Almost all cobalt can be recycled using new method requiring less energy with little environmental impact

Researchers have developed a more environmentally friendly way of retrieving cobalt from used lithium-ion batteries. With a liquid solvent made of readily available substances, derived from urine and acetic acid, over 97 percent of the cobalt can be recovered.

Electric, for sure. Sustainable, it depends. How green is my battery?

E-car batteries are crucial to meet the targets of the Paris Agreement, but can also have a high social and environmental toll. Experts warn of the urgency of a sustainable value chain and recommend an innovative solution: e-vehicles connected to buildings and repurposed batteries, to optimize the energy consumption.

Carbon emissions from fertilisers could be reduced by as much as 80% by 2050

Researchers have calculated the carbon footprint for the full life cycle of fertilisers, which are responsible for approximately five percent of total greenhouse gas emissions - the first time this has been accurately quantified - and found that carbon emissions could be reduced to one-fifth of current levels by 2050.
