Bengaluru: Agricultural waste can find many useful applications. Researchers at the Mohali-based Centre of Innovative and Applied Bioprocessing (CIAB) have developed a lignin-based nanocomposite which could potentially have commercial value. Microbial test results indicate that, in the long run, the lignin-based nanomaterial can act as additive in coating and packaging materials.
Lignin is a complex organic polymer rich in polyphenols with antimicrobial qualities. It is found in almost all dry plants including crop residues and the woody bark of trees. Abundant quantities of lignin are generated as post-harvest agro-biomass and in paper and pulp industries every year, which often go waste.
