Cadmium (Cd) is a non-essential trace element that accumulates in agricultural soils through the application of Cd-rich phosphate fertiliser. Vegetables can accumulate Cd to concentrations that sometimes exceed food safety standards. We investigated the potential of low-cost soil amendments to reduce Cd uptake by spinach (Spinacia oleracea L.), lettuce (Lactuca sativa L.) and onion (Allium cepa...

background: the quality of the compost produced is one of the most important and effective parameters in its marketing and external materials presence in the compost have specific consideration. this study was conducted to investigate the quantity and quality of foreign materials in the compost produced by khomein and tehran plants. methods: this study was conducted on the compost produced by k...

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...

A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

in order to evaluate the effect of different crop management practices on corn (zea mays l.) net primary productivity (npp) and relative carbon allocation coefficients, a field experiment was conducted based on a completely randomized block design with four replications in the agricultural research station, ferdowsi university of mashhad, iran during two growing season 2008-2009 and 2009-2010. ...

Municipal compost sample was pyrolyzed to produce compost char as a sorbent for removing the herbicide atrazine from solution. The compost-based char was compared with an activated carbon derived from corn stillage. When compost was pyrolyzed, the char yield was greater than 45% when heated under air, and 52% when heated under N2. In contrast, when the corn stillage was pyrolyzed under N2, the ...

This paper provides a general overview of solid waste data and management practices employed in Turkey during the last decade. Municipal solid waste statistics and management practices including waste recovery and recycling initiatives have been evaluated. Detailed data on solid waste management practices including collection, recovery and disposal, together with the results of cost analyses, h...

Packaging waste accounted for 78.81 million tons or 31.6% of the total municipal solid waste (MSW) in 2003 in the USA, 56.3 million tons or 25% of the MSW in 2005 in Europe, and 3.3 million tons or 10% of the MSW in 2004 in Australia. Currently, in the USA the dominant method of packaging waste disposal is landfill, followed by recycling, incineration, and composting. Since landfill occupies va...

Inoculating two kinds of microbes (MS compound strains and ZHJ fermentation), study on the effect of the MSW compost on the nitrogen and maturity, the results showed, comparing with that of compost primary, the content of total nitrogen obviously declined at the end of the MSW compost. The two kinds of microbes could accelerate the transform of water-soluble NH4-N and the formation of the water...

Problem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squ...
