Determination of reliable CO2 emission factors for waste-to-energy …

Meanwhile, the BM has been routinely applied to several WTE plants for some years, providing a large set of data. The average site-specific emission factors for fossil CO (2) were found to be in the range of 260- 780 kg CO (2) t (-1) waste, and 30-67 kg CO (2) GJ (-1) energy of the waste incinerated. These values are significantly different ...
