Sewage Treatment Plants

Sewage treatment plants are an important source of biogas. Surplus sludge that is formed as a residual product when cleaning household waste water is rich in organic material that can be utilized and generate energy using modern environmental technology. Biogas from sewage treatment plants is currently used primarily for electricity and heating, but increasingly also as vehicle fuel.

Residual Products Provide Energy

Biogas is extracted from the sludge that arises at the initial stage of the purification process. The sludge is utilized and passed on to specially developed digestive chambers where it is degraded in an oxygen-free environment by microorganisms into an energy-rich gas, consisting mainly of methane.

The gas is collected and converted by means of gas engines or turbines into electricity and heat. The methane gas can also be upgraded to biomethane for use as fuel for cars and buses.

The municipal sewage treatment plants today account for nearly half of the biogas extracted in Sweden. At the same time, there is an untapped potential as many treatment plants - thus far - have not yet invested in the technology. Moreover, the amount of recovered gas can be optimized by modernizing existing anaerobic digestion plants.
