Siam CIGAR

Waste water from the company’s Siam and Lamthap factories is now treated in covered in-ground anaerobic reactors (CIGARs) to digest the high organic content in the waste. This innovative digester technology to capture Methane biogas was designed for Univanich by Waste Solutions Ltd, an international firm of consulting engineers specialising in biogas technology.

Methane biogas is normally a very damaging greenhouse gas but at the Siam and Lamthap factories it no longer escapes to the atmosphere but is used as a fuel. Two large biogas engines were imported from the Guascor company in Spain, each capable of generating up to 950kw electricity for supply to the provincial grid.
