A biogas plant can be a source of waste-heat flows with different thermal parameters. Application of such flows in local, low-temperature district-heating networks is a very attractive option for highly efficient, energetically and economically, co-generation systems applying biogas as the primary energy source.
Highly effective methods of biological and chemical wastewater treatment applied in Poland resulted in an increased amount of generated sewage sludge, which pose serious problem related to its utilization. The purpose of this studies was to determine the impact of the thermal disintegration process (in low temperatures < 100°C) on the biodegradation of excess sludge, and then on the methane fermentation...
Fossil fuels have to be subsidized by renewable sources of energy, not to generate greenhouse gas emissions (GHG). The EU has a real commitment to struggling against greenhouse gas emissions. At first all over the world, implemented emission market, which values the price of emission and their mitigation effects.
