Plastic recycling is the process of taking used or discarded plastic and processing it into new materials and products. The most commonly recycled plastics are Polyethylene terephthalate (PET), High-density Polyethylene (HDPE), and Polypropylene (PP). However, not all plastics can be easily recycled, and the effectiveness of plastic recycling has been questioned. For example, in 2021, only about 5-6% of U.S. plastic waste was recycled. Despite this, recycling plastic is still important as it helps to keep plastic out of the environment and reduces the need for new plastic made from raw materials, saving energy and carbon emissions.

What You'll Learn
Recycling plastic reduces pollution and saves animal species
Recycling plastic is important, but it is not a perfect solution to plastic pollution. Plastic recycling has been promoted as the solution to plastic pollution by corporations and governments since the 1970s. However, despite these efforts, plastic pollution and its toxic impacts continue to grow.
The reality is that the majority of plastics do not end up being recycled. In the United States, only about 12% of plastic waste is recycled, with the rest ending up in landfills. This is a huge problem, as plastic can take up to 1,000 years to decompose. Recycling plastic helps to keep it out of landfills, streets, parks, and oceans, reducing the risk of plastic leaching into the environment. Recycling also helps to reduce the need for new plastic made from raw materials, saving energy and carbon emissions in the process. It takes 75% less energy to make a plastic bottle from recycled plastic compared to new plastic.
However, the plastic recycling process itself may contribute to pollution. Research suggests that the handling of plastic in recycling facilities, such as chopping, shredding, and washing, may turn a significant portion of the waste into microplastics. These microplastics are tiny, toxic particles that can have serious health impacts on both humans and animals. Scientists have found microplastics in the blood and placentas of humans, as well as in hundreds of animal species, including marine mammals, seabirds, and fish.
Plastic pollution poses a significant threat to wildlife, with over 800 marine and coastal species impacted by entanglement and ingestion of plastic. Plastic debris can block or pierce the digestive tracts of animals, choke them, or cause them to feel full and starve. It can also introduce chemicals that disrupt the reproductive systems of many species.
While recycling plastic is not a perfect solution, it is still an important part of reducing pollution and saving animal species. It helps to keep plastic out of the environment and reduces the need for new plastic production. However, it is clear that more needs to be done to address the plastic pollution crisis, such as reducing plastic production and investing in better recycling infrastructure.

Recycling reduces the need for new plastic made from raw materials
Plastic recycling is the process of taking used or discarded plastic and processing it into new materials and products. Recycling plastic is important as it helps to keep it out of our streets, parks, oceans, and the environment. Recycling also helps to limit the impact of plastic use on the environment by reducing plastic waste and pollution.
Recycling plastic reduces the need for new plastic to be made from raw materials. This is because recycling plastic saves energy and carbon by requiring less energy to make products from recycled plastic compared to new plastic. For example, it takes 75% less energy to make a plastic bottle using recycled plastic compared to new plastic. Recycling also saves precious natural resources such as water, petroleum, natural gas, and coal. Petroleum consumption, for instance, can be reduced by around 40% by recycling old plastic waste. Recycling plastic also saves landfill space, with 7.4 cubic yards of landfill space saved by recycling 1 ton of plastic.
Recycling is one part of the solution to the plastic waste problem. While recycling plastic is becoming more efficient and effective, plastic pollution continues to increase due to our ever-increasing reliance on plastic. Recycling is, therefore, the third part of the solution, after reducing our consumption and repurposing as much as possible by reusing or remaking. The easy-to-recycle materials such as PET, HDPE, and PP should be remanufactured to reduce the need for new plastics.
The UK, for example, has implemented policies to improve recycling systems, such as a new Plastics Tax, where packaging with less than 30% recycled content will be taxed. However, the UK currently sends most of its recycled plastic packaging overseas, where it is turned into new products. This can make it more challenging to track and monitor the recycling process and increases the possibility of recycling being dealt with irresponsibly.

