Swiss Contribution

The Swiss Ökozentrum Langenbruck has many years of experience in the development of sustainable energy technologies and projects for developing countries. Sofies-Emac has expertise in the area of resource efficiency and clean production technologies (Cleaner Production) in food production, especially in the coffee and rice sectors.

Description

Peru’s coffee cultivation is strongly segmented. A lot of different farms are producing coffee on small plantations. The fruit pulp is the coffee production’s main biomass waste product. The humid and non-combustible coffee pulp is slightly acidic, hardly compostable or fermentable, not suitable for animal feeding and may pollute the ground water. Another aspect is the high potassium content that was extracted by the coffee plant from the soil.

This REPIC project’s main goal is the development of a simple pyrolysis plant designed for continuous operation. The pyrolysis plant will deliver both heating energy for the drying process and potassium rich bio char that can be used as fertilizer. It is planned to distribute the new pyrolysis plant in collaboration with a local producer of coffee-production equipment; partly within the UNIDO RECP initiative’s framework, starting in 2014.
