This study examined toxics use reduction measurement among metal intensive manufacturers (SIC 34-39) located in Massachusetts. Of the 110 study fms chosen from a stratified random sample, less than half said they documented and measured their toxics use reduction progress. During on-site visits with twenty-eight of these fms, roughly half measured their progress accurately. Toxics use reduction...

The classical electrostatic image principle for a perfectly conducting object consisting of two orthogonally intersecting spheres is revisited through vector analysis. A method for finding the image of a given charge distribution by splitting it in three virtual singlesphere problems is described. Also, a simple relation between the image charges of a given point charge is found. The method is ...

Effective legislation is the main driving force in controlling pollution and, indirectly in economizing in the use of water in industry. The control is exercised by municipal authorities over the discharge of waste water to public sewers or of river agencies that determine the quality of discharges to rivers. Important factors in the reduction of pollution in the metal finishing industries are ...

Objective(s): A remarkable growing effort has been conducted by several researchers to fabricate food packaging materials which are able to protect foodstuffs and enhance their shelf-life from food-borne pathogens and fungal attack which causes great damage to the food industries. Recent studies has focused on the potential applications of nano-metal oxides in food packaging area. Method...

Sultan I. Amer, Ph.D. AQUACHEM INC. Environmental Technology • March/April 1998 Wastewater from metal finishing industries contains high concentrations of contaminants which are hazardous to the environment and pose potential health risks to the public. With increasingly stringent regulations governing wastewater discharge and greater quantities of wastewater being produced, there is a growin...

The success of printing technology in the electronics industry primarily depends on the availability of metal printing ink. Various types of commercially available metal ink are widely used in different industries such as the solar cell, radio frequency identification (RFID) and light emitting diode (LED) industries, with limited usage in semiconductor packaging. The use of printed ink in semic...
