Solid waste disposal,risk and management—Effect of microplastics on methane production from organic components of municipal solid waste(MSW)
The effects of microplastic exposure levels of different chemical components(polyethylene and polypropylene)and concentrations(20,40,80/g polyethylene)on the methane(CH4)production through organic fractions of solid waste decomposition were investigated in batch series of simulated bioreactors.Results show that microplastic exposure significantly(P＜0.01)affected the total organic carbon content in the degradation process,which varied from-18.03％to 22.65％;microplastics exposure significantly(P＜0.01)promoted the accumulation of acetic acid in the hydrolysis and acidification stage of the degradation process,with an average increase of 19.09％;microplastic exposure significantly(P＜0.01)inhibited the production and accumulation of CH4,and the cumulative yield decreased by 21.38％to 46.56％;the exposure of different chemical components of microplastics significantly(P＜0.01)affected the CH4 production,and the concentration of polyethylene microplastics had no significant effect on the CH4 production.
