Electronic waste (e-waste) is one of the fastest increasing waste streams worldwide due to unprecedented growth of the electronics industry, rapid obsolescence and subsequent disposal of electronic devices. Printed circuit boards (PCBs), the central component of electronic devices, are highly complex. PCBs are an important resource of metals, and contain substantial amounts of copper, tin, lead...

CONFLICT OF INTEREST NONE DECLARED Waste management is one of the key ecological challenges of the modern world. As dental practitioners, we must recognize that some of the materials and procedures we use to provide dental health services may present challenges to the environment. Realizing this, we can begin to take measures to minimize the production of these wastes and their potential enviro...

Few studies have investigated the occupational hazards of municipal solid waste workers, particularly in developing countries. Resultantly these workers are currently exposed to unknown and unabated occupational hazards that may endanger their health. We determined municipal solid waste workers' work related hazards and associated adverse health endpoints. A multifaceted approach was utilised c...

The waste associated with cleaning of process equipment is probably a significant contr ibutor to the total waste volume generated by industry. This paper addresses the following aspects related to equipment cleaning waste generation: o Review of reasons for cleaning process equipment o Reduction of cleaning frequency o Reduction of quantity and toxicity of cleaning waste o Costs associated wit...

Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...

Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do...

there are enormous quantities of unknown composition of hazardous wastes in tehran without any control, safe disposal and treatment. this study was done to identify hazardous wastes and to control this wastes by establishing a treatment, storage and disposal facility. according to available statistics there are 4461 different industries in tehran, out of which sample were chosen each having ove...

Safe management of electronic and electrical waste (e-waste/WEEE) is becoming a major problem for many countries around the world. In particular, developing countries face a number of issues with the generation, transboundary movement and management of e-waste. It is estimated that the world generates around 20-50 million tonnes of e-waste annually, most of it from Asian countries. Improper han...

We read with interest the article "Public Health Policies Regarding Hazardous Waste Sites and Cigarette Smoking: An Argument by Analogy" by Legator and Strawn (p. 8). The article raises a number of important points regarding the characterization of health risks presented by hazardous waste sites. In particular, the article argues that government policies and public health practice pertaining to...

Near to two decade after the Basel Convention (BC) under United Nations Environment Programme (UNEP), most of the nations are still working for Waste Electrical and JIBC December 2011, Vol. 16, No.3 2 Electronic Equipment (WEEE) or E-waste disposal programme. The Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal is the most comprehensive global environm...
