AD+™ generates circular green hydrogen H2-C-H2 from organic waste & wastewater

Since 1980 we help industries & utilities worldwide to decarbonize and get more self-sufficient in both energy and water. We do this by converting their organic and nutrient waste streams to circular biomethane to replace fossil fuels, to clean water for reuse and to active biofertilizer for healthy soils and crops in both new and existing plants (retrofit upgrade).

Our latest AD+™ bioprocess technology as applied at full scale since 2013 generates up to 50% more biomethane with less residues and is up to 3 times faster than today's mesophilic AD (anaerobic digestion) for the highest ROI.

As to achieve the highest biomethane yield and water purification with the least residuals at the highest ROI, we apply our unique set of models, advanced biotechnology and deep expertise.

That's why our proven high efficiency 24/7 biopower systems with low cost buffer storage support the public power grid to complement the variable wind and solar power requiring expensive buffer storage.
