Biogas is a typical "product" of urban discharges, which has a great negative environmental impact. To avoid this negative effect, it can be burnt at very high temperatures, producing smoke emissions composed of CO2. A useful alternative is to use biogas as fuel to feed co-generation plants, producing electricity. At the moment biogas is used as fuel, introducing it directly in the combustion chamber. Nevertheless the heterogeneity of the gas stresses the engine, reducing its life. The new technology should treat the biogas before putting it into the engine, reducing its heterogeneity and stabilizing it in that range of characteristics which are acceptable for the engine. Such a technology has the advantage to preserve the environment from the emission of biogas, guaranteeing, at the same time, a higher safety of discharges. In fact, biogas produced by urban discharges could create big gas pockets with a high pressure that could cause explosions. Using biogas as fuel for internal combustion engines will make discharges safer than before and at the same time it will be a useful alternative source of power. While biogas has multiple benefits at the individual family level, it also has several qualitative and quantitative benefits at the societal level.
