Mechanical biological treatment of municipal waste: impact of retention time of the Rotary Drum ReactorThis entry was posted

Mechanical Biological Treatment (MBT) is a proven technology for the treatment of municipal solid waste (MSW). The number of MBT plants is increasing significantly in recent years. In a significant number of these plants, the three major elements are a Rotary Drum Reactor (RDR) for preparation of the waste, an anaerobic digestion system for organic matter degradation and energy recovery followed by a composting step for organic matter stabilisation. Although industrial feedback exists, there is a lack of scientific results at industrial scale. For that reason, Veolia Environnement Recherche et Innovation (VERI), with the support of the Agence de l’Environnement et de la Maîtrise de l’Energie (ADEME), carried out a research project to evaluate the performance of an MBT of residual municipal solid waste (rMSW) including a 24-m RDR from the VEOLIA-operated industrial site of Champagne sur Oise, the VERI semiindustrial (21m3) dry anaerobic digester at Graincourt les Havrincourt and the VERI pilot-scale (160L) composting reactors at Limay. The objective of the project was to evaluate the impact of the retention time of the RDR, which varied between 1.5 and 4 days, on the performance of the biogas production in the mesophilic anaerobic digestion, the compostability of the digestate and the agronomic value of the final product.
