not designed to be recycled and there is often no demand for recycled plastic products.
Despite these challenges, there is a growing focus on a circular economy for plastics. This involves processing, using, and reusing plastics, with the materials being recycled and returned to a base state that can be reused. Plastics can be mechanically recycled into new items or chemically recycled to create new opportunities for use within the economy. Additionally, with advancements in technology, plastics can now be produced from renewable sources such as waste biomass, CO2, and even animal waste products.
Overall, while plastic waste is a significant issue, plastic remains a valuable resource with a variety of applications. The key lies in reducing plastic consumption, increasing recycling efforts, and transitioning to renewable sources for plastic production.

Plastic waste management techniques
Plastic waste management is essential to protect our environment, economy, and future. Here are some plastic waste management techniques:
Recycling
Recycling is the process of converting waste into reusable material. However, it's important to note that not all plastics can be recycled. Only Type 1 (PET) and Type 2 (HDPE) plastics are commonly recycled. The recycling process involves collecting, sorting, washing, shredding, melting, and remolding plastics into new products. Mechanical sorting separates plastics from other materials like paper, glass, and metals. Chemical recycling, or advanced recycling, disassembles plastics into their chemical constituents or transforms them into useful products.
Biodegradation
Biodegradation is an environmentally friendly method of disposing of plastic waste. It involves using microorganisms like bacteria, fungi, and enzymes to break down plastic material into simpler substances such as water, carbon dioxide, and biomass.
Enzyme-based Recycling and Edible Packaging
Enzyme-based recycling and edible packaging are innovative approaches to plastic waste management. Enzymes can break down plastics, and in the future, we may even be able to eat our packaging.
Policy and Regulation
Governments play a crucial role in plastic waste management by implementing policies to regulate plastic use and promote efficient waste management. Policies can include banning single-use plastics, incentivizing recycling through "bottle bills," and setting targets for manufacturers to make their products recyclable or compostable.
Consumer Awareness and Reduction of Plastic Consumption
Consumer awareness and behavior change are vital. People should be informed about the limitations of recycling and encouraged to reduce plastic consumption and find sustainable alternatives.

Plastic recycling is a false promise
Firstly, plastic recycling as it stands today is harmful and cannot be considered a circular process. The recycling of plastic often involves toxic materials and harmful chemicals, which are released into the environment during the reprocessing stage. The reprocessing of plastic also requires large amounts of energy, which is typically derived from burning fossil fuels, further contributing to climate change. Even when recycled, plastics are usually "downcycled", meaning they are made into items of lesser value and quality, such as plastic fleece jackets or carpet fiber, which will eventually end up as waste.
Secondly, the plastic industry has been perpetuating the myth that plastics are recyclable by promoting the idea of "plastics circularity". They claim that plastics can be reused endlessly without negative consequences, which is false. In reality, plastic recycling processes drive plastic pollution and have toxic impacts on the environment and communities. The industry has invested heavily in lobbying and campaigns to promote mechanical and advanced recycling, distracting from the real solution, which is to reduce plastic production and switch to sustainable alternatives.
Thirdly, the public's positive perception of plastic recycling has been deliberately cultivated by manufacturers and product-packagers. They often label products as "widely recyclable" without differentiating between what is technically recyclable and what is actually recycled in practice. This misleading information gives consumers a false sense of environmental friendliness, when in reality, most plastic ends up in landfills or is incinerated. For example, black plastic takeout containers have a very low chance of being recycled, yet consumers may see "widely recyclable" printed on them.
Finally, recycling alone cannot solve the problem of plastic pollution. While recycling can be a way to mitigate plastic pollution, it must be coupled with a drastic reduction in plastic production. Consumers can play a role by reducing their plastic consumption, reusing and repurposing plastic items, and supporting plastic-free solutions in their communities and at a systemic level.
In conclusion, plastic recycling, as it currently stands, is a false promise that distracts from the real solutions needed to address plastic pollution.
