Recycling has been promoted by the plastics sector as a vital remedy for the growing issue of plastic waste. But according to recent studies, recycling may be producing a significant number of microplastics. A worldwide group of specialists gathered wastewater 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.
“I was incredibly shocked,” said Erina Brown, the lead researcher of the study, conducted at the University of Strathclyde in Glasgow. “It’s scary because recycling has been designed in order to reduce the problem and to protect the environment. This is a huge problem we’re creating,” 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. 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.
Microplastics are defined as any plastic particle smaller than 5 mm
Microplastics, which are defined as any plastic particle smaller than 5 mm, have been found all over the world, even inside human organs and freshly fallen Antarctica snow. They could be harmful to both plants and animals. 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. Microplastics are tiny plastic flecks, as the name implies. Their diameter is officially defined as being less than five millimetres (0.2 inches) less than that of a typical pearl used in jewellery. National Geographic divides microplastics into two categories: primary and secondary. Primary microplastics include fibres that are shed from clothing and other materials, such as fishing nets. Particles known as secondary microplastics develop during the breakdown of larger plastic items like water bottles. Exposure to external factors, such as sunlight and ocean waves, causes this dissolution.
