“…Such optimization would render biochar commercialization on a large scale with multiple benefits such as soil health improvement, yield increase, GHG reduction, and climate change mitigation. Although a variety of recent reviews (Kavitha et al, 2018;El-Naggar et al, 2019;Sakhiya et al, 2020;Bolan et al, 2022;Abhishek et al, 2022;Amalina et al, 2022;Uday et al, 2022) have presented potential benefits of biochar applications across different fields. However, synthesis and current knowledge on biochar-soil-plant interactions is direly needed to elucidate the soil and plant responses to different biochars by considering the type of feedstock, pyrolysis temperature, and biochar application and management practices under different environmental conditions.…”

Biochars provide several agricultural and environmental benefits, such as soil health improvement, better crop growth and yield, carbon sequestration, decreasing greenhouse gas (GHGs) emissions, and regulation of nutrient dynamics. This review highlights the role of biochar in transforming the soil’s physiochemical and biological properties, and their impact on improving seed germination and seedling growth, altering crop physiological attributes, enhancing crop resistance against biotic and abiotic stresses, improving crop productivity, curtailing GHGs, and controlling nutrient leaching losses. However, the type of feedstock used, pyrolysis temperature, application rate and method, soil type and crop species largely influence the biochar performance under different environmental conditions. Application of biochars at low rates help to promote seed germination and seedling growth. Biochar modified the abiotic and microbial processes in the rhizosphere and increased nutrient mineralization and enhanced the nutrient availability for plant uptake. Hence, biochar enhanced the plant resistance against diseases, reduced the availability of heavy metals and improved the plant resilience against environmental stressors. By providing a comprehensive analysis about the variable impacts of biochars on soil physicochemical properties, plant growth, development and productivity and mitigating environmental problems, this review is quite valuable for developing an efficient soil and crop specific biochar with desired functionalities. It could be helpful in improving crop productivity, ensuring food security and better management of environment. Furthermore, this review identifies the knowledge gaps and suggests future outlooks for the commercialization of biochar applications on large-scale.

“…Recently, extensive research has been carried out to produce bio-oil and biochar from biomass through pyrolysis, showing that biofuels can be generated from first- and second-generation biomass, such as palm, 17 rice straw, 18 corn stover, 19 and sugarcane bagasse. 20 Yet, the massive use of first-generation biofuel feedstock may lead to competition between food and fuel, consequently increasing food prices.…”

“…The third factor is the microcrystallinity of graphite crystals, which increases with increasing reaction temperature. While biochar yield decreases with increasing pyrolysis temperature, the surface area tends to increase (Sakhiya et al 2021). Therefore, the choice of pyrolysis conditions can be based on the desired properties of the resulting biochar and the intended application.…”

Materials, fuels, upgrading, economy, and life cycle assessment of the pyrolysis of algal and lignocellulosic biomass: a review

Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral and circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review the pyrolysis of algal and lignocellulosic biomass with focus on pyrolysis products and mechanisms, oil upgrading, combining pyrolysis and anaerobic digestion, economy, and life cycle assessment. Products include oil, gas, and biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification and transesterification, hydrotreatment, steam reforming, and the use of supercritical fluids. We examined the economic viability in terms of profitability, internal rate of return, return on investment, carbon removal service, product pricing, and net present value. We also reviewed 20 recent studies of life cycle assessment. We found that the pyrolysis method highly influenced product yield, ranging from 9.07 to 40.59% for oil, from 10.1 to 41.25% for biochar, and from 11.93 to 28.16% for syngas. Feedstock type, pyrolytic temperature, heating rate, and reaction retention time were the main factors controlling the distribution of pyrolysis products. Pyrolysis mechanisms include bond breaking, cracking, polymerization and re-polymerization, and fragmentation. Biochar from residual forestry could sequester 2.74 tons of carbon dioxide equivalent per ton biochar when applied to the soil and has thus the potential to remove 0.2–2.75 gigatons of atmospheric carbon dioxide annually. The generation of biochar and bio-oil from the pyrolysis process is estimated to be economically feasible.
