As a design and consultancy bureau specialised in the treatment and the recovery of organic waste and effluents, EREP has a specific expertise in the field of biological treatment and more particularly in the production and use of biogas. Created in 1980, we are located in Aclens, near Lausanne, in the French speaking part of Switzerland. With more than 40 years of experience, EREP assists at the phase of project definition as well as during its realisation and assures assistance on site. EREP represents the official competence centre for biogas energy from biomass in the French speaking part of Switzerland. Its shareholders are perfectly independent of groups and constructors active in the field, which gives EREP a complete neutrality in its analyses and advice.
