in order to investigate the effect of municipal solid waste (msw) compost and sewage sludge (ss) on yield and concentration of heavy metals in soil and black cumin (nigella sativa l.) an experiment with msw compost at 0, 15, 30 t.ha-1 (c0, c15 and c30) and sewage sludge at 0, 15, 30 t.ha-1 (s0, s15 and s30) in a factorial experiment based on completely randomized design with three replications ...
in a country like iran, where soil organic matter is less than 1% and in most cases even less than 0.5 %, municipal solid waste (msw) is a permanent and inexpensive source of organic matter. various experiments have indicated that applications of compost improve plant health, yield and nutritional quality. however, the quality of the compost determines the growth and the development of plants. ...
Organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. Composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. An integrated approach of composting methodology was tested for municipal solid waste management. Solid waste first was composted and after 22 days, was...
this paper deals with the suitability of agricultural and municipal organic wastes as growing media components for ornamental plants. nine growing media prepared by mixing the main components of peat (p), hazelnut husk (h) and maize straw (m) with the fertilizer sources of municipal solid waste compost (c), bio-solid (b) and poultry manure (pm) were compared against soil-based (c1) and peat-bas...
Municipal solid waste management is a major challenge, especially in metropolises. This research focuses on a non-technical issue in municipal solid waste management named municipal solid waste separation at the source and seeks to find the best policy in terms of model results. Source separation for recycling has been recognized as a way to achieve sustainable municipal solid waste (MSW) manag...
Medium Density Fibreboard (MDF) sawdust is an important source of carbon and is therefore in demand as an amendment in commercial municipal solid waste (MSW) composting operations. However, MDF contains formaldehyde which causes two concerns. The first one is that the bactericidal and fungicidal properties of formaldehyde may adversely affect the composting process. The second one is that forma...
Background and Objective:Application of compost containing heavy metals can increase the concentration of metals in soil and groundwater. Therefore,the aim of this study was to investigate leaching lead, chromium,and cadmium from three soils (a sandy loam, a sandy clay loam and silt clay loam) amended with compost from the municipal solid waste. Material andMethod:First, the selected soils were...
The effects of a municipal solid waste compost (MSWC) (from Villarrasa-HuelvaSpain) on growth, yield and mineral composition of tomato plants (Lycopersicon esculentum Miller, cv. Genaro) were studied. Results were compared with those observed both without the application of organic matter (Control) and with the app1ication of a commercial compost AC (made from sheep manure). Soils of the three ...
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...
