A first comparison between systems B2 and B1 confirms that fossil energy use reduction benefits (as high as 1.15 GJ/t cane or 68 GJ/ha yr) could be achieved via an improvement in power generation potential from the excess bagasse combined with the utilization of the 50% cane trash. So for the whole 1 million ha sugar cane plantation in Thailand, the fossil energy savings amount to 68 PJ a year.
