A new study shows that a low-cost sodium-ion battery currently used in cars and large-scale energy storage systems in China matches most performance parameters and production quality found in Tesla’s lithium-ion batteries. Since sodium is much more abundant and widely available than lithium, using it for batteries could cut raw material costs for manufacturers and […]

A pilot study employing a new method for treating sewage sludge efficiently created renewable natural gas while slashing in half the cost of the treatment. The Washington State University team described the process this week in Chemical Engineering Journal, touting it as a way to help communities sustainably clean up their waste while providing renewable […]

A man has powered an electric car using a homemade battery pack built out of discarded vapes, on a quest to show that so many valuable resources are being cast off every day. Last year, GNN reported that Chris Doel had stripped down the lithium batteries from 500 disposable vapes, power sources he describes as […]

A landfill 90 miles outside London is using methane from its waste to generate electricity and grow sustainable produce—even during the cold English winters. With the new approach to food production, landfill sites can become low-emission, affordable fruit and vegetable hubs with perfect year-round growing conditions. The huge dome in Wiltshire, England, serves as the […]
