oa Civil Engineering = Siviele Ingenieurswese - Landfill gas recovery, green energy, and the clean development mechanism
The environmental advantages of the extraction, destruction and possible utilisation of landfill gas (LFG) have been well documented, and South Africa is in an advantageous position in terms of the Clean Development Mechanism (CDM) provisions of the Kyoto Protocol, an initiative of the United Nations Framework Convention on Climate Change (UNFCCC). In addition to the environmental benefits associated with a significant reduction of landfill emissions, the sale of such quantifiable units, called "Emissions Reductions" (ERs), can provide a sustainable source of funding that can be channelled back into waste management initiatives. The potential use of the gas as a renewable energy source for power generation, coupled with the revenue derived from the sale of the electricity is an added bonus.
