BILLUND, Denmark – The new sludge to energy plant at the Billund BioRefinery has been officially inaugurated.

As a joint venture, it was delivered between Krüger A/S (Veolia Water Technologies subsidiary), the municipality of Billund and its utility company Billund Vand A/S.

The project will convert wastewater sludge and organic waste into biogas for local consumption, organic soil improvers for agriculture and bioplastics.

The dual feed plant will treat 4,200 tons of waste per year (a total capacity of 70,000 population equivalent) from both households and industries in the Billund area.

Sludge reduction technology – Exelys – from Veolia will be used on the site, combining thermal hydrolysis and anaerobic digestion.

The facility is the first full-scale demonstration of this process, said to reduce sludge cake while boosting gas production by 20% to 40%.
