Green light for baking soda

A company in the US is taking waste carbon dioxide from power station chimneys and mixing it with sodium hydroxide to make baking soda. Waste CO2, it is claimed, can be captured in baking soda, ultimately reducing the greenhouse effect, according to Joe David Jones, head of the company Skyonic, which got the idea from an old college textbook. With the current craze for marketing provenance, will we soon be seeing ‘power station provenance’ such as ‘Traditional Drax Dumplings’ or ‘Authentic Sizewell Simnel Cake’?
