CO2 can be used as raw material. There are several projects that aim to capture and reuse carbon dioxide as a technology to fight against climate change. For example, in certain industrial processes carbon dioxide can replace toxic organic solvents, which are more difficult to handle, and which leave traces in the substances with which they interact. There are research projects that use this gas as a coolant, as a raw material to manufacture carbonated beverages, for the cultivation of microalgae, to decaffeinate coffee and degrease cocoa, to eliminate pesticides from rice, to obtain oils and essences for cosmetics or the pharmacy, as an example of resources where you can be employed.
