Biogas: From Parma Pigs’ Manure to Green Electricity

Like many countries, Italy has set an ambitious goal to foster production of renewable energy from biogas. To benefit from this forward-looking policy, a pig farmer from the region of Parma has invested in two biogas engine power plants: the liquid manure produced by his pigs ferments with corn in a big green tank to produce biogas which powers the containerised cogeneration engine power plants. While the electricity generated is fed into the public grid, the heat produced is used to keep the pigsties warm in winter.

ORC: from Waste Heat to Useful Electricity in Italy

With 'Organic Rankine Cycle' (ORC), a turbine coupled to an electrical generator transforms waste heat from gas engine exhaust into additional useful electricity. This smart principle has been implemented at a biogas power plant located in Carpaneto Piacentino in Italy. Not only methane gas has been transformed into electricity (instead of merely flaring to the atmosphere - where its environmental impact is up to 20 times worse than carbon dioxide) but also waste heat has been converted into additional 65 kW of electricity. This means energy efficiency and a better environmental footprint.
