Degradation of microplastics and the plastisphere bacteria in the acidogenic phase of simulated municipal solid waste landfilling
Researchers simulated conditions inside a municipal solid waste landfill and found that different microplastic types (PE, PS, and PLA) aged and degraded at very different rates during the acidogenic leachate phase, with distinct microbial communities forming on each plastic type. This matters because landfills are both sources and sinks for microplastics, and understanding how plastics degrade there helps predict what eventually leaches into groundwater and surrounding soil.
