Sewage treatment isn’t rocket science – except when it is
It’s a case of finding a use for what was thought of as waste. Sewage treatment processes produce methane and nitrous oxide, both greenhouse gasses, while leaving undesirably high levels of nitrogen in the discharged water. On their own, all three of these things are harmful to the environment. Stanford University reports that a team…
