Wastewater treatment plant into carbon sink

Carbon sink

Wastewater treatment plants are among the big energy consumers in our societies and they have  a significant carbon footprint. Continuous efforts are getting the treatment plants closer to energy neutrality, but often there’s potential to do even more. In addition to energy optimization also direct greenhouse gas emissions must be under control.  Nitrous oxide and methane can constitute an important part of the carbon footprint in the wastewater treatment plants and efforts are needed to efficiently mitigate them.
