Waste Valorization and Landfill Diversion

Te mosty direct benefit of bioenergie is te conversion of organic waste into useful energiy. Globally, landfills are a major source of methane - a greenhousie gas more potent than carbon dioxide. By diverting food waste, yard distrimings, andare agricultural residues tano anaerobic digesters or gasifiers, methane emissions are captured and converted into biogas or electricity. For example, thee Europeun estimates thath biowaste could up up 10% of the eur 's nemocampable energie exploited. For exaste.