Recycling saves energy and conserves natural resources
Recycling is an essential activity that helps save energy and conserve natural resources. It is a process that involves taking used or discarded plastic and transforming it into new materials and products. By recycling, we can reduce the need to extract natural resources such as timber, water, and minerals for new products. This helps to conserve our planet's precious resources for future generations.
Recycling plastic specifically helps to keep it out of our streets, parks, and oceans. It also changes our perception of plastic from rubbish to a valuable resource. This shift in perspective makes us less likely to litter, benefiting wildlife and the environment. Recycling plastic also increases the availability of recycled plastic, enabling more businesses to incorporate it into their products and empowering consumers to make more sustainable choices.
The recycling process typically consists of three steps: collection, recovery, and reuse. First, recyclables are collected through methods such as curbside collection, drop-off centers, or deposit/refund programs. They are then sent to a recovery facility to be sorted, cleaned, and processed into usable materials. Finally, these materials are purchased and used to create new products at recycling plants or similar facilities.
Recycling saves energy by reducing or eliminating the need to manufacture products from scratch. The process of extracting, refining, and processing natural resources is energy-intensive. By using recycled materials, manufacturers can produce the same goods with less energy and expense. This is because recycled materials have already undergone the initial refining and processing stages.
Additionally, recycling certain materials offers significant energy savings. For example, recycling just 10 plastic bottles saves enough energy to power a laptop for more than 25 hours. Similarly, the energy required to produce one virgin aluminum can is enough to manufacture 20 recycled cans. Recycling these materials helps reduce the need to introduce new materials into the production cycle, minimizing energy consumption.

Recycling reduces landfill waste
Recycling is an integral part of waste management strategies worldwide. It is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. By properly sorting and processing waste materials, recycling helps conserve resources and minimize the negative impact on the environment.
Recycling also helps to reduce the need for raw material extraction. By reusing materials, recycling helps conserve natural resources and reduces the environmental impact associated with extraction and processing. Recycling conserves energy and reduces greenhouse gas emissions by minimizing the energy-intensive processes required in the production of new materials.
The most commonly recycled plastics are Polyethylene terephthalate (PET), High-density Polyethylene (HDPE), and Polypropylene (PP). These plastics are often single-use plastics, such as plastic bottles, containers, and food packaging. However, not all plastics can be easily recycled, and the recyclability of certain plastics depends on the location and the facilities and initiatives in place.
Recycling is just one part of the solution to the plastic waste problem. While recycling technology and processes are constantly improving, our increasing reliance on plastic means that plastic pollution continues to get worse. To fully address the issue, we need to reduce our consumption, recover and repurpose plastic materials, and prioritize reusing and refilling over recycling.

Recycling is not always effective, with low rates in countries like the US
While recycling plastic is a good idea, it is not always effective, with low rates in countries like the US. Plastic recycling is the process of taking used or discarded plastic and processing it into new materials and products. The goals of this process are to help conserve natural resources, prevent pollution through excessive plastic manufacturing, and reduce the amount of plastic waste that ends up in landfills or the environment and oceans.
Recycling plastic helps keep it out of streets, parks, and oceans, and also changes how we see plastic – less as rubbish and more as something useful. Recycling can help limit the impact of plastic use on the environment and increase the availability of recycled plastic, allowing more businesses to incorporate it into their products and empowering consumers to make more sustainable choices. Recycling also reduces the need for new plastic made from raw materials, saving energy and carbon in the process. It takes 75% less energy to make a plastic bottle using recycled plastic compared to new plastic.
However, recycling is not always effective, and there is a long way to go before plastic recycling is a true solution to the plastic waste problem. Our ever-increasing reliance on plastic means that plastic pollution continues to get worse, as the demand for new plastics far outstrips the amount that ends up in the recycling bin. Recycling rates for plastic are low compared to other materials, with paper recycled at a rate of 66% compared to plastic at just 5-6% in the US. While some types of plastic containers have higher recycling rates, such as PET bottles and jars at 29.1% and HDPE natural bottles at 29.3% in 2018, the overall amount of recycled plastics is relatively small.
The ineffectiveness of plastic recycling can be attributed to several factors. Firstly, plastic comes in various forms, and not all plastics can be easily recycled. Thermoplastics, which are flexible and can be melted and reformed, are typically recycled, while thermosets, which are rigid and cannot be easily melted, have traditionally not been recycled, although technological advancements have made it possible. However, most recycling facilities do not recycle thermosets, resulting in low recycling rates for this type of plastic.
Another factor contributing to the low recycling rates is the variation in recycling practices across different locations. The types of plastic that can be actively recycled depend on the facilities and initiatives in place at a local level. For example, recycling practices in the UK vary depending on the local council, and each area has its own collection system. The UK has also historically sent most of its recycled plastic packaging overseas to countries like China, which has resulted in concerns about the responsible handling of recycling and the risk of dumping. While regulations are in place to prevent illegal shipments of waste, there have been cases of rogue traders committing this crime or recycling not being sorted to a good enough quality.
