PET plastic is widely recycled, but some countries are struggling to improve their rates
PET plastic, or polyethylene terephthalate, is widely recycled and has been since the technology was developed in the 1970s. The process is simple: removing labels, shredding, and washing the plastic, which can then be used as a raw material for manufacturing new products. The plastic is also lightweight, which reduces the emissions associated with transport. However, some countries are struggling to improve their recycling rates.
In 2018, the recycling rate of PET plastic bottles in Norway was 97%, the highest in the world. This is due to Norway's efficient deposit-return scheme, where consumers pay an additional fee on plastic bottles at the point of purchase, which is reimbursed when they return the bottles to reverse vending machines. Other countries, like the United States, have much lower recycling rates for PET plastic. In 2018, the US only recycled 29% of its PET bottles.
The US recycling rate is low compared to Norway's, but it is improving. The total amount of recycled plastics in the US was 8.7% in 2018, with 3 million tons recycled. While this is a relatively small amount, the recycling of specific types of plastic containers is more significant. The rate for PET bottles was 29.1%, and for HDPE natural bottles was 29.3%.
The PET bottle recycling industry is dependent on the number of bottles available for recycling. The number of bottles collected for recycling in Europe has grown significantly over the last decade. Several EU member states have achieved high PET bottle recycling rates, with Lithuania reaching 92% in 2019.

It is easy to sort PET plastic, and it can be economically recycled
PET, or polyethylene terephthalate, is a type of plastic that is widely used for beverage packaging. It is strong, colourless, and lightweight, making it a popular choice for drink bottles. The process of recycling PET plastic involves several steps, including collection, filtering, sorting, rinsing, and recycling.
One of the key advantages of PET plastic is that it is easy to sort. Plastic drinking bottles made of PET are widely available and come in distinct colours, such as blue, green, and clear. This makes it simple to separate them by colour for recycling. The PET bottle recycling industry is well-established and efficient, relying solely on the number of bottles available for recycling.
The sorting process is crucial, as contaminating the PET recycling process with other types of plastic can reduce the quality of the recycled material. Therefore, it is essential to separate PET plastic from other non-recyclable plastics and sort it into distinct groups. This can be done using the resin identification code on each plastic item.
PET plastic is also economically recycled. It can be recycled through traditional methods that are tried and tested. The recycled PET (rPET) can be turned into new packaging, such as bottles, and the process of recycling reduces greenhouse gas and carbon emissions, requiring less energy to produce new products. Additionally, the lightweight nature of PET plastic reduces emissions associated with transport, making it even more economical.
Overall, PET plastic is easy to sort, widely recycled, and economically viable, making it a valuable resource for the packaging industry.

PET plastic is lightweight, so it is easy to transport
PET plastic, or polyethylene terephthalate, is a lightweight material. This makes it easy to transport, which is a key part of the recycling process. PET bottles are often compressed into small bales, reducing the space they take up and making them easier to handle during transportation. This compression also reduces emissions associated with transport, as more material can be transported at once.
The lightweight nature of PET plastic is a significant advantage in the recycling process. Its low weight means that it can be easily moved and handled during sorting, collection, and transportation to recycling centres. This ease of transport is beneficial for both the efficiency and cost-effectiveness of the recycling process.
The recycling process for PET plastic typically begins with collection and sorting. Curbside collection or deposit refund systems are commonly used to gather PET bottles for recycling. The lightweight nature of PET makes it easier to collect and transport large quantities of these bottles, reducing the overall effort and cost of the collection process.
Once collected, PET bottles are sorted according to colour, enabling them to be recycled separately. The lightweight property of PET plastic facilitates the sorting process, making it easier for machines or individuals to handle and separate the bottles efficiently.
After sorting, the PET bottles are transported to a processing centre. Here, they are processed and transformed into recycled PET (rPET), ready to be reused. The lightweight characteristic of PET plastic reduces the complexity and cost of transporting the bottles to the processing centre, contributing to the overall efficiency of the recycling process.
In conclusion, the lightweight nature of PET plastic significantly contributes to its ease of recyclability. It reduces the effort, cost, and emissions associated with transportation during the various stages of the recycling process. This makes PET plastic a favourable material for recycling and contributes to its widespread use in the food and beverage industry.

The recycling process includes removing labels, shredding, and washing
PET plastic, or polyethylene terephthalate, is a type of plastic that is widely used for food packaging and beverage bottles. It is easily recyclable through traditional methods, and the recycling process includes removing labels, shredding, and washing.
Firstly, removing labels from PET plastic bottles is not always necessary, as the labels will float off and be separated during the washing process. However, some recyclers recommend removing labels, especially if they are made of PVC, as PVC degrades PET and causes additional costs for recyclers. PVC can be identified as a hard, shrinking foil, while PE foil will float and can be left on the bottle.
Next, the shredding process involves cutting or grinding the PET plastic into small pieces. This can be done using a plastic shredder or grinder, which typically works through a mechanism of counter-rotating wheels with grooved teeth to grab and tear the plastic.
Finally, the washing process involves cleaning and sanitizing the PET plastic. This includes rinsing out any residue or liquids originally stored in the bottle, washing the bottle in hot, soapy water, and then sanitizing it with a mild bleach solution (1 teaspoon of bleach per quart of water). Soaking the bottle in the bleach solution is especially important if the plastic smells musty or shows signs of mildew or mold. It is also recommended to let the bottle dry completely before reusing it to prevent bacterial growth.
Overall, the recycling process for PET plastic is straightforward and accessible, making it easy to recycle this type of plastic.
