Thermal insulation is an important technology to reduce energy consumption in buildings by preventing heat gain/loss through the building envelope. Thermal insulation is a construction material with low thermal conductivity, often less than 0.1W/mK. These materials have no other purpose than to save energy and protect and provide comfort to occupants. Of the many forms, shapes and applications of thermal insulation, this section focuses on those that are commonly used for building envelopes– i.e., floor, walls and roof, and have potential for South-South technology transfer.

An inexpensive way to reduce greenhouse-active methane emissions from existing Municipal Solid Waste (MSW) landfills is to exploit the natural process of microbial methane oxidation through improved landfill cover design. Landfill top covers, which optimise environmental conditions for methanotrophic bacteria and enhance biotic methane consumption, are often called ‘biocovers’ and function as vast bio-filters. Biocovers are typically spread over an entire landfill area.
