Treatment of digestate:
Christiaens Group recognizes the changes in the organic waste treatment market.
For certain waste streams the composting process is more and more replaced by anaerobic digestion. Christiaens Group acknowledges this change and thinks both systems work complementary to each other. Digestate from the AD-process requires less composting due to the already extracted energy. The final composting can be done by using a part of the generated electricity and heat from the CHP. This combination significantly reduces the carbon footprint while keeping the same compost output.
