World premiere of Exelys technology at Billund BioRefinery



Waste water treatment processes are called upon to converge with biorefining technologies. In some cases, those processes will be incorporated in a particular biorefinery model to treat their effluent efficiently and economically, minimise their net water consumption and obtain high valuable by-products. In other cases, waste water treatment facilities will be converted into real biorefineries. Billund BioRefinery, that is often called the Waste Water Treatment Plant of the Future, is an example of this second situation.

It is a joint project between Krüger A/S (Veolia Water Technologies subsidiary), the municipality of Billund and its utility company Billund Vand A/S. The plant has been designed to be a model of complementary waste water and biomass treatment technologies working in synergy. It will convert waste water 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.

The execution of the project advances successfully. Proof of this that the heart of Billund BioRefinery, the Exelys™ unit, was put into operation on 29th August by Anni Matthiesen, Member of the Danish Parliament and Spokeswoman on Nature. She performed the official inauguration of the plant whose technology celebrated its world premiere. Exelys™ is an innovative and complete sludge reduction solution that works in continuous mode, combining thermal hydrolysis and anaerobic digestion. The facility is the first full-scale demonstration of this state of the art process. Compact and robust, it reduces sludge cake through improved digestion and dewatering, while boosting gas production by 20 to 40 percent. Exelys™ handles all kinds of organic, industrial or municipal sludge and can also treat grease.
