“The sperm whale thrown on the beach of Knokke during the day was recovered as a biomass product after treatment in the Rendac processing plant of animal waste,” said the Belgian electricity producer Electrawinds, although it deplores “the death of this magnificent marine mammal.”

Indeed, the residual of the whale meat is classified as the fat of high quality that can not be used in the food chain to humans or animals. Electrawinds has developed a process that converts fat into this type of “green” electricity.

The sperm whale weighs about 25 tons and consists of 50% fat. After treatment at home Rendac Denderleeuw, where the fat is melted, the organic end product will be routed to the central biofuels in Ostend. Arrived, the biomass is purified in the refining division and turned into biofuel, which is then injected into the huge naval engines that produce electricity.

The 12.5 tons of fat of the whale can generate up to 50,000 kWh of green electricity. This corresponds to the annual consumption of 14 households (consuming on average 3,500 kWh per year).

Electrawinds states that innovative techniques in renewable energy used to recover the residual product in a sustainable way while producing “green” electricity.

Biofuel plant in Ostend has been operational since 2005 and mainly transforms CAT 1 fat from processing plants and animal waste from slaughterhouses.
