More Information www.agilent.com/chem/icpms Introduction Biogas is the term used to describe the mixture of methane, carbon dioxide, nitrogen and other components resulting from the anaerobic fermentation of a variety of biodegradable materials including animal waste, domestic sewage sludge and municipal landfill waste. Because of its methane content (40-75%), biogas can be used as a substitute...

Hazardous wastes include numerous kinds of discarded chemicals and other wastes generated from industrial, commercial, and institutional activities. These types of waste present immediate or long-term risks to humans, animals, plants, or the environment and therefore require special handling for safe disposal. Landfills that can accept hazardous wastes are excavated or engineered sites where th...

Landfills are a significant source of greenhouse gases, which contribute to the process of global warming. In the region covered by the Gulf Co-operation Council (GCC), changes in consumption patterns have led to an excessive dump of municipal solid waste (MSW). Thus, it is clearly an important time to re-evaluate conventional waste management protocols in order to establish methods that not on...

Recent revision of the arsenic in drinking water standard will cause many utilities to implement removal technologies. Most of the affected utilities are expected to use adsorption onto solid media for arsenic removal. The arsenic-bearing solid residuals (ABSR) from adsorption processes are to be disposed of in nonhazardous landfills. The Toxicity Characteristic Leaching Procedure (TCLP) tests ...

Delhi is the most densely populated and urbanized city of India. The annual growth rate in population during the last decade (1991-2001) was 3.85%, almost double the national average. Delhi is also a commercial hub, providing employment opportunities and accelerating the pace of urbanization, resulting in a corresponding increase in municipal solid waste (MSW) generation. Presently the inhabita...

On behalf of the International Solid Waste and Public Cleansing Association (lSWA), it is a pleasure to open this First Annual North American Waste-to-Energy Conference. Solid waste management has moved to the forefront of the environmental agenda. The level of activity and concern by citizens and governments worldwide has reached unprecedented levels. Nations are considering restrictions on pa...

How arborists view the issue of “waste wood” is changing. The number of landfills has been steadily shrinking, while tipping fees at the remaining facilities are rising continually. Disposing of waste wood was once merely a time and labor factor, but now carries with it considerably more expense. Many arborists have adjusted to the higher cost of handling waste wood by looking for value-added m...

This study reviews the problems in the use and disposal of poly (ethylene terephthalate) (PET) and includes the concise background of virgin and recycled PET as well as their possible applications. The current state of knowledge with respect to PET recycling method is presented. Recycling of PET is the most desirable method for waste management, providing an opportunity for reductions in oil us...

Alexandria Governorate contracted an international company in the field of municipal solid waste management for the collection, transport and disposal of municipal solid waste. Construction and operation of the sanitary landfill sites were also included in the contract for the safe final disposal of solid waste. To evaluate the environmental impacts associated with solid waste landfilling, leac...

Ultimately, hundreds of billions of dollars of public and private funds will be spent in the US in hazardous chemical site (Superfund and closed RCRA facilities) investigation and remediation. A critical review of the adequacy of remediation of many of these sites that are “closed” in accord with RCRA and/or CERCLA requirements as being interpreted by regulatory agency staff/boards and principl...
