CASE STUDY / ROVERETO SEWAGE TREATMENT PLANT

Biogas

Wastewater and landfill treatment plants that require low-methane biogas achieve the highest level of efficiency through our expertise.

COGENERATION WITH BIOGAS FROM SLUDGE AND OFMSW

Biogas cogeneration plant from sludge and OFMSW

The Rovereto municipal wastewater treatment plant has adopted the first integrated system that combines fermentation of wet waste, OFMSW, and oil-free microturbines to achieve maximum energy efficiency with a view to environmental sustainability.

Biogas is produced from the purification of water and sludge and from the OFMSW (organic fraction of municipal solid waste) to power two 200 kWe Capstone turbines. The electricity produced is self-consumed entirely by the Rovereto treatment plant, which thus sees its electricity bill drastically reduced, while the thermal energy is used to heat the anaerobic digesters, the office building and the FORSU shed. The surplus is sold to a nearby sludge drying plant.
