Summary This study has dealt with the synthesis and characterization of biochars produced from three biomasses, viz. water hyacinth (whole plant and its components), yellow oleander, and sugarcane bagasse, and their comparative assessment for potential application in agronomy and energy production. The pyrolysis was carried out in a fixed batch reactor at 350°C and 550°C with a heating rate of 20°Cmin−1. Biochars were characterized for proximate and ultimate (elemental) analysis, and also using standard techniques (SEM, EDX, TGA, BET, XRD, and FTIR). Biochars produced at 550°C from all the feedstock had good properties (carbon content: 39.09‐80.74%, pH: 7.36‐10.42, calorific value: 16.98‐30.18 MJ kg−1, and ash content: 0.89%‐21.78%). Moreover, relatively low atomic ratios (H/C 0.25‐0.47 and O/C 0.15‐1.11) of all biochars indicated their potential as solid fuel. XRD results showed the presence of amorphous and crystalline structures, and minerals like sylivite, quartz, kalsilite, and tridymite in the biochar. Biochar produced from sugarcane bagasse at 550°C possessed the best properties: fixed carbon (77.42%), bulk density (0.13 kg/m3), brunauer–emmett–teller (BET) surface area (17.78 m2/g), pore size (12.86 nm), total pore volume (0.025 cm3/g), calorific value (30.18 MJ kg−1), ash content (1.16%), and moisture content (2.03%).

“…Similar results were reported for the biochars produced from sewage sludge and cow and pig manures. 48,49 The results in Table 4 indicated that bulk densities of biochars are in the range of 0.11 to 0.26 g cm −3 . This is consistent with previous literature.…”

“…Biochar can adsorb both NH4 + and NH3from soil solutions thereby reducing inorganic N solutions at least temporarily, but will be more concentrated to be utilized by plant [19]. Biochar is a process that reduces N content so biochar tends to have a high C/N ratio [5]. Another possibility is the occurrence of decomposition when fresh biochar is added to the soil [20], which can induce the net immobilization of inorganic N already present in the soil solution.…”

“…Conceptually, there are three mechanisms related to these benefits: (1) biochar will modify the soil directly through its intrinsic and compositional elements; (2) biochar provides an active surface that modifies the dynamics of soil nutrients or, if not, a catalyst that is useful for reactions in the soil; and (3) modifying soil characteristics in a beneficial way that affects root and/or nutrients growth and retains and acquires water [2]. However, the role of this biochar will be greatly influenced by its properties, and their properties are mainly influenced by their raw materials [3,4,5].…”

The goal of this research was to elucidate the characteristics of organic fraction of municipal solid waste or cow manure blend biochar produced in a batch-type carbonization reactor at range temperature, ranging from 300 to 350 degrees Celcius. The OFMSW composition to cow manure in feedstock were varied through five different levels (0, 25, 50, 75, 100 wt percent). The biochar properties of soil quality support were determined. The results of this study revealed that the pH was relatively stable. The EC, N total, and K available increased with increasing proportion of cow manure. Meanwhile, Corganic, P available, and ash, decreased with increase OFMSW proportion. The O/C and H/C ratio decreased with increasing proportion of OFMSW. The resulted composite biochar showed potential advantages such as stability and nutrient content.

Biochar is a product of thermal degradation of organic materials in the absence of air (pyrolysis). Slowpyrolyzed and biowaste-derived biochars show excellent adsorption properties. Studies on biochars produced from pine nut shells, sawdust, and cow dung have been carried out in Mongolia determining the technical characteristics and applying for improvement of soil quality. However, a thorough characterization of biochars is still in lack. In this study, we produced 10 biochars from animal bones and dungs, and firewoods and compared their characterization properties. Physico-chemical parameters of biochars such as moisture, ash, volatile matters, fixed carbons, pH, redox potential (pE), electrical conductivity (EC), total dissolved solids (TDS), cation exchange capacity (CEC), and base saturation were determined and SEM-EDX, FTIR, XRD, main elements, and trace metals analysis were obtained. Methylene blue and iodine absorption tests were carried out in terms of surface porosity. All biochars showed high electrical conductivity and base saturation indicating that they were rich in cations. The highest values of pH, EC, TDS, and CEC were found in biochar produced from sheep dung. Among bone chars, biochar produced from sheep spine bone showed the highest CEC. High Ca content in bone biochars resulted from the nature of the raw material. Biochars hardly contained trace metals. XRD analysis showed that the firewood biochar had amorphous, whereas the bone biochars and dungs had crystal structures. Biochars produced from animal and forestry biowastes have shown great values of adsorbent characteristics, thus the application of such biochars can simultaneously reduce waste and be an environmentally friendly valuable product.
