Recycling has been promoted by the plastics sector as a vital remedy for the growing issue of plastic waste. However, a study discovered that recycling may be manufacturing enormous volumes of microplastics on its own.
An worldwide group of specialists gathered waste water from a state-of-the-art recycling facility in an unidentified location in the United Kingdom. According to the Guardian, they found that 13% of all processed plastic was released into the water as microplastics.
The factory may be generating up to 75 billion plastic particles per cubic metre of effluent, according to their estimates.
The study’s principal investigator, Erina Brown, said that she was “extremely shocked.” It was carried out at Glasgow’s University of Strathclyde.
It’s unsettling because recycling was created to lessen the issue and safeguard the environment. We are seriously creating a problem here, she told the Guardian.
The microplastic concentrations in the water reduced from 13% to 6% of the processed plastic, according to the researchers’ analysis of the water before and after the facility installed a water filtering system.
A plant with a filter is assumed in the estimate of 75 billion particles per cubic metre. More than 80% of the particles, or less than 10 microns, or around the size of a human red blood cell, were smaller than five microns, according to Brown.

According to the data, there was also a high concentration of microplastics in the area around the recycling facility, with 61% of the particles being less than 10 millimetres in size. Particulates smaller than 10 mm have been linked to human sickness.
The facility was deemed by Brown to be a “best case scenario” since efforts were made to include water purification, something that many other recycling businesses might not have done. The study found that the recycling facility’s annual microplastic emissions ranged from 2,933 metric tonnes before the filtration technology was put in to 1,366 metric tonnes thereafter.
“More than 90 per cent of the particles we found were under 10 microns and 80 per cent were under 5 microns,” said Brown.
“These are digestible by so many different organisms and found to be ingested by humans,” she added.
Only around 9 per cent of the 370 million metric tonnes of plastic generated globally is recycled.
Defining microplastics
As the name implies, microplastics are tiny pieces of plastic. They are officially classified as polymers that are less than five millimetres (0.2 inches) in diameter, which is smaller than a typical pearl used in jewellery. National Geographic divides microplastics into two categories: primary and secondary.
