TRANSCRIPT
Nordic phosphorus Conference 2016, Malmö
Presentation of Billund Vand A/SWho are we?
• Utility company owned by Billund municipality• Drinking water
• Wastewater
• Organic waste
What do we produce?• Clean water
• Green energy and organic fertilizer
• Service to the costumer
• Supply consulting for:• Utility companies, national agencies, Circular economy task force in EU
• The Danish government support the new thinking in Billund.
• The Danish environmental minestry pay 2 mio. Euro to the project.
• We are thinking in reclaiming energy and nutrients from all sorts of waste…
Why? – because it´s good business and good for the environment
The former Danish environmental minister said:Aprox. 80 % of the Danish wasterwater facilities can and should be rebuild, to the model in Billund BioRefinery. In this way – we can ensure, we use the wastewater and organic solid waste to green energyproduction and reuse of resources as fertilizer and make clean water for the environment.
