The world's first successful Desilication technology was developed and tested on semi pilot scale, achieving more than 80% desilication in bamboo and agro residues black liquors. A mill scale demo plant was erected and commissioned at Hindustan Newsprint Limited, in 1989.

2. Thermal Treatment of Black Liquor
Process of thermal depolymerization of black liquor to reduce viscosity & to attain high solids concentration was developed by CPPRI.
