LAUSR

This study aimed to utilize food industry waste (i.e. banana (Musa paradisiaca L.) peel), as a raw material for making banana peel activated carbon (BPAC). The activated carbon-making process was conducted at varying temperatures (200, 400 and 600°C) and furnacing times (1, 2 and 3 hours). The purification function of the BPAC obtained from the optimization process was assessed with used cooking oil (UCO) from the food industry. The purified oil was tested for three quality parameters, the peroxide value, free fatty acid value and iodine value. The results of this testing showed that BPAC could slightly improve the quality of used cooking oil.
