Abstract
Food industries generates a massive bone waste to overload the waste management per day. Alternative utilization of this type of waste is biochar production. It is not only the value-added utilization of this waste, but also concerning in the circular economy concept for environmentally sustainable development. Here, we characterized the physicochemical properties and potential of using the biochar from waste cow bone. We pyrolyzed the cow bone in three different temperatures, 400°C, 500°C, and 600°C. The results show that the pyrolysis temperature at 500°C was the best condition for biochar production influenced the surface area (115 m2/g), which was efficient in the wastewater treatment. The biochar was characterized in several physicochemical properties, including carbon content (8%), ash (2.5%), calcium carbonate, CaCO3 (7%), calcium sulfate (0.1%), and phosphate soluble (12%). Furthermore, the kinetics and thermodynamics of total chromium adsorption was significantly fitted with the Langmuir and pseudo-first-order kinetics models. From these respects, the biochar from cow bone could be a potential utilization of bone waste from food factories under the concept of sustainably circular economy in Thailand.
