“…Due to the unique structure of this carbon-based material, it has already seen use in carbon sequestration and wastewater treatment applications. Further consideration to this technology is given in terms of potential use for soil remediation in agriculture (Zama et al 2018), hipower battery (Saavedra et al 2018), and high-strength composite materials (Das et al 2015a(Das et al , 2016a applications. With current and prospective utilization of biochar increasing, it is inevitable that large-scale manufacturing demands will increase.…”

Biochars were produced from softwood chips (spruce-fir mix) and hemp stalk biomasses in an in-house-developed microwave pyrolysis reactor. A kilogram batch raw biomass mixed with 10 wt% microwave absorber was pyrolyzed at 60-min residence time. Microwave power levels were set at 2100, 2400, and 2700 W with optimum heating rates ranging 25-50 °C/min. The proximate analysis indicated a progressive gain in biochar carbon content with power level increase. Both biochars showed a H:C ratio of < 1.2 with a graphite-like structure, which is an important observation for their potential use as a filler in bio-composites structural strength increase. Fourier Transfer Infrared (FT-IR) spectra showed a major loss of functional groups as the power level increased. Brunauer-Emmett-Teller (BET) surface area and porosity distribution contained higher volume of smaller pores in the hemp biochar. The char hardness and Young's modulus, obtained via nanoindentation technique and load-depth curve analysis, indicated that hemp biochar possessed a higher Young's modulus and lower hardness than softwood chip biochar. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…The literature provides a great number of studies on different types of biochars used as sorbents for removal of various organic and inorganic contaminants, soil amendments and fertilizers, supplementary materials for composting and anaerobic digestion, additives for remediation of contaminated soil, etc. [10][11][12][13][14]. The most recent applications include using biochar as a potential hydroponic growth substrate [15], a biochar composite membrane or a wood polymer composite [16,17], a green roof substrate [18] or a microbial carrier [19].…”

Abstract. Pyrolysis of biomass residues from agriculture and food processing industry allows production of biochars with diverse physical and chemical properties for a wide range of applications in agriculture and environmental protection. Biochars produced from pelletized sunflower husks through slow pyrolysis in the range of temperatures (480-580°C) showed total carbon of 70.53%-81.96%, total nitrogen of 1.2%, alkaline pH (9.37-10.32), low surface area (0.93-2.91 m 2 g -1 ) and porosity of 13.23-15.43%. Higher pyrolysis temperatures resulted in lower biochar yields. With the increase in temperature the content of organic matter, nitrogen, Ca and Mg decreased whereas the increase in temperature resulted in higher contents of total carbon and phosphorus. Produced biochars showed potential for agricultural applications.

“…The near extinction of fossil fuels coupled with the urgent need to manage organic wastes and curb pollution necessitate an initiation of sustainable development where waste based renewable resources would be used for the production of power, fuels, construction materials, and chemicals (Das et al, 2015a;Srinivasan et al, 2015). The unique role of waste biomass on a sustainable future can be appreciated because biomass is the only renewable and/or waste based alternative for carbon based fuels and chemicals.…”
