Description

The scope of this protocol enables generation of emission offsets for landfill gas capture and combustion and/or combustion of landfill gas in an energy recovery system that displaces electricity. The installation of landfill gas capture and combustion technology can convert methane to carbon dioxide resulting in a reduction in greenhouse gas emissions. Combustion with energy recovery can further reduce emissions by displacing fossil fuel sourced energy used to generate electricity and heat.

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.

Quantification protocol for landfill gas capture and combustion. Version 2.0

Description

Anaerobic decomposition of organic waste materials in a landfill generates gases that contain approximately 60 per cent methane, a greenhouse gas (GHG). The amount of methane emitted from a... More ≫

Description

Anaerobic decomposition of organic waste materials in a landfill generates gases that contain approximately 60 per cent methane, a greenhouse gas (GHG). The amount of methane emitted from a landfill can be reduced through the installation of landfill gas capture and combustion technology to convert the methane to carbon dioxide. Combustion with energy recovery further reduces GHG emissions by displacing fossil fuel sourced energy to generate heat and electricity. This document presents the methodology for quantifying methane emission reductions which result from the use of one or both of these methods of reducing methane emissions.

Description

The report includes a comprehensive view of all major energy resources in Alberta and the pathways that are used to create basic energy commodities used in Alberta, namely, heat, electricity and transportation fuels. A broad span of consistent metrics are used to assess each resource, making it possible to understand energy availability, energy density, and the environmental impact of a wide range of energy resources and pathways in Alberta.

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.
