Heat and electrical energy from waste and biomass to reduce greenhouse gas emissions

The remaining energy in the waste (construction waste, waste wood, paper and cardboard) can be converted into heat by combustion, some of which can be used as work. Reduction is not the avoidance of greenhouse gas emissions, but it is a significant relief. In the combined heat and power plant Munich-North in Germany, 800 thousand tons of hard coal but also 650 thousand tons of residual waste are incinerated, which produces 900 megawatts of heat and 411 megawatts of electricity. By comparison, in Bolzano/South Tyrol in Italy, where 52% of the region's waste is recycled, 59 megawatts of heat and 15 megawatts of electrical energy are generated from 130 thousand tons of residual waste. A diesel engine instead of boiler and steam turbine, engine cooling water instead of boiler. By using the Diesel at fixed operating point of load and speed, in this case, as a heat source via cooling water, the thermal efficiency of the diesel engine increases to 80 to 90%.
