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...

This study was conducted to investigate thermal aspects of municipal solid waste landfills as a function of operational conditions and climatic region. Spatial and temporal distributions of waste temperatures were determined at four landfills located in North America �Michigan, New Mexico, Alaska, and British Columbia�. Temperatures of wastes at shallow depths �extending to 6 to 8 m depth� and ...

Introduction: Countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. Therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. Materials and Methods: To conduct this review article, the scientific data related to the topic were gathered ...

Carbonization is a kind of pyrolysis process to produce char from organic materials under an inert atmosphere. In this work, chars derived from various solid wastes were characterized from the standpoint of fuel recovery and pretreatment of waste before landfilling. Sixteen kinds of municipal and industrial solid wastes such as residential combustible wastes, non-combustible wastes, bulky waste...

The treatment of liquid wastes in municipal sewage treatment plants creates significant quantities of solid residue for disposal. The potential hazard from these wastes requires that their characteristics be determined accurately to develop environmentally sound management criteria. It is readily recognized that the sludge characteristics vary with the type and degree of industrial activity wit...

In this study, the adsorptive characteristics of biochar generated from anaerobically digested garden wastes (AD-char) were investigated. Metal adsorption onto AD-chars reached equilibrium in 48 h; the adsorption capacity of Cu by AD-char was 182 μmol g, which was higher than that of Zn (35.3 μmol g) and Mn (60.7 μmol g). The metal adsorption was well described by the pseudo second-order kineti...
