Field experiment was conducted in 2008 at the Research Field of Agricultural College of Shiraz University, Shiraz, Iran to investigate the effects of urban waste compost (UWC), manure and chemical fertilizer on the initial growth of corn (Zea mays). Experimental design was split plot factorial with three replications. Main plots were assigned to nitrogen (N) fertilizer (0 and 200 kg N ha-1), an...
Introduction: In Tehran with a population of 9 million currently, about 2.5 million tons municipal solid waste have been producing annually. Materials and Models: In this study by using Life Cycle Assessment (LCA) model an optimal system of waste management of Tehran was recommended. Based on the quantity and quality of waste in Tehran in 2013 and facilities, three scenarios were selected. Fir...
to evaluate the effect of application of municipal solid waste compost (mswc) on the accumulation of heavy metals of lead, nickel and cadmium in the soil under maize cultivation, a factorial experiment in base randomized complete block design (rcbd) with four different amounts of municipal solid waste compost (zero, 15, 30 and 60 tons ha-1) and time (compost applied once or twice) was performed...
separation approaches affect organic contaminant levels. Thus, this fact sheet will focus primarily on heavy metal contaminants. Those metals of greatest concern in compost—cadmium, mercury, and lead—can be harmful to animals and humans at relatively low concentrations and tend to accumulate in soil, plants, and animals. For most of these potentially harmful metals, the levels in MSW composts a...
Background & objectives: Increasing solid waste has made waste management an important challenge in developing countries. The purpose of this study is to comparative evaluation of the application of incineration technologies and other waste disposal methods in Iran using the Analytical Hierarchy Process (AHP) in 2019. Methods: In this descriptive-applied research, after making a hierarchy, the...
field experiment was conducted in 2008 at the research field of agricultural college of shiraz university, shiraz, iran to investigate the effects of urban waste compost (uwc), manure and chemical fertilizer on the initial growth of corn (zea mays). experimental design was split plot factorial with three replications. main plots were assigned to nitrogen (n) fertilizer (0 and 200 kg n ha-1), an...
In-vessel composting, a contribution to sustainable solid waste management, was conducted on source-separated waste materials generated in Abeokuta city, south-west Nigeria. Feedstock (household, agricultural and municipal waste) and the resultant composts were chemically characterized using standard procedures. Identification and changes in the microbial population during composting, the effec...
to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with th...
