The chemical industry is a major polluter, contributing 6% of global carbon emissions while often using toxic materials and fossil fuels. To solve this, Cambridge researchers created a "semi-artificial leaf" that mimics photosynthesis. By combining non-toxic organic parts with bacterial enzymes, the device uses only sunlight, water, and CO2 to produce a clean fuel called formate. This technology benefits society by providing a sustainable, non-toxic way to manufacture medicines and fuels, helping to clean up the planet while maintaining the essential products we need.
