Turning CO2 into baking powder

[CAPSLOCKSTUCK]

An industrial plant is capturing the CO2 emissions from a coal boiler and using the CO2 to make valuable chemicals. It is a world first.

The industrial plant appears especially significant as it offers a breakthrough by capturing CO2 without subsidy.

Built at a chemical plant in the port city of Tuticorin, it is projected to save 60,000 tonnes of CO2 emissions a year by incorporating them into the chemical recipe for soda ash - otherwise known as baking powder.

Here's how it works:

1. The plant operates a coal-fired boiler to make steam for its chemical operations.
2. CO2 emissions from the boiler's chimney are stripped out by a fine mist of a new patented chemical.
3. A stream of CO2 is fed into the chemicals plant as an ingredient for soda ash - a compound with many uses, including the manufacturing of glass, detergents and sweeteners.

The firm admits its technology of Carbon Capture and Utilisation won't cure climate change, but says it may provide a useful contribution by gobbling up perhaps 5-10% of the world's emissions from coal.

There are many uses for concentrated CO2, they had a greenhouse attached to the local power plant in Colorado, where the excess heat and water were used for year round growing operations for vegetables, and the higher concentration of CO2 allowed for faster growing times as well, workers just had to monitor it and or purge sections before entering. Fly ash was used in concrete, and as a road base material and for construction.

Its still dirty though.
