Compressed upgraded biogas (biomethane/CBG); from food waste and manure; production, distribution, and use, minimum 97% methane
Includes pre-treatment of food waste at the biogas facility, anaerobic digestion, upgrading, distribution by truck and use of biogas in a combustion engine. Collection of food waste is not included in the dataset. Collection of manure is included in the system boundaries. Incineration and transport of reject from pre-treatment of food waste is included. No substitution of avoided products included.
Includes transport and combustion of the pre-treatment reject.
This dataset should be used when modelling the use of biogas in transport applications. When using manure for biogas production, the storage time (and related emissions) of manure is reduced. This effect is not included in the dataset. Furthermore, this dataset focusses on the impact on climate change. One should therefore be cautious in using this dataset to analyse other impact categories, especially toxicity. The ecoinvent database (version 3.7.1 allocation cut-off by classification) has been used for background processes.
1 kWh upgraded biogas from household waste and manure. As input material in the biogas facility, approximately 50% comes from household waste and 50% from manure sourced from surrounding farms. Production process: 1) Mechanical pretreatment to remove unwanted objects and reduction of particle size: screw press, grinder, hydro cyclone. 2) Sterilization process for 1 hour at 70 °C 3) Anaerobic digestion: Hydraulic retention time (HRT) 36.5 days. 4) Upgrading: water scrubber. Emissions from driving: EURO 5.
The biogas facility is located in the Vestfold and Telemark county. Manure is transported from local farms.
