million metric tons of electronic waste in 2019, up more than 21% over five years, according to the United Nations’ most recent assessment. Only about 17% of that e-waste was recycled, and what happens to the rest can be detrimental for both human health and privacy. The world generated a record 53.6 We have so, so, so many devices.

Panasonic develops thermoelectric tubes for compact geothermal electricity generation and waste heat recovery

Green Car Congress

Panasonic has developed novel thermoelectric tubes designed for fluid heat sources such as hot water and steam. Panasonic says that its thermoelectric tube is suited for capturing unused or wasted heat from hot springs and factories. W of electricity by running hot water of 90 °C inside, and cold water of 10 °C outside the tube.

LanzaTech collaborating with Swayana to convert waste gases from ferroalloy production to ethanol

Green Car Congress

South African engineering company Swayana has signed a Memorandum of Understanding (MoU) with LanzaTech to collaborate on developing projects for the production of ethanol and higher value products from waste gases in the ferroalloy and titania smelting sectors. In all cases, however, the production of ferroalloys is energy-intensive.

Scientists design adaptive material with tunable transparency and wettability; applications in pipelines, textiles, optical systems

Green Car Congress

A team of researchers at the Wyss Institute at Harvard University and Harvard’s School of Engineering and Applied Sciences (SEAS) have designed a new kind of adaptive material with tunable transparency and wettability features. As shown in the diagram, when stretched, the material confers the ability to reversibly “pin” droplets of water.

New self-propelled robotic device pinpoints leaks in pipes more accurately than existing methods

Green Car Congress

Researchers at MIT and King Fahd University of Petroleum and Minerals (KFUPM) in Saudi Arabia have devised a robotic system that can detect leaks in gas, oil and water pipelines at a rapid pace and with high accuracy by sensing a large pressure change at leak locations.
