Facility Based on Household Waste Will Support 135 City Buses
Finland’s Wärtsilä is promoting delivery of a biomethane plant in Norway that will produce enough fuel to power 135 Oslo city buses. The plant, operated by Cambi AS on behalf of Norway’s EGE (Waste-to-Energy Agency) and the City of Oslo, will produce biomethane from household food waste.
The facility will produce LNG/liquefied natural gas (aka LBG, for liquefied biogas).
Wärtsilä notes that the LNG/LBG “can be efficiently transported for use as fuel.” The Oslo buses run on CNG/compressed natural gas – or CBG, for compressed biogas.

When fully operational, Wärtsilä says, the facility will treat 50,000 tons of food waste a year to produce around 14,000 normal cubic meters per day of biomethane – estimated to equal approximately 3,800 diesel gallon equivalents.
“The new facility’s liquefaction plant design uses conventional components in a mixed refrigeration process,” Wärtsilä says, noting that the design is based on more than 50 years of experience in the marine and oil and gas markets.
“There is huge potential for the use of LBG from renewable energy sources as fuel for trucks and buses,” Wärtsilä oil and gas systems managing director Tore Lunde says in the Oslo announcement.
“This project is an important step forward in developing this market,” Lunde said, adding, “This same technology can also be used in small liquefaction projects with other sources of gas as well.”
