“…The gasification temperature was 950 ℃ and 1 bar. The "Gasmix" (mixer) was used to mix the three gases obtained, which were then fed to the "Scrubber" (VScrub) to separate the ash from the synthesis gas, using water (Marco et al, 2017;Mohammadi et al, 2020). To increase electricity yield, the combustion of the obtained gas was carried out at 900 ℃ and 1 bar ("Combustor" -RStoic).…”

“…The results show that the sugarcane cultivation and harvesting stage generate the most damaging environmental impacts, followed by electrical cogeneration, sugarcane transportation and sugar milling. Recently, Mohammadi et al (2020) evaluated the environmental impacts of energy production from sugarcane bagasse through combustion, gasification, and anaerobic digestion processes. The results showed that replacing natural gas with bagasse to produce energy in the sugar mills reduces GHG emissions.…”

“…The reality of sugarcane production in European countries is different from that in major production countries such as Brazil, India, the United States, and the Caribbean region [13][14][15][16]. In reality, production in Portugal, Spain, and Italy occurs in isolated regions, namely, in the island regions of Madeira, the Canaries, and Sicily, where sugarcane production was introduced as a subsistence culture to support colonization efforts centuries ago [17][18][19].…”

The sugarcane industry has assumed an increasingly important role at a global level, with countries such as Brazil and India dominating the field. However, this causes environmental problems, since the industry produces large amounts of waste, such as sugarcane bagasse. This by-product, which is energetically partially recovered in sugar mills and in the pulp and paper industry, can make a significant contribution to the general use of biomass energy, if the usual disadvantages associated with products with low density and a high moisture content are overcome. From this perspective, thermochemical conversion technologies, especially torrefaction, are assumed to be capable of improving the fuel properties of this material, making it more appealing for potential export and use in far-off destinations. In this work, sugarcane samples were acquired, and the process of obtaining bagasse was simulated. Subsequently, the bagasse was dried and heat-treated at 200 and 300 °C to simulate the over-drying and torrefaction process. Afterward, product characterization was performed, including thermogravimetric analysis, elemental analysis, calorimetry, and energy densification. The results showed significant improvements in the energy content, from 18.17 to 33.36 MJ·kg−1 from dried bagasse to torrefied bagasse at 300 °C, showing that despite high mass loss, there is potential for a future value added chain for this waste form, since the increment in energy density could enhance its transportation and use in locations far off the production site.

“…The annual production of sugarcane bagasse, a major feedstock resource during the sugarcane refining process (Sarker et al 2017), was estimated to be approximately 2.4 million tons in the Iranian sugarcane industry, Khuzestan province (Mohammadi et al 2020). Previous works have demonstrated that biochar derived from sugarcane bagasse is an important source of organic matter and a valuable amendment to ameliorate the chemical, physical and biological fertility of soils with low organic matter content (Azeem et al 2019;Bento et al 2019;Zafar-ul-Hye et al 2020;Rahman et al 2021).…”

Soil amendment with biochar alleviates the toxic effects of heavy metals on microbial functions in single-metal contaminated soils. Yet, it is unclear how biochar application would improve microbial activity and enzymatic activity in soils co-polluted with toxic metals. The present research aimed at determining the response of microbial and biochemical attributes to addition of sugarcane bagasse biochar (SCB) in cadmium (Cd)-lead (Pb) co-contaminated soils. SCBs (400 and 600 °C) decreased the available concentrations of Cd and Pb, increased organic carbon (OC) and dissolved organic carbon (DOC) contents in soil. The decrease of metal availability was greater with 600 °C SCB than with 400 °C SCB, and metal immobilization was greater for Cd (16%) than for Pb (12%) in co-spiked soils amended with low-temperature SCB. Biochar application improved microbial activity and biomass, and enzymatic activity in the soils co-spiked with metals, but these positive impacts of SCB were less pronounced in the co-spiked soils than in the single-spiked soils. SCB decreased the adverse impacts of heavy metals on soil properties largely through the enhanced labile C for microbial assimilation and partly through the immobilization of metals. Redundancy analysis further confirmed that soil OC was overwhelmingly the dominant driver of changes in the properties and quality of contaminated soils amended with SCB. The promotion of soil microbial quality by the low-temperature SCB was greater than by high-temperature SCB, due to its higher labile C fraction. Our findings showed that SCB at lower temperatures could be applied to metal co-polluted soils to mitigate the combined effects of metal stresses on microbial and biochemical functions.
