Landfill Based Rapid Anaerobic Digestion of Municipal Solid Waste

城市固体废物的快速消化有可能使易腐烂的垃圾填埋场过时。垃圾可以在填埋之前被消化，消除气味和甲烷的排放。在欧洲一些地区，预消化目前是在高度机械化的容器内消化器中进行的。我们实验室的实验表明，在静态床上也能达到类似的消化速度。这项技术可以可行地规模化，以消化澳大利亚城市产生的大小垃圾流。该项目将在昆士兰州伊普斯威奇附近的Thiess Swanbank垃圾填埋场进行一系列测试单元试验，扩大这项技术的规模。

The rapid digestion of municipal solid waste has the potential to make putrescible landfills obsolete. Waste can be digested prior to landfilling, eliminating odour and the emission of methane. Pre-digestion is currently performed in highly mechanised in-vessel digesters in some European locations. Demonstations in our laboratory have shown similar digestion rates can be achieved in static beds. This technology can be feasibly scaled to digest waste streams of the size produced by Australian cities. The project will scale up this technology in a series of test cell trials at the Thiess Swanbank landfill near Ipswich, Queensland.
