Abstract

The proper disposal of post-consumer waste is one of the most urgent problems that must be addressed in many countries throughout the world. In the United States, about 85% of the municipal solid waste (MSW) was disposed by burial in landfills. The number of solid waste composting plants in operating has increased from 8 in 1990 to 18 n 1991. In this paper, we present a method for studying the degradation kinetics of plastics using a simulated in-laboratory composting test. Also, the authors preliminary results on the biological degradability of cellulose acetate, CA (degree of subsitution, d.s., 1.7 and 2.5), as well as poly(95% [L]-lactide), PLA, using this in-laboratory test methodology.
