The extraction of heavy metals from their ores with the ...

Study analyzes technologies’ climate efficiency in removing carbon dioxide from the atmosphere

One process has similar CO2 footprint to e-mobility

02-Nov-2021 - Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated. A research team led by Kavya Madhu and ...

New way to pull lithium from water could increase supply, efficiency
