Global discharge of microplastics from mechanical recycling of plastic
We conducted crushing tests with 13 different plastics and documented the size distribution of particles generated. We then estimated the discharge of microplastics associated with recycling and their removal in wastewater treatment plants.

Global discharge of microplastics from mechanical recycling of plastic
The global discharge of microplastics in untreated wastewater associated with the crushing of plastics during mechanical recycling in 2017 was 0.092 Mt, whereas the discharge from treated wastewater from WWTPs was only 0.004 Mt (Fig. S8). The implication is that the discharge of microplastics could be effectively reduced by reducing the amount ...
