Closed circulation

Detailed description of the Good Practice

Modern food production is based on fossil fuels, and the production together with logistics requires a significant amount of energy. Fertilizers are problematic as well; the world is running out of phosphorus during this century and yet it is being wasted in agriculture. Fish farming usually has a negative effect on the quality of nearby waters. Modern energy and food production are dependent on fossil fuels and produce emissions harmful to the environment.

More Details of the Good Practice

The system consists of a fish farm, greenhouse, biogas plant, power plant/ CHP unit, wind mill and biodiesel plant.
The nutrient rich water from the fish farm is circulated to the greenhouse. The biogas plant situated on a landfill will utilize both the gases from the landfill itself and from incoming waste masses including fish and vegetable waste from own production. The gas is used in the own electricity production.
The CO2 produced in the generator will be purified and used in the greenhouse to accelerate growth. The excess heat will be used in the fish farm and nearby businesses. The combination of biogas (multi-fuel power plant) and wind power guarantees a stable and reliable source of electricity.
The fish waste from the fish farm is used in own biodiesel production. The logistics of the whole system can be powered by this biodiesel. The soil enrichment material from the biogas plant can be used as fertilizer.
The system produces energy and food locally and with very small emissions. The basic idea is transferrable to anywhere in the world and can be customized according to local conditions.
