About Friedli AG
Friedli AG Engineering und Anlagenbau is a Swiss plant engineering company based in Burgdorf that has been planning and realizing process engineering plants for the processing of biomass and organic residual materials since 1992. Its range of services includes feasibility studies, concept development, planning, EPCM project management, turnkey production plants, and proprietary machines such as Sigma-series hammer mills (7.5–500 kW), pneumatic and mechanical conveying systems, and loading systems. Core industries are wood pellet plants (500–15,000 kg/h), animal feed plants, wood gasification, and biochar according to EBC certification, as well as bone degreasing and fat melting plants based on the acquired Carnitec technology. The company's own pellet production plant, LignoTherm Burgdorf GmbH, processes residual wood into pellets according to SN EN ISO 17225-2 and provides operating experience that flows directly into plant development. Services complement the offering: plant operation, maintenance, operational optimization, retrofits, 3D laser scanning, and BIM management.
