Grant project deliverable

Beneficiation of forestry biomass waste streams

Grant holder: Dr B Sithole

Institution: CSIR

Grant: CSIR/IU/WRIU/2016/003

Duration: 1 April 2016 to 31 March 2019

Status: Complete

Project outline: This project is focused on the development of new value chains from saw mill waste (saw dust and wood chips) and sludge from pulp and paper mill operations. The idea is to extract valuable chemicals from saw dust and wood chips and nanocrystalline cellulose from the left over fibres and from fibres in the mill sludge. Success in the project will result in complete value chains for the industry with none of these wastes going to landfill.

» Briefing note: Opportunities for new biorefinery products from forestry, timber, pulp and paper wastes.
