Carbon Footprint Analysis for Energy Improvement in Flour Milling Production

摘要

From the "cradle-to-gate" assessment of one ton of plain flour, wheat production is found to contribute most to the carbon footprint of plain flour with a percentage over 60%. In particular, the flour mill production, an energy-intensive lifecycle stage, accounted for approximately 30% of the final carbon footprint results - with the milling process resulting in 40% of the production emissions. Direct GHG emissions reduction strategies proposed include the purchased wheat from suppliers who demonstrate cleaner production and are of proximity. Alternatively, carbon footprint can be lowered indirectly through making the operations more energy efficient by improving the processes and equipment used.
