These are strict anaerobic bacteria and mainly occur in muddy areas and also in stomach of cattle, where cellulose is fermented by microbes. These are responsible for methane gas (CH4 ) formation in bio-gas plants, because they have capacity to produce CH4 from CO2 or formic acid (HCOOH).
GreenCape has observed an increasing amount of interest and requests for information and market intelligence on the production of biogas from solid waste. This biogas document has been developed to assist those considering installing a biogas system. It outlines the factors affecting the financial feasibility of such an endeavour and forms part of GreenCape’s sector development efforts to assist in the uptake of biogas technology and the development of the industry in the Western Cape and in the rest of South Africa.
The landscape of renewable energy finance has evolved rapidly. Since 2012, renewable power capacity installations have exceeded non-renewables by a rising margin, representing about 60% of all new power-generating capacity added worldwide in 2016 (IRENA, 2017a). Investment reached a comparable milestone in 2015, when renewable power technologies for the first time attracted more finance than non-renewable power technologies (Buchner et al., 2017), a trend that has continued subsequently.
