The demand for biochar has increased over time due to its wide range of applications in various industries. Biochar, which is the solid product of the thermochemical conversion of biomass, has been synthesized using different reactor‐based technologies. One such technology is top‐lit updraft (TLUD) technology. This study is a review of published literature that discusses trends in the utilization of the TLUD technology, focusing on biochar production. This study also evaluated the principles of TLUD technology. The properties and applications of TLUD‐based biochar were also discussed. In comparison with other technologies, TLUD technology is characterized by higher thermal efficiency, simplicity of starting the fuel, low smoke emission, and high biochar yield. It was observed that the use of TLUD technology resulted in the production of high‐quality biochar with a variety of characteristics, which has been utilized as an adsorbent for wastewater treatment, in the agricultural sector to increase soil nutrients, and as a solid fuel. The concept of semi‐batch‐fed TLUD technology was also introduced in this study to enhance the efficiency and output of the batch‐fed TLUD configuration that has been in use. Some knowledge gaps in the study could be addressed by future studies on the use of this technology.

“…The wastes from these activities were examined at certain temperatures for the purpose of biochar production. Studies conducted in this context investigated the following: citrus peels at 300 to 700 °C (Selvarajoo et al 2022), peel, leaf, stem, and empty fruit bunches at 400 to 700 °C during palm oil production (Azman et al 2022), cassava peels at 338 °C (Odeyemi et al 2023), and the combined use of food waste and low-density polyethylene garbage bags at 500 °C (Neha and Remya 2023). Experimental results yielded significant knowledge regarding the reusability of wastes.…”

In agriculture-producing countries, pruning waste is obtained from fruit-bearing trees during the fruit-growing process. The present study aims to determine the potential of biochar of pruning wastes, obtained as a result of agricultural activities that have economic value. To the best of the author’s knowledge, no study has been conducted in Turkey to make a regional estimation of the biochar potential of pruning wastes. Biochar produced from waste provides the advantage of use in various fields, such as soil remediation and water and wastewater treatment. In this study, data on the number of trees bearing fruit (almond, apple, apricot, cherry, peach, pear, plum, and sour cherry) from the Turkish Statistical Institute were used based on the equations specified. First, the amount of pruning waste, then the usable pruning waste, and finally their biochar potential were calculated. It was estimated that the apple tree had the highest total biochar potential (41.5 thousand tons/year). Regarding the regions, the highest biochar potential was in the Central Anatolia Region for the apple tree (19.3 thousand tons), followed by the Eastern Anatolia Region for the apricot tree (13.6 thousand tons). The total biochar potential of pruning wastes from fruit-bearing trees in Turkey was estimated at 175 thousand tons for the year 2021.

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.
