The content, behaviour and significance of heavy metals in composted waste materials is important from two potentially conflicting aspects of environmental legislation in terms of: (a) defining end-of-waste criteria and increasing recycling of composted residuals on land and (b) protecting soil quality by preventing contamination. This review examines the effects of heavy metals in compost and ...

OBJECTIVE Along with increasing livestock products via intensive rearing, the accumulation of livestock manure has become a serious issue due to the fact that there is finite land for livestock manure recycling via composting. The nutrients from livestock manure accumulate on agricultural land and the excess disembogues into streams causing eutrophication. In order to systematically manage nutr...

in this study fertilizing potential of municipal solid waste (msw) compost was investigated by the distribution behavior of heavy metals, nutrient elements and salinity content among the different size fractions. therefore, 3 compost samples (each composed of 6 subsamples) were collected from sanandaj msw composting plant. then, the samples were physically divided into seven fractions of differ...

-----------------------------------------------------------ABSTRACT---------------------------------------------------------To plan effectively and successfully manage the solid wastes, proper quantification and characterization are essential. Recovery from solid waste is an important aspect where as disposal is only the final option. Recovery of methane from landfills is rarely practiced in In...

Background & Aim: Rosemary (Rosmarinus officinalis L.) is an evergreen and aromatic plant that is used in pharmaceutical and cosmetic industries-health. Little research has been reported on the greenhouse production of this plant. This paper presents the effects of municipal solid waste compost (MSWC) and cattle manure on rosemary growth in pots at greenhouse. Martial & Methods: Munic...

In this study, odorous volatile compounds (OVCs) from market−ready, commercial composts supplied by 14 different producers were compared using a recently developed method involving solid−phase microextraction (SPME) of headspace volatiles followed by GC analysis. The products analyzed were derived from a cross−section of the wide array of compost feedstock ingredients used in the U.S. (e.g., bi...

testing methods are not adequately recorded or reported, assuring the quality of the information generated—and thus, the quality of the compost produced—is impossible. Since sample collection, handling, storage, and shipping are generally conducted by facility personnel, a quality assurance program that addresses these steps must be developed by each facility. The key steps in developing such a...

in order to study the influence of municipal solid waste compost and nitrogen fertilizer on grain and forage yield of sweet corn an experiment was conducted at marvdasht during 2009. the experiment was arranged in split plots based on randomized complete block design with two factors and three replications. main plot included 5 levels of nitrogen fertilizer (100, 150, 200, 250, 300 kg n ha-1) a...

While considerable attention has been paid to the land application of sewage sludges and composted sewage sludges in the U.S. during the last twenty years, land application of municipal solid waste (MSW) composts has received comparatively little attention. However, there has been a recent resurgence of interest in this topic as other options for solid waste disposal such as landfilling and inc...

BACKGROUND In Iran, re-refinery industry has been developed many years ago based on the acid-clay treatment. Acidic sludge with high concentration of total petroleum hydrocarbon (TPH) is the final products of some facilities. In this study removal of TPH by aerated in-vessel composting was investigated. METHODS In order to microorganisms seeding and nutrient providing, urban immature compost ...
