Alexander Rütjes

Co-founder and managing director

Alexander Rütjes is a co-founder and managing director of HRG Polygon One GmbH in Düsseldorf. In the journal he writes about the EU Deforestation Regulation (EUDR) and the EU Packaging and Packaging Waste Regulation (PPWR): about deadlines and legal acts, about the due diligence statement and the EU declaration of conformity, and about the data companies actually have to gather for them. Every article closes with the legal sources used and the legal status it refers to.
