“…These high production volumes highlight the impact of this agroindustry, not only at the socioeconomic level but also in an environmental context. From a circular economy perspective, some concerns have arisen related to sugar production, the generation of by-products and waste, and the sustainable development of the sugarcane industry [ [2] , [3] , [4] ]. Although sugarcane has been regarded as one of the most significant and efficient sources of biomass for biofuels production (sugar-based ethanol) and electricity co-generation (mainly from bagasse) [ 5 ], interestingly, the sugarcane cluster has been characterized by maintaining a constant search for alternatives that promote the integral use of the different resources of this agroindustry [ 2 ].…”

“…A study from Kumari and Das (2016) shows that by implemented pre‐treatment process, sugarcane has potential to maximize the production of biohythane with 303 mL H 2 /g COD and 142 mL CH 4 /g COD. Sugarcane is also one of the most lignocellulosic biomasses feedstocks used in the production of biohythane which abundant the most in India after Brazil (Vandenberghe et al., 2022). Therefore, sugarcane bagasse (SCB) and water hyacinth (WH) are selected in this study on the basis of their availability in India.…”

Biohythane production via single‐stage anaerobic digestion (AD) is an effective way for sustainable energy recovery from lignocellulosic biomass. In this paper, biohythane was produced through the AD process from pineapple peel waste substrate using purely cultured Methanosarcina mazei with the enhancement of palm oil mill effluent (POME) sludge as the inoculum. This study focuses on the effects of the lignocellulosic pre‐treatment method, the addition of POME sludge into M. mazei culture medium as inoculum, and various operational conditions (food to microorganisms (F/M) ratios, temperature, pH) on gas production performances. The experimental results indicate that these parameters influenced the efficiency of biohythane production by producing the peak maximum biohythane production rate values (HPRmax) and (MPRmax), H2:CH4 = 1.93:0.67 L/L‐d, and biohythane yield (HY) and (MY), H2:CH4 = 1.18:0.55 mL/L‐substrate. This study demonstrates that biohythane gas (H2 + CH4 + CO2) production from pineapple waste can be accelerated by M. mazei only with the enhancement of POME sludge through single‐stage AD system under mesophilic batch process conditions.

“…With a global sugarcane production of 72.91 tons/ha, the top producers contribute to approximately 1.75 billion tons annually, Brazil being the main leader in the manufacture of ethanol sector . Brazil and other countries such as Pakistan are increasing sugarcane production, making the filter cake industrial output 2.7 million tons during 2022/2023. , An important environmental and economic concern is how to dispose of filter cake, since it represents an approximate production of 30 kg/ton of milled sugarcane. , Currently, most sugarcane waste (i.e., filter cake, straw, and bagasse) biomass is burned, unused, or discarded, and it is crucial to adopt innovative circular economy policies in the sugarcane industrial sector as a key strategy to reduce, reuse, and recycle these generated biowastes. , …”

Saccharum officinarum L. exploitation and processing result in different byproducts, such as filter cake (FC). This study aimed to establish the most suitable experimental conditions to obtain lipophilic bioactive compounds from FC industrial residues, considering their high efficiency, cost-effectiveness, extraction yield, composition, and physicochemical properties. Results indicated that the most appropriate methodology consisted of the pretreatment of the FC sample with H 2 SO 4 , followed by ethanolic extraction (B6 method), avoiding energy-consumption FC drying steps and providing ethanol recovery (approx. 90%). The obtained B6 extract yield was 9.59 ± 0.27 g/100 g of FC dry weight, and this methodology proved to be more efficient in obtaining fatty alcohols (20.28 ± 1.48 g/kg extract) and phytosterols (31.56 ± 0.18 g/kg extract) while maintaining lower total monosaccharide concentration (26.19 ± 1.82 mg/g extract). Furthermore, the geographically related multivariate analysis in wax composition and antioxidant activity was evaluated by comparing B6 waxes from Guariba (G) and Univalem (U), both provided by Brazil and collected in June 2020. Overall, the wax composition is affected, but the antioxidant activity is uncompromised, which indicates that the optimized wax extraction method can be applied to FC.
