There's a local sewage treatment plant that's producing fertilizer[1] and selling it. Why couldn't this be done on a large scale? [1] https://www.cleanwatergro

- tastyfreeze 5y agoAll of our sewage waste treatment could provide two things methane and fertilizer. Most treatment plants are aerobic so they don't produce methane. But, every treatment plant could provide fertilizer if regulations in the area allowed it and people bought it. I would like to see a shift to anaerobic sewage treatment to produce methane for fuel everywhere that humans live. I have been thinking about what it would take to convert my septic tank to an anaerobic digester for many months. I would love to replace my propane supply with methane produced from my own shit. On a larger scale I believe that my remote community could similarly replace a large portion of the imported propane with natural gas if we had an anaerobic sewage treatment plant. https://www.veolia.com/anz/our-services/our-services/energy-services/waste-energy/biogas/biogas-wastewater-treatment-plants https://www.veolia.com/anz/our-services/our-services/energy-...
