  7. Abstract:
  8. With the increasing population and expanding urbanization and changing consumption patterns and relative prosperity increases, the amount of waste generated has increased significantly. So the municipal waste management as one of the challenges that lie ahead for municipal and state has become. Therefore, different approaches have been proposed to solve this problem. In the past government used landfill or incineration program for waste management. Given the risks to the environment and human health are two ways to create and large amount of biodegradable solid waste, composting seems to be good approach for waste management. With using the process on an industrial scale by municipalities, in one place, this requires the collection of debris around the city and is transported to the waste processing site. Such transformation requires a considerable manpower combined with fuel consumption. For this goal decentralized municipal solid waste can be used.it means that the composting can be carried out in the houses or in communities instead of gathering and processing all the waste that a city makes in a processing cite outside the city. This study was performed in two separate methods. In the first method, house-hold scale composter was used and composting at different percent of incubation with cow manure was investigated in the fed- batch operation. And result show that 30 percent has the best choice for incubation. In this scale effect of ammonium phosphate addition also has studied at batch operation
