To analyze the impact of allocation methods of carbon allowances on the choice of recycling channels for original manufacturers under the authorized remanufacturing model. A Stackelberg game model of original manufacturer recycling and remanufacturer recycling under the grandfathering rule and...

Soil zinc (Zn) deficiency is a major constraint limiting wheat productivity and nutritional quality, particularly in degraded agricultural lands. Sustainable organic waste management through composting presents an eco-friendly approach to enhancing soil health while mitigating environmental...

Delegating public solid waste management services to private structures is increasingly favored by some countries in sub-Saharan Africa. However, waste is still landfilled without recycling and/or recovery of any fraction. This study investigated the generation, characteristics and current...

The global automotive industry is under mounting pressure to adopt highly efficient, low-emission engine technologies due to stringent regulations and increasing environmental awareness. In response, researchers are exploring alternative fuels, such as biodiesel, to enhance energy independence and...

Natural gravel used as aggregates in the construction had a severe impact on the environment leading to scarcity in recent times. Furthermore, the resistance of such natural aggregates to crack at higher temperature zones was less. This paper investigates the above concerns on scarcity and meagre...

Population growth, industrialization and technological advances have significantly increased waste production, waste collection, transportation and disposal induced significant costs. Waste could be considered a resource that allows nations to reduce the consumption of primary raw materials, protect...

Bricks have been extensively adopted for centuries and continue to play a vital role in the construction industry. Nevertheless of its dependable workability and accessibility, fired clay brick production has been recognized for its comparatively high energy and resource requirements. Traditional...

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...

Concrete is the broadly adopted composite material in the construction arena. The growing need for cost-effective housing is resulting in the depletion of environmental resources such as river sand and gravel, which are essential components in the manufacture of concrete. However, the manufacturing...

Excessive consumption of natural resources for concrete production results in the diminution of conventional resources, leading to the scarcity of construction materials. Perhaps, the dumping of construction wastes increases the municipal wastes ensuing in disposal problems. The dumped construction...

Municipal solid waste [MSW] has gained prominence in recent years as the rate of its generation has increased significantly. The serious problem of MSW management exists in almost all regions of India. This study aims to generate energy from MSW by selecting a suitable MSWM technology with the help...

The construction industry looks over the material alternatives whereby the conventionally materials can be replaced. The conventionally materials like fine aggregate, cement, as well as coarse aggregate. The replacements for the conventional materials are wider but the waste products and its by...

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...

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...

In recent years there has been a heightened concentration on the industrial subsectors that are the primary contributors to environmental pollution. Filler materials made from mineral limestone, which is composed of calcium carbonate (CaCO3), are utilized in the production of polymer composites in...

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...

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...

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...

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...

With increased contribution of household and kitchen wastes in overall MSW and its preferred conversion by biomethanation there is a need to study decomposition rates and kinetics, ‘leachate potential’ and related issues– especially to promote decentralized treatment. Anaerobic digestion...

This study was conducted to investigate the recycling of rural wastes employing vermicomposting technology by Eisenia fetida. Three medium including kitchen waste, rotting foliage and cow dung were performed in 20 treatments. Results showed that in all 20 treatments the quality of produced compost...

Emission of CH4 from landfills is a major cause of concern as CH4 is twenty four times more potent than CO2, as a greenhouse gas. However, landfills also harbor a group of bacteria called methanotrophs, which can oxidize CH4. They can be used for in situ bioremediation to reduce methane emissions...

Solid-state fermentation (SSF) process appears to be an efficient way to recover and valorise organic residues from industries and to generate other products of industrial significance, such as enzymes. As the reproducibility of SSF is one of the main drawbacks in the development of this process, a...
