In the present study, the torrefaction of sugarcane bagasse in both dry and chemical treatment in comparison with the physical, chemical, and thermal properties of raw bagasse was investigated. Thermochemical torrefaction was carried out by pretreatment of raw bagasse with dilute sulfuric acid. The torrefaction temperature was carried out at a carried temperature (220–280 °C) and a torrefaction period (30–120 min) in a packed bed reactor under an inert environment, whereas dry torrefaction was performed using the same treatment without the addition of a chemical to the raw bagasse. Chars produced by chemical torrefaction were found with improved properties of heating value, energy, and bulk density at 280 °C and 120 min. Increasing temperature resulting in high fixed carbon content apparently decreases moisture content and volatile matter. The mass yield and energy yield were found to be decreased with temperature and time. The carbon content of torrefied bagasse was increased with temperature and time, whereas, hydrogen and oxygen content decreased due to the devolatilization reactions.

In response to this concern, many public and private bodies globally have set ambitious sustainable development targets with the goal of reducing plastic waste. To assist in meeting these targets, the implementation of reusable packaging schemes has been suggested.
