“…Despite few studies [734] which considered the environmental benefits of biochar derived from slow pyrolysis in alternative applications e.g. soil amendment, previous LCA research on pyrolysis modeled biochar as fuels bringing energy credits [711,734,754]. A significant research gap has emerged on the biochar acting as environmentally beneficial co-product in pyrolysis; GHG saving effects and environmental implications of pyrolysis configurations and feedstock on the CO2 adsorption functions of biochar need further investigation.…”

“…LCA is a well-known technique that is used to analyze the potential impact of the product on the environment throughout the cycle of its usage. One category of environmental impacts included in the commercial LCA software tools are human health, resource use, eutrophication, acidification and photo-oxidants formation [49].…”

The prospective utilization of bael shell (Aegle marmelos) as an agro-waste for the production of biochar was investigated along with its characterization and application for the abatement of hazardous aqueous Patent Blue (PB) dye solution. The sorptive removal of PB on bael shell biochar (BSB) was investigated under the following operational conditions: (pH, 2.7–10.4; biochar dosage, 2–12 g/L; and contact time, 0–60 min). The removal efficiency of PB by BSB in a batch adsorption experiment was 74% (pH 2.7 and 30 ± 5 °C). In addition, a clear relationship between the adsorption and pH of the solution was noticed and the proposed material recorded a maximum sorption capacity of 3.7 mg/g at a pH of 2.7. The adsorption of PB onto BSB was best explained by the pseudo-second order kinetic model (R2 = 0.972), thereby asserting the predominant role of chemisorption. The active role of multiple surface-active functionalities present on BSB during PB sorption was elucidated with the help of Freundlich isotherm (R2 = 0.968). Further, an adsorption mechanism was proposed by utilizing Fourier transform infrared spectroscopy (FTIR).

“…Emission factor calculations in the production of charcoal were done by other authors [31][32][33][34][35]. As an example, other LCA studies have evaluated the use of forest residues in charcoal production as a way to quantify sequestered carbon [36] and to evaluate the environmental performance of different carbonizers in the production of biochar [37].…”

New technologies and emissions controls have been developed for the production of charcoal, but are not widely used in the industry. The present study seeks to evaluate the potential environmental impact of these new technologies as compared to traditional ones. A Life Cycle Assessment (LCA) of Brazilian charcoal produced with different technologies without and with the combustion of the gases in burners or furnaces was carried out. The inclusion of furnaces for the combustion of gases reduces all categories of potential environmental impacts by approximately 90% in both a circular masonry kiln and a rectangular masonry kiln with gas combustion. In the process of producing charcoal (gate-to-gate system boundary), in terms of climate change, the rectangular masonry kiln with gas combustion was approximately 63% less impactful than the circular masonry kiln with gas combustion. In the gate-to-gate analysis, the rectangular masonry kiln with gas combustion presented the best performance when not considering NO 2 and SO 2 . Considering these emissions, there were changes in the impact categories of particulate matter emission and terrestrial acidification, and the circular masonry kiln with gas combustion presented better performance (for cradle-to-gate system boundary). The process in a rectangular masonry kiln without gas combustion presented a greater contribution to the categories of terrestrial impact ecotoxicity (98%), due to the emission of acetic acid especially.
