Latest Patents
Roland Donaj holds a patent for a separation process for carpets. This process involves feeding comminuted carpet pieces into a stirred tank along with an aqueous solution containing separating salt. The mixture forms a first suspension, which is then processed through a mechanical separating stage. The result is a first high-solids phase, a second high-solids phase containing polymer fiber material, and a liquid phase. The second high-solids phase is further treated with a water-containing separation solution, leading to a second suspension that undergoes another mechanical separation. This innovative method allows for the efficient extraction of polymer fiber materials from carpet waste.
