Landfills account for over two per cent of Australia’s greenhouse emissions, dominating emissions from waste and wastewater. Methane emissions are inherent to landfills because waste cannot be permanently sealed until a landfill cell is full. In this project, a microbial fuel cell (MFC) landfill cover will be developed as a means of achieving full biogas capture, from the time that waste is placed. The MFC cover system would consist of a relatively thin and deformable granular graphite layer colonised by current generating methane oxidising microorganisms, overlain by a proton exchange membrane and steel mesh as the anode layer. The MFC cover will provide the benefit of power generation as well as more complete greenhouse gas mitigation.

垃圾填埋场占澳大利亚温室气体排放量的2%以上，主要是废物和废水的排放。甲烷排放是垃圾填埋所固有的，因为在垃圾填埋单元填满之前，废物不能永久密封。在该项目中，将开发一种微生物燃料电池（MFC）填埋场覆盖物，作为从废物放置时起实现完全沼气捕获的手段。MFC覆盖系统将由相对薄且可变形的颗粒石墨层组成，该颗粒石墨层被电流产生的甲烷氧化微生物定殖，被质子交换膜和作为阳极层的钢网覆盖。MFC盖将提供发电的好处以及更全面的温室气体减排。
