“…The major proportion of rice straw is burnt openly on the fields by farmers in India, because of lack of economically viable options for its management. 31 Open-field burning creates serious environmental and health issues. Pyrolysis is however an effective and suggestive ways to convert the rice straw biomass to biochar.…”

Rice straw and fly ash are the wastes produced in abundance which need immediate attention for their management. In the present study, the in situ pyrolysis of rice straw in presence of fly ash was carried out and the resultant composites were studied for adsorption of methylene blue (MB). Slow pyrolysis of rice straw in presence of fly ash is evaluated using thermogravimetric analysis (TGA) and Coats-Redfern equation for pseudo-first-order reaction kinetics, respectively. The activation energy (E a ) for the pyrolysis of rice straw was 41.75 kJ/mol which was lowered to 37.39 kJ/mol in presence of fly ash. Biochar fly ash composites BFA4 1-3 , BFA5 1-3 , and BFA6 1-3 were prepared at three 400 C, 500 C, and 600 C pyrolysis temperature, respectively, the subscript indicating three different ratios of rice straw and fly ash (1:3, 1:1, and 3:1 w/w ratio). The composites BF4-6 1-3 were neutral to alkaline in pH, due to the presence of basic oxide and carbonates minerals. BFA4-6 1-3 was studied for batch adsorption of MB and optimized for pH, dose, and initial concentration of adsorbate. The maximum MB adsorption capacity of 25.91 mg/g was reported for the composite BFA4 1 . MB adsorption efficiency (q e ) followed the trend BFA4 1-3 > BFA5 1-3 > BFA6 1-3 , which indicates a strong influence of biochar surface functional groups on dye adsorption, as reiterated by the multiple linear regression (MLR) analysis. Stripping of MB was achieved using methanol as a stripping agent for MB-adsorbed BFA4-6 1-3 with desorption efficiency of 7% to 11% in the first cycle and 23% to 100% in the second cycle.Thus, the biochar fly ash composite with optimum ion exchangeable functional organic moieties would be suitable for dye remediation and waste generated in the process could find application in soil amelioration.

“…Biochar, being a recalcitrant C-source, upon soil applications helps in slowing down native soil organic C (SOC) turnover and enhancing N fertilizer use efficiency, thus, resulting into reduction in GHGs emissions (Bhattacharyya et al, 2020). Biochar is useful in enriching SOC contents, enhancing beneficial biological activities, and increasing availability of nutrients (Bhattacharyya et al, 2021). It has been observed that its application to soil leads to improvement in soil fertility, improved soil water holding capacity, enhanced crop productivity, long-term betterment of soil health, soil C sequestration, pest and disease control, bioremediation of heavy metals in soil, degradation of dyes, and conversion of biowaste.…”

“…Agro-ecosystems can play vital roles, in one way, by ensuring the food security for billions of people and, on the other hand, being instrumental in efficient utilization of available resources, mitigating GHGs emissions and climate change (Bhattacharyya et al, 2020). In this context, overall agro-ecological functioning needs to ensure more sustainable ways of agriculture practices such as reduced usage of chemical fertilizers for enhancing food production without compromising the productivity and health of the soil, sustained increase in crop yield, boosting sequestration of carbon and depleting GHGs emanation (Khan et al, 2021;Bhattacharyya et al, 2021). The stress of feeding growing population, limited arable land, inefficient consumption of essential resources and amassing agro-residues has necessitated the need of a sustainable solution for the management of strained agricultural systems (Dhamodharan et al, 2020).…”

“…In China, approximately 0.7 billion tons of crop residues are produced annually (Yang et al 2018). Rice straw accounts for most of the crop residues and is commonly burned on site (Zeng et al 2007), which causes serious global warming potential (Cui et al 2017, Bhattacharyya et al 2021, Liu et al 2021a. One of the approaches to solve these residues is thermally converting these crop residues into biochar.…”

Biochar is considered as a soil amendment for enhancing crop productivity. However, limited information is available on the residual effect of biochar application on rice grain yield and yield attributes. In this study, a fixed field experiment was conducted in a double rice-cropping system from 2017 to 2019. The dynamics of rice grain yield and yield attributes were monitored in the six growing seasons with 0, 20, and 40 t/ha biochar application. The results showed that the averaged grain yields in the first four seasons were increased by 2.56−16.84% and 6.15−10.77% with 20 and 40 t/ha biochar application. The trend of increased grain yield in rice with biochar application during the first seasons was mainly attributable to an increase in total biomass, panicles per m2 and spikelets per panicle. Nonetheless, the grain yields in the sixth season were not influenced by biochar addition due to decreases in panicles per m2 and spikelets per panicle. Thus, it can be seen that the positive effects of biochar application on rice yield and yield attributes depend on the duration of biochar application.
