A new concept for a flow battery functions like an old hourglass or egg timer, with particles flowing through a narrow opening from one tank to another. The flow can then be reversed by turning the device over.
Whey from cheese production and other agricultural waste can be a valuable raw material for new biodegradable plastic. A European research project is working on using these by-products in laminated cardboard for food packaging.
To cut down on the environmental waste and provide storage for rural communities, researchers have proposed a model for recycling unspent lithium ion batteries from smartphones into energy storage units for solar-powered LED lamps.
For the first time ever, researchers connected nine biological-solar (bio-solar) cells into a bio-solar panel. Then they continuously produced electricity from the panel and generated the most wattage of any existing small-scale bio-solar cells - 5.59 microwatts.
About a tenth of overall global greenhouse-gas emissions from agriculture could be traced back to food waste by mid-century, a new study shows. The findings for the first time provides comprehensive food loss projections for countries around the world while also calculating the associated emissions.
