Researchers in China have published a review that identifies innovative biotic and abiotic recycling and upcycling methods for PET plastic.

The invention of plastics, particularly polyethylene terephthalate (PET), in the 20th century marked a significant technological milestone.

Being lightweight, flexible and highly durable, this material could be used for a whole host of applications, from single-use plastic bottles and packaging to clothing and carpets.

So popular was plastic that since the 1950s its production has ramped up. Scientists estimate that around 450 million tonnes of plastics are produced every year.

However, this large-scale production has led to large-scale plastic pollution as its durability means it is resistant to natural degradation.

While over 175 countries have signed up to a UN proposal to create a binding agreement this year to combat plastic pollution, there need to be significant strides in effective recycling strategies.

To address this issue, researchers at...
