“…The second way shows the biochar route from the pyrolysis process [9,18]. Biochar can be used to obtain syngas and used in combustion engines [89]. It has applications as a solid biofuel as well as for energy conversion and storage, such as hydrogen production and storage [90], supercapacitor electrodes [91], and lithium/sodium ion batteries [92].…”

Sugarcane has primarily been used for sugar and ethanol production. It creates large quantities of residual lignocellulosic biomass such as sugarcane bagasse, leaves, tops, and vinasse. Biomass is a sustainable prospect for biorefineries aiming to optimize production processes. We detail recent research developments in recycling sugarcane, including energy generation and pyrolysis to obtain biofuels, for example. To produce biochar, the energy cost of operating at high temperatures and large-scale production remain as obstacles. The energy generation prospects can be enhanced by pellet production; however, it requires an improvement in quality control for long-term storage or long-distance transportation. In civil construction, the materials still need to prove their long-term efficiency and reliability. Related to adsorbent materials, the use of sugarcane bagasse has the advantage of being low-cost and environmentally friendly. Nevertheless, the extraction, functionalization, and modification of cellulose fibers, to improve their adsorption properties or even mode of operation, still challenges. The synthesis of nanostructures is still lacking high yields and the ability to scale up. Finally, controlling dispersion and orientation and avoiding fiber agglomeration could improve the mechanical response of composites using sugarcane bagasse. The different possibilities for using sugarcane and its residues reinforce the importance of this material for the industry and the global economy. Thus, the present work addresses current challenges and perspectives of different industrial processes involving sugarcane aiming to support future research on waste-derived subjects.

“…However, limited research has focused on their potential for phenol removal from wastewater. Furthermore, there are some limitations on using agricultural residue as an adsorbent for phenol uptake from water, such as its requirement for pre-treatment before use to remove impurities and ensure optimal adsorption capacity [ [22] , [23] , [24] ]. While treatment of the biosorbents with chemicals can potentially enhance their adsorption capacity and efficiency, it may result in the production of even more dangerous by-products.…”

The importance of carbonizing teak seed waste lies in unlocking its untapped potential for sustainable resource transformation while achieving waste management and converting the waste to more valuable products. This study investigates the production and characterization of teak‐seed biochar employing a top‐lit updraft reactor. The process parameters include a carbonization time of 2 h and a peak temperature of 379 °C, resulting in a substantial yield of 42%. Elemental analysis reveals the biochar's composition, consisting of 77.20% carbon and 18.79% potassium, positioning it as a valuable resource with versatile applications. The Fourier transform infrared (FTIR) analysis showcases a rich variety of functional groups within the biochar, including alcohols, carboxylic and phenolic groups, amides, and various hydrocarbon structures, signifying its multifaceted potential for applications like the adsorption of aqueous pollutants, soil stabilization, and enhanced ion‐exchange capacity. Textural assessments emphasize its noteworthy surface area (Brunauer, Emmett, and Teller (BET) analysis: 190.05 m2g−1; Langmuir: 1664.35 m2g−1), micropore volume (0.069 cm3g−1), and total pore volume (0.097 cm3/g−1), primarily characterized by mesoporous attributes (pore diameter: 2.153 nm), rendering it suitable for various applications. Scanning electron microscopy (SEM) analysis of surface morphology reveals a rough texture embellished with various‐sized and shaped particles, distinguished by their silvery, shiny appearance, which is attributed to the biochar's elemental composition, particularly the presence of potassium. These findings underline the promising potential of teak seed biochar across multiple applications, including agriculture, wastewater treatment, and environmental remediation.
