The Danish Energy Agency has entered an agreement with Thai company Sima Interproduct Co. Ltd. on a biogas project in the Kalasin province in northern Thailand, writes the Danish Energy Association in its daily newsletter. The agreement is part of the Danish state programme for development of climate projects in developing countries also known as Joint Implementation/Clean Development Mechanism (JI/CDM) projects.
Sima Interproduct Co. Ltd produces starch, and the wastewater from this process is normally fed into lagoons. In these foul-smelling lagoons, microorganisms turn the wastewater into methane, which is then released into the atmosphere. Methane is a potent greenhouse gas whose contribution to global warming is 21 times more powerful than CO2.
The project that the Danish Energy Agency is involved in concerns installation of a biogas system, which will process the wastewater, capturing the methane and turning it into useful biogas. The latter will then be piped to a gas engine that generates electricity, which will be used at the factory and surplus electricity sold to the grid. The biogas system is expected to be fully operational in two weeks, and estimated to save the equivalent of 60,000 tons of CO2 emissions annually.
