Prof. Reinhard Büchl celebrated his 75th birthday on 25.09. Reinhard Büchl has developed the family business into a successful Group with new ideas, innovative projects, and vision for more than 50 years – and always with a focus on sustainability and environmental protection. Reason enough to present the milestones of success: 1987 BÜCHL Disposal Consultation was founded by him (now: www.ELOGplan.com); 1993 was the start of a very successful cooperation up to the present with independent waste management companies (www.logex.de), 1997 organic waste collection and recycling started as a pilot project in Ingolstadt (now included in www.bioin-gmbh.de) and one year later passenger car prototype disassembly (now www.priorec.de). BÜCHL HUNGARIA an industrial waste management company is very successful through his commitment since 1999/2000 (www.buechl.hu). After handing over the operative business to the 3rd generation Reinhard Büchl built up the new Institute for Sustainability from 2017 (www.inas-institut.de) and up to the present supports strategic projects in the Group such as digitalisation www.cleverwaste.de). Not least, Reinhard Büchl has also shaped the branch: as President of the VBS (Bavarian Waste Management Association), Speaker for the Cluster of Environmental Technologies Bavaria, in the DIHK (Association of German Chambers of Commerce and Industry), and the VDI (The Association of German Engineers). Reinhard Büchl is closely linked with the TH Ingolstadt (Technical University of Ingolstadt) in Research and Teaching and is continuing to develop innovative ideas – also for the BÜCHL Group.
