“…Likewise, derivation of binding parameters for oxyanionic pollutants like arsenite (AsO 3 3– ) and arsenate (AsO 4 3– ) is important, as these anions can also bind to biochar, especially in case of a pH <PZC when the net surface charge is positive . This perspective of a MSM extended with the three-site NICA-Donnan model and binding parameters for protons, metals, and oxyanions as outlined above is also highly relevant for the potential use of biochar as a soil amendment in the context of improving important soil functions such as water and nutrient retention in support of soil fertility and agricultural production . In this context, trace metals like Cu and Zn are essential micronutrients for crop growth but can become toxic when present in excess.…”

“…6,7 Using biochar as a soil amendment in soil remediation operations to reduce environmental risks of polluted soils is more sustainable than conventional remediation techniques 8,9 because biochar application contributes, for example, to the improvement of important soil functions like carbon sequestration to mitigate global warming and water and nutrient retention in support of soil fertility and agricultural production. 10 Most biochars are produced from plant-based materials like straw and wood, 11,12 which are composed of polysaccharides (cellulose and hemicellulose) and polyphenols (lignin), 13 at a pyrolysis temperature usually varying between 300 and 600°C. 14 Differences in plant biomass composition and pyrolysis temperature influence biochar properties including their carbon content, aromaticity, porosity, surface area, and type and density of surface functional groups.…”

The charging behavior of biochars resulting from (de)protonation is important for assessing their potential as adsorbents for in situ immobilization of trace metals in polluted soils. Here, the pH-charge curves of 20 newly produced biochars were measured, whereas curves of 16 other biochars were collected from literature. All 36 biochars were produced from different plantbased materials at various pyrolysis temperatures. The pH-charging data were used to derive proton binding parameters for a novel three-site NICA-Donnan model, accounting for proton binding to carboxylic (site a1 ) and phenolic (site a2 ) acidic groups as well as to a basic (site b ) group. This model successfully described the proton binding behavior of the 36 biochars at different ionic strengths for the first time, by extending the classical two-site NICA model with a basic group in combination with an electrostatic Donnan model using a fixed volume of 0.1 L kg −1 . A set of generic proton binding parameters derived from the data resulted in a relative error of ∼6% for proton adsorption by all 36 biochars. Recommended parameters are Q a1 = 0.39 mol kg −1 , log K ̃a1 = 4.55, m a1 = 0.70, Q a2 = 0.59 mol kg −1 , log K ̃a2 = 8.10, m a2 = 0.80, Q b = 0.39 mol kg −1 , log K ̃b = 4.78, and m b = 0.76.

“…While the nitrogen content of control (0% biochar) and biochar applied manure had no signi cant variation (p = 0.53). The biochar application to the manure improved pH, ζ-potential, CEC by reducing the EC concentration which could be bene cial to improve the water and nutrient retention capacity and bene cial for plant growth [30,31]. The increase in nutrient content by adding biochar at different fractions was shown in Table 3.…”

Sustainable crop production supports food security by mitigating water and nutrient stress from manures by excessively drained water. Cow manure is a good nutrient resource to enhance soil fertility and plant growth but requires a suitable amender to reduce the nutrients loss by leaching. Worldwide more than 20400 metric tonnes of pistachios were consumed where roughly 30% of the weight of the nut is the shell and could be a good feedstock for biochar production. Therefore, this study aims to produce biochar from pistachio shell by pyrolysis process at three different temperatures 350 to 550°C and by the analysis of various properties towards agriculture, the biochar at 450 ˚C was amended with 0% (control), 2%, 4% and 8% to the manure for eggplant growth (Solanum melongena). Out of all fractions of biochar application, 2% biochar has virtuous performance to increase 5.63 ± 1.45 cm of plant height, 1.33 ± 4.79 cm leaf length and 1.90 ± 4.43 cm leaf width compared to the control. The leaf chlorophyl content and plant biomass were also significantly (p = 0.02) increased compared to the control condition. However, there is no statistical difference was noticed in stomatal conductance and water retention capacity (p > 0.11) due to greater plant growth. We concluded from this study, a lower fraction of biochar application with manure is beneficial to reduce nutrient leaching from the manure. Under the circular economy and frameworks of sustainability, pistachio shell biochar application as an amendment in crop production has been a high legislative focus on valorizing food waste.

Biochar (BC), a carbon‐dense substance created through the pyrolysis of organic biomass, has garnered considerable interest as a promising option for sustainable mitigation methods. A comprehensive examination of the diverse attributes of BC and its implications for addressing contemporary environmental issues while fostering sustainable practices is compiled in this review. The synthesis techniques and structural attributes of BC are scrutinized initially, emphasizing its remarkable features such as broad surface area, porosity, and active sites. These characteristics of BC are conducive to myriad environmental applications, including pollutant remediation, soil health enhancement, and carbon sequestration. Subsequently, this review delves into the mechanisms underlying BC's effectiveness in environmental remediation. BC exhibits augmented adsorption capacities, catalytic functionalities, and interactions with microorganisms, facilitating the removal of contaminants from different matrices of the environment. Recently, BC and their products such as nano‐BC have gained widespread recognition as a feasible option for sustainable carbon material. Fabrication, characterization, modification, and diverse applications of BC were also discussed in detail. Its integration into agriculture holds promise for enhancing soil organic matter, augmenting production, and mitigating gas emissions, thereby contributing to food security and climate change mitigation. In conclusion, BC and nano‐BC emerge as a promising avenue for addressing environmental challenges and advancing sustainable development objectives. However, further research is warranted to optimize synthesis methodologies, elucidate long‐term environmental implications, and facilitate scalable production for widespread adoption.
