Among the many benefits of sustainable communities is the ability to create closed eco-systems that can manage resources capable of creating renewable energy. Sweden's EPA-equivalent puts ours to shame. They have developed an extremely comprehensive and thoughtful plan that looks at the environment in a holistic manner. One of the results of that is the way that municipal waste is managed. Each municipality owns and operates its own wastewater treatment facility and they are responsible for what they produce. The sludge that results from the wastewater treatment process is not shipped to other regions of the country; it's used by the municipality to create biofuel, syngas, and other renewable energy sources. Syngas can be used to generate enough energy to power the plants that create it. It can also be used as a component in the production of other biofuels. Homes are heated and powered by poo. Cars run on it. In fact, the government provides subsidies to those who fill up their tanks on the biofuel created from poo.

This is a great idea. At the very least, the EPA needs to take another look at the approved use of "biosolids" as fertilizer. We are poisoning our food supply. There are plenty of scientists who have declared it an unsafe practice because of the chemicals and pathogens that remain even after our waste is processed. Sludge is a toxic stew. People who live near sludged fields are becoming sick and some have died. It is a travesty that the agency that is supposed to protect us and our environment approves the use of sewerage waste on the fields we grow our food in.
Methane from pig waste. I live in Iowa and we could be making all kinds of energy by tapping our animial waste methane gas.
