Bio-NRGY, Belgique

In operation since 2012, Bio-NRGY, initially led by Eneco - a Dutch company specialising in the production of green energy - was taken over by Stefaan Delabie in 2014. The unit treats manure, slurry, agri-food industry by-products and glycerine. With a treatment capacity of 60,000 tonnes per year, it can recover 2.9 MWel of biogas through cogeneration.

Project description

Evergaz and Stefaan Delabie became partners in 2018 with the common intention of optimising the site’s industrial performance by finding distinctive digestate treatment solutions. As with the Am-Power site, they invested in an innovative digestate post-treatment process, which consists of extracting water from liquid digestate to reduce land application volumes while preserving the organic value of digestate as natural fertiliser for agricultural soil.
