Construction of a plant to convert sludge into biofuel.
On 2nd July 2018, the Swedish Energy Agency reported that it has granted C-Green Technology nearly SEK 22.7 million to build a full-scale plant that converts industrial biosludge into biofuel.
The project will be carried out in co-operation with Stora Enso and the plant will be built at its mill in Heinola. Approximately 13 GWh of renewable biofuel will be produced annually, and at the same time, the mill's greenhouse gas emissions will be reduced by the equivalent of 7,000 tonnes of CO2 per year.
C-Green Technology has developed a new technology uses pressure and heat to transform large amounts of wastewater sludge into a dry and clean biocoal that works well as a biofuel. The process uses hydrothermal carbonisation, which breaks down complex organic compounds into biocoal.
The Stora Enso mill in Heinola produces fluting (corrugated board material) and the new plant will convert about 25,000 tonnes of the mill's biosludge per year into biocoal. The biocoal will be used in the power boiler of the mill and to heat the nearby city of Heinola, with approximately 19,000 inhabitants. The plant is expected to become operational during the first half of 2019.
