Solid waste is the unwanted or useless solid materials generated from combined residential, industrial and commercial activities in a given area. It may be categorised according to its origin (domestic, industrial, commercial, construction or institutional); according to its contents (organic material, glass, metal, plastic paper etc); or according to hazard potential (toxic, non-toxin, flammab...

The law of toxic substances dates back to Medieval England, but the present comprehensive federal regulatory scheme was developed over the past two decades. This article presents a brief overview of the federal law of air and water pollution, solid waste control, and the regulation of chemicals.

Research posted today on ES&T’s Research ASAP website (10.1021/es0509836) describes how, in one elegant step, selected bacteria can recover precious metals from industrial waste solutions and deposit them as nanocrystal catalysts on their cell surfaces. By using the metal-covered biomass to clean up toxic chromium wastes, the researchers demonstrated the approach’s potential as a sustainable te...

Over 30 years ago, Environmental Science and Technology published a feature article, “Wildlife Toxicology”, which posed the hypothesis that “Human health is believed to be threatened by exposure to such chemical contaminants as agricultural pesticides and industrial waste. Does it not stand to reason, therefore, that the health of wildlife could be affected similarly by toxic chemical pollutant...

Are cigarette butts more than just an unsightly litter problem? Do the chemicals leached out of them just ‘go away ’dbiodegraded and diluted by our streams, rivers and oceans so that we can forget about them? This special supplement of Tobacco Control brings together the currently known science about cigarette butt waste and sets the stage for a new research agenda that can unite the tobacco co...

In this paper, we study the structure and combustion of magnegases (Patented and International Patents Pending), new clean fuels developed by one of us (R.M.S.) [1], which are produced as byproducts of recycling nonradioactive liquid feedstock such as antifreeze waste, engine oil waste, town sewage, crude oil, etc., and generally vary with the liquid used for their production. A new technology,...

Jarosite waste, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many tailing damps has become a major ecological concern. Three different methods, namely modified Synthetic Precipitation Leaching Procedure (SPLP), three-stage BCR sequential extraction procedure and Potential Ecolo...

Solid waste management has moved to the forefront of the environmental agenda. Nations are considering restrictions on packaging and controls on products in order to reduce solid waste generation rates. Local and regional governments are requiring wastes to be separated for recycling, and some have even established mandatory recycling targets. However, industrial and everyday activities continu...
