Background: Recently, unprecedented torrential rains have deluged the globe, resulting in disastrous floods. These disasters were caused by climate changes because of an increase in carbon dioxide (CO2) concentration in the atmosphere since the industrial revolution. Therefore, atmospheric accumulation of CO2 should be reduced to avoid a future climate crisis. Many methods to fix CO2 have been developed, but a practical method has not been established, except for the method using amines based on moderate plant constructions. However, the membrane method has not yet been established because of the conflicting relationship between penetrability and specificity, although membrane technology can be used for CO2 separation.

Methods: CO2 absorption and release from plastics were investigated, and CO2 penetration through polymer membranes was also investigated using polymer bags or latex balloons.

Results: Epoch-making discoveries for CO2 characteristics have been presented as follows: 1) the high penetrability of CO2 in the gas phase caused “pursued osmosis” against polymer elasticity; 2) highly penetrable CO2 passed through polymer membranes such as authentic polymers and natural cellulose, whereas neither O2 nor N2 penetrates these polymers examined; 3) CO2 is absorbed by plastics; 4) H2 and CH4 gases penetrate through polymer membranes, but their penetration was completely blocked in the presence of water; and 5) using a polytunnel made of polymer sheets (an artificial forest or positive green house), which allows CO2 penetration, instead of hard chamber, steel, or plastic could be cost effective.

Conclusions: High penetrability of CO2 compared with O2 and N2 through polymer membranes induces a “pseudo-osmosis”. Polymer membranes could be practically and economically useful for CO2 separation from the exhaust gas and atmosphere. The combination of the simple CO2 fixation and membrane separation could be imitated like an “artificial forest”.
