Green chemists find a way to turn cashew nut shells into sunscreen

摘要

A team of international scientists has found an environmentally friendly way of producing potential sunscreens by using cashew nut shells, a waste material. The team of green chemists from the University of the Witwatersrand, along with colleagues from Universities in Germany, Malawi and Tanzania, are working on techniques to produce useful compounds from wood and other fast growing non-edible plant waste, through a chemical process named xylochemis-try (wood chemistry).
