“…The thermal decomposition temperatures were affected by biochar structure and composition. The results clearly show that the biochars from pyrolysis have increased carbon and reduced oxygen contents, as found in some recent studies (Sakulkit et al 2020;Shrivastava et al 2021;Sahoo et al 2021b). Several studies have reported that carbon-rich biochar has good potential for soil amendment and stabilizes or immobilizes heavy metals in the soil, and decreases concentrations of hazardous metals in plants, but such performance depends on the types of feedstock and the experimental conditions (Abdelhafez et al 2014;Rizwan et al 2019;Wang et al 2020).…”

This study investigated the characteristics of biochars derived from pyrolysis of rubberwood sawdust and sewage sludge, and co-pyrolysis of these feedstocks at the ratios of 50:50 and 75:25. All feedstocks were pyrolyzed at 550°C in slow pyrolysis with a moving bed pyrolysis reactor. Then, the investigated characteristics of biochar samples were determined and are reported. The rubberwood sawdust biochar (RWSB) had a higher in carbon content (86.70 wt%) and was lower in oxygen content (7.89 wt%), while sewage sludge biochar (SSB) had a higher ash content (65.61 w%) and a low carbon content (24.27 wt%). The weight losses of biochars were observed in TGA while the DTG graphs show degradation rate of biochar produced in pyrolysis specific conditions. RWSB had a lower content of Si, Fe, K, Na and P than SSB as observed by XRF. The pH of RWSB, SSB and the blends (50:50, 75:25) of biochars was in the range 8.41–10.02. High carbon content of the biochar confirms potential for its use in carbon sequestration. The large pore volumes and specific surface areas of biochars were found by SEM and BET. The available functional groups in biochars were C–O, C = C, and C–H as confirmed by FTIR. Water holding capacity (WHC) and water releasing ability (WRA) of RWSB, SSB, and the blends (50:50 and 75:25) of biochars were 1.01–3.08 (mL/g) and 1.19–52.42 (wt%), respectively. In this study, our results show that blending woody and non-woody based biochars can help address nonpoint source contaminants in environment. So, these all findings should develop as tune to parameters of thermal degradation of biomass and bio-biowaste with sustain and eco-friendly biochar production.

“…The BET surface area of the macroalgal biochar was significantly lower than that of biochar from pigeon pea stalk (16.90 to 261.78 m 2 g −1 ). 58 This could be attributed to the lower lignin content in macroalgal biomass than in terrestrial plant biomass. Having said that, the BET surface area from this study was comparable with the previous work of Iaccarino et al , 34 who observed that the surface area of biochar from Salicornia bigelovii was in the range 1.30–2.35 m 2 g −1 .…”

“…As C. cajan produces strong woody shoots that grow taller and branch profusely, its spindly stems are extensively utilized as a fuel for cooking in energy-short regions of Africa, including Kenya, Malawai and Tanzania, as well as India, Nepal and Sri Lanka (Mula and Saxena, 2010). The stems were also use to make the charcoal that was once used in gunpowder (Kanchan et al, 2013, Sahoo et al 2021. C. cajan is grown in Africa for its woods than its seeds (Mula and Saxena, 2010;Kanchan et al, 2013).…”

A two-year field trial on lac production on Cajanus cajan (L.) Millsp. was conducted on the research field of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh of India following randomized block design during 2019-20 and 2020-21. After harvest of C. cajan seeds and lac as cash crops, the left-over wood of C. cajan was evaluated for fuelwood (as an energy stove) for the small and marginal farm households. The mean dry weight of total fuelwood (including shoot+root) varied from 1196.67 to 1393.67 g plant-1 in pooled data. The estimated mean weight of total fuelwood (root+shoot) of C. cajan varied from 1447.98 to 1686.34 kg ha-1 in pooled mean of both the years. The value of total (shoot+root) dry fuelwood per plant varied from Rs. 7,239.85 to Rs. 8,431.70 in pooled mean of both the years. This total fuelwood can fulfill daily household requirement of fuelwood upto 3 years (891 to 1037 days) @ 4.06 kg day-1 household-1.
