Over the last year, our Research and Development Department has focused on innovative solutions and technologies that ensure the maximum customer benefit, while at the same time delivering only the most environmental sustainable products to the market.
The utilization of polyester fiber, made from 100% recycled PET, as adsorbent for the removal of Cu(II) from aqueous media was studied in batch experiments. The results have shown that polyester fibers produced by GreenFiber functionalized with organic dyes have the potential to be used as adsorbents for the removal of heavy metals, and this could be a solution for the sustainable use of the product, made from recycled raw material.
The presence of dyes in industrial effluents resulted from various industries such as textile dying and pigmentation, tanner, food, drug, pulp and paper has a substantial negative impact on the environment. Beside their coloration, most dyes could cause the pollution of aquatic flora and are responsible of the limited oxygenation of surface waters. From these reasons, even if the dyes toxicity is limited, the wastewaters that contain dyes cannot be discharged into the environment without any treatment.
Among the methods used for the treatment of industrial wastewaters, adsorption is a common process that has been intensively studied for this purpose, mainly because of its high efficiency and low cost of operation. Both these advantages are close related to the type of adsorbent material used in the removal processes.
