Vegger Biogas Plant

Vegger Biogas is Denmark’s oldest biogas plant from 1986 which was part of the Danish Village Energy Plan. A major expansion was completed in 2014 which involved replacing the old bark filter plant with a safe and effective biofilter that could match a much larger odour formation and meet the stricter regulations for odour elimination.

 

During the tender phase, BBK was the only biofilter manufacturer able to guarantee odourless plants without complaints from neighbours. During the design phase, there was close cooperation on the design of the air ventilation, with BBK using e.g. smoke mists to pinpoint extraction and piping. The new plant was therefore fully upgraded from its first day.

The biofilter is built in two sections in concrete elements. BBK has supplied the extraction system/piping, buildings and filter solution.

Capacity

150.000 tonnes of biomass/year

Production

7,1 million m3 biogas/year

Filter capacity

30.000 m3 /time

Dimensions

Pre-filter 45 m2
Biofilter 230 m2

Lifespan

8-15 years depending on concentrations in the air being passed through the biofilter

“Our ambition was to deliver cheap energy to the village and not expose the neighbours to odours. We have achieved this in full. After a seamless delivery by BBK, we now have a service contract with quarterly visits and technical service. BBK is often at the forefront of improvements and there have been no critical comments by the environmental control authorities after their inspections. I can’t recall a single issue during our partnership, and the communication has been straightforward. Everything has gone very smoothly.”

Vegger Biogas converts sludge, slurry and biological waste into biogas. Built for 60 t/day biomass, it has now been expanded to 400 t/day. The much larger quantities handled in a smaller community place high demands on the identification of processes and a dense piping system for extracting odours from tanks, warehouses, etc., so that all odours are removed in the filter system and nothing escapes.
