Plastic recycling is a challenging and often misleading process. Despite public awareness and efforts to recycle, the reality is that most plastic ends up in landfills or the environment. A 2022 report by the Organisation for Economic Co-operation and Development revealed that only 9% of all plastic produced has been recycled, with the majority, about 72%, ending up in landfills or nature. The recycling process itself is complex and costly, and plastic degrades with each reuse, making it difficult to recycle certain types of plastic more than once or twice without defects and contamination. This issue is further exacerbated by the increasing production and use of plastic worldwide, with half of all plastics in existence created in the last two decades. As a result, the plastic recycling problem is worsening, and new solutions, such as refill and reuse schemes, are being explored to address this global crisis.

What You'll Learn
Plastic degrades with each reuse
Mechanical recycling, the most common form of recycling plastic, involves grinding, melting, and reforming plastic. This process can be time-intensive and expensive, as it requires proper sorting and cleaning of materials. Furthermore, mechanical recycling can result in the production of microplastics, which can end up in the environment, contributing to pollution.
Chemical recycling, a newer method, turns problem plastics into oil or gas through industrial processes. This approach can handle plastics that mechanical recycling cannot, such as pouches, sachets, and black plastics. However, chemical recycling has not been widely adopted due to the high costs involved.
The challenges of recycling plastic have led to a global waste crisis. Most plastic ends up in landfills or the environment, with only a small percentage being successfully recycled. Despite public efforts to recycle, the reality is that recycling plastic is challenging and often uneconomical. This has resulted in a significant amount of plastic waste, with an estimated 8-11 million tons entering the ocean each year.
To address the plastic waste problem, experts advocate for a reduction in plastic use and a shift towards refill and reuse schemes. These schemes involve purchasing products in reusable containers from filling stations, eliminating the need for single-use plastics. Additionally, legislation banning single-use plastics and incentivizing customers to return plastic bottles is being proposed in some states.

Recycling plastic is costly
The cost of recycling plastic is influenced by several factors, and it can be more expensive than simply making new plastic. Firstly, there is the cost of the raw materials used to make virgin plastic, such as petroleum and natural gas, which have constantly rising prices. The cost of recycling plastic also depends on the price of oil, which has been exacerbated by rising oil and natural gas prices. The process of recycling plastic is also time-intensive and expensive. It involves sorting, cleaning, grinding, melting, and reforming the plastic, which can be challenging and costly, especially when dealing with mixed plastics that can cause issues like rapid degradation.
Additionally, there is a shortage of the costly infrastructure required for effective plastic recycling, particularly in rural areas that cannot afford it. This results in most plastic ending up in landfills or the environment. According to a 2022 report, 72% of plastic ends up in landfills or the environment, and only 9% of all plastic produced has been recycled. The complexity of plastic recycling is further highlighted by the fact that many types of plastic cannot be recycled more than once without acquiring defects and contaminants.
The economics of plastic recycling have also changed over time. Recycled plastic used to be cheaper than new "virgin" plastic, making it appealing to manufacturers. However, with the decrease in oil prices, freshly produced plastics have become more economically viable, as they offer a more predictable chemical composition. This shift in economics has reduced the market for recycled plastic, making it even more challenging to justify the costs of recycling infrastructure and processes.
Despite the challenges and costs associated with plastic recycling, it remains crucial for environmental reasons. The accumulation of plastic waste in our waterways and the impact on wildlife underscore the need to maximize the use of existing plastic and develop better recycling strategies. While recycling plastic may be costly, the alternative of producing new plastic contributes to the growing plastic pollution crisis. Therefore, it is essential to explore alternative solutions, such as refill and reuse schemes, to reduce the environmental impact of plastic waste.

