Using fibre-catching devices as part of the laundry process can dramatically reduce the amount of microscopic particles potentially entering the marine environment, according to new research.
A study conducted at the 精品无码国产自产 compared the efficiency of six different devices, ranging from prototypes to commercially available products.
The most successful reduced the amount of fibres released into wastewater by almost 80%, suggesting there is considerable potential for them to have environmental benefits.
However, writing in Science of the Total Environment, researchers from the University鈥檚 International Marine Litter Research Unit say they will only ever be part of any solution.
A recent study at the University showed normal wear and tear when wearing clothes is just as significant a source of microplastics as release from laundering, while a report produced for Defra in May 2020 highlighted that fitting filters to washing machines could be less effective than changing fabric designs to reduce fibre loss.
As such, the current study鈥檚 authors say there is an ongoing need for scientists to collaborate with industry and policy makers to ensure improvements are made right from the design phase through to how clothes are washed.
The study was funded by the National Geographic Society and Sky Ocean Rescue. Research Fellow and National Geographic Explorer Dr Imogen Napper, a Sky Ocean Rescue Scholar and the study鈥檚 lead author, said:
鈥淔ibres from clothing are among the key sources of microplastics, and companies are inventing ways which claim to reduce the amount of fibres which enter wastewater. We wanted to see how effective they were both in catching fibres, but also stopping clothes from shedding them in the first place. Our results show there is a huge variety between the devices available, with some significantly reducing the number of fibres released.鈥
