He coordinated the EU project P-REX ( from 2012-2015 dealing with demonstration and assessment of nutrient recovery and recycling routes from wastewater. Christian Kabbe is a member of various European and national working groups and bodies dedicated to nutrient recycling in a circular economy. He leads the working group "nutrients" within the EIP-WATER Action Group ARREAU and is a member of the EIP-AGRI focus group on nutrient recycling.

He is member of the board of both the European Sustainable Phosphorus Platform and the German Phosphorus Platform. After joining the German EPA (Umweltbundesamt) as policy advisor and head of laboratory in 2008, he promoted the development of a reality based national roadmap towards sustainable phosphorus management and therefore initiated the sewage sludge ash monitoring program conducted by BAM 2013/2014.
