Background : Waste materials are a matter of concern in most societies. In our country there is no documented analysis of these waste materials, thus, the resent study was designed to analyze the hospital wastes physically.

Materials and methods : It was a descriptive study. Samples were gathered from hospital wastes of Shahid Beheshti, Shabih Khani, Matini, Naqavi, and Akhavan. Totally, 60 samples were gathered during the study. Then, a 50-kg sample was prepared, for which, waste analysis was performed according to different particles.

Results : Totally, 15012 kg wastes were gathered. Shahid Beheshti had the highest and Matini the lowest wastes. Different particles were as follow: decayed materials 15.7%, plastic 13%, papers 5%, cloth 4.5%, glass 3.7%, metals 2.1%, and nylon 1.9%. Average monthly amount of waste for each Shahid Beheshti hospital bed was 2.9kg, for Naqavi, Shabih Khani, Matini and Akhavan hospitals were 3.6, 5.9, 4.5, and 3.7 kg, respectively.

Conclusion : The monthly average amount of wastes is high in Kashan hospitals. It is worth surveying.
