Waste metals in the form of metal oxide (hydroxide) sludges are generated in significant amounts by the metal finishing industries, and their accumulations pose problems for disposal and challenges for recycle. The availability of technically feasible efficient separations of metals such as nickel, cobalt, chromium, cadmium, copper, tin, zinc, lead, manganese, molybdenum, and titanium from plat...

Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, aware‐ ness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including pr...

Plastics are low molecular weight organic materials, that are non degradable in the natural environment. Generation of plastic waste constitutes a major part of Municipal Solid Waste. This creates a lot of environment pollution, which in turn affects ecosystem and human health. The solution to tackle this dreadful situation lies in following 3R namely Reduce, Reuse and Recycle. Waste plastics c...

Department of Environmental Engineering, Faculty of Civil Engineering, Universiti Teknologi Malaysia, 81310 UTM Skudai, Malaysia Corresponding Author: Johan Sohaili ___________________________________________________________________________ Abstract From the use of renewable resources and environmental protection viewpoints, recycling of waste printed circuit boards (PCBs) receives wide concern...

In recent years, the disposal of organic wastes from domestic, agricultural and industrial sources has caused increasing environmental concerns. In this regard, the recycling of utilizable waste is feasible. This can be solved by combination of effective technologies like Biodung composting and Vermitech (incorporating earthworms for the production of vermicompost). The present work was carried...

This paper examines the technical, economic and environmental justification for the solid waste management hierarchy. The hierarchy ranks waste management methods, prescribing that it is best to reduce the generation of waste at the source, then to recycle and compost what cannot be reduced, and finally to incinerate or landfill the remainder. While the hierarchy has received widespread support...

Industrial pollution prevention has been incorporated into several aspects of the chemical engineering curriculum at The University of Tennessee. One is an industrial internship program. This technology selection example focuses on a case from a pilot internship project sponsored by a pesticide manufacturer. This project involved synthesis and evaluation of waste management strategies for reduc...

background : due to the crucial role of dental solid waste in the spreading of pathogens and threats to human health and the environment, its optimal management is very important. methods: this was a descriptive cross-sectional study. the study population consisted of 40 dental centers, from among which 11 dental centers were selected through random sampling. from each center, 3 samples were co...
