Christian started his professional career in the chemical industry in 2003. He joined the German EPA (UBA) in 2008 where he promoted the development of a national strategy for sustainable P management. In 2011 he moved to the Berlin Centre of Competence for Water as program manager for resource recovery from waste(water). At ISLE Utilities (2017-2019) he continued the know-how transfer into practice. Since early 2019 Christian is managing director of the German branch of EasyMining, a daughter company of the Swedish Ragn-Sells Group, having developed technologies for nutrient recovery from secondary sources. Since 2021 he is also MD of Phosphorgewinnung Schkopau GmbH, a J/V between EasyMining and Gelsenwasser currently implementing the first Ash2Phos full scale plant in Schkopau, South-West of Berlin. Christian is co-founder and board member of the German and European Phosphorus platforms and supporter of the Clean Phosphorus initiative. He is engaged in DWA, International Fertiliser Society (ifs) and engaged in various European and German committees.

After finishing his PhD on sustainable wastewater systems at TU Berlin, Christian joined KWB in 2010 as expert in Life Cycle Assessment. His work focusses on measuring environmental sustainability of all aspects of the urban water cycle, expanding the perspective beyond the water sector to linked fields such as agriculture, energy, and industry. He is leading the group on “Energy & Resources” and explores emerging topics such as circular economy, industrial symbiosis, green energy and sector coupling, and greenhouse gas emission accounting. Combining his engineering background with scientific assessment methods, Christian has been involved in multiple European and national projects on circular economy in the water sector and brings a holistic life-cycle perspective into the discussion on sustainability of this emerging concept.

Christoph Blöcher holds a diploma in Environmental Engineering from Technical University of Berlin and obtained a PhD from Saarland University (membrane bioreactors). He had various positions in the chemical industry at Bayer Technology Services, Currenta and now Covestro, being always linked to water. He developed and implemented wet oxidation processes, consulted globally sites and plants, and was plant manager water supply for a chemical parc. He is now Head of Infrastructure Processes, Materials & Corrosion in the Process Technology organization of Covestro, supporting sites and plants in troubleshooting, projects and the transition to circularity and climate neutrality. He always believed that a substantial contribution can only be made with a strong internal and external network.
