Plastic waste is a pressing environmental concern, with the vast majority of plastics disposed of in non-environmentally friendly ways, leading to polluted oceans, overfilled landfills, and ecological damage. While almost all plastic can be recycled in principle, in practice, there are several barriers that hinder this process. These include economic, environmental, and technical factors, as well as the difficulty of separating and recycling items made of multiple types of plastic or layers. Despite these challenges, advancements in recycling methods and technologies have increased the number of plastic types being collected and recycled over time, offering hope for a greener future.

Types 1 and 2 plastics are widely accepted by recyclers
Plastic waste is a key concern for environmentalists, governments, and organisations, as the majority of plastics are disposed of in non-environmentally friendly ways. This results in polluted oceans, overfilled landfills, and ecological damage. Therefore, recycling plastic is critical to improving the environment and bettering waste management solutions.
Plastics are sorted according to their resin type, either manually or using mechanised automated processes, or even by colour. The numbers attributed to plastics are the plastic resin codes, which quickly show which type of plastic a product is. The numbers range from 1 to 7, with 7 being 'other'. The general rule of thumb is, the lower the resin code, the more likely the plastic type is to be easily recyclable.
However, it is important to note that not all plastics are recyclable, and even if they are, they may not be recycled properly. For example, plastic bags should not be put into recycling bins because they can get tangled in the equipment at recycling facilities.

Types 3 to 6 are harder to recycle and may not be processed by some centres
Plastic resins are used in a variety of products, from beverage bottles to bags and sacks. While in theory, almost all plastic can be recycled, in practice, this is not always the case. The numbers on plastic products, usually found inside a small triangle, indicate the type of resin used to produce the plastic. These numbers range from 1 to 7, with 7 being 'other'.
Types 3 to 6 plastics are harder to recycle and may not be processed by some centres. This includes PVC, a soft and flexible plastic used for household products like plastic tubing, kids' toys, and plastic trays. PVC products cannot be recycled. LDPE, used for plastic bags, grocery bags, and newspaper bags, can sometimes be recycled, but often ends up in landfills as it is hard to separate and can tangle machinery. PP, used for food containers, straws, and rope, can also sometimes be recycled, but it usually ends up being black or grey, making it unsuitable for packaging. PS, used for disposable coffee cups and packing peanuts, can sometimes be recycled but requires specialized handling as it is considered a hard-to-recycle plastic.
The difficulty in recycling these plastics stems from various factors. Firstly, the design of plastic products is often not made with circularity in mind, intending for them to be used once and then discarded. The additives and colourants used in production also complicate the recycling process. Additionally, the diversity of plastic types and their varying recyclability adds to the challenge. Some plastics are not recycled because it is not economically viable, as it is cheaper to make new plastic than to reuse old material.

Type 7 plastics are the most challenging to recycle and are rarely recycled
Plastic is sorted according to its resin type, either manually or using mechanised automated processes, or even by colour. The numbers attributed to plastics are the plastic resin codes, which quickly show which type of plastic a product is. The numbers range from 1 to 7, with 7 being 'other'.
The wide range of plastics within type 7 means that the recyclability of each type varies. While some type 7 plastics are recyclable, many are not, and they cannot be recycled in your curbside recycling bin. Some common items made from type 7 plastics that cannot be recycled include Lego blocks, computer keyboards, takeaway containers, eyewear, CDs, plastic housing for electrical objects, and plastic used for 3D printing.
The difficulty in recycling type 7 plastics lies in the fact that they are a diverse group with many different characteristics. This includes recyclable, non-recyclable, mixed plastics, and biodegradable plastics. Additionally, the innovation and development of plastics over the years have made this group even more extensive and challenging to categorise.
Overall, while some specialist recyclers may be able to recycle certain type 7 plastics, they remain the most challenging to recycle due to their diverse and extensive nature.

PET plastic is the most widely recycled plastic globally
Plastic waste is a major environmental concern, with the majority of plastics disposed of in non-environmentally friendly ways. This has resulted in polluted oceans, overfilled landfills, and ecological damage. Recycling is critical to improving the environment and enhancing waste management solutions.
Polyethylene terephthalate (PET) is one of the most commonly used plastics worldwide. It is an inexpensive, lightweight, and durable material that can be easily moulded into a variety of products. PET is most commonly used for single-use packaging materials, such as disposable consumer items and beverage bottles. It is also used for packaging, clothing, and carpeting. PET is meant for single-use applications, as repeated use increases the risk of bacterial growth and the leaching of harmful chemicals.
Despite the challenges posed by the proliferation of PET plastic waste, it is the most widely recycled plastic globally. PET is relatively easy to recycle, and countries like India, Europe, and South Korea have achieved recycling rates of over 50%. Brazil, for example, recycled 55% of its PET packaging in 2019, amounting to the reuse of 311,000 tons. PET can be recycled into fashion items such as polar fleece clothing, backpacks, and carpets. It can also be recycled into PET bottles, as the plastic can be reformed into the same shape. Additionally, PET bottles can be used as construction materials in third-world countries.
While PET is the most widely recycled plastic, other plastics can also be recycled. HDPE, for instance, is one of the easiest plastic polymers to recycle and is accepted at most recycling centres worldwide. Recycled PP, however, often ends up being black or grey, making it unsuitable for packaging use, and is instead used for industrial applications. While recycling rates have been increasing, plastic recycling still has a long way to go to match the levels of reuse achieved by materials like aluminium and glass.

HDPE is one of the easiest plastic polymers to recycle
Plastic waste is a significant environmental concern, with the vast majority of plastics being disposed of in non-environmentally friendly ways. This has led to polluted oceans, overfilled landfills, and ecological damage. As a result, plastic recycling is critical to improving waste management solutions and the environment.
High-density polyethylene (HDPE) is one of the easiest plastic polymers to recycle. It is a strong, heavy, and fully recyclable plastic. HDPE is accepted at most recycling centers worldwide. It is also one of the most commonly used plastics, so its recyclability is crucial. HDPE has a strong internal structure, which means there is a low risk of leaching toxins into the foods or liquids it contains. This makes it one of the safest and most eco-friendly plastics available.
The process of recycling HDPE involves several steps. First, the waste is collected and transported to a recycling center. Then, the clean and contaminated HDPE products are sorted, and any other materials are removed. The HDPE is then cleaned rigorously to ensure high-quality material. It is then separated to ensure no other polymers are present. Near-infrared radiation (NIR) techniques are used to identify non-HDPE plastic, and different types of HDPE are separated. The HDPE is then shredded and melted down to refine the polymer. It is then cooled and formed into pellets, which can be used to create new products.
HDPE can be recycled into new pipes, crates, film, plastic lumber, and even recycling bins. It is often downcycled into products like plastic lumber, tables, roadside curbs, and benches. This process of downcycling involves reusing materials for lower-value products. HDPE is also used in building materials such as piping, decking, and plastic fencing.
Overall, HDPE is one of the most accessible plastic polymers to recycle, and its recyclability plays a vital role in improving the environment and promoting eco-friendly alternatives.
