“…Studies indicated that pristine biochar often exhibits relatively lower sorption/immobilization efficiency than engineered/modified biochar (Li et al, 2019;Shaheen et al, 2019;Amen et al, 2020). Therefore, a chemical modification has been suggested in order to improve the sorption/immobilization capacity of biochar (Kwon et al, 2020;Panahi et al, 2020). Iron materials have high sorption ability for PTEs (Komarek et al, 2013;Qiao et al, 2019).…”

“…Biochar is typically made at a low temperature or slow pyrolysis (400-700 0 C) with a modest lean rate (less than 10 0 C minute -1 ) since carbon in biomass quickly decomposes into gas/ liquid products at high temperatures [11]. Biochar is created by a sequence of processes during the pyrolysis of feedstock, including isomerization, dehydration, decarboxylation, depolymerization, and charring [12]. The characteristics of bamboo biochar can be seen in Table 2, where the effect of the method in biochar production is very significant on the characteristics of the bamboo biochar produced such as pH, electrical conductivity (EC), liming potential, proximate analysis, cation exchange capacity (CEC), cation base (K, Ca, and Na), C inorganic and C organic.…”

One of the qualities of biochar is determined by the method in biochar production. The development of methods is carried out in traditional (Soil-Pit), conventional (Drum), and modern ways (Kon-Tiki). Thus, it is necessary to study the characteristics of the method in biochar production. The treatment units were allocated based on a Completely Randomized Design with three replication. The results showed that the characteristics of bamboo biochar based on the method of biochar production has a significant on the duration of firing and moisture of biochar and chemical properties of bamboo biochar on pH, EC, liming potential, proximate analysis, CEC, and cation bases (K, Ca and Na-exch), C Inorganic and C Organic. The best method of production of biochar bamboo is modern ways (Kon-Tiki) because it has effective time in the process production, high moisture, yield ratio compared to other methods, and less smoke so it can reduce air pollution.

“…Generally, biochar is characterized by low apparent density (0.30 to 0.45 g/cm 3 ), high surface area (200-400 m 2 /g) and high porosity (micro-, meso-and macropores) [20]. Several variables can be selected to ameliorate the biochar properties [21]. In general, as the temperature of the process increases, a greater percentage of gases is produced and the percentage of the solid fraction is reduced, with a similar effect on the surface functional groups of the biochar (C=O and C-H), which is also reduced [22].…”

In this age, a key target for enhancing the competitiveness of the chemical, environmental and biotechnology industries is to manufacture high-value products more efficiently and especially with significantly reduced environmental impact. Under this premise, the conversion of biomass waste to a high-value added product, biochar, is an interesting approach under the circular economy principles. Thus, the improvements in the biochar production and its new and innovative uses are hot points of interest, which are the focus of vast efforts of the scientific community. Biochar has been recognized as a material of great potential, and its use as an adsorbent is becoming a reliable strategy for the removal of pollutants of different streams, according to its high adsorption capacity and potential to eliminate recalcitrant compounds. In this review, a succinct overview of current actions developed to improve the adsorption capability of biochar, mainly of heavy metal and organic pollutants (dyes, pharmaceuticals and personal care products), is summarized and discussed, and the principal adsorption mechanisms are described. The feedstock and the production procedure are revealed as key factors that provide the appropriate physicochemical characteristics for the good performance of biochar as an adsorbent. In addition, the modification of the biochar by the different described approaches proved their feasibility and became a good strategy for the design of selective adsorbents. In the last part of this review, the novel prospects in the regeneration of the biochar are presented in order to achieve a clean technology for alleviating the water pollution challenge.
