Municipal solid waste (MSW) from single-use plastic is normally landfilled and produces methane emissions. Energy conversion using MSW plastic requires a reduction in particle size, but this chopping creates microplastics in the process effluent, contaminating water sources and posing environmental and health challenges. Currently only 9% of plastic waste is recycled, so other methods for size reduction and cleaning are needed to reduce microplastics as more plastic waste is recycled.
