“…In the long run, this lowers greenhouse gas emissions by lessening the environmental solid burden. This ash has been used in various proportions with cement and brick to improve their mechanical properties and durability, preserving both the environmental and economic sustainability of the building materials [6]. Also, with this ash, a number of significant materials that are potential energy sources have been created, including zeolites, geopolymer, silica, briquette catalyst, and other items [6].…”

In the current study, two series of catalysts were synthesized and characterized by various physicochemical techniques. In the first series of catalysts, a chemical precipitation method was used for loading 1–20 wt. % ZrO2 on the surface of sugarcane bagasse fly ash (SCBFA) with the goal of finding out the optimal ZrO2 loading. In the second series, the 20% ZrO2/SCBFA composition was modified by (1–10 wt. %) SO42− by wet impregnation method. The acidity of these catalysts was determined through the dehydration of isopropyl alcohol and the chemisorption of pyridine and 2,6‐dimethyl pyridine. The catalytic efficiency for the dehydration of methanol to dimethyl ether (DME) in a fixed‐bed reactor at atmospheric pressure was investigated. A ~ 95% yield toward DME is maximized over the 10% SO42−/20% ZrO2/SCBFA catalyst at a reaction temperature of 400°C. Additionally, it maintained nearly the same efficiency over a 90‐h period and demonstrated outstanding long‐term stability. The specific surface area and the acidity are the most important factors responsible for enhancing the catalytic performance in this reaction. Our study reflects that SCBFA‐supported zirconia and that modified with SO42− are low‐cost, effective, eco‐friendly, and recyclable catalysts that are highly suited to apply for production of DME from methanol.

“…Bagasse fly ash (BFA) has some extraordinary properties, including adsorption for removal of dye, metals, and other contamination; an electrode for capacitive deionization; use in the construction industry as cement additives and substitute as cement; and preparation of briquettes, water polymers, and mesoporous silica. 13 The application of BFA in construction was comprised of oxides of various materials. 14 BFA were used to prepare pastes and mortars and increased the viscosities.…”

Composites were manufactured from glass fiber, bagasse fly ash, and epoxy matrix and examined their mechanical and physical properties. The percentages of bagasse fine ash, glass fiber, and matrix were designed at 10%, 15%, 20%, 25%, and 30% with 30% glass fiber and conducted density, flexural strength, hardness, absorption of water, and swelling properties of thickness. Composites were prepared by manual layering. ASTM standards were followed in preparing the samples. According to the results, the bagasse fine ash percentage variation was significant in the composite but had no linear effects on its hardness and flexural strength. A 20% bagasse fine ash composite had the highest flexural strength and hardness at 27.65 MPa and 52.86 HRA, respectively, which are significantly (>0.002) higher than composites of 30% bagasse fine ash, along with the highest density. This study measured water absorption and swelling of composite samples immersed in distilled water for 192 h. As the bagasse ash content increases, these values were linearly increased until saturation occurs.

“…The presence of small silica particles and char fines makes the recovery and use of this material challenging [10,11]. Therefore, SCBA is often disposed of in landfills as waste [12][13][14][15][16] and occupies large landfill spaces [17,18], resulting in both environmental and economic issues [19].…”

One of the byproducts of sugarcane bagasse combustion in sugarcane mills is sugarcane bagasse ash (SCBA), which contains up to ~40 mass% of organic matter. Currently, SCBA is partially used as a soil fertilizer. However, SCBA’s poor content of minerals, which are required by soils, restricts its use in soils, resulting in the disposal of large amounts of SCBA in landfills. Alternatively, SCBA has shown promise for some environmental applications such as wastewater treatment, but its use in gas cleaning deserves further study. The objective of this work was to assess the use of as-received SCBA to remove hydrogen sulfide (H2S) from biogas, thus, to add value to the ash. The experimental procedure consisted of passing biogas containing H2S through a column with SCBA and monitoring the H2S content inline by employing a gas chromatograph until the concentration of H2S, measured after the column, was ~10% of the original concentration. The breakthrough time of the SCBA adsorption curve was ~75% the breakthrough time observed with activated carbon, showing that SCBA could be a cheap alternative to commercial materials that are currently used for biogas scrubbing. This result could positively impact ethanol sugarcane mills that need to clean biogas produced from vinasses, as part of a strategy to integrate biogas production and cleaning operations using low-value residues (i.e., vinasses and ash). SCBA’s capacity for removing H2S from biogas results from the presence of K-compounds (e.g., K2SiO3 and K2Si2O5) on the ash’s surface and its relatively high porosity. Additionally, S-enriched SCBA (due to H2S retention) can expectedly be more beneficial to soils than directly adding the ash since S is an essential nutrient for the growth of plants.
