Ecosystem is affected by uneducated, unplanned and ineffective waste management. The cycle of garbage generation and recycling is effective to make the cities environment more pollution free, clean, green and habitable for healthy living. In an effort to understand the dynamics of waste management and scope in Delhi & NCR the paper looked at the systems in place for collection and recycling of ...

The European perspective on waste management and recycling as described in the European Union’s Waste of Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (ROS) strongly suggests that lead-free electronic assemblies will be mandatory in Europe by 2008. Japan is moving toward voluntary compliance by 2003 with a lead-free initiative that focuses on environmental m...

During incineration of wastes in waste incineration plants, polluted flue gases are generated which have to be subjected to flue gas purification. Although the legal requirements are nearly unambiguous, the question of whether wet flue gas purification is to be performed in a sewage-free or sewage-generating manner is discussed controversially by experts in the Federal Republic of Germany. As a...

in the present investigation, for the first time in iran, dewatered sludge waste from air heater washing wastewater treatment of a thermal power plant was subjected to investigation of the cement base stabilization and solidification experiments in order to reduce the mobility of heavy and other hazardous metals as well as increasing the compressive strength of the solidified product for possib...

Several studies have shown that the waste heat from forced-air warming (FAW) escapes near the floor and warms the contaminated air resident near the floor. The waste heat then forms into convection currents that rise up and contaminate the sterile field above the surgical table. It has been shown that a single airborne bacterium can cause a periprosthetic joint infection (PJI) following joint r...

At the present day in Russia the change of ferrous metals production technology results in the change of the chemical composition of solid waste from iron and steel works. Traditional approaches to waste recycling methods stop meeting the requirements of geoecological safety. The paper offers a methodology of usage of the ferrous industry waste taking into consideration a life cycle of the mate...
