Landfill Gas Utilization System
Benefiting our Community and the Environment
Fundy Region Solid Waste has implemented an innovative Landfill Gas Management and Utilization System. This system produces green energy, while eliminating odours, reducing greenhouse gases and decreasing the environmental impact on air quality.
Landfill gas is compromised of 50% methane gas which is a potent greenhouse gas.
A series of gas collection wells and pipes are constructed in each capped landfill cell. The landfill gas is piped out of the landfill into the gas cooling system and then into the generating unit to produce and transmit electricity.

How it works |
|
Blower UnitThe Blower Unit maintains the consistent flow of landfill gas from the gas wells into the Flare. |
|
|
|
FlareThe Flare is the back-up unit for the Generator during shut down and will destroy landfill gas for odour control and greenhouse gas reduction. |
Cooling UnitThe Cooling Unit cools, dehumidifies and compresses the landfill gas to prepare it for use by the generator. |
|
|
|
Landfill Gas GeneratorThe Generator uses landfill gas as a fuel to drive a 20 cylinder internal combustion engine to generate 1 MW of electricity: enough to power approximately 800 homes. |
TransformerThe 600V Transformer converts the voltage of the green electricity to the voltage usable by the power lines. The electricity is fed directly into the Saint John Energy grid. |

undy Region Solid Waste Commission has implemented a Landfill Gas Management System at Crane Mountain Landfill. This system produces green energy while eliminating odours, reducing greenhouse gases, and decreasing the environmental impact on air quality.
When organics like food, yard waste, and paper products are placed in the garbage and buried in the landfill, over time they will biodegrade anaerobically (without oxygen). This creates landfill gas, which is comprised of several different gases.
By far the most significant of these is a greenhouse gas called methane. Methane is 21 times more potent than carbon dioxide. While methane gas is odourless, as it discharges from the garbage, it brings small amounts of other odour-causing compounds.
A series of Gas Collection Wells and Lines are constructed in each cell. Then each cell is then capped.
