“After that, they become useless and you have to change your whole filter setup or buy a new one,” he said. Researchers at Rice University in Houston have developed a low - cost filtering material to separate and capture CO2 , from gas streams at natural gas gathering facilities . Cheaper and easier to make than other forms of activated carbon , the porous carbon material used for filtration will be commercially viable to produce at scale , says Maya Ghosh , a research scientist at Rice . She adds that the material is also highly recyclable and can be used more than 200 or 300 times . She also hopes the material can replace conventional amine - based scrubbers in refineries , power plants , and other industrial facilities .
