Description

This protocol covers landfills or landfill cells which are at capacity, will not be accepting more waste materials and are covered. Rather than the content of these landfills or landfill cells decomposing anaerobically and producing methane, wells are drilled for the purposes of aerating the waste and recirculating leachate. Conditions are maintained to support aerobic decomposition of the waste. The resulting carbon dioxide emissions are considered as biogenic.

Description

The protocol outlines the methodology used to calculate emission reductions that result from the use of an aerobic landfill bioreactor. The protocol applies to landfills or landfill cells which are at capacity and will not be accepting more waste materials, and are covered. Rather than the content being left to decompose anaerobically and producing methane, wells are drilled to aerate the waste and recirculate leachate. The resulting carbon dioxide emissions are considered as biogenic. The protocol is written for the aerobic landfill bioreactor project developer and assumes the reader has some familiarity with or general understanding of waste management practices including aerobic composting and the operation of a landfill.

Description

A subsurface investigation at a reclaimed sanitary landfill in Edmonton (Beverly) has revealed that combustible gases entering a golf course structure are generated from decomposing garbage in the old landfill. Gases containing methane up to a maximum of 83% by volume are present in the subsurface adjacent to the structure. A ventilation system beneath the building maintains the methane concentration at less than 50% of the lower explosive limit (2.5 volume percent). The atmosphere beneath the structure is monitored continuously for combustible gases; an automatic alarm system will be activated should methane concentration exceed 50% of the explosive rate. Based on the results of this investigation, it is apparent that a large reservoir of combustible gas is present within the reclaimed landfill site. It is probable that the methane monitoring/warning system, and the ventilation system must remain operative for a period in the order of 50 years or more.
