Biogas in Cuba

[Fledermaus]

HAVANA TIMES, July 11 (IPS) - Some 700 biogas plants operate on state farms and in the private farm sector in Cuba, where this technology is being produced to conserve energy and protect the environment.

Biogas is a mixture of methane and carbon dioxide, with small proportions of hydrogen, nitrogen, oxygen and sulfide of hydrogen. The gas is obtained from decomposition in an anaerobic (oxygen free) environment of organic waste, such as animal manure or vegetable waste. It is being used for lighting and cooking, reported the local media.

Besides, the energy produced also has the advantage of releasing few polluting agents. At the same time a by-product is a biodegradable organic fertilizer.

Its use in Cuba is essential in the effort to maximize the development of renewable energy resources and to reduce the consumption of traditional ones, indicated sources from the Ministry of Agriculture.
