Billund Bio Refinery demonstrates the results achievable, when collecting the most efficient and advanced wastewater solutions in one facility. The facility’s parallel wastewater and biomass synergistic treatment lines link both industrial and municipal waste treatment — effectively closing the local resource circle.
The dual-feed plant will treat both organic waste and wastewater, with a total capacity of 70,000 population equivalent and 4,200 tons of waste per year from both households and industries in the Billund area. The technologies have transformed the wastewater treatment plant into a modern biorefinery that converts wastewater and waste into clean water and energy.
The wastewater treatment process produces biomass, which is then treated to generate biogas for energy production that reduces the plant’s power requirements and creates additional income through the sale of surplus energy to the local grid. The plant’s environmental technologies enable the efficient combination of wastewater treatment and bio gasification of organic waste to produce three times as much energy as required to operate the treatment plant. Other plant byproducts will include efficient, odor-free organic fertilizer, and eventually, phosphorus and biodegradable bioplastics.
