PET pyrolysis: Kinetics of a ‐graphite
AbstractOne of the primary issues nowadays is plastic waste management, where the low recycling rates and accumulation of waste plastic show an exponentially increasing trend with urbanization. Especially, the concern is high with the PET waste generated from food packaging industries. Thus, new technologies are required for waste refining. Pyrolysis is one such technique that will restrict the emission possibilities obvious with the incineration and convert plastic into some value-added end products. However, large scale implementation of pyrolysis technology for plastic waste management requires a thorough understanding ...

Influence of water ‐methanol injection and turbocharging on the performance of a hydrogen‐fueled spark ignition engine
This article presents a study that compares the performance and emission characteristics of a four-stroke, four-cylinder spark ignition (SI) engine fueled by gasoline and neat hydrogen. The engine was equipped with turbocharging to optimize ignition timing for power boosting and vaporized water –methanol injection to reduce emissions. Engine tests were conducted at speeds ranging from 2000 to 6000 rpm, with a fixed intake pressure and varying quantities of hydrogen and spark advance timings. The study compared the results of non-turbocharged and turbocharged engines with water–methano l injection in terms of combustio...

Delineation of groundwater potential zones in Kotagarh block of Kandhamal District, Odisha through geospatial techniques
AbstractThe integrative approach of remote sensing and geographical information system (GIS) has been a very useful tool for the delineation of groundwater potential zones in any terrain. Various natural factors such as lithology, geomorphology, land use land cover, slope, drainage density, lineament density, etc. control the groundwater recharge and storage. Individual thematic layers have been developed through GIS assigning proper weightage based on storage capacity. The groundwater potential zones in the study region are divided into three classes such as poor, good, and exceptional. The aforesaid methodology has been ...

Modelling of air emissions from open burning of municipal waste in Ilorin Metropolis, North Central Nigeria
This study aims at evaluating the pollutants often emitted into the environment during the open burning of solid wastes using the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) model under three scenarios. The ground-level concentrations of pollutants emitted were compared with the statutory limits of the World Health Organization (WHO) at selected receptor locations. The predicted maximum concentrations from the model for PM2.5 were 4184, 8633, and 10,419 μg/m3 and for PM10 were 16,481, 20,915, and 23,114 μg/m3 for scenarios 1, 2, and 3, respectively. The WHO limits of PM2....

Utilization of iron scrap into copperas and rambutan (Nephelium lappaceum L.) peel extract into environmentally friendly iron nanoparticles for hexavalent chromium removal and its kinetics
In this study, INPs are made by using iron scrap waste into copperas which is then reacted with rambutan peel extract (RPE). The reaction between iron scrap and sulfuric acid until crystals are formed and then washed until blue-green crystals are formed. The resulting crystal is made into a solution and then reacted with RPE. After forming a black solution, it was dried by spray drying. The resulting black powder was characterized by UV-Vis Spectrophotometer, SEM-EDX, FTIR, and XRD. The results showed that iron scrap can be synthesized into copperas with a Fe content of 19.84 ± 0.15%. RPE has a total phenol content of ...

A study on the impacts of antibiotic pollution and its remediation
AbstractAntibiotics' ability to treat bacterial infections has long been seen as a pillar of modern medicine. Antibiotic abuse and widespread overuse, however, have resulted in unexpected consequences that call for significant adjustments in policy to be mitigated. High levels of antibiotic emissions from manufacturing facilities may help to develop new types of resistant bacteria. Such pollution is acknowledged by many scientists, business leaders, decision-makers, and other interested parties as an unneeded and intolerable risk to public health worldwide. Antibiotics are frequently produced by soil microorganisms. The ba...

Occurrence, persistence, and ecological risk of bisphenol A in surface water receiving raw leachate from a municipal solid waste open dump in Kerawalapitiya, Sri Lanka
AbstractBisphenol A (BPA) is an anthropogenic chemical compound utilized to manufacture a wide range of consumer products, such as polycarbonate, polyvinyl chloride (PVC), food packages, and thermal papers. Because of its extensive worldwide use, BPA is pervasive in the environment, negatively affecting aquatic life. Therefore, we studied the occurrence, persistence, and ecological risk of BPA in surface water receiving raw leachate from a municipal solid waste (MSW) open dump in Kerawalapitiya, Sri Lanka. Our findings corroborate that the BPA average concentrations in the canal network were 0.4 –42.6 µg/L during the w...

Biodegradation of oil palm empty fruit bunch during cultivation of Volvariella volvacea
AbstractBiodegradation of cellulose, lignin, and hemicellulose from oil palm empty fruit bunches (OPEFB) by straw mushroom (Volvariella volvacea) was investigated. The present research mainly focused on the effects of effective microorganism (EM) treatment (M) and composting duration of OPEFB (C) on straw mushroom production. Two main stages were involved in this research. The first stage was emphasized on theV. volvacea culture process while the second stage was to evaluate the chemical properties of the OPEFB. Zero percent EM solution increased the OPEFB decomposition rate significantly for cellulose and slightly for hem...

Degradation of synthetic azo dyes by Citrobacter freundii isolated from tannery effluent
AbstractScarcity of water is becoming a big issue. Most of the water is used in industrial sectors including pharmaceutical, food, textiles, leather, and cosmetics. Industrial effluent water is unable to treat and reuse due to their intricate nature. Effluent water contains synthetic azo dyes since they employ synthetic azo dyes as a major coloring agent. Existing approaches are ineffective in treating effluent containing synthetic azo dyes. Synthetic azo dyes containing effluent water can be treated biologically to overcome the drawbacks of physical and chemical processes. In this research work, novel organism was isolate...
