The process of biogas formation is a result of linked process steps, in which the initial material is continuously broken down into smaller units. Specific groups of micro-organisms are involved in each individual step. These organisms successively decompose the products of the previous steps. The simplified diagram of the AD process, shown in Figure 3.5, highlights the four main process steps: hydrolysis, acidogenesis, acetogenesis, and methanogenesis.

Each of the chambers are filled with a texture that is
covered with bacteria film (biofilm)
Totally 472 m2/ 1620m2 of bacteria surface/film that
accelerate the transformation process in each step
Our value proposition: Biogas – at lower cost
Antec Biogas
FROM
▪ Fermentation tanks in general
• 20 – 30 days process time
• Large volumes due to longresidual time
• LOT of water, only 4-8% dry matter
• Large plants, costly to build
TO
▪ Antec is an alternative with
• More methane - faster
• 640 -1.560 m2 of biofilm surface
• 7 days process time.
• Less water, up to 15 % dry matter.
• Small size – containerbased or mobile solutions.
The key is focus on the biologic breakdown process in the tanks

Winner of the Bioenergy Innovation Award 2016
Innovations award for a new type of biogasreactor
The jury say:
• The winner this year represents a potential paradigm shift within the production of biogas. With their
solution, biogas may be a profitable solution for green energy, and one may expect a dramatic reduction of
the cost of biogas production.
