“…The micropore volume of 0.069 cm 3 , determined using the Dubinin–Radushkevic method, plays a critical role in understanding the properties of teak seed biochar. Micropores are extremely small pores with dimensions in the nanometer range, typically less than 2 nm in diameter 54 . The presence of such micropores indicates the biochar's ability to accommodate and adsorb small molecules and ions effectively.…”

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.

“…Carbonbased materials for environmental applications may be classified into activated carbon, graphitic carbon (including carbon nanodots, carbon nanotubes, graphene, and fullerenes), biochar, carbon black, carbon-based nanomaterials (including carbon nanoparticles, carbon nanotubes, fullerenes, and graphene), and carbon composite. Activated carbon (amorphous carbon, including carbon black) is a type of carbon material that has a disordered atomic arrangement, which makes it non-crystalline, and is used in various applications, including adsorption [55][56][57], gas storage [58,59], biogas production [60,61], and catalyst support [62,63], due to its high reactivity. Activated carbon is a highly porous form of carbon that is produced by treating carbon-rich materials, such as coconut shells, wood, or coal, with steam or chemicals to create a network of small pores and a large surface area.…”

Biochar could be a brilliant additive supporting the anaerobic fermentation process. However, it should be taken into account that in some cases it could also be harmful to microorganisms responsible for biogas production. The negative impact of carbon materials could be a result of an overdose of biochar, high biochar pH, increased arsenic mobility in the methane fermentation solution caused by the carbon material, and low porosity of some carbon materials for microorganisms. Moreover, when biochar is affected by an anaerobic digest solution, it could reduce the biodiversity of microorganisms. The purpose of the article is not to reject the idea of biochar additives to increase the efficiency of biogas production, but to draw attention to the properties and ways of adding these materials that could reduce biogas production. These findings have practical relevance for organizations seeking to implement such systems in industrial or local-scale biogas plants and provide valuable insights for future research. Needless to say, this study will also support the implementation of biogas technologies and waste management in implementing the idea of a circular economy, further emphasizing the significance of the research.
