Extended abstract1- IntroductionMankind has always paid attention to the management of waste for millennia. In early times, waste wouldn’t cause a problem entering environment because humans’ population was low and lands were abundantly accessible. But cities emerged and population density increased which caused waste to increase per unit area. Consumables increased in number which caused waste to increase and enter environment. Humans must take into consideration the accurate methods of management as well as the engineering and economic principles in order to fight such infections. Although there’re various methods for dumping waste, the recovering of waste is of the utmost importance nowadays because this method not only decreases the amount of waste and prevents further environmental pollution but also saves money, energy and natural resources. The average daily amount of waste made in the city of Boukan is 150 tons. The amount of waste is never separated and is dumped in a hazardous manner. 2- MethodologyThe method for this applied study is descriptive, analytical and evaluative; and the data is collected from libraries, field studies, and 330 questionnaires conducted utilizing a random sampling method in 3 areas of the city. The city was divided into three parts for data to be analyzed. Then 30 samples of garbage were gathered from homes in each area and were analyzed physically, also hypothesis including two independent variables (the condition and improvement of management), and one dependent variable (the amount of waste decreased) were analyzed using SPSS and inferential statistics (simple linear regression, Pearson's correlation). 3- DiscussionThe total amount of waste made in the city is 150 tons per day. The waste is mostly consisted of decaying materials which comprises 77.9 per cent of the total waste on the average, and metals comprise a total percentage of 3.1.The amount of waste expected to be made in the city in the next 20 years i.e. 2009 to 2028 was analyzed and estimated an amount of 1296856050 kg taking into consideration the rate of population growth of 1.18.In the city, home waste comprises the most amount of the total waste which consists of food waste and decaying materials (77.9 per cent), and can be used as compost or organic material.
