    0.8 t/h Testing plant for biogas

    Working with a partner, we have developed a technology where we can use briquettes from straw in a biogas plant. As a result of the briquetting process, a small steam explosion is created and the cell structure is opened making access to bacteria and thus being able to increase biogas production.

    A biogas plant with supply of 100.000 tons slurry can increase biogas production from 2.5 million m3 of biogas to 6.5 million m3 by adding 10.000 tons straw briquettes.

    We have installed a testing facility at the biogas plant at the University of Aarhus in Foulum, Denmark. The briquetting press is a BP5500 and the line is complete with straw handling plant producing approx.. 800 kg per hour of straw briquettes with a diameter of 75 mm. The testing plant has enabled us to get documentation for the concept, which is now patented.
