“…[71]. Da Silva et al [59] evidenced similar results when developing activated carbon from pineapple crown wastes. Van et al [72], also observed a distinctive peak weel indexed, indicating the presence of an amorphous structure with a high degree of graphite crystallization when utilizing activated carbon derived from coconut shells loaded by silver nanoparticles for methylene blue sorption.…”

“…In the activated carbon spectrum (BFAC), it was remarkable the disappearance of the -OH vibration band (3500-3200 cm − 1 ). According to Da Silva et al [59], this shows that the pyrolysis process removed the oxygen, and its aromatic structures were broken down to become a carbon-rich solid material. Furthermore, a reduction in the intensity of peaks associated with other functional groups was observed, indicating the breakdown of the complex lignocellulosic matrix into simpler compounds.…”

“…For the BFAC, the peaks corresponding to hemicellulose, cellulose, and lignin degradation disappear, as observed in the DTG curve, indicating that there is no organic matter in the sample because it starts its decomposition/degradation easily, with an active decomposition zone between 180 and 600°C. It is known that the temperature pyrolysis region (180-400°C) associates with the decomposition of easilydegradable compounds like carbohydrates, while the high-temperature region (400-600°C) corresponds to the decomposition of compounds with high molecular weight like aromatic compounds and polyphenols [59].…”

“…Moreover, these adsorbents are the most appreciated due to their low cost, simplicity, biodegradability, and environmental compatibility [23]. Different agricultural residues are used as adsorbents to remove pollutants, including dyes such as pineapple crown [20], palm tree [24], rice hull [25], teak bark [26], Eichhornia crassipes [27].…”

Activated carbon (AC) produced from agro-industrial waste is an interesting adsorbent in water purification and effluent treatment processes. In this work, activated biochar (BFAC) from banana peel waste (BPF) was prepared by chemical activation (NaOH) followed by pyrolysis at 600 °C to remove methylene blue (MB) from wastewater. BFAC was characterized by TGA, XRD, SEM, and FTIR techniques. The influence of dye concentration (10, 25, 50, 100, 250, and 500 mg L−1) and zero point charge (ZPC) were investigated. Besides, a Life Cycle Assessment (LCA) was conducted to evaluate and analyze the environmental effects of the developed process. BFAC presented a well-developed pore structure with a predominance of mesopores and macropores, influencing the MB removal capacity. The highest efficiency for dye removal was 62 % after 10 min to an initial concentration of 50 mg.L-1. Temkin, Langmuir, and Freundlich, isotherm models defined the adsorption isotherms well. The Langmuir model represented the best fit of experimental data for BFAC with a maximum adsorption capacity of 417 mg g−1. Regarding LCA, a prospective approach at the early stage of development was conducted to orient the transition from laboratory to industrial scale, aiming at providing a competitive CO2-based technological route. The proposed scenarios suggest that this route is promising either from the life cycle assessment or the circular economy perspective. Thus, BFAC can be considered as an adsorbent of great practical application for post-treatment of wastewater effluents aiming to remove contaminants.

Soybean residue has caused pollution to the environment due to high output. Herein, in order to reutilization soybean residue, a novel soybean hulls residue based hierarchically porous carbon was prepared by one‐step carbonization‐activation, and its structure and micromorphology were characterized by SEM, FT‐IR, Raman, TEM, BET and XPS. Based on results of characterization, which illustrated typical hierarchically pore structure with pore sizes are 1000 nm, 300 nm and 1.4 nm. The specific surface area and total pore volume were corresponded to 1455.41 m2/g and 0.731 cm3/g, respectively. And the pore‐forming mechanism was discussed in raw materials is a pyrolysis process. Furthermore, it was found that adsorption capacity of dye could got to 625 mg/g in 30 min when the adsorbent was 0.05 g. In summary, the soybean hulls residue based hierarchically pore material with large surface area and rich in pore structure, which will exhibit excellent performance towards wastewater treatment.
