Résumé

Mechanical and biological pre-treatment (MBT) of residual Municipal Solid Waste (MSW) is considered as a promising technical option prior to landfilling. The aim of MBT is to control the biological landfill activity to minimize biogas and leachate production. Laboratory-scale bioreactors were set up to study the behaviour of untreated and pre-treated residues. The bioreactors were designed to simulate the anaerobic condition of sanitary landfill. Initial water addition has been performed to ensure optimal condition of biological degradation. The incubation time was 400 days to achieve the biodegradation. Experiments have been carried out with untreated or treated waste collected from a mechanical-aerobic biological treatment plant located in middle south of France. Chemical and biological analyses have been performed to characterise the waste samples before and after the incubation. Results showed that a residual anaerobic activity does exist for the pre-treated waste when incubated in optimal moisture condition: biogas production does still exist even after a long period of aerobic hot fermentation and maturation.
