Enerfish, producing biodiesel from fish industry

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) April 1, 2010 --

ENERFISH is a European project, based in Vietnam, working on producing biodiesel from fish wastes. Enerfish is a new polygeneration application project with energetics news perspectives for renewable energy sources built up and demonstrated for the fish industry. The distributed energy system utilizes cleaning waste of a fish processing plant to produce biodiesel . The biodiesel is used to produce the locally needed cooling/freezing and heating energy. Ernerfish is an European project co-funded by the European Commission. The technologies are to transform fish wastes to fish oil , fish oil to biodiesel , biodiesel to heat and power , end uses and by products .

Under the coordination of VTT, the Technical Research Centre of Finland, a new polygeneration application with renewable energy sources is being built up and demonstrated for the fish industry. The distributed energy system utilizes cleaning waste of a fish processing plant to produce biodiesel. The biodiesel is used to produce the locally needed cooling/freezing and heating energy. In addition, a power surplus is generated for injection in the electricity network or onsite industrial use.

The research contribution focuses on optimisation, simulation, validation and planning of piloted concepts. An energy integration auditing and optimisation tool is developed to carry out feasibility studies for the fish industry. The advanced CO2 based freezing/cooling system requires optimization and control system planning of special high-pressure equipments. The final biodiesel will be tested in appropriate engines.

The demonstration will take place in Vietnam, where the fish processing industry shows particular wealth. At the demonstration site, the main product of the fish processing plant is catfish filet (about 40 tons/day). The fat content of 22% in the cleaned fish wastes results in a potential production of biodiesel of about 13 tons/day. A part of biodiesel is used to produce electricity for the locally needed cooling/freezing (0.3 MW) and heating (1,3 MW) energy. In addition, a power surplus (0,8 MW) is generated for the local industrial use.
