Fundamental Characterisation of Waste and Biomass for Char Production

Conversion of industrial waste materials to valuable resources would essentially take part in an ecologically sustainable future. There are still large amounts of undervalued biomass wastes generated from a diverse range of industries that are disposed in landfields. They have potential to produce valuable materials and fuels, such as charcoal, bio-oils and bio-gas through thermal upgrading. In order to enhance the efficiency of the thermal upgrading process, comprehensive characterisation of the raw biomass materials is essential. We have developed a novel thermal characterisation method that utilises computer aided thermal analysis incorporated with a gas analyser. The method was applied on two biomass materials, wood sawdust and bagasse. The paper discusses the results obtained with the novel thermal characterisation technique.
