Abstract: Biochar has been widely used in the agricultural industry as soil enhancer with the ability to help retain water and nutrients in soil as well as to sequester carbon. Biochar can be produced from different biomass which includes saw dust, hazelnut shells and food waste. By converting food waste into a useful product, negative environmental impacts would be mitigated through reduced landfill inputs and reduced greenhouse gas emissions.This study assesses the possibility of using food waste to produce biochar through pyrolysis and adding these biochar into cement mortar. Different percentage of biochar were being added into cement matrix along with a control batch to investigate the influence of biochar on the setting time, water absorption, strengths and sorptivity of cement mortar. The results showed that the presence of biochar has a positive influence on the various properties of cement mortar. When 2 wt% of food waste biochar was added, this led to an increase in compressive strength but the overall flexural strength decreased at a later age. The sorptivity and permeability of the mortar was also improved due to the high porosity and water retention capacity of carbon in biochar. The setting time of mortar was decreased with addition of biochar with 8 wt% addition giving the shortest timing.
