New technologies turning Edmonds wastewater plant from sewage incinerator to green biofuels...

A thoughtful read!

..."Sewage treatment is not a topic that normally generates excitement. Quite the contrary, when we flush the toilet, we just want it to go away and not think about it further. But the hard truth is that there is no “away”– it all has to go somewhere, and traditionally that somewhere is in the air as greenhouse gases such as carbon dioxide (CO2) and either landfilling or surface spreading the solid portion.

But that is about to change in Edmonds with the addition of new equipment being installed the in city’s wastewater treatment plant. Pioneered by Pittsburg-based Ecoremedy, it promises to cut CO2 emissions to near zero, reduce the plant’s electrical consumption by a third, eliminate the need for fossil fuels necessary for the old incineration process, and convert residual solids into a marketable product that will not only stay out of landfills but will provide Edmonds with a new revenue stream.

An additional plus: The new process is self-sustaining, meaning that it produces more energy than it uses, turning what was once a sewage sludge incineration plant into a city-owned renewable energy producer."...
