Precipitation and valorisation of lignin in South African kraft mill black liquor - first stages: Poster

Abstract

Worldwide, the pulp and paper industry is in decline due to a number of factors such as high production costs, the growing utilization of electronic media that compete with print media and books, as well as pressure for the industry to be more environmentally sustainable. The aims objectives of the current project is to precipitate and characterize lignin form kraft black liquor with an attempts to obtain narrow molecular weight lignin that can further be valorised to encourage Biorefineries in South African pulping mills.
