CUSAT find ways to recycle used medical masks as engineering products
February 10, 2021

Plastic fibres separated from the used medical face masks could be blended with rubber to make polymer compounds and manufacture engineering products. Disposal of face masks in these pandemic times has turned out to be a challenge for many. The researchers at Cochin University of Science and Technology (CUSAT) have developed an innovative method to recycle these used medical face masks as engineering products.
Prasanth Raghavan and P. M. Sabura Begum faculties at CUSAT, who jointly guided the research, said that the plastic fibres separated from the used medical face masks collected from various sources could be chopped and blended with rubber to make polymer blends with high tensile strength, impact strength and thermal properties. This can be used to manufacture high-performance engineering products such as car bumpers, dashboards, fighter jets and submarines as protective shielding

Overview:
Phycocyanobilin (PCB) is a natural blue chromophore found in cyanobacteria. PCB is expected to be applied as food colorants and pharmaceuticals with anti-inflammatory and antioxidant properties. PCB also functions as the chromophore of photoswitches that control biological functions in synthetic biology. PCB is covalently bound to phycocyanin, a component of photosynthetic antenna protein, and its extraction requires specialized expertise, time-consuming procedures, and/or expensive reagents. A research group led by Assistant Professor Yuu Hirose at Toyohashi University of Technology succeeded in developing a highly efficient and rapid extraction method for PCB by treating cyanobacterial cells with alcohol under high-temperature and high-pressure conditions. They also demonstrated that this method can be applied to the isotopic labeling of PCB and its reconstitution with photoswitch protein. Th

With ever-worsening climate change, there is a growing need for technologies that can capture and use up the atmospheric CO
2 (carbon dioxide) and reduce our carbon footprint. Within the realm of renewable energy, CO
2-based e-fuels have emerged as a promising technology that attempts to convert atmospheric CO
2 into clean fuels. The process involves production of synthetic gas or syngas (a mixture of hydrogen and carbon monoxide (CO)). With the help of the reverse water-gas shift (RWGS) reaction, CO