Recycling plastic is time-intensive
Plastic recycling is a time-intensive process that involves multiple steps. Firstly, different types of plastic need to be sorted and separated, which is challenging given the thousands of different types of plastic in existence. This sorting process is crucial as different plastics have varying melting points and cannot be melted down together. The sorted plastic then needs to be cleaned and prepared for recycling. This involves removing any labels, adhesives, and contaminants such as food waste or liquids that can rot and spoil the plastic.
Once the plastic has been sorted and cleaned, it can be recycled through mechanical or chemical processes. Mechanical recycling involves grinding up the plastic, melting it down, and reforming it into new products. However, this process can be time-consuming and expensive, and it may cause the plastic to degrade, limiting its reusability. Chemical recycling, on the other hand, involves turning plastic into oil or gas through industrial processes, which can handle some plastics that mechanical recycling cannot.
The time-intensive nature of plastic recycling is further exacerbated by the lack of infrastructure in many areas. Rural areas, in particular, often lack the necessary infrastructure for collecting and processing plastic waste due to the high costs involved. Additionally, the contamination of plastic waste with non-recyclable materials, food waste, and other contaminants can hinder the recycling process and require additional time and resources for proper sorting and cleaning.
Despite the challenges, some places, such as Oregon and Michigan in the United States, have achieved successful plastic bottle recycling rates through the implementation of bottle bills that incentivize customers to return their plastic bottles. However, such efforts are often met with resistance from the plastic and oil industry lobbyists, and the overall rate of plastic recycling remains low, with most plastic ending up in landfills or the environment.

Plastic production is increasing
Despite efforts to reduce, reuse, and recycle plastic, experts predict that plastic production will increase by 40% in the next ten years. This is due to the massive investments made by fossil fuel companies in building plastic production facilities. Over $180 billion has been invested in the last seven years, and this will fund the construction of more facilities in the coming decade.
The increase in plastic production facilities is directly linked to the rise in fracking and shale gas technologies, which have lowered plastic production costs. The versatility of plastics has also contributed to the continued growth in production. Plastics have replaced materials such as wood, metal, and glass in many applications, particularly in packaging.
The consequences of this increased production are severe. Most of the plastic we produce ends up in landfills or the environment. According to a 2022 report, 72% of all plastic ends up in landfills or the natural environment, and only 9% of all plastic ever produced has been recycled. The remaining 19% has been incinerated, with an estimated 8 to 11 million tons of plastic waste entering the ocean each year.
While recycling is often touted as a solution, it is not a cure-all. Mechanical recycling, the most common method, involves grinding, melting, and re-forming plastic, which can be time-intensive and expensive. Furthermore, many types of plastic cannot be recycled more than once without acquiring defects and contaminants.
The real solution, as Ramsden from Greenpeace states, is to "turn off the plastic tap" and switch to systems of reuse and refill.

Plastic recycling rates are low
Plastic recycling rates are notoriously low. According to a 2022 report from the Organisation for Economic Co-operation and Development, 72% of plastic ends up in landfills or the environment, with only 9% of all plastic ever produced having been recycled. In the United States, only about 5% to 6% of plastics are recycled annually, and the situation is even worse in developing regions, where the recycling infrastructure is often lacking or insufficient.
There are several reasons why plastic recycling rates are so low. Firstly, plastic is cheap to produce and highly profitable, which has led to a dramatic increase in plastic production in recent years. This means that it is often easier and more cost-effective for manufacturers to source virgin materials than to recycle plastic.
Secondly, there is a shortage of the costly infrastructure required to recycle plastic effectively. Mechanical recycling, which involves grinding, melting, and re-forming plastic, can be time-intensive and expensive, especially when it comes to properly sorting and cleaning materials. Many types of plastic cannot be recycled more than once without acquiring defects and contaminants, and advanced processing facilities are needed to create a high-quality source stock of recycled plastic.
Additionally, the plastic recycling industry in developing regions is largely made up of small and medium-sized enterprises that lack access to capital and financing. Interest rates in these regions can be as high as 15-20%industry officials have misled the public about the recyclability of plastic. Despite knowing that plastic could not be economically recycled, these officials continued to promote the idea that plastic could be easily recycled and turned into new products. This has led to a situation where people put plastic into recycling bins, only for it to end up in landfills or be burned, contributing to environmental pollution and degradation.
To address the issue of low plastic recycling rates, experts have suggested a range of solutions, including switching to systems of reuse and refill, banning single-use plastics, implementing "bottle bills" that pay customers to return plastic bottles, and providing financial support to recycling businesses in developing regions.
