This is another undeniable reason for optimism. There are literally thousands of projects like this happening around the world because of people who see possibilities and make them happen.

All Things Considered, March 25, 2008 · A proposed multimillion-dollar indoor urban composting facility would capture methane gas that rotting leaves give off and burn it to generate electricity for 1,500 homes, as well as to run on-site, year-round greenhouses. The city has not pinpointed a location for the indoor center, but it would be within city limits.

Like most major cities, Boston composts its yard waste in the open air. All those leaves from last fall wind up in drab, decaying mounds in a muddy clearing just south of downtown.

At the open-air site, Boston's Recycling Director Susan Cascino surveys the progress of the outdoor composting center by plunging a 3-foot-long thermometer into a pile of leaves that is as big as a house.

The needle goes up past 130 degrees. That means microbes inside are breaking down the leaves and releasing energy that originally came from the sun.

Right now both that heat and the byproduct methane are getting lost to the atmosphere. "It's a form of energy that we can capture," says Cascino.

In addition to yard trimmings, the new indoor composting facility would take food scraps from restaurants and hospitals.

"People think it's really cool that we can be more efficient with our wastes and put it back to productive use," says Boston's Environmental and Energy Services Chief Jim Hunt. "It's that old Yankee ingenuity here in New England and in the city of Boston."
