Formaldehyde degradation using Biofilter loaded with Compost, Vermiculite and Activated Carbon: Performance and Optimization
Air Quality
Formaldehyde is one of the typical indoor pollutants causing theprevalence of acute health issues among those residing in indoor environments. Biofiltrationis a commonly adopted technique to treat indoor air pollutants. In this investigation, a biofilter was fabricated and compactly filled with...
Evaluation of aqueous phase adsorption of Acid Brown on mesoporous activated carbon prepared from Azolla Pinnate seaweed
Water and Wastewater Treatment
A mesoporous activated carbon was produced from the Azolla Pinnate (AP) seaweed by two-step chemical activation technique using sulphuric acid as activating agent. The adsorption of Acid Brown (AB) from aqueous solutions is examined using the produced carbon (AP). The produced activated carbon...
Transforming waste into sustainable building materials: Properties and environmental impacts of Geopolymer concrete with recycled concrete aggregates
Solid Waste Management
Industrial by-products such as cementitious materials or aggregates have the potential to mitigate the adverse environmental effects associated with traditional cement manufacture. Geopolymer Concrete (GPC) is more eco-friendly than conventional concrete because it does not require cement. GPC with...
Conversion of the styrofoam waste into a high-capacity and recoverable adsorbent in the removing the toxic Pb(II) from water media
Water and Wastewater Treatment
The sequential nitration and magnetization of waste styrofoam to form a novel adsorbent has been investigated. The novelty of this study assigned approach lies in the introduction of an anionic surface on the styrofoam, enabling it to adsorb cationic Pb2+ ion, combined with its magnetic property...
Utilizing Manilkara zapota seed oil for biodiesel production and conducting an investigation into its properties and characteristics
Biowaste
Biodiesel can be derived from the oils of fruit seeds for powering diesel engines, and this study focuses on extracting biodiesel from Manilkara Zapota seeds, which are readily available and not intended for human consumption. The primary aim is to underscore the use of non-edible oils as a cost...
