The effect of pyrolysis temperature and feedstock on biochar agronomic properties

Aromaticity, polarity, and longevity of biochar derived from disposable bamboo chopsticks waste for environmental application

“…It is worth noting that the ash content in the DBC feedstock was lower than that in bamboo, based on Hernandez-Mena et al [ 42 ] (2.57%), Wang et al [ 37 ] (2.10%), and Sahoo et al [ 36 ] (1.58%). The FC content in woody biomass varies depending on plant type; therefore, the FC of DBC was 10.24% different from that of other wooden feedstocks, such as 15.2% for beech wood [ 49 ], 35% of tree bark (Pinus pinaster), and 19% of applewood [ 45 ] .…”

“…With respect to pyrolysis conditions, temperature, time, and heating rate determine the unique properties of different biochar [ 38 , 45 ]. However, many studies have noted that feedstock, temperature, and time are important factors that significantly affect the properties of biochar [ 36 , 46 , 47 ].…”

Systemic review for the use of biochar to mitigate soil degradation

“…The restoration of degraded soil by biochar depends on its specific properties, which are determined by the method in which biochar is produced. The effect of biochar was optimized by controlling pyrolysis temperature and feedstock type, and biochar with different characteristics was obtained (Das et al., 2021; Lataf et al., 2022; Tomczyk et al., 2020). Different thermochemical pathways can also be employed, such as slow, fast, vacuum, and microwave pyrolyses, and hydrothermal carbonization (Bruun et al., 2011; Carrier et al., 2011; Mašek et al., 2013).…”

“…At present, most studies on the improvement effect of biochar on soil only focus on the two factors of pyrolysis temperature and raw material type, which will limit the application conditions and reduce the effect of biochar (Lataf et al, 2022;Tomczyk et al, 2020). Some studies have verified that engineered biochar, using more treatment methods (change of pyrolysis mode, activation, combination of functional materials), has more prominent physical and chemical properties, less environmental risks and better remediation effects on soil than pristine biochar (Gusiatin & Rouhani, 2023;Mohit et al, 2024;Rostamian et al, 2015).…”

Influence of inherent minerals on metalworking fluids sludge pyrolysis: Products characterization and heavy metals behavior

“…Metalworking fluids sludge (MFS) is typically classified as hazardous solid waste, which is produced from metalworking processes involving cutting fluids [ 1 , 2 ]. The MFS composition is very complex, containing a mixture of hazardous substances, including heavy metals, toxic organic compounds, dioxins, biocides and additives, and other contaminants [ 3 ].…”
