This interesting project is a combination of different renewable energies, including in the installation a wind turbine, a biomass boiler and three ecoGEO heat pumps. The objective of the project was to deliver an efficient and renewable energy solution within a dairy farm with more than 750 cattle.

The function of both the biomass boiler and the heat pumps is the drying of recycled manure solids that are used in the same farm as bedding, a practice known as "Green Bedding". For this, heat is supplied through a closed water system through two radiators and then the air is channeled through the drying floor.

In addition to using an air turbine for the production of electricity, the system is even more efficient because during the days with wind production, the whole acts totally outside the electricity grid.
