In October 2023, Cré and the REA held a study tour of wet and dry-AD plants in Germany. Delegates from the UK and Ireland assembled at Munich airport. Josef Barth, an international expert in organic waste treatment, quality management, compost quality and marketing, led the tour. The group visited:

• Oko Power, a wet-AD plant in Altenstadt
• VIVO Municipal Enterprise, a dry-AD site in Warngau
• ZAW-SR, a dry-AD plant in Aiterhofen
• AWG Donau-Wald, a dry thermophilic plug flow system in Passau

At dinner in Straubing, the group also received a presentation from Horst Müller about the 3A Biogas process, and their two reference plants in Austria. Thank you to Percy Forster of Cré and Josef Barth for organising the study tour and to all the hosts who were welcoming and open in sharing information about their process.
