Turning waste into power with bacteria - and loofahs

Loofahs, best known for their use in exfoliating skin to soft, radiant perfection, have emerged as a new potential tool to advance sustainability efforts on two fronts at the same time: energy and waste. A new study describes the pairing of loofahs with bacteria to create a power-generating microbial fuel cell.

New thermoelectronic generator

Through a process known as thermionic conversion, heat energy can be converted into electricity with very high efficiency. Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design, dubbed a thermoelectronic generator.

Quality recycled plastics

Some plastics can be recycled, but transparent film plastics are presently not considered worth reclaiming from landfill. An EU project aimed to change that, promoting flexible painted and laminated plastic film (commonly used for food, toys, cosmetics, and industrial parts) as a valuable recycling resource.
