Web170516: Extracting additional value from anaerobic digestion of difficult wastes

About the webinar

Anaerobic digestion of problem wastes can be made very attractive by the extraction via anaerobic digestion of valuable products such as nitrogen, ammonium sulphate and solid organic phosphorus fertiliser.

Ductor of Finland have now commercialised the processes and offered to discuss these with us. Fermentation technology enables the removal of over 60% of the nitrogen contained in organic waste materials. The microbiological solution reduces a controlled amount of nitrogen from the substrate prior to the anaerobic digestion process.
