Design of biochar from residual streams – influence of fuel and process parameters on biochar properties for water and soil applications
Biochar can be used in many applications, including water treatment and soil improvement. The properties of biochar are affected by the conditions during production. In this project, the influence on the properties of the biochar at different process conditions is investigated through the gasification of residual streams from both the forestry and agricultural sectors.
Making use of residual streams from industry and society are important for a sustainable society. By gasification, carbon recovered from residual streams can be upgraded to biochar and gas. Biochar can potentially be used for e.g. water treatment applications, soil amendment, and carbon storage in soil. The aim of this project is investigate suitable gasification condition for biochar production, perform characterisation of these biochar, and find a combination of methods for relevant characterisation of biochar physical properties with relevance for water treatment and soil amendment.
Valorisation of residual streams is an important key for building a sustainable society. Biochar can be used in many applications, and a char with high porosity, high specific surface area, and desired
surface chemistry can be suitable for e.g. wastewater treatment, water treatment and soil amendment. The overall aim of the project is to perform time-resolved investigation of suitable gasification condition for biochar production, that gives a biochar material with certain properties of relevance for water treatment and soil amendment.
