Plasma Gasification can reduce CO2 emissions
PTDR waste-to-energy facilities also offer benefits in the reduction of the generation of greenhouse gases ("GHG") and thus potentially generate carbon credits. Carbon credits are GHG emission reductions that are created when a project reduces or avoids the emissions of GHGs, relative to what would have been emitted under a 'business as usual' scenario.
There are a number of viable GHG reduction scenarios applicable to the PTDR waste-to-energy technology:
- Reduction of CO2 and Nitrous Oxides: When plasma gasification synthesis gas is used for thermal and/or electrical energy production the amount of GHG's produced, is approximately 1/2 of that produced by the combustion of coal and/or fuel oil for an equivalent amount of energy produced.
- Avoidance of land filling materials containing organic constituents avoids the production of methane which is has a Global Warming Potential (GWP) that is 22 times that of CO2.
Carbon credits are measured in units of certified emission reductions (CERs). Each CER is equivalent to one ton of carbon dioxide reduction. Depending on the 'business as usual scenario', the waste stream(s) processed and the PTDR system type, hundreds to thousands of CERs can be generated in a given year.
