“…Fibers in rind are useful because of their longer length and relatively better mechanical properties compared to fibers from inner pith which have wide applications but have inferior mechanical properties due to short lengths [64]. The stems of cane contain mainly pith (5%), fibers (73%), and the rind (22%) [65,66]. Pith and the outer rind are sources for fibers in sugarcane.…”

Sugar industries have huge potential to contribute to the sustainable energy transition through electricity generation and production of biofuels. Sugar-producing countries generate huge volumes of sugarcane bagasse as a byproduct of sugarcane production. In this study, the performance of an operating traditional sugar factory is analyzed for electricity generation and export potential. The study presents characteristics and energy potential of modern and traditional sugar factories. The challenges facing a traditional sugar mill are inefficient boilers, less efficient and back pressure steam turbines, and wasteful and inefficient use of steam turbine drives as prime movers instead of modern electric drives for the mills and cane knives. Others are the use of inefficient and energy intensive cane mill rollers instead of the diffusers which have low energy requirements. It was demonstrated that the cogeneration potential of sugar factory is quite significant but currently underutilized. Sugar factories can make significant contribution towards mitigation of greenhouse gas emission mitigation through supply of green electricity to the public grid. The study showed that the factory uses very old and inefficient boilers aged over 39 years which contributes to poor performance and low electricity generation capacity. Modernization is required to increase the generation and electricity export capacity through investment in new and modern high-pressure boilers, replacement of inefficient back pressure boilers (BPSB) with more efficient condensing extraction turbines (CEST), and reduction of factory steam consumption by electrification of mills and cane knife turbine drives among other measures. This study showed that the 3,000 TCD factory can invest in a 15 MW power plant based on current average factory performance indicators and more if the throughput and overall performance is close to design parameters.

“…Besides, economic allocation had only up to 3% change compared to energetic allocation. There are other possible uses of sugarcane lignocellulosic material (i.e., bagasse and straw), such as in the second-generation ethanol production (Junqueira et al, 2017), in thermochemical pathways for biofuel and bioenergy production (Bressanin et al, 2020(Bressanin et al, , 2021, and as animal feed (Souza et al, 2019;2021b), among others. Other LCA modeling approaches for handling residues and coproducts such as the consequential approach could also lead to interesting insights (Heimersson et al, 2019;Schaubroeck et al, 2021).…”

The implications of bioenergy deployment for sustainable development goals (SDGs) have been gaining importance worldwide, as bioenergy may contribute to other sustainability impacts besides climate change. Decarbonization of the energy sector can promote major co-benefits between Climate Action and other SDGs and lead to important tradeoffs. Life cycle assessment (LCA) methods have been proposed to monitor the SDGs as many of them are closely interconnected but often separately studied.A harmonized application of environmental and social LCA can reveal additional relevant aspects of SDGs. This work proposes an interpretation of combined environmental and socioeconomic LCA impacts by comparing the SDG impacts of electricity from sugarcane biomass with other technological options, which altogether represent 96% of the Brazilian electricity matrix. Our analysis indicates that sugarcane electricity has a higher SDGs score (58 points) compared to coal and oil electricity (42 and 47 points, respectively); however, it is lower than natural gas (78). Sugarcane SDG internal normalization related to the biosphere is very close to natural gas, varying only 3-4 points.On the Economy and Society SDG score, sugarcane electricity is also lower than natural gas. Key areas in sugarcane electricity production that need to be enhanced to better contribute to achieving the SDGs include improving its awareness levels, increasing wages and women representation on the workforce, and promoting measures to decrease work accidents as well as the use of fertilizers and pesticides. This approach may help design specific measures for different value chains for them to significantly contribute to the achievement of SDGs.

Performance Analysis and Development of an Export Cogeneration Plant For A 3000 Tcd Sugar Cane Factory

This study presents a feasibility of export electricity generation for a 3000 tons of Cane per day Crushing capacity factory which currently generates electricity for own consumption alone. The competitive sugar industry with high costs of production makes it necessary for diversification by sugar industry to increase its competitiveness. This will improve the sustainability of the cane sugar industry and the electricity grid by supply of green electricity. The factory and its cogeneration plant performances were examined for possible improvement and diversification into electricity export to the public grid. There is need to diversify operations by sugar industry which is facing a crisis as a result of sugar dumping and high costs of production. Other than diversification into ethanol production, export cogeneration has a potential to generate additional revenue streams for struggling industry. This study involves a performance analysis of an operating sugar factory to determine its electricity generation potential. Data was collected by observation, document analysis, interview, and questionnaire. The study showed that the cogeneration potential is significant and currently underutilized and can significantly contribute towards greenhouse gas emission mitigation from power generation and earn revenue for the struggling sugar factory making the factory more competitive. The plant uses old inefficient equipment of very low efficiency that contributes to the low performance. Steam generation is inefficient from 3 boilers all older than 30 years. Use of high-pressure high temperature boilers and an alternative fuel to bagasse as a secondary fuel will make export cogeneration more competitive and feasible. The study shows that at current design milling capacity and average performance, a continuous cogeneration plant with capacity of 15 MW is recommended.
