What is Viking's biogas?
A separate initiative introduced on Viking Line cruise ferries is conversion of cruise ship food waste into biogas. Environmental management company, Envor Group, collects ship biowaste at port in Helsinki and transports it for processing. As a result, biowaste on Viking ships has been reduced by approximately one third. Envor then transforms the waste by a biogas purification process, with resultant biogas created that is suitable for use in vehicles. The biogas could even theoretically be liquefied and transformed once again into fuel suited for use in Viking Line cruise ships.
