Organic waste: a bioresource for production of novel cellulose nanocomposites

Grant holder: Dr A Chimphango

Institution: Stellenbosch University

Grant: CSIR/IU/WRIU/2016/009

Duration: 1 April 2016 to 31 March 2019

Status: Open

Project outline: The purpose of this study is to develop selective fractionation and modification methods for production of nano-products with simultaneous recovery of the by-products and co-products from grain and fruit processing residues. The research is proposed to explore efficient methods in particular, for fractionating grain and sub-tropical fruit residues to produce nanocellulose and use the by-products and co-products, thus hemicelluloses, lignin, pectin and polyphenols as agents for producing novel nanocellulose composites. The product spectrum of interest and benefits to be obtained from the biorefinery will be assessed from different combinations of isolation, separation, recovery and value addition methods.
