Fish bones find a different current

RESEARCHERS in Japan are using fish bones discarded from processing plants to generate electricity.
Led by a team of scientists from Tohoku and Nihon universities, the process utilises methane gas produced from the bones to produce electricity, reports The Asahi Shimbun.
By mixing the bones with sludge in a tank and fermenting them, methane is created, which is then burnt in a gas turbine to power an electric generator.
Chika Tada, associate professor of environmental microbiology at Tohoku University’s graduate school of agricultural science, explains: ‘If such power generation proves profitable, we hope to install the generators at school lunch processing centres and restaurants in highway service areas.’
The scientists have been working on the experiment with equipment that has been installed in the car park of a seafood processing plant.
The aim is to produce 144 kilowatts per hour – equivalent to 1.5 households – using 200kg of fish bones per day, power that would be used at seafood factories, with any excess being sold to Tohoku Electric Power Co.
