In the energy sector, George Sakellaris has a sterling track record. He founded Noresco in 1989, which was sold to Equitable Resources in 1997. Then in 2000, he started Ameresco to provide energy efficiency solutions throughout North America.

Now, the company has filed to go public and plans to raise as much as $125 million.

On April 26, 2007, Allied Waste Industries (NYSE: AW) announced yet another waste-to-gas project in their continuing effort to put a dent in America's dependence on petroleum fuels. The newest methane production project is being undertaken in concert with Ameresco, Inc., Columbia Water & Light, and the State of Missouri. It is expected that the methane recovery project situated at the Jefferson City Landfill in Jefferson City, Missouri, will produce more than 3 megawatts of electricity. That's enough wattage to power up to two thousand homes. Additionally, heat generated at the facility will be used to power two Missouri prisons.

The story as reported by Green Progress News indicates growing trash conversion interests for Allied Waste. To me, this signals excellent long-term prospects for growth and sustainability for the company. Donald W. Slager, president and chief operating officer for Allied Waste, stated: "With over a dozen alternative-energy projects in the various stages of approval and development, we expect that our portfolio will continue to grow in the future." Do these types of trash-conversion projects offer long-term profitability? Given their growing popularity I would like to think so, but experts in the field indicate that the conversion of trash to usable energy and the associated compounds produced through the process is a science that is still early in its learning curve. An enlightening discussion on the subject is presented by the Science to Life blog.

I tend to believe that investment in these types of ventures should for now remain restricted to simple methane-capture propositions, such as those being utilized by Allied Waste. There are some very futuristic developments on the horizon, and as with any budding technological field there is much yet to be learned and confirmed. Governments and industry are steadily pushing to find the holy grail of successful waste conversion, and there are some promising developments in the works, but it's all just science for now and there's little to find in practical use.

Perhaps the Flux Capacitor is just around the corner but I'm not holding my breath just yet.
