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...

This study utilized a series of experimental tests, including the Atterberg limit, standard Proctor, permeability, and direct shear tests. Three composites were investigated: 85% fly ash-10% bentonite (V1), 90% fly ash-5% bentonite (V2), and 95% fly ash-0% bentonite (V3). All composites contained 5%...

Excessive use of fossil fuels results in the rapid depletion of non-renewable fossil energy resources, a rise in fuel cost, and an uncontrolled emission of greenhouse gases which causes a severe threat to the environment. Bio-fuels are being scrutinized as substitutes for current high-pollutant...

Pectin extraction from various fruits and its application in food products have been debatable issues for ages. We conducted our research on the biomass wastes of the food industry, primarily banana (Musa Acuminata) peels, in order to develop a modified procedure for the effective extraction of this...

Rapid urbanization has given us many benefits in terms of giving us a better standard of life, but it sure has brought a lot of problems with it. Solid waste management is a major issue that has been in the forefront of the issues caused by urbanization. It has brought a lot of domains together...

Dewatered sludge is the main by-product from wastewater treatment and it contains various types of hazardous substances which can cause environmental pollution. The alternative utilization of sludge waste is for covering the landfill or as liner for the landfill. Landfill cover is a critical...

Plastic waste is harmful to the environment due to its long-term decomposition process. Plastic waste is made out of hydrocarbon polymers, its chain bonds do not naturally decompose physically, chemically, or biologically. The plastic waste generated in Indonesia reaches up to 175,000 tons per day...

Kalamata’s decentralized waste management and composting scheme is a successful demonstration of the capacity of a municipality to manage its Municipal Solid Wastes (MSW) by adopting methodologies that can be supported by small scale mobile equipment. According to the revised legislation, Join...

Severe energy crisis and vilest economic conditions in Pakistan demand the country’s energy portfolio to be revised with increased reliance on indigenous energy resources. The perspective of utilization of abundantly available biomass waste fractions as a fuel alone and their co-combustion with two...

The coronavirus (COVID-19) is a threat to public health and caused several social, environmental, and economic problems. During the lockdown in different countries, waste generation has been significantly increased due to the high consumption of packaged food and increase the order of food via...

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...

Urbanization, industrialization and economic growth have considerable challenged the orientation of waste management policies and practices. Intrinsically, major concerns appear in urban environments, as they receive increased volumes of waste, which in turn pose threats for the environment and...

Many eutrophic lakes contain rapidly growing hydrophytes. Overgrown biomass is usually me-chanically harvested and thrown away, leading to resource waste and secondary environmental pollution. Microbial degradation is an economically and environmentally friendly approach for managing hydrophytic...

In this research, the selective leaching of copper from waste printed circuit boards (PCBs) using glycine as a complexing agent was investigated. PCBs were pulverized and sieved, which allowed obtaining a PCBs powder of particle size fraction ≤ 1mm. The PCBs powder has been characterized by several...

Cellular Lightweight Concrete (CLC) also known as Foamed concrete is one of the most significant type of concrete used for construction purposes due to its various advantages and usages over traditionally produced concrete. The rapid urbanization has led to the enormous increase in wastes being...

In the recent era, utmost attention is paid towards exploring the alternative source of energies, being more specific green energies. In modern days, when growing energy scarcity is a hot topic and considered as a global threat, in that context a green technology capable of sustainably addressing...

This study was conducted to investigate the effect of different types of organic wastes (grass and newspaper wastes, cow dung and their combination) on physicochemical properties during vermicomposting using Eisenia fetida. Three set-ups were conducted in which three experiments were for composting...

Municipal solid waste (MSW) landfills are one of the major and most preferred waste management options in the United States and many other countries across the globe. The waste in conventional MSW landfills undergoes very slow decomposition due to limited amount of moisture. In this regard, the...

This paper presents the results of an experimental study carried out in field-scale test cells in order to determine the effect of aeration and leachate recirculation on waste decomposition rate, solid waste characteristics, landfill gas composition and settlement in the landfill body. Four landfill...

In recent years, n-hexadecane, a component of diesel petroleum hydrocarbons, is frequently detected as the contaminant in many soils and water resources. The main aims of this study were focused on the feasibility of using the biodegradation for the removal of n-hexadecane from the soil-slurry...

The objective of this study is to examine the ability of a compost material for removing {Cu}^{2+} from aqueous solutions with different parameters using continuous fixed-bed column. Compost was characterized by using Fourier transform infrared spectroscopy which revealed that the metal binding is...

Uncontrolled landfill leachate generation portends danger to the environment and aquatic ecosystem, especially without prior treatment before discharge. The application of Al-based coagulants, such as polyaluminum chloride (PACl), has the potential of introducing Al residuals into water bodies...

Municipal solid waste generation in Malaysia has increase significantly. Organic materials continue to be the major portion of solid waste generated in Kampar, Malaysia. As a result of increasing rate of waste generation and population growth, land area will become more demanding causing the...
