In order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of Environmental impact of composting plants has been delivered. In assessment of environmental impact of Yazd composting company, Questionnaire checklist, interaction matrix and weighting checklist have been used. Our field of observation shows that the nearest residential center to the plant is Yazd city and in other directions according to our visit and land use map, any ecological and economical factor in 7 km from site plant hasn been seen and the land of project is barren and sandy. Only effective factor is prevailing wind which blows from the west/east south. So there isn any hazard for residents of this part of Yazd city. Totally, action alternative with the average of +2.17 has higher score in contrast with non action alternative with the average of -8.13; hence, project is increasingly applicable with considering mitigation measures. According to the survey the long term effects of projects is related to the operation phase in cases of leach ate and probable penetration to ground water, health risk inside plant for staff and outside environment (insects and vermin), odor and contaminated products.
