Scientists at the University of Copenhagen have developed a method to upcycle PET (polyethylene terephthalate) plastic into a substance that has the ability to effectively capture carbon dioxide. From Trash to TreasurePET plastic is one of the most widely used plastics worldwide, commonly used in beverage bottles, textiles, and numerous other products. The result is BAETA, a powder that can be shaped into pellets for use in carbon capture systems. They are currently exploring new sources of funding and investment to boost production and bring the material into commercial carbon capture operations. By converting bottles and bags into materials for carbon capture, the Copenhagen researchers demonstrate how pollution from one era could become part of the solution for the next.
