Most all of it comes as a side product. The amount of CO2 used for the applications listed pales in comparison to the amount used for urea (fertilizer) production.
- marcosdumay 5y agoWhat is different is that urea requires a power source that creates more CO2 than the chemical process uses. So you will certainly (as long as you are using fossil fuels) have a source available. Those things I mentioned buy their CO2 on the market. I have no idea where it comes from.
- noselasd 5y agoUrea production requires ammonia, and the production of ammonia produces co2 in large quantities. It's not without reason the two are almost always loacted closely
- markcyffka 5y agoGreat point & not so often talked about. Something like 230Mton of CO2 are used each year, a little more than half goes straight to urea production. By contrast only about 10% goes to the food/bev, medical, and other applications we are more familiar with on a day-to-day basis. plot showing the breakdown with some gov't sources. --> https://www.iea.org/reports/putting-co2-to-use https://www.iea.org/reports/putting-co2-to-use
