Swiss Contribution

Sofies has many years of experience in introducing technologies in developing and emerging countries. The pyrolysis technology for the recovery of agricultural organic waste is being optimized in Switzerland at the Center of Appropriate Technology and Social Ecology, “Ökozentrum Langenbruck”.


Coffee pulp (coffee fruit pulp) is hardly usable in a direct way and pollutes the environment and climate through its decay. In order to secure the long-term existence of coffee farmers in Peru, technical and innovative solutions are needed. The thermal pyrolysis process uses biomass to produce energy and vegetable charcoal (biochar); thus transforming waste into valuable resources. The generated energy is used for efficient and quality-enhancing coffee bean drying, while the biochar is used as a soil conditioner. In a previous REPIC project (contract 2016.01), a successful know-how transfer of pyrolysis technology took place in Vietnam. Until now, the pyrolysis technique was only used for dry pulp. The objectives of this project are to adapt wet pulp technology, down-scaling the pulp plants for small-scale farmers in the Andes, as well as anchoring pyrolysis technology and using biochar in Peru as contributions to achieving global climate protection targets.
