Although municipal solid waste (MSW) is generated every day , but with comparison to other municipal Environmental aspects such as Air pollution and Sewage, is not well considered. MSW management includes refuse production, storage, collection, transportation and disposal. Without adequate and reliable in formation and data about MSW generation rate and it’s physical components, optimun planning and management is not
   obtainable. In this research the physical composition of Hamadan MSW was studied .

          Samples were takan by Truck–Load sampling and portional random method from June 1999 untile May 2000 and analyzed for physical components and moisture percent age.

          The results showed that the average generation rate, density of wastes and its moisture percent were 252.33 Tons and 204.83 kg/m3 and 22.46% respectively. Average percents of physical componets were 77.72% , 5.75% , 5.42% , 3.15%, 2.11% , 1.04% and 4.92% for Biodegriable materials (garbage),
   papers, plastics, textiles, metals, glass and other materials respectively. Also maximum generation rate was 328 tons in March and minimum generation rate was 196 tons in December.

          In general, with planning of enforceable reuse and recycling
   programmes, could be avoid of 183, 14, 13 and 5 tons of biodegriable materials , paper, plastics and metals burial respectively everyday.
