Hindelbank - Indonesia ranks as the fourth largest cassava producer in the world. Because of its starchy tubers, cultivation of the cassava plant is an essential part of agriculture in Indonesia. In the Lampung region on the island of Sumatra, the Sahabat Group is expanding the existing production of cassava starch. During the process of extracting the starch, waste water is produced which flows into lagoons specially constructed for this purpose. These covered lagoons act as large anaerobic reactors and as the organic substances break down, biogas is formed. This biogas is subsequently cleaned, conditioned and converted, contributing to a cleaner environment.

The Sahabat Group presented the biogas project to the UNFCCC, the official authority for CO2 emissions trading, and it was approved. They are now authorised to produce CER (Certified Emission Rights) which can be traded. Furthermore they will supply the biogas to gas engines for the purpose of generating electricity. This electricity is mainly used to satisfy its own
power needs.

The criteria set by the UNFCCC are extremely stringent. The Sahabat Group needed a partner who is highly experienced in designing and building a plant which is fully compliant with these stringent rules. That is why the customer chose a supplier who is able to provide worldwide references in this field and awarded the order to Hofstetter Umwelttechnik AG.
