Billund BioRefinery (BBR) is a resource recovery plant that integrates urban waste management and wastewater treatment with circular economy. Energy, clean water and nutrient rich natural fertilizer are produced, all whilst effectively cleaning all the influent waste streams and protecting the environment. The facility is a modern day refinery that uses waste streams instead of traditional crude oil to generate electrical and heat energy and to produce cleaned water and high quality natural manure. The BBR receives urban wastewater and source separated organic household wastes along with organic industrial wastes. These streams are processed through a generic wastewater treatment plant, and a highly effective three step anaerobic digestion syste.

BBR is thus able to generate 3 times the energy it uses in its entire concern which includes the energy for water supply, sewerage collection and the treatment processes themselves. This excess energy is sold to the local electricity grid and to the district heating grid. The nutrient rich natural manure is supplied to the local farming community thus improving phosphorous security.
