In previous sections we have shown that the main contributor to the calculated environmental impacts (CC, AP, LU and WU) of CNC production with acid recycling is the use of process energy (for water evaporation in acid recycling and CNC drying). The overall impact values are relatively low for the case study of Quebec, mainly due to high percentage of renewable energy in the grid. To compare between different geographic regions, where CNC productions are set up or being set up, we conducted LCA for potential CNC61 production in four other regions: Alberta / Canada, Wisconsin / USA, Sweden and Tianjin/China, mainly focusing on the differences in impacts from energy generation.
