Char is the solid by-product of biomass gasification, which is rich in recalcitrant carbon and has a good carbon sequestration potential if amended in soil as gasification biochar (GB). This may benefit the overall carbon balance of the process while improving soil quality [1-3]. At the same time, previous studies have shown the eligibility of GB as a substrate for producer gas upgrading through tar conversion [4,5]. This application would benefit the economy and the environmental impact of gasification. In this work, the properties of fresh GB (as received) and spent GB (used in gas treatment tests) have been investigated to establish if the material may still be suitable for soil application after being used for the treatment of tar-rich producer gas.
