Abstract :

Target field: With the increasing urban population, increasing prosperity, extreme consumerism and changing patterns of people's lives, has increased the amount of waste. In the absence of waste management, will be many environmental problems. The purpose of the research is to evaluate and understand the current state of waste in Yazd city, to explain and analyze the strengths and weaknesses of the waste system, and to formulate waste management strategies for this city.Analysis method: The nature and method of research is descriptive - analytical. Information is collected by field and library studies. This study was conducted in Yazd city. The waste situation in Yazd city is studied by D.P.S.R model. Driving forces include population, household welfare and consumption pattern. Pressure factors are commercial, office, educational, cultural, industrial workshops, health centers. After examining the Driving forces and pressure factors, the present situation is described. The swot model has been used to provide responses.Findings: Region 2 with the highest density of the population has the highest amount of waste in the Yazd city. Per capita waste in1 Region, is lower than other areas of Yazd city. Per capita waste in 3 Region is higher than other parts of the city. The implementation of source separation program is the most important strength and lack of citizen participation is the most important weakness. Low waste per capita and sustainable employment through the recycling industry is the most important opportunities. The negative attitudes to waste-related occupations and the inadequate cooperation of other organs are the most important threats.Results: Population density leads to more waste production, but the composition of waste depends on the welfare status of citizens. Comparison of wet and dry waste in Yazd city in 1385 and 1394 shows that the amount of dry waste has increased compared to wet waste, which is an indication of the change in the consumption pattern in Yazd city.
