Abstract: | This new century addresses several environmental challenges among which distribution of drinking water, global warming and availability of novel renewable energy sources to substitute for fossil fuels are of utmost importance. The last two concerns are closely related because the major part of carbon dioxide (CO(2)), considered as the main cause of the greenhouse effect, is widely produced from fossil fuel combustion. Renewable energy sources fully balanced in CO(2) are therefore of special interest, especially the issue of biological production from organic wastes. Among the possibilities of bioenergy production from wastes, two approaches are particularly interesting: The first one is relatively old and related to the production of biomethane by anaerobic digestion while the second one, more recent and innovative, relies on biohydrogen production by microbial ecosystems. |
