Mechanical-biological treatment (MBT) processes are increasingly being adopted as a means of diverting biodegradable municipal waste (BMW) from landfill, for example to comply with the EU Landfill Directive. However, there is considerable uncertainty concerning the residual pollution potential of such wastes. This paper presents the results of laboratory experiments on two different MBT waste residues, carried out to investigate the remaining potential for the generation of greenhouse gases and the flushing of contaminants from these materials when landfilled. The potential for gas generation was found to be between 8% and 20% of that for raw MSW. Pretreatment of the waste reduced the potential for the release of organic carbon, ammoniacal nitrogen, and heavy metal contents into the leachate; and reduced the residual carbon remaining in the waste after final degradation from ∼320g/kg dry matter for raw MSW to between 183 and 195g/kg dry matter for the MBT wastes.
机械-生物处理（MBT）工艺越来越多地被采用，作为将可生物降解的城市废物（BMW）从垃圾填埋场转移的一种手段，例如为了遵守欧盟的垃圾填埋指令。然而，对于这些废物的残余污染潜力仍存在相当大的不确定性。本文介绍了在两种不同的 MBT 废物残渣上进行的实验室实验结果，这些实验旨在研究当这些废物被填埋时，产生温室气体的剩余潜力以及从这些材料中冲洗污染物的潜力。发现气体生成的潜力在 raw MSW 的 8%到 20%之间。废物的预处理降低了有机碳、氨氮和重金属含量释放到浸出液中的潜力；并减少了 raw MSW 中剩余的碳量，从约 320g/kg 干物质减少到 MBT 废物中的 183 到 195g/kg 干物质。
