When it comes to recycling, most people at least know how to dispose of things like plastic and aluminum. Food waste however, is another story.
It’s not that old food items can’t be used in other ways. It’s just much more difficult for recycling companies to sort through food waste when it’s usually combined with other things like paper plates and plastic spoons.
That’s where Harvest Power comes in. The company is able to turn food waste into energy. And it doesn’t need the food to be already sorted or “clean.”
Harvest Power’s anaerobic digesters can process large amounts of food waste mixed with things like oils and treated sewage.
That waste is then converted into usable energy. Currently, Harvest Power has a facility located at Walt Disney World in Florida. That facility processes the uneaten food waste at the parks and resorts and then sells it back to Disney as energy.
Last week, Tesla Motors announced an ambitious new product line: batteries to power homes or businesses.
The idea is that homes and businesses powered by solar panels could harvest and store energy during the day that could be used to run homes at night, or be used as a backup during a power outage.
“Our goal is to fundamentally change the way the world uses energy,” the company’s founder, Elon Musk, said at a news conference April 30. [Creative Genius: The World’s Greatest Minds]
Although the exact technology involved in the battery, called Powerwall, is a closely guarded secret, it probably isn’t based on revolutionary concepts, said Jordi Cabana, a chemistry professor at the University of Illinois at Chicago who studies new battery materials.
“Just looking at the specs that they publicize, it doesn’t look very different — in terms of the cost — to what they’re putting in their cars,” Cabana told Live Science.

Many major cities have seen a decline in driving over the past few years. The reasons for this are varied, but if it’s a continuing trend, it’s going to mean drastic changes for the way we shape our cities.

For Immediate Release
Washington, DC — U.S. Energy Secretary Steven Chu announced yesterday that $30 million in funding from the Recovery Act and FY 2010 budget appropriations will be made available to qualified small businesses to support the commercialization of promising new technologies. Today’s funding announcement builds on the Department’s existing efforts under the Small Business Innovation Research program (SBIR) and the Small Business Technology Transfer program (STTR) to develop near-term clean energy technologies and support American small businesses that will play an important role in building the clean energy economy of the future. This is the first time DOE has offered Phase III awards under these small business programs.
“Small businesses are the engine of job creation and innovation, and we need their ingenuity and entrepreneurial spirit to drive a clean energy economy,” said Secretary Chu. “By helping America’s small businesses bring these innovative technologies to market, we will spur economic growth and help reduce the country’s energy use.”
Small companies previously awarded Phase II grants through DOE’s Small Business Innovation Research program (SBIR) or the Small Business Technology Transfer program (STTR) are eligible. Projects that include developed technologies with a strong potential for commercialization and impact on U.S. manufacturing and job creation are encouraged to apply. Successful applicants may receive up to $3 million over three years to research, develop, and deploy new technologies.
Think the trend of businesses making green office renovations is just a passing fad? Not according to the latest issue of EL Insights, which reports that the U.S. green building market value will balloon from $71.1 billion now to $173 billion by 2015. Commercial green building is expected to grow by 18.1% annually during the same time period from $35.6 billion to $81.8 billion. In this case, green building is defined as building with resource use and employee productivity in mind.
