It is easy to get the impression that there is a distinct battle' going on between those who use the terms waste minimization2 and waste red ~ c f i o n . ~ This notion, however, would preclude the concept that there may be an evolutionary transition taking place that would bring industry from one level to the next. In the related fields of environmental management4 and quality control: argumen...

Medical establishments play important roles in different activities by using of modern technology to serve the humans and the environment through different departments in the establishment and its firms. Medical wastes are considered as a hazardous waste because they contain toxic materials, infectious, or non-infectious wastes and they are considered as a hazard to millions of patients, health...

Phosphate coating hazardous wastes originated from the automotive industry were efficiently encapsulated by an acid-base reaction between phosphates present in the sludge and calcium aluminate cement, yielding very inert and stable monolithic blocks of amorphous calcium phosphate (ACP). Two different compositions of industrial sludge were characterized and loaded in ratios ranging from 10 to 50...

Mishandling of hazardous wastes, like their unauthorized disposal in abandoned dump yards or sites, in river beds, estuaries or in the sea, causes substantial damage to the environment and its resources and, given the persistence and toxicity of these pollutants, they can seriously damage human health and quality of life. The importance of controlling management, transport, and disposal of toxi...

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...

Waste minimization in the automotive repair industry is characterized by the large numbers of small quantity generators (SQG) producing solvent, alkaline and detergent hazardous wastes. On-site management of multiple processes which vary depending on the size of shop make the administration of hazardous waste policies particularly complex. This paper presents the quantities and types of hazardo...

The disposal of hazardous wastes creates major economic and environmental problems for both developed and developing nations. One productive use of hazardous wastes is to blend them into fuel, which mitigates damage to the environment by recycling waste into fuel and reducing fossil-fuel consumption. Operations personnel face a daunting task of efficiently blending hazardous waste into fuel, wh...

4. With an aim to improve the waste management, Mongolia developed the following regulations: “A rule on classification, collection, temporary storage, transportation, treatment of hazardous wastes” (2002); “Regulation and procedures on disposal and landfill of hazardous waste of business entities, and requirements on waste containers and waste disposal sites” (2006); “Methodology for calculati...

This study aimed to qualitatively and quantitatively assess the management of solid wastes by dental offices in Urmia city in 2013. Methods: This descriptive study was conducted on all private dental offices in Urmia...

conclusions based on the findings obtained, the rate of total waste generation in the amol hospital is similar in range to that of other iranian hospitals, however, the hazardous fraction of this waste was high in comparison to other previous studies, and this is probably due to improper separation and management of the waste materials. results based on this study’s findings the average rate of...
