objective: dental solid wastes often contain hazardous substances. the first step of management of dental solid wastes includes detection and classification of these substances. 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 ci...

conclusions considering the weight percentage of food wastes (70%), solid wastes of babolsar city could be used for composting. also as large quantities of infectious wastes were produced by hospitals of babolsar, it is recommended that sterilization systems (hydroclave) be used for decontamination of these hazardous wastes. materials and methods this study was a descriptive and cross-sectional...

The European Union Landfill Directive (1999/31 EC) promotes more environmental friendly waste management options, by reducing the amount of wastes and more specific of biodegradable wastes, disposed of in landfills. The EU member states are adopting the mechanical-biological treatment process for municipal solid waste and non-hazardous industrial wastes to comply with the abovementioned Directi...

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...

The remarkable benefits associated with bringing to bear, the application of renewable energy carriers including fermentative hydrogen and methane, cannot be understated. Meanwhile, considering the tremendous benefits associated with the conversion of wastes to the two energy carriers (fermentative hydrogen and methane); people might be curious to know why the commercial application of the gree...

Many conventional practices in the production and use of water, energy, and food are unsustainable. Existing technologies and concepts can be improved with the integration of forward osmosis, a membrane-based technology that uses osmosis as its driving force. This Feature highlights five emerging applications of forward osmosis that elegantly bypass the difficult step of draw solution regenerat...

Recent years have seen significant increases in the average heating values of wastes in Central Europe. Essentially, this can be attributed to recycling measures, separate recovery of waste streams, and treatment and processing procedures in modified waste management concepts. As a result of the above and due to the increasingly frequent application of energy recovery procedures for commercial ...

municipal solid wastes (msws) vary in terms of quality and quantity, especially their toxic content. the efficient and sound disposal of msws not only needs implementing an integrated management procedure, but also performing a conservative way to reduce the impacts on resources. in the present research, after characterization of msw streams and consideration of disposal methods practiced in si...

The massive production of urban and agricultural wastes has promoted a clear need for alternative processes of disposal and waste management. The potential use of municipal solid wastes (MSW) as feedstock for the production of polyhydroxyalkanoates (PHA) by a process known as syngas fermentation is considered herein as an attractive bio-economic strategy to reduce these wastes. In this work, we...
