The development of the “circular economy” City of Borås has taken place over a long time during which the city’s waste and wastewater management, and district heating infrastructure has gradually been upgraded and its capacity expanded.
With a new wastewater treatment plant (WWTP) and biomass-based cogeneration plant, Borås has been future-proofed for the next generation. The new WWTP enables the proper treatment of increased wastewater volumes, while emissions levels of nitrogen, phosphorus and organic matter are at record low levels.
The city’s environmental impact will drastically decrease. Borås will now have one of the world’s cleanest WWTP while the CHP will produce environmentally smart district heating and renewable electricity for the Borås for many years to come.
Borås Energi & Miljö began construction in the spring of 2015 following an investment decision from the Borås City Council.
In May 2018, the wastewater treatment plant was commissioned and in spring 2019, the cogeneration plant began commissioning. Both plants will go into full commercial operation during 2019.
It is safe to have facilities that can do both heat and electricity and also be world-class, like this one, said Anders Ygeman, Minister of Energy and Digitization, who, together with Jennie Nilsson Minister for Rural Affairs, officiated at the inauguration at Sobacken.
