The challenge that is dealt with is to purify the air in the office or home generally in a closed area, so people can breathe fresh air in indoors places. To achieve that it is needed pure oxygen which will be made by using recycled water to reduce the usage of water, then making electrolysis process for it as it will turn into two gases which are oxygen and hydrogen. Thus oxygen can be used in breathing in a closed area and the hydrogen is let to dissolve in air as it is not needed, but when people exhale they let out carbon dioxide gas from their lungs which is harmful for the environment as it helps to get the place hotter and uncomfortable, so it must be removed. That will be done by materials that can remove this gas. The idea is to install membranes that reserve carbon dioxide and can then be concentrated and compressed for storage. "Membranes are efficient and can save energy compared to other systems”, said professor Marco Giacinti Baschetti at university of Bologna, Italy. The membrane, developed by scientists at the Norwegian university of science and technology, consists of hollow fibers, about one millimeter thick, covered with an extremely thin layer of nano-cellulose and polymer mixed with artificial nucleos amino acids, made of wood fibers, 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. By these processes, the goal is achieved which is the purification of the air with high efficiency and use the waste of carbon dioxide to make useful organic compounds.
