Existing Wastewater Treatment Plants (WWTPs) can, and should, be converted into Wastewater Resource Recovery Facilities (WRRFs) effectively delivering electricity and heat at market prices as net energy producers. Harvesting carbon early on within typical wastewater treatment processes, through pre-filtration, significantly increases the net energy production potential. The remaining carbon from energy production can be utilized as either soil conditioner or fertilizer depending on system setup and nutrient content.

To achieve MISSION ZERO, renasys must be combined with other innovative technologies to not only reach 100% energy self-sufficiency but also generate more electricity than consumed through daily operations.

 

According to powerstep.eu, in Europe alone, carbon from wastewater equates to a chemical energy potential of 87,500 GWh per year. This is equivalent to the output of 12 large power stations or 55,000,000 people. That is 14% of Europe's population.
 
The transformation of WWTPs from energy consumers to WRRFs as net energy producers reduces national dependence on fossil fuels and substantial reduction of CO₂e emissions playing an important role in decarbonizing the Water & Wastewater sector supporting broader energy policy objectives within climate change mitigation.
