“…Kizlary et al [8] reported that 94.7 and 3.3 % of dental waste produced by dental centers were potentially infectious and domestic type, respectively. Vieira also showed that infectious (24.3 %), non-infectious (48.1 %) and domestictype (27.6 %) wastes were the major constituents of the dental waste [21]. Therefore, the separation of potentially infectious waste and domestic-type waste is required to prevent infected waste mixed into the municipal solid waste.…”

The objective of this study was to identify the components, composition, generation rate and management of dental waste in Urmia, Iran. Fifteen dental centers including eight general dental offices, five specialist dental offices and two dental clinics were selected and two samples were taken from each office. Then, the wastes were manually separated in 31 components and weighted. The results showed that total dental waste generation in all general dental offices, specialist dental offices and dental clinics were 58.94, 17.92 and 10.22 kg/day, respectively. Domestic, potentially infectious, toxic and chemical and pharmaceutical waste also constituted 35.46, 34.24, 11.83 and 5.56 % of total waste, respectively. Only 11 components including blood-contaminated paper towel, salivacontaminated paper towel, saliva-contaminated cotton, extracted teeth, blood-contaminated gauze, inseparable components, nylon glove, tongue blade, latex glove, saliva ejector and blood-contaminated cotton constituted more than 80 % of total infectious waste generation. There was no management program (waste minimization, separation, reuse and recycling) in the dental offices. Source reduction, separation, reuse and recycling activities should be conducted to decrease the hazards of dental wastes. It is also suggested that each fraction of dental waste should be separately collected and disposed in the accordance with its related criteria.

“…Identification of the quantity and composition of dental waste is necessary to achieve suitable management options [19]. For this reason, there have been many studies on dental waste in different countries [8,[19][20][21][22][23][24][25]. Most of them have concentrated on waste composition.…”

“…The first of them is the variety of contamination sources, such as industrial waste disposal (Machemer, Hosick, & Ingamells, 2007), improper disposal of electronic waste (Ha, et al, 2009), poorly managed recycling projects (Gutberlet & Baeder, 2008), household waste processing (Bahaa-Eldin, Yusoff, Rahim, Zuhairi, & Ghani, 2008), improper incineration (Muenhor, et al, 2009) or improper disposal of medical waste or waste from analysis and research laboratories (Vieira, 2009;Huang & Lin, 2008;Blenkharn, 2006;Silva, Hoppe, Ravanello, & Mello, 2005).…”

Conception and Development of a System Used to Organize and Facilitate Access to Environmental Information and ITS Use in Areas Contaminated by Industrial Waste

In São Paulo State (Brazil) coastal area, for several years, a chemical industry discharged, without any sort of environmental control, a blend of industrial waste formed by Persistent Organic Pollutants (POPs). Judicial suits forced the company to identify and limit such deposits in order to perform environmental recovery work. Project were developed demanding preparation and handling of a large amount of documents, satellite images, aerial photographs, maps and videos with the increase of the information and knowledge management issues. This condition became even more critical as the projects started to become cross-disciplinary, involving a growing number of experts, many of them established in different cities. Those circumstances led to the generation of an Environmental Information System (BASGEO) enabling organization and facilitation of access to such documents while increasing information safety. This work shows the development of this system and the difficulties related to environmental documents management and handling.

“…Dental waste includes any type of waste materials that are generated in dental operations and stained with blood or other biological components (7). Dental clinics produce higher amounts of waste compared to other healthcare sectors; however, there has been an increase in these Copyright © 2016, Hamadan University of Medical Sciences.…”

Compared to other medical clinics, dental centers produce a relatively small amount of healthcare waste. However, they are responsible for the production of certain amounts of waste that can cause serious health and environmental hazards if not treated properly. Determining the quantity and quality of dental waste is quite necessary to plan the machinery, personnel, and transportation methods. In the current analytical cross-sectional study, 22 dental clinics were randomly selected from among 145 dental centers in Yazd. For each clinic, three samples were manually collected and distributed at the end of the work day once a week (the day was randomly chosen). The components were classified into four groups based on their characteristics and potential risk. Afterward, the collected data were analyzed using Excel. The mean per capita daily waste generation in the Yazd dental clinics was 80.179 g for each patient. In general, the Yazd dental clinics generate approximately 4 tons of waste every year. Out of this amount, infectious waste, domestic waste, chemical-pharmaceutical waste, and sharp waste account for 49.30%, 33.33%, 13.7%, and 4.2%, respectively. The results of the current study and the small amount of waste generated in Yazd suggest that a special safe site should be constructed for infectious, sharp, and keen waste; private companies should collect such waste and transfer it to this site after the waste is disinfected; and the waste should then be transferred to a municipal waste hygienic disposal site. In regard to chemical waste that may contain hazardous materials, like mercury, no suggestions other than safe burial are made.
