Finland's previous plans have involved considerably larger gasification-based diesel plants, the raw material demands of which could not have been satisfied with locally sourced waste. Finland 's VTT Technical Research Centre has created a sustainable way of turning forestry by - products into transport fuels . The system uses gasification to convert bark , wood and other waste into intermediate products , such as liquid hydrocarbons and ethanol , in plants that are integrated with industrial or district heating plants . Oil companies then process these products into renewable fuels or chemicals .
