Our development in this project is to get rid of carbon dioxide by using membranes. These function to reserve this gas. And this is very important given the negative results this gas causes. The membrane is consisting of hollow fibers, about one millimeter thick, covered with an extremely thin layer of nanocellulose and polymer mixed with artificial nucleus amino acids, made of wood fibers, it allows carbon dioxide while blocking other gases, the amino acid grabs onto Co2 and pulls it across the membrane. After the carbon dioxide particles are trapped inside the membrane, it can be used to make useful organic compounds, such as use the retained carbon dioxide in the manufacture of the polyurethane compound, which can be used in many industrial applications in garments, household applications, and packing.
