What You'll Learn
PET is the most widely recycled plastic
PET (polyethylene terephthalate) is a type of plastic that is clear, durable, shatterproof, light, and versatile. It is widely used for beverage bottles, food packaging, medical devices, and personal protective equipment (PPE). PET is unique among plastics because it is almost infinitely recyclable. This means that it can be recycled and made into new products repeatedly, reducing the need for fresh PET and lowering emissions. Recycled PET (rPET) has a significantly lower carbon footprint than virgin PET, with a 79% reduction in carbon dioxide emissions.
The recyclability of PET makes it less likely to end up in landfills. In Europe, about 58% of PET bottles are recycled, and several EU member states, such as Lithuania, have achieved PET bottle collection and recycling rates above 80%. In the United States, PET is also the most recycled plastic. The success of collection schemes, such as deposit refund systems, has been crucial in increasing the recycling of PET. These schemes encourage consumers to return bottles to retailers or recycling centres in exchange for a refund.
The PET recycling process typically involves sorting, cleaning, and transforming the plastic into rPET flakes or pellets. These flakes or pellets can then be used to create new products, including new PET bottles, closing the loop on the recycling process. The high recyclability of PET is advantageous because it reduces the environmental impact of plastic production. Using rPET instead of new plastic results in a 79% reduction in energy consumption and a 67% decrease in greenhouse gas emissions.
However, one challenge in the PET recycling process is the separation of coloured PET bottles. Unlike clear PET, coloured varieties are only useful to the specific manufacturer that uses that particular colour. This limits the market for coloured PET and can impact the financial viability of recycling these materials. Nevertheless, PET remains a highly valuable and sought-after material for recycling due to its versatility and recyclability.

rPET has a lower carbon footprint than virgin PET
Recycled PET (rPET) is a highly sought-after material. Using rPET instead of new plastic reduces environmental impact. When used to make new bottles, total energy consumption is reduced by 79% and greenhouse gas (GHG) emissions are limited by 67%. rPET has a carbon footprint that is 79% lower than its virgin PET counterpart. Virgin PET has a carbon footprint of 2.5kg CO2 per kg, while rPET has a footprint of 0.45kg CO2 per kg.
RPET is made from recycled PET (polyethylene terephthalate) plastic, which is used to make packaging such as plastic bottles and food containers. After the original PET containers are used by consumers, they are returned via a recycling program to a facility that sorts, cleans, and transforms the plastic into rPET flakes or pellets. The rPET flakes/pellets can then be reused to make new products, such as fiber for clothing and carpets or plastic for food and beverage containers.
The process of recycling PET bottles is straightforward. It involves removing the labels, shredding the PET waste, and washing the shredded plastic. The washed plastic is then melted and turned into spherical, crystalline-PET-pellets for the production of new PET bottles. This recycled PET is then sent to manufacturers for use in the packaging industry.
The success of collection schemes is central to getting the most out of this unique material. Deposit schemes are a great way of helping consumers understand the value of PET and that not all plastic packaging is the same. After being sorted by consumers, PET bottles are collected and taken to a recycling plant along with other recyclable materials. Collection is key as the industry has more recycling capacity than is being used.
RPET bottles produce lower transport emissions than reusable glass bottles as they are much lighter. Glass is also significantly heavier than plastic, weighing up to 10 times more and resulting in a much larger carbon footprint for transport.

PET is safe for food packaging
PET plastic is a safe, lightweight, and recyclable material that is ideal for food and beverage packaging. It is resistant to chemicals, shatterproof, and customisable, helping to meet the specific needs of manufacturers. PET is also inert and does not give off contaminants into the environment, which, combined with its recyclability, means it has virtually no direct impact on the planet. PET is approved by the FDA (Food and Drug Administration) for use in food and beverage packaging. It is considered safe for use with food because it is non-toxic and does not contain any harmful chemicals that can leach into food or beverages.
PET is a popular choice for food and beverage packaging in the industry due to its durability, lightweight, and transparency. PET bottles are also a safe and convenient option for packaging beverages. They are food-grade, stable, and resistant to chemical leaching, and they can be recycled to help reduce their environmental impact. PET is also one of the most commonly recycled plastics. It can be recycled and made into a wide range of products, including new PET bottles, clothing, and carpet fibres. The majority of PET bottles are collected for recycling in the United States and other countries.
However, it is important to note that there are concerns about the potential for PET bottles to release harmful chemicals when they are disposed of. Some studies have found that recycled PET bottles may leak more potentially dangerous chemicals than bottles made of virgin or new plastic. This has raised questions about the safety of using recycled PET for food and drink packaging, as it is not guaranteed to be sufficiently free of chemicals. While PET is a safe and popular choice for food and beverage packaging, it is always important to consider the potential environmental and health impacts of any packaging material.
To address the concerns about chemical leaching, some companies are working towards increasing the collection of plastic bottles so they can be remade into new bottles. This helps to reduce the plastic footprint and ensure that bottles do not end up in places like lakes, rivers, or landfills. Efforts to improve recycling processes and encourage the use of refillable bottles can also help mitigate the potential environmental and health risks associated with PET bottles.
