In the developed world, the lion’s share of CO2 is recovered from plants which produce ethanol (fermentation), reformer operations (in oil refineries), natural underground wells and to a smaller degree, ethylene oxide, titanium dioxide and even flue gas.
The most rapidly growing sector of this supply group has undoubtedly been fermentation, however this industry at large is in a state of reorganisation and development from grain-based to cellulosic, sugarcane, sorghum and algae.
The sugarcane-based plants found in places such as Brazil and Asia will continue, since this is a competitive and readily acceptable means of producing ethanol; and the CO2 by product will also continue to grow.
In terms of recovery, when we go to the developing world, where CO2 usage is usually limited to soft drink manufacturing and some cylinder gas use, often the sourcing is via combustion plants.
