Swedish Energy Agency grants $2.6 million for commercial biosludge biofuel plant

In Sweden, the Swedish Energy Agency has granted C-Green Technology AB nearly $2.6 million to build a full-scale plant that converts industrial biosludge into biofuel. The project will be carried out in cooperation with StoraEnso in Finland. Approximately 13 GWh renewable biofuel will be produced annually, at the same time as the mill’s greenhouse gas emissions will be reduced by the equivalent of 7.000 tons of CO2 per year.

C-Green Technology has developed a new technology that transforms large amounts of wastewater sludge into something significantly more valuable. The process uses a technique called hydrothermal carbonization, which is based on nature’s own way of breaking down complex organic compounds into coal.
By treating the sludge with pressure and heat, C-Green’s process is able to achieve something that usually takes nature millions of years. The result is a dry and clean biocoal that works well as a biofuel.
