# Palanisamy Thanikaivelan

Palanisamy Thanikaivelan is a leather technologist and material scientist. He joined the Central Leather Research Institute in Chennai, India in 2002 and currently working as the Chief Scientist. In 2006, he won the Young Scientist and Young Engineer Awards from Council of Scientific and Industrial Research and Indian National Academy of Engineering for his work on innovative and cleaner zero discharge tanning methods. He is a Young Associate of the Indian Academy of Sciences and Indian National Academy of Engineering.

## Education and career

Palanisamy Thanikaivelan earned his PhD from the Anna University while working at the Central Leather Research Institute in 2003. He founded the Advanced Materials lab at the institution in 2016.

## Research

Palanisamy Thanikaivelan conducts research in the area of cleaner leather processing and emerged as a significant contributor in the interdisciplinary area of advanced materials science.
His technological contributions to the leather industry by way of Do-Ecology solutions developed on first principles are widely appreciated. He found that complete transformation of chemical to biocatalytic processing is feasible thereby allowing the integration of narrow pH chrome tanning methodologies. He designed new synthetic protocols for self-doped carbon nanostructures from collagen wastes with potential applications in energy engineering. He aims to develop high value products from raw hide trimmings and shaving dust which are posing problems as solid wastes in leather sector.
He was part of the team of scientists who patented the process for game-changing waterless chrome tanning technology. This process was patented in 2016 in India and other leather making nations. The waterless chrome tanning technology is a paradigm shift adopted in at least 180 tanneries in the country as an industrial practice and also in a tannery in Egypt.
His important contribution in recent years was the development of path-breaking technologies on “Leather-like materials from agro-wastes”, which are transferred to two start-up companies.
