Aerobic composting is a well-known technique for converting the biodegradable fraction of solid waste into a soil amendment called humus. Previous research has demonstrated that several additives can affect the composting process by shortening its duration, enhancing the quality standards, etc. Biochar, derived from various biomass sources, is one of the most commonly used additives. The properties of biochar vary with the biomass used to prepare it. Coffee husk, waste material from the coffee industry, accumulates a large amount of biomass. Coffee husk can be easily converted to biochar, which will reduce the volume of husk that needs to be disposed of. Research on coffee husk biochar underlined its ability in adsorption, water retention, etc. However, the possibility of using coffee husk biochar in composting has not been addressed yet. This study focuses on the influence of biochar derived from coffee husk on the aerobic composting of food and kitchen waste. Additionally, coffee husk itself is used as an additive and compared with the control. The composting process is done for 45 days in an open vessel. Various dosages of biochar (1%, 2%, 3%, 5%, and 10% w/w), as well as husk (1%, 2%, 3%, 5%, and 10% w/w), are used to understand the parameter deviation. The appropriate dosage of biochar and coffee husk is determined with the help of basic compost quality parameters like pH, conductivity, moisture content, etc.
