Abstract
A laboratory test system is presented for measuring the aerobic biodegradability of biodegradable materials under composting conditions. The test system is based on an aquatic test and a solid state compost simulation test. Microbially produced carbon dioxid and consumed oxygen resulting from the biodegradation process is measured on-line for a series of bioreactors in parallel. In the aquatic test ultimate biodegradation is proved by conducting a carbon balance. Results of biodegradation experiments in the aquatic test and the solid state compost simulation test are presented.
