Tomatoes: The Next Alternative Power Source

 How does a tomato become power? A group of researchers at South Dakota School of Mines & Technology has found a way to treat the problematic waste and turn it into something useful: electricity.

Every year, the state of Florida throws out nearly 400,000 tons of tomato waste.

The sludge is a mixture of damaged or worm-eaten tomatoes as well as unwanted skin and seeds from processed products like ketchup. It goes into landfills where it can produce dangerous methane gas, or ends up in waste water.
The researchers have developed a special microbial fuel cell to process the waste and turn it into electricity. It uses bacteria to break down the organic material in the tomato waste, oxidizing it and generating an electrical charge. The process also neutralizes the waste so that it no longer emits greenhouse gases.  
The research is currently being led by Namita Shrestha and other scientists under professor Venkataramana Gadhamshetty. They presented their latest research at the American Chemical Society national meeting in San Diego on Wednesday.

The entire process takes a few weeks to complete, and the power output from the tomatoes begins to die off after 10 to 14 days.
