The slag generated in the rotary furnaces is classified hazardous waste. In this regard, landfill disposal of lead smelting slag is not feasible since a few hundred tons are produced per year; leaching of heavy metals into ground water is of concern. The release of heavy metals into the environment...

The present study systematically and comprehensively reviewed different aspects of treating Acid Mine Drainage (AMD) with active treatment and waste materials. The work also critically reviews the status and the factors associated with the treatment process. Although, conventional active methods are...

Technological development combined with a rapid and global market penetration has led to high volumes of Waste Electrical and Electronic Equipment (WEEE). Simultaneously, the use-phase has become shorter resulting in an annual growth rate of WEEE between 3-5%, which makes WEEE one of the fastest...

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...

Agriculture is a major driver of sustainable development in developing countries. However, with the increase in the global population, the amount of waste generated by agriculture has also increased, leading to environmental pollution. The increase in agricultural activity is proportional to the...

Green Chemistry is a philosophy of chemical research and application that encourages the design of appropriate products/ processes in order to minimize the use and production of hazardous chemicals. Green Chemistry involves the application of new, milder synthetic pathways, the avoidance of toxic...

The use of Prosopis Juliflora (PJ) ash as a supplementary replacement for cement in paver block production presents a promising sustainable solution for the construction industry. PJ is an invasive plant species that poses significant environmental and socio-economic challenges in many regions. This...

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...

In recent days, massive quantity of waste materials gets considerable increased with increasing population. Proper management of waste materials becomes essential to reduce environmental degradation and improve quality of life in smart cities. Waste management helps to collect and treat waste...

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...

Industrial wastes represent a huge issue for the environment and precious materials for microbial growth. Utilizing these wastes in different fermentation process decrease the costs of production, materials, energy, and represent an eco-friendly way of waste recycling. Aspergillus niger (ASU49) is...

The primary aim of this research is to identify the best anaerobic digestion process yield for generating biogas from mixed food waste in the combination of cow manure. For the biogas generation experiment, certain biodegradable domestic organic wastes gathered from restaurants, waste storage...

The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes a crisis in the waste disposal and thereby contributes to environmental issues. Recycling concrete manufacturing waste materials not only offers...

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...

Decision support systems (DSS) are used to aid at solid waste management, a tedious problem with many technical, economic and social constraints. The main DSS available are briefly presented and the development of a novel system, ReFlows, is described. The novelty of the developed DSS consists of...

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...

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...

Jarosite waste released from the zinc production process during the hydrometallurgical leaching of concentrates in Trepça lead-zinc smelter, Kosovo has serious environmental problems due to the presence of toxic metals such as Pb, Cd, Zn, As etc. Its disposal in open tailing damps has become a major...
