PET (or PETE) is the most widely recycled plastic globally
Polyethylene terephthalate, commonly known as PET or PETE, is the most widely recycled plastic globally. PET is a lightweight, durable, and inexpensive plastic that can be easily moulded into various products, making it a popular choice for many industries. However, its non-biodegradability has led to a significant environmental impact, with plastic waste accumulating in landfills, oceans, and other natural spaces.
PET plastic is commonly used for beverage bottles, food packaging, and other consumer items. Its recycling process involves transforming it into flakes, which can then be spun into yarn for textiles or reused for the same purpose. Recycling PET reduces the environmental impact by lowering energy consumption and limiting greenhouse gas emissions.
The recycling of PET can be done through mechanical or chemical processes. Mechanical recycling involves washing, grinding, and melting the plastic, while chemical recycling breaks down the plastic into monomers to create new polymers. Chemical recycling has been found to be more efficient than other methods, leading to the creation of valuable products such as dyes, biodegradable polyesters, and drug carriers.
Despite the recyclability of PET, some countries struggle with low recycling rates due to financial and technical constraints. Additionally, the contamination of plastics and the quality of feed polymers pose challenges to the reuse of recycled materials. However, organisations like Plastics for Change are making significant progress by using post-consumer recycled plastic to create new products, such as shampoo bottles and cosmetic caps.
Overall, PET is the most widely recycled plastic globally due to its prevalence in consumer products and the feasibility of its recycling process. Efforts to improve recycling technologies and infrastructure are ongoing, aiming to reduce plastic waste and mitigate its environmental impact.

HDPE is one of the easiest plastic polymers to recycle
High-density polyethylene (HDPE) is one of the easiest plastic polymers to recycle. It is accepted at most recycling centres worldwide and can be recycled in all its forms, including bottles, bags, tanks, films, offcuts, and sheets. HDPE is a flexible plastic polymer made from petroleum and is one of the most commonly used materials in manufacturing today.
The process of recycling HDPE involves several steps. Firstly, clean and contaminated HDPE products are sorted, and all other plastic types and materials are removed for processing elsewhere. The HDPE is then thoroughly cleaned to ensure high-quality material. It is then separated once more to ensure no other polymers are present. Near-infrared radiation (NIR) techniques are often used in this step to identify and separate any non-HDPE plastics.
After sorting and cleaning, the HDPE is shredded and melted down to refine the polymer. It is then cooled and formed into pellets, which can be sold to plastics manufacturers. These pellets are used in manufacturing processes to create a range of new products, such as bottles, pens, plastic lumber, picnic tables, toys, piping, decking, and fencing. Recycling companies often sell their HDPE products to specialist recycling companies, who then sell high-quality recycled products to plastics manufacturers.
HDPE is important to recycle because it is non-biodegradable and can take hundreds of years to break down. If not recycled, HDPE can end up in landfills, where it can leach chemicals into the ground, air, and water, contributing to pollution and emissions. By recycling HDPE, we can conserve resources, water, time, energy, and reduce emissions. While HDPE is one of the easier plastics to recycle, it is important to note that the overall recycling rates for HDPE bottles are relatively low, at around 30% in the US and 28% in the UK.

LDPE is flexible, odourless, and can be recycled sometimes
LDPE, or low-density polyethylene, is a type of plastic that is flexible, odourless, and can be recycled sometimes. It is a thermoplastic polymer commonly found in items like plastic cling wrap, grocery bags, and juice containers. LDPE is thinner than its high-density counterpart (HDPE) but is sometimes used for similar purposes, like in warehouses as bubble wrap or for wrapping pallets. It is also used in cable and wire applications, flexible bottles and lids, and as coatings on paper and cardboard products.
LDPE is technically recyclable, but it is not always accepted by recycling programs. This is because LDPE products, especially flexible ones, tend to be contaminated by the items they package. For example, plastic bags can get tangled in recycling machinery and risk damaging the equipment. LDPE film used in agriculture also needs to be properly cleaned and sorted before it can be recycled, which can be time-consuming and costly.
Despite these challenges, LDPE can be recycled into a variety of products, such as plastic lumber, which is used for decking, outdoor furniture, and playground equipment. It can also be used to make compost bins, drainage pipes, black bin bags, and irrigation pipes. Recycling LDPE has several benefits, including reducing waste, conserving natural resources like oil and natural gas, and creating jobs in the recycling industry.
To increase the recycling rate of LDPE, consumers can properly dispose of their plastic waste by separating it from other types of waste and ensuring it is clean and free of contaminants. Additionally, purchasing products made from recycled LDPE and participating in local recycling programs can support the recycling of this plastic type.
While LDPE is recyclable, it is important to note that the most widely recycled plastic globally is PET or polyethylene terephthalate. PET is commonly found in plastic bottles, peanut butter jars, and cooking oil containers. It can be recycled into fashion items, carpets, and fleece clothing.

