Objectives and outcomes

After Brazil, Vietnam is the second largest coffee producer in the world. With more frequent rainfalls during the harvest season, coffee drying is becoming a big challenge for farmers, as the traditional sun drying is not reliable . 

The objective was to introduce the Pyrolysis technology into Vietnams coffee sector to provide reliable heat for drying and biochar, a valuable soil enhancer. The technology has to meet strict requirements: can be locally built and maintained, is compliant with international quality standards, can be integrated in existing drying systems and is affordable!   

The outcomes were the following:

  • Research and Development of a new Pyrolysis machine in Switzerland
  • Technology transfer from Switzerland to a Vietnamese equipment provider
  • Transforming the Pyrolysis system into a concrete business case.
  • A successful market introduction in the coffee sector and first exports of equipment. 
  • The technology shows high potential to serve also for different agro-food industries, such as rice, coco, bamboo and cashew
