An assessment of the French municipal solid waste (MSW) mechanical-biological treatment (MBT) unit of Mende was performed in terms of mass reduction, biogas emissions reduction and biostability of the biologically treated waste. The MBT unit consists of mechanical sorting operations, an aerobic rotating bioreactor, forced-aeration process in open-air tunnels (stabilization), ripening platforms and a sanitary landfill site for waste disposal in separated cells. On the overall plant, results showed a dry matter reduction of 18.9% and an oxidative organic matter reduction of 39.0%. A 46.2% biogas production decrease could also be observed. Concerning the biotreatment steps, high reductions were observed: 88.1% decrease of biogas potential and 57.7% decrease of oxidative organic matter content. Nevertheless, the usually considered stabilization indices (biogas potential, respirometric index) remained higher than recommended by the German or Austrian regulation for landfilling. Mass balance performed on each step of the treatment line showed that several stages needed improvement (especially mechanical sorting operations) as several waste fractions containing potentially biodegradable matter were landfilled with very few or no biological treatment.
对芒德的法国城市固体废物（MSW）机械-生物处理（MBT）单元进行了评估，评估内容包括质量减少、沼气排放减少和生物处理废物的生物稳定性。MBT 单元包括机械分拣操作、好氧旋转生物反应器、露天隧道强制曝气过程（稳定化）、陈化平台和用于废物在单独单元中处置的卫生填埋场。在整个工厂中，结果表明干物质减少了 18.9%，氧化有机物减少了 39.0%。还可以观察到沼气产量减少了 46.2%。就生物处理步骤而言，观察到了很高的减少率：沼气潜力减少了 88.1%，氧化有机物含量减少了 57.7%。然而，通常认为的稳定化指数（沼气潜力、呼吸计量指数）仍然高于德国或奥地利法规规定的填埋标准。在处理线的每个步骤上进行的质量平衡表明，几个阶段需要改进（特别是机械分拣操作），因为含有潜在可生物降解物质的几个废物部分未经生物处理或很少进行生物处理就被填埋。
