Energy Consumption Analysis in Production of bagasse and greenhouse gas emission (GHG) assessment from this product and Medium Density Fiberboard based on it

This study was performed to analyze the energy consumption in bagasse production as one of the byproducts from sugarcane and greenhouse gas emissions (GHG) amounts from bagasse production and its bagasse based Medium Density Fiberboard in Iran. Related data for this study was collected by direct interview and filling out questionnaires using company managers and staffs in Karoon Sugarcane Agro-Industrial Company and LooheSabz Jonoob bagasse based MDF Factory for the years 2016 to 2019. Greenhouse gas emissions were assessed by SimaPro software and energy consumptions amounts were calculated by direct and indirect energy consumptions and energy equivalents. Total energy consumptions for bagasse production were 2436.75 and 1368.74 MJ ha-1 in plant and ratoon farms, respectively. Water for irrigation, diesel fuel consumption and nitrogen fertilizer had the largest share of energy consumption in sugarcane production. The total amounts of greenhouse gas emissions for bagasse production were attained as 221.87 and 99.11 KgCO2eq ha-1 in plant and ratoon farms respectively. Diesel fuel consumption, agricultural machineries and nitrogen fertilizer in plant farms and diesel fuel, phosphate and nitrogen fertilizers in ratoon farms had the highest share of emissions, respectively. Furthermore, the amount of greenhouse gas emissions for bagasse based - MDF production was gained as 780.53 KgCO2eq m3-1. Electrical energy consumption, urea formaldehyde resin and natural gas had the main share in total GHG emissions in bagasse based -MDF production.
