Lignin aids in production of valuable nanocomposites

It has been recently established how agricultural waste may have numerous valuable uses. A lignin-based nanocomposite has been developed by researchers at the Centre of Innovative and Applied Bio-processing, Punjab. It is possible that the product may have commercial value. According to microbial test outcomes, the produced lignin-bases nanomaterial can be utilized in the form of an additive in covering and packaging products in the long haul. It is important to note how Lignin is a complex organic polymer with an excess of polyphenols having antimicrobial characteristics. Lignin can commonly be extracted from every dry plant, including crop leftovers and trees’ woody bark.

Each year, a large amount of lignin is produced as post-harvest agro-biomass and in the factories of paper and pulp. All of the extracted lignin goes in the trash, mostly.

Meanwhile, the process of burning post-harvest biomass, for instance straw, is a norm that farmers go by but also something which paves way for serious pollution.

The chief researcher of the study, Dr. Jayeeta Bhaumik, stated how their intention was to take up the difficult task of changing agro-waste into value-added nanomaterials having antimicrobial characteristics. This not only decreases pollution, but also increases the income of the farmers.

The researchers of the study made use of green and reproducible methods, rather than use strong chemicals and increased temperatures to produce nanocomposite in order to acquire nanomaterials. It was a one-step procedure to use lignin as the only source for lessening, capping, and stabilizing the nano-agents.

The material was then exposed to numerous assessments in order to gauge its antimicrobial quality. It was concluded that the lignin-nanocomposite preserved lignin’s antimicrobial and antioxidant qualities.

The research team was composed of Sanjam Chandna, Yeddula Nikhileshwar Reddy, Neeraj Singh Thakur, and Ravneet Kaur. The study results were recently published in the ACS Biomaterials Science and Engineering journal.
