Chemical Process Produces Critical Battery Metals With No Waste

Cars That Think

At some mining sites, olivine is a waste product, stored in piles on the surface. Christchurch-based Aspiring Materials has developed a patented chemical process that produces multiple valuable minerals from olivine, leaving no harmful waste behind. They’re extracting value from every component they produce, and with low to no waste.

New Mærsk Triple-E ships worlds largest and most efficient; waste heat recovery and ultra long stroke engines contribute to up to 50% reduction in CO2/container moved

Green Car Congress

Four-hundred metres long, 59 meters wide and 73 meters high, the Triple-E is the largest vessel of any type on the water today, according to Mærsk. Two ‘ultra-long stroke’ engines turn two propellers, and specially optimized hull and bow forms guide the vessel through the water at the speeds typical in the industry today.

NRC report concludes hydraulic fracturing poses low risk for causing earthquakes, but risks are higher for wastewater injection wells; CCS impact undetermined

Green Car Congress

Schematic diagram of a shale gas well following hydraulic fracture treatment, with the relative depths of local water wells shown for scale. Hydraulic fracturing (“fracking”) extracts natural gas by injecting a mixture of water, sand, and chemicals in short bursts at high pressure into deep underground wells.
