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.
New research indicates that an optimal development of neighborhood solar energy might increase the total electricity produced by 5-10 percent, a significant gain by the standards of solar energy efficiency. At the same time, it can reduce the variability and unpredictability of the solar resource.
With a new method, a research team has demonstrated the potential to use methane not as a fossil fuel but as a versatile chemical building block with which to make more complex molecules, such as pharmaceuticals and other value-added substances.
A team of scientists is exploring an unusual source of electricity - damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida.
Scientists have discovered a novel way to make plastic from carbon dioxide and inedible plant material, such as agricultural waste and grasses. Researchers say the new technology could provide a low-carbon alternative to plastic bottles and other items currently made from petroleum.
