Circular economy: ancient populations pioneered the idea of recycling waste

Adkerson, who also chairs a global mining industry trade group, described the political situation in Washington as a “head-scratcher.” Biden officials understand the importance of copper to climate goals, Adkerson said, but are not likely to lessen mine permitting standards “because that just runs against the grain of their political situation.” Copper prices meanwhile are up 10% this month due to that low supply, with analysts expecting demand will increase alongside the global economy. RISING COSTS Freeport itself is not immune to that price rise.

A research team, led by Northwestern Universitychemists, has made a breakthrough in surface science by introducing a new active mechanism of adsorption. Such adsorption-based phenomena, in which molecules are attracted onto a solid surface,are essential for today’s catalysts, energy storage and environmental remediation. The research demonstrates how artificial molecular machines — wholly synthetic molecular components that produce machine-like movements — grafted on surfaces can be used to recruit molecules actively onto these surfaces at very high concentrations, thereby storing significant amounts of energy.
