PROGRAMME - Monday8 September 1997 The European Waste for Energy network welcomes all the participants to “The Future of Biogas in Europe". This event is part of the ALTENER Programme 1997. The prime objectives are to create a forum for further development of biogas and to contribute to the dissemination of knowledge of biogas technologies. The main topics will be implementation, commer? cial exploitation and promotion of opportunities in anaerobic digestion and biogas energy conversion from organic waste, animal manure and a wide range of other biomass resources.
