“…Hence, avid demand for fossil fuels has resulted in environmental challenges such as acid rain, biodiversity loss, soil pollution, global warming due to harmful greenhouse gas emissions from the combustion of fossil fuels and water pollution due to oil spillage ( Pant and Rai, 2021 ). The associated problems of fossil fuel usage have led to increased research, development and utilization of sustainable alternative fuels that are renewable and environmentally friendly ( Karuppasamy Vikraman et al., 2021 ; Rasam et al., 2022 ; S. Wang et al., 2022 ).…”

“…From the Figure 4A it was observed that change in enthalpy rose from 0.2 to 0.5 conversion, indicating that endothermicity increased from 0.2 to 0.5. According to Figures 2F and 4A, it was noticed that, activation energy ( E α ) and enthalpy change (∆ H ) maintained same trend against the conversion and when E α and ∆ H values were examined, there was little potential energy barrier (5 kJ mol −1 ) seen 51 . This smaller difference between E α and ∆ H represents the possibility of pyrolysis processes occurring, and the generation of activated complex is favored 11,23 …”

“…Criado's method was employed to find out reaction mechanism of T. chebula biomass pyrolysis at 10, 20, 35, and 55°C min −1 in the range of 0.1–0.8 conversion. In this study, power‐law (Pn), geometrical contraction (Rn), nucleation (An), diffusion (Dn), and order of reaction (Fn) models were studied 51 . Using thermal degradation data and E α obtained from the DFM method, the experimental master graphs were plotted as per Equation (29).…”

Non‐isothermal thermogravimetric tests of Terminalia chebula (Helikha) were conducted under inert N2 gas environment for temperatures (25–900°C) at heating rates of 10, 20, 35, and 55°C min−1. Kinetic triplet approximated employing five iso‐conversional methods namely, differential Friedman method (DFM), distributed activation method (DAEM), Ozawa–Flynn–Wall (OFW), Kissinger–Akahira–Sunose (KAS), and Starink (STK). Average values of activation energy (kJ mol−1) and frequency factor (min−1) calculated by the five models were 227.11, 2.98 × 1021 for DFM; 229.21, 4.63 × 1021 for KAS; 227.11, 3.81 × 1020 for OFW; 225.54, 1.15 × 1018 for STK; and 227.33, 3.02 × 1020 for DAEM respectively over the conversion range up to 0.8. In the kinetics study, correlation coefficient (R2) of greater than 0.97 is noticed in the conversion range of α = 0.1–0.8 for all models. From thermodynamic analysis, average values of ΔH (kJ mol−1), ΔG (kJ mol−1), and ΔS (kJ mol−1 K−1) for DAEM: 221.8, 179.69, and 0.065; for DFM: 236.40, 179.37, and 0.089; for KAS: 221.8, 179.69, and 0.065; for OFW: 220.22, 179.72, and 0.063; and for STK: 222.02, 179.68, and 0.066 were estimated to assess viability and reactivity of the process. Criado's master plots revealed that the data obtained from pyrolysis of selected biomass was followed a multistep reaction pathway.

Main conclusion This review discusses the Finger millet's rich nutritional profile, bioactive potential, and industrial applications, combined with its climate resilience, which make it a promising crop for enhancing food security and promoting sustainable agriculture. This review also highlights its significant potential to address malnutrition and mitigate climate change impacts. Abstract The emergence of Finger millet from “poor man’s staple food” to “a nutrient rich cereal” has encouraged the need to explore this crop at a wider scale. It is a highly significant crop due to its rich nutritional and bioactive profile, diverse biological activities, and promising industrial applications, along with the high climate resilience. This comprehensive review evaluates its nutritional composition by comparing favorably with other cereals and millets and emphasizing its potential to address malnutrition and enhance food security. Furthermore, it explores the phytochemical/bioactive potential and strategies to enhance their bioavailability followed biological activities of Finger millet by highlighting its various health-promoting properties. The review also discusses industrial potential of finger millet including its role in nutraceutical and functional food production, as well as bioenergy generation. In addition, role of Finger millet as a climate-resilient crop; specifically, the available genetic resources and identification of genes and quantitative trait loci (QTLs) associated with major stress tolerance traits have also been discussed. By providing a comprehensive synthesis of existing knowledge, this study offers valuable insights for researchers, policymakers, and stakeholders engaged in efforts to promote sustainable agriculture, enhance food and nutrition security, and mitigate the impacts of climate change.
