This dataset represents the production of electricity and heat from a biogas mix from different sources (biowaste, sewage sludge) when burning it in a cogeneration unit with gas engine. It is intended to represent the production of grid-connected electricity with biogas. The main product is then considered to be electricity at high voltage, while heat is produced as a co-product. The cogeneration unit has a capacity of 160 kWel; the degrees of efficiency are as follows: electricity: 0.37 and heat: 0.53. A mix of biogas is treated in this dataset with an average lower heating value of 22.73 MJ/Nm3.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
