Background and purpose: Hospital waste contains microbial agents and chemical and toxic compounds that are hazardous to the health of patients, hospital personnel, and people visiting hospitals. Considering the presence of hazardous and infectious materials in hospital waste, it is essential that it be managed suitably. This research intended to study hospital waste collection and disposal at teaching treatment centers of Sabzevar University of Medical Sciences in 2016.
Materials and methods: The present literature review on medical waste at Treatment-Teaching Centers of Sabzevar University of Medical Sciences was conducted in 2016. The initial raw quantitative data was received from the Waste Management Organization of Sabzevar Municipality. The guide issued by the World Health Organization was used to study the produced waste. Based on daily visits and completed questionnaires, the situation regarding disposed material with respect to type, collection method, storage, disposal and the degree of waste segregation at the three treatment-teaching centers were investigated. The validity of the questionnaire was confirmed by University Professors and its reliability by Cronbach’s alpha (that was 80%). Results were analyzed by using software (SPSS and Excel).
Results: The studied centers produced 869.5 kg of waste per day or 2.20 kg per occupied bed on average. Ordinary, infectious, chemical, pathological, sharp or pointed, pharmaceutical, and pressurized waste constituted 22%, 47.5%, 0.6%, 24.5%, 5%, 0.2%, and 0.2% of the total.
Conclusions: Results showed that hospital waste in Sabzevar was collected and disposed according to the circular of the Ministry of Health regarding hospital waste, waste management was supervised, and hospital waste collection and disposal was of desirable quality.

Introduction: At present time, dental solid waste management continues to be a major challenge, particularly in most healthcare facilities of the developing world such as Iran. In this country, few studies have been conducted on dental solid waste management and its composition. In this study, hazardous status of dental solid waste, which has a significant role in cross-infection chain, was studied.
Materials & methods: This work is a descriptive and cross sectional study which was performed during 2013-2014. For this research, 159 publicand private dental centers in Sistan and Baluchestan province were selected and both the composition and generation rate of dental solid waste were measured. Dental solid wastes were categorized to four main categories including domestic type, potentially infectious, chemical and pharmaceutical and toxic wastes and, finally, they were analysed.
Results: The results showed that the percent of potentially infectious, domestic type, chemical and pharmaceutical and toxic wastes were 80.3, 11.7, 6.3 and 1.7%, respectively. Also, the results indicated that the dental solid waste generation rate for total waste, potentially infectious, chemical and pharmaceutical waste, domestic type and toxic waste was 169.9, 153.3, 11.2,8.6 and 3.3 g per patient per day (g/p.d), respectively. Additionally, the generation rate of dental solid waste for total waste, domestic type, potentially infectious, chemical and pharmaceutical and toxic waste was 194.5, 22.6, 156.1, 12.3 and 3.4 kg/day, respectively.
Discussion: For the best management of dental solid waste, it is suggested that source reduction, separation, reuse and recycling programs be implemented and each section of dental waste be collected and disposed separately, in agreement with related standards.
