Sewage and industrial sludge is being managed as a liability. Current outdated regulations and technologies focus on the least-expensive means of the sludge disposal. Sludge management needs to be redirected toward the recovery of energy and chemicals embedded in the sludge and guided by the principals based on the current scientific findings and technology. Environmental and demographic considerations need to play an important role in this new approach geared toward sustainable and energy-efficient waste management practices.
Working as an arborist in Colorado, Ryan Baldwin saw an opportunity to salvage city trees destined for the dump into usable lumber for woodworking projects.

There are two things that are true about biogas. The first is that biogas wants to happen. It wants to happen like plants want to grow, like fire wants to burn. And that force, that will to happen, has (at least) those two aspects: life, like the plants; and chemistry, like the fire.
Did you know that you're going to have to make your digester either much larger or much warmer, if you expect to do practical biogas in the US? Well, here's that story...
Renewable energy's ugly duckling comes of age.
Temperature is central to biogas production, and warmer is better. Much better. So if biogas is not a hot topic, it should be.
Summing up: How much food waste makes how much biogas to power what functions around the farmstead?
Wasting food in the U.S., making biogas, and using food waste to do it ... (Let's not waste all that wasted food!).
There’s a gold mine out back of your local restaurant in the form of wasted food. Learn to think like an ecologist and discover how nature turns “waste” into useable, renewable energy.
How can we clean up our rural spaces best. Is it up to individuals or governments?
