The BiEnergy concept is a holistic approach for a sustainable bio energy cycle, which is also capturing greenhouse gases from the biggest polluter in the world…...farm animals!
Hovedelementer fra BiEnergy konseptet:
| Manure treatment prior to transport to bio gas plant
|
- The fluids are separated from the solids (8-10% solids), purified and disposed of to e.g. irrigation
- Transport of energy packed manure solids reduced to 1/10
|
| Methane production
|
- Water and other organic compounds are added.
|
| Production of electricity (ThermoConverter)
|
- Electricity is produced with up to 70 % efficiency (compared to 30-40 % for existing technologies) and lower maintenance cost
- Consequently, twice as much electricy is produced per unit CO2 emission
|
| Waste treatment from bio gas production
|
- Fluids and solids are separated
- Solids are enriched and used as fertilizer
- Fluids are used to grow bio mass
|
| Produciton of bio mass
|
- Algaes and water plants are grown in the fluids from the bio gas plant, with supply of waste heat and CO2 (for photosynthesis - developed in cooperation with the University of Ås) from the production of electricity
- Bio mass used for
- Bio diesel
- Animal fodder
- Re-used for methane production in bio gas plant
- Waste water is used for irrigation

The BiEnergy concept is developed by Energreen Bio AS and Vekst Foundation.
