Technology updates - new uses for carbon dioxide and methane 1

Carbon dioxide and methane: CO2 and CH4 are increasingly recognised as not just problematic greenhouse gases but also important feedstocks for a range of technologies. CO2 in industrial flue gases can be used to grow microalgae or be made into bioplastics. CH4 – from landfill sites or anaerobic digestion plants – can be burned to produce electricity but can also be converted into biodegradable plastics. There are many other uses for both gases.
