“…However, few studies exist on the creation and evaluation of biochar from invasive plant species. Studies that looked at biochar from invasive plant species either created a value‐added product (Liao et al, 2013) or used the charred material to reduce the mobility of contaminants in soil (Rajapaksha et al, 2014; Vithanage et al, 2014) and water (Ahmad et al, 2013; Zhang et al, 2015). There is scant research examining the use of biochar from invasive plant species in an agricultural context.…”

Biochar has been heralded for improving soil quality, sequestering C, and converting organic residues into value‐added amendments. Biochar research in agricultural settings has been primarily conducted on acidic soils, with few studies evaluating biochar effects on alkaline soils. Given the rise of small‐scale, sustainable farmers experimenting with biochar in South Florida's alkaline, carbonaceous soil, this study sought to assess biochar use in South Florida using an invasive plant species as a feedstock. Melaleuca quinquenervia (Cav.) S.T. Blake biomass was converted into biochar to measure how application at two rates, 2 and 5% (w/w), affects plant growth, soil macro‐ and micronutrients, and microbial gas flux (CO2) in a potted greenhouse experiment using Phaseolus vulgaris L. Plant growth was inhibited with biochar addition at the 2 and 5% rates. Dry shoot, pod weight, and pod length decreased significantly between treatments (P < 0.001). Significant reductions in plant‐available P, Ca, Mg, Cu, and Zn were observed in the 5% biochar soil postharvest (P < 0.05). Compared with the control, addition of biochar at 2 and 5% rates significantly reduced CO2 flux during the growing season, but not at harvest (P < 0.01). Our results indicate that those considering biochar application in South Florida's alkaline soil should be cautious in selecting feedstock and temperature for biochar production. Biochar can be produced at lower temperatures to decrease pH, but the concomitant increase in volatile matter (VM) is of concern. Although CO2 flux may have decreased, the deleterious impacts of M. quinquenervia biochar (pH = 8.12, VM = 26.5%) on P. vulgaris production should not be dismissed. Core Ideas South Florida invasive Melaleuca quinquenervia was used to make biochar. Increasing rates of M. quinquenervia biochar reduced bean growth in calcareous soil. A 5% (w/w) rate of M. quinquenervia biochar reduced available nutrients in soil. Melaleuca quinquenervia biochar addition reduced soil respiration compared with the control.

Biochar, as a soil amendment, provided a very cost-effective, convenient route to dispose organic residues. In the present study, the impact of adding biochar on the sorption, leaching and dissipation processes of bisphenol A (BPA) and 17α-ethynylestradiol (EE2) in soil was investigated. The biochar derived from corn stalks at 500 °C for 1.5 h was characterized by a highly aromatic and microporous structure with various functional groups on the surface. In the batch sorption studies, the application of 4 wt% biochar to soil significantly increased the solid-water distribution coefficients by 263% for BPA and by 298% for EE2 at the pollutant equilibrium concentration of 0.01 mg L(-1). In the leaching experiment, after five leaching periods, soil amended with 1 wt%, 2 wt% and 4 wt% biochar reduced the cumulative amount by 19%, 28% and 53% for BPA, 42%, 58% and 77% for EE2 compared to the biochar-free soil. Interestingly, during the 90 d incubation experiment, BPA and EE2 dissipations were not significantly affected by the added biochar, while remarkable decreases of CaCl2 extractable BPA and EE2 were observed. The overall results highlighted the distinctive potential of this biochar in reducing the mobility of BPA and EE2 in soil, meanwhile without attenuating the degradation of the two pollutants.

“…Biochar usually has a wide range of chemical compositions and surface properties depending on the biomass type, the heating rate, the residence time and the pyrolysis temperature [7]. Biochar is successfully utilized to mitigate climate change, improve soil fertility, and remove various contaminants in aqueous solutions as an alternative adsorbent, including heavy metals, excessive nutrients, and pharmaceuticals [8][9][10][11][12]. In comparison with an activated carbon, the manufacturing of biochar requires less energy and no pre-or post-activation processes, although it has a high adsorption ability and capacity [13].…”

Biochars as Potential Adsorbers of CH4, CO2 and H2S

Methane gas, as one of the major biogases, is a potential source of renewable energy for power production. Biochar can be readily used to purify biogas contaminants such as H 2 S and CO 2 . This study assessed the adsorption of CH 4 , H 2 S, and CO 2 onto four different types of biochars. The adsorption dynamics of biochars were investigated in a fixed-bed column, by determining the breakthrough curves and adsorption capacities of biochars. The physicochemical properties of biochars were considered to justify the adsorption performance. The results showed that CH 4 was not adsorbed well by the subjected biochars whereas CO 2 and H 2 S were successfully captured. The H 2 S and CO 2 breakthrough capacity were related to both the surface adsorption and chemical reaction. The adsorption capacity was in the following order: perilla > soybean stover > Korean oak > Japanese oak biochars. The simultaneous adsorption also leads to a competition of sorption sites. Biochars are a promising material for the biogas purification industry.
