Abstract: Anaerobic deterioration of biodegradable wastes in landfill sites is an important source ofgreenhouse gases. Of the estimated UK total of 2330 kt methane emitted in 2008, 966 kt(equivalent to 24 Mt of carbon dioxide) came from landfill, compared with 876 kt from livestockagriculture, the next largest source. Increasing the amount of methane that is recovered andused as fuel is an important method of reducing emissions. In 2008 Cranfield University was asked by the Environment Agency (EA) to run a 12 day course to train 12 EA officers, based on the knowledge of a retired EA industry expert. At the end of thecourse, the students split into two groups, each of which undertook 12 site visits. These 24sites were subsequently assessed by the EA, who estimated that the additional measuresrecommended had collected an additional 7,600 m3/hr of landfill gas. A further 12 officers havenow received the advanced training, and another 70 have attended a foundation course inwhich they learn how to audit and assess landfill gas controls on sites. The additional collection of methane resulting from the first set of visits is equivalent to453 kt CO2e/year. Extrapolating from this by making conservative assumptions about possiblediminishing returns, the savings to the end of 2010 from the two groups (the retrospectivebrainprint) are about 1,330 kt CO2e with a 95% confidence range of 1,091-1,570 kt CO2e. Usingthe same assumptions, if both groups continue working for a further three years, the savingsover the five year period (the prospective brainprint) will be 5,380 kt CO2e with a 95%confidence range of 3,695-7,309 kt CO2e.