PP is one of the most popular plastic packaging materials, but only 1-3% is recycled in the US
Polyethylene terephthalate (PET) is the most widely recycled plastic in the world. PET plastic is mostly found in plastic bottles and is usually recycled into fashion items such as polar fleece clothes, backpacks, and carpets. The recycling process involves transforming PET into flakes, which can then be spun as a yarn. In 2011, approximately 7.5 million tons of PET were collected worldwide.
Despite PET being a relatively easy plastic to recycle, some countries, including the US, are struggling to reach decent recycling rates. In 2018, the recycling rate of PET bottles and jars was 29.1% globally, while the US recycling rate for HDPE bottles was around 30%.
PP, or polypropylene, is one of the most popular plastic packaging materials globally. However, only around 1-3% of PP is recycled in the US, with most of it ending up in landfills. This is due to the financial and technical challenges associated with PP recycling. It is a difficult and expensive process, and the recycled PP often ends up in colours unsuitable for packaging use. As a result, rPP is typically used for industrial applications such as plastic lumbers, park benches, auto parts, and speed bumps.
While PP recycling rates in the US are low, it is important to note that the recycling of specific types of plastic containers, such as PET bottles and jars, is more significant. Additionally, the US is not alone in its struggle to increase recycling rates; other countries, like China, also need to improve.

PVC is highly durable but is not accepted in normal municipal recycling collections
Polyethylene terephthalate (PET) is the most commonly recycled plastic. It is used in plastic water bottles, peanut butter jars, and cooking oil containers. These types of plastics can be recycled back into their original uses, but they can also be melted down and spun into fibres for carpets or stuffing for soft items like toys or pillows. In 2011, approximately 7.5 million tons of PET were collected worldwide.
However, not all plastics are widely recyclable. For example, polyvinyl chloride (PVC), which is commonly used in plumbing, sewage, agricultural piping, kids' toys, plastic trays, and furniture, is more difficult to recycle and is typically not accepted in normal municipal recycling collections. This is because PVC is highly durable and resistant to chemicals. While PVC is recyclable, the process can be challenging and expensive. For instance, developing adequate technologies to separate PVC materials, which can have very different properties and compositions, can be difficult. Furthermore, PVC waste can contain already-forbidden process additives, such as thermal stabilizers based on lead compounds and certain plasticizers, which can be harmful to the environment.
The recyclability of plastics depends on how they are made. Thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled, whereas thermoplastics can be re-melted and re-molded. The general rule of thumb is that plastics with lower resin codes are more likely to be easily recyclable.
Despite the challenges, there have been efforts to improve PVC recycling. For example, the VinylPlus initiative aims to develop more eco-friendly manufacturing, application, and recycling methods, minimize the impact of production on the environment, and promote the responsible use of process additives. As a result of this initiative, the amount of PVC recycled has increased significantly, from 18,000 tonnes in 2004 to an estimated 1 million tonnes by 2030.
While PVC is not accepted in normal municipal recycling collections, it can still be recycled through other means. Mechanical recycling involves removing impurities from the PVC and then grinding and melting the plastic granules. Feedstock recycling, on the other hand, converts the vinyl into other chemical components for manufacturing or other uses. Most PVC can be recycled six or seven times, giving recycled PVC products a 600-year lifespan.
