Gasification of Municipal Solid Waste for Large-Scale Electricity/Heat © ClimateTechWiki and respective owners

Thermal gasification of municipal solid waste (MSW) is a chemical process that generates a gaseous, fuel-rich product. This product can then be combusted in a boiler, producing steam for power generation. Just as with combustion of MSW, thermal MSW gasification does not necessarily compete with recycling programmes, but should be considered complementary in any generically constructed MSW plan.

Geothermal Electricity Production geothermal flash steam

Inside the Earth's crust there are several reservoirs with hot water which can be used for heating buildings and/or production of electricity. The process causes relatively little CO2 emissions (from the steam), which could potentially be reinjected in the earth's crust through carbon capture and storage. Contrary to conventional geothermal power plants, present generation plants re-inject the condensated steam or hot water into the underground acquifer so that the reservoir capacity could remain intact.

Agricultural ecosystems hold large carbon reserves (IPCC, 2001a), mostly in soil organic matter.Historically, these systems have lost more than 50 Pg Carbon, but some of this carbon lost can be recovered through improved management, thereby withdrawing atmospheric CO2 (Paustian et al., 1998; Lal, 1999, 2004a).

Greening the built environment © ClimateTechWiki and respective owners

Greening the built environment is one of the most feasible and cost effective mitigation options for building sectors in rural and low density urban areas. Simple techniques, such as providing a garden and a pond, can be found in traditional houses in many countries. Taking a traditional house setting in Vietnam for example, plants in the garden provide vegetables and fruit, absorb carbon dioxide, offer shade and cool the ambient temperature.
