“…In this context, this study aims to: evaluate the feasibility of converting rice husk biomass into a carbonaceous material suitable for use as a soil conditioner or fertilizer; compare characteristics of the biochar obtained with a commercial soil conditioner expanded perlite; contribute to a closed life cycle for RH biomass, responding to environmental, social, and economic aspects of sustainable development (Kappler et al, 2018;Souza et al, 2018;Souza et al, 2019).…”

“…This difference in SA of RH biochar samples between one temperature and another was also identified by Qin et al (2017) at temperatures of 300 °C, 400 °C, 500 °C, and 600 °C, with surface areas of 0.99 m² g -1 , 1.89 m² g -1 , 13.38 m² g -1 , and 152.4 m² g -1 , respectively. These authors attributed the increase in surface area at higher temperatures to a higher volatilization rate and, consequently, loss of organic compounds (Kappler et al, 2018;Crombie et al, 2013). The same behavior was observed between biochar samples and other types of biomasses, such as apple tree branches, which, at pyrolysis temperatures of 400 °C, 500 °C, and 600 °C, presented SA values of 11.9 m² g -1 , 58.6 m² g -1 , and 208.69 m² g -1 , respectively (Jindo, K. et al, 2014).…”

“…Its application in the sustainable management of soil and plants in the perspective of circular economy (De Corato et al, 2021) has also been studied. As an example, Kappler et al (2018) conducted a study with green coconut shells. The authors state that by ensuring a closed cycle, as proposed, there is a reduction in the use of fertilizers and pesticides, and, thus, a reduction of global warming.…”

“…In soils, lignin decomposes slowly because it has a complex chemical structure, making the natural process of decomposition of rice husk (RH) very slow. Therefore, it is common to see piles of rice husks exposed to the open air in rural areas (Kappler et al, 2018).…”

The increasing world population boosted the demand for basic needs such as energy, water, and food. In turn, agricultural production has increased, generating a large amount of agro-industrial waste every year. Globally, Brazil is the seventh-largest rice producer, and the State of Rio Grande do Sul is responsible for 70% of the rice production in Brazil. Rice husks are composed of organic compounds (cellulose, hemicellulose, lignin, and extractives) and inorganic elements that include potassium, calcium, magnesium, and sulfur. These inorganic elements are essential nutrients in the soil. Since natural degradation is slow due to the aromaticity of lignin, rice husk (RH) waste accumulates and poses an environmental threat, causing air and water pollution. In this context, in order to return the biochar to the soil, the properties of rice husk and rice husk biochar were evaluated. Parameters such as pH, true density, bulk density, porosity, identification of the composition and concentration of the elements, analysis of the functional groups, total carbon (TC), and cation exchange capacity (CEC) were performed on RH biochar samples. These samples were produced in a laboratory-scale pyrolysis rig, under a con-trolled atmosphere of Nitrogen (N), using three peak temperatures (350 °C, 450 °C, and 550 °C) and three soak times (30, 60, and 120 min).Based on the results obtained in the characterization analyses of the biochar, as well as the yield values found, it is concluded that the best pyrolysis temperature for the production of biochar from rice husks, for application in soils, is 550 °C.

“…Bio-char from the pyrolysis process has various applications including energy and fuel applications and environmental applications. Bio-char in its original form, or after conversion to activated carbon, can be utilized as adsorbent (for removal of different pollutants), and agricultural applications: it can be added to soil improve its fertility [39]. The obtained yields of the end products of biomass pyrolysis depend on the pyrolysis procedure and its conditions.…”

Microwave-Assisted Pyrolysis of Biomass Waste: A Mini Review

et al. 2020

The utilization of biomass waste as a raw material for renewable energy is a global concern. Pyrolysis is one of the thermal treatments for biomass wastes that results in the production of liquid, solid and gaseous products. Unfortunately, the complex structure of the biomass materials matrix needs elevated heating to convert these materials into useful products. Microwave heating is a promising alternative to conventional heating approaches. Recently, it has been widely used in pyrolysis due to easy operation and its high heating rate. This review tries to identify the microwave-assisted pyrolysis treatment process fundamentals and discusses various key operating parameters which have an effect on product yield. It was found that several operating parameters govern this process such as microwave power and the degree of temperature, microwave absorber addition and its concentration, initial moisture content, initial sweep gas flow rate/residence time. Moreover, this study highlighted the most attractive products of the microwave pyrolysis process. These products include synthesis gas, bio-char, and bio-oil. The benefits and challenges of microwave heating are discussed.
