Although deemed unsuitable for construction, Peat soils have remarkable applications in MFCs by generating electric power because of the microbial decomposition of rich organic matter. The demerits such as weak skeleton, high water content, acidic nature, and humus contamination of peat soil for civil engineering applications are considered merits in microbial fuel cell applications. Peat soil-based Microbial Fuel Cells (MFCs), the first of its kind among MFCs, are explored to generate electric power as high as 6 V when six MFCs connected in a series and lighted up an LED for 288 h. The performance of peat MFCs as a function of bamboo waste, fulvic acid, iron winding and surface area of the BC anode has been discussed in this work. The synergistic effect of organic decomposition by microbes and Fe complexation with humic substances (HS) has been detailed to be responsible for the cause of electric power in Peat MFCs. ATP measurement in peat soils after defined time periods confirmed the growth of microbial population, which successfully degraded the organic matter in MFCs. The characterization of BC anode and GAC cathode using FTIR, Raman, SEM with EDS, BET isotherm studies substantiated the structural modification and porous nature of the fresh and the used electrodes. The EIS study was performed to determine the dynamics of internal resistances due to the degradation kinetics in Peat MFCs. The cost effectiveness and the sustainability of Peat MFCs towards green technology are detailed in this paper.

Plaster board waste generated from industries, usually contains major proportion of calcium as calcium sulfate. In addition, fluoride is remarkably one among the constituents of this waste material which leaches off into the soil and aquatic environments and causes fluoride pollution. In order to simulate how the dumping of PBW causes fluoride contamination in soil and water sources, shaking and stirring based batch-mode leaching studies were conducted. These studies explored the leaching of fluoride as a function of particle size, agitation time, pH of the leaching solvent (distilled water), L/S (water: PBW) ratio, temperature and electrolytes. It was explored that 1 g of plaster board waste contains18.54 mg F per gram of PBP. High leaching of 3.72 mg F per liter was studied at pH 6.02 with Ca2+ and TDS contents of 1050 mg L−1 and1640 mg L−1 respectively. The influence of sodium electrolytes such as chloride, nitrate, hydrogen carbonate, carbonate, sulfate, borate, phosphate and acetate on the leaching of fluoride from PBW was studied. The influence of fluoride leaching by sodium phosphate recorded a high value of 12.75 mg L−1 with no detectable amount of calcium ions. The influence of eight electrolytic mixtures each containing five sodium electrolytes on fluoride leaching corroborated the highest leaching in mixtures containing phosphate followed by hydrogen carbonate/carbonate. Solutions of calcium and aluminium chloride and their mixture were used to measure the rate of leachable fluoride in solution. Furthermore, the fluoride leaching at different temperatures and acids was studied. Naturally occurring soils when blended with PBW were observed to immobilize fluoride and lessened the amount of leaching fluoride in water. Various characterization studies such as FTIR, Raman, FESEM (with EDS), XRD and XPS were carried out for PBW and its treated samples using different electrolytes. Fluoride leaching proportionate to the precipitation of carbonate and phosphate was recorded in the case of appropriate electrolyte and mixtures.

In the last decades, natural fire regimes have experienced significant alterations in terms of intensity, frequency and severity in fire prone regions of the world. Modelling forest fire susceptibility has been essential in identifying areas of high risk to minimize threats to natural resources, biodiversity and life. There have been significant improvements in forest fire susceptibility modelling over the past two decades 2001–2021. In this study, we conducted a systematic literature review of literature covering forest fire susceptibility modelling published during this period. The review provides insights on the main themes of forest fire susceptibility modelling research, the main base input factors used in models to map forest fire susceptibility, the main researchers, the areas where this type of research were implemented, technology and models used. It also highlights collaboration opportunities, and regions, such as Central America and Africa, where mapping of forest fire susceptibility is needed. We argue that such knowledge is crucial in order to identify critical factors and opportunities which can aid in improving factor selection and forest fire management.

The experiment conducted in this study was called the frozen–thawing test (FTT). In this test, two toughened glass blocks are used, such as the lower glass represents the bedrock and the upper glass the sliding body. A shallow tank was carved on the upper surface of the lower block. Water was injected to fill this tank, and then the upper block was positioned on top of the lower block. Both blocks were placed in a freezer at -20 °C for 48 hours. After several attempts, it was found that for a constant amount of water, the upper block started to slide at almost the same point of the thawing process.
