PJ is an invasive plant species that poses significant environmental and socio-economic challenges in many regions. This...

As the production of biomass waste from agroindustry grows across the world, a large amount of agro-based ashes ends up in polluting land. India produced 405.4 million tones of sugarcane in 2019, with a capacity of 105.4 million tonnes of bagasse and 2.5 million tonnes of SBA. The utilization of...

Green sand moulding uses silica sand for metal casting. Silica sand mining and delivery to foundries destroy the ecosystem, making metal casting unsustainable. Due to increased sand-casting output and massive civil buildings in India, the silica sand supply is declining. The depletion and shortage...

The effectiveness of biochar as a soil conditioner is depended on the feedstock type and pyrolysis conditions as these two factors determine its physical and chemical properties. Wheat straw was heated at two temperatures: a) 2500C and b) 5000C for two time periods: i)20 min and ii) 60 min to...

One of the biggest environmental issues has been the use and disposal of traditional fossil-based plastic, which is not biodegradable and uses a lot of energy in its production. Poly lactic acid (PLA) has received a lot of attention as an environmentally friendly substitute due to the fact that it...

The wastes are in many forms consist of organic materials like human, medical, food, plastics, construction waste etc. many researchers are focused on the waste management to gives more importance to the environment. The bio degradable waste was used in this research with naturals fibers. The need...

Expansive soils pose a danger to the foundations of engineering structures due to their poor engineering properties. These soils are usually treated using mechanical techniques, and chemical stabilizers. However, the production of these chemicals is not friendly to the environment, thus a need to...

The locally available tamarind fruit shells (TFS) pre-treated with 1N H3PO4 was used to remove the hexavalent chromium (Cr6+) from aqueous phase. The investigation was done by using continuously mixed batch reactor (CMBR) under room temperature. Few preliminary investigations was undertaken to...

Unqualified treatment of the discharge of wastewater contains a large number of nitrogen and phosphorus and other nutrients, such wastewater into the water environment is easy to lead to eutrophication of water bodies, and cause harm to human health. In order to prepare a cost-effective, efficient...

Industrial production brings serious Cr(Ⅵ) pollution problems, so as to explore new treatment methods for Cr(Ⅵ), In this paper, modified montmorillonite was prepared by modifying montmorillonite with starch and lanthanum nitrate, and its adsorption mechanism and effect on Cr(Ⅵ) were explored. The...

Adsorption of heavy metal ions (Cr, Pb & Zn) using prosopis julyflora roots has been investigated by batch adsorption and fixed bed column process. The various properties of adsorbent were analysed and the FT-IR spectra & SEM studies of prosopis julyflora powder, before and after adsorption of metal...

Batch adsorption experiments have been conducted to investigate the adsorption properties of the calcined sugar scum powder for methylene blue (MB) and methyl orange (MO) as models for cationic and anionic dyes. The kinetic and equilibrium adsorption have been investigated to determine the...

One of the major challenges faced by researchers is to recycle industrial wastes in a manner that reduces their environmental impact in nature. An experimental study was carried out to determine the suitability of using chopped tire rubber as reinforcements in green and sustainable geopolymer...

In this study, the potential textile dye biosorption capacity of a low-cost biosorbent (P. animale) was tested as functions of pH, biosorbent type, initial dye concentration, temperature, contact time and biosorbent dosage at batch scale level. The optimal conditions are 2, dried biosorbent, 93.16...

In present work, a novel supported bucky paper (BP) membrane was fabricated and evaluated for humic acid (HA) removal from water. For better understanding the effect of operating variables, response surface methodology (RSM) was also applied. Three independent parameters namely TOC concentration (5...

Antioxidant defense mechanisms are crucial for plants to survive under stress conditions. We investigated the capacity of a wild fern species, Nephrolepis biserrata, growing in the vicinity of industrial land to accumulate heavy metals, and assessed its antioxidative response under metal stress. The...

This work is aimed to select the best synthetic polymers available in the market with high transmittance in the TiO 2 activation range that can be coated with the semiconductor and withstand the photocatalytic oxidation conditions. Among eleven commercial organic polymers with different additives...
