The aims of this work were to develop a mathematical model for composting municipal solid waste (MSW), to verify the proposed model with independent experimental data and to determine the optimum values for the initial moisture content and airflow. Separated MSW (with the addition of poultry manure, mature compost and sawdust) was used as materials for laboratory simulation. The experiment was ...

in order to investigate the response of coneflower to applying chemical fertilizer and incorporation with municipal solid waste compost (mswc), a pot experiment was conducted as completely randomized design with six treatments included: control (without applying chemical fertilizer and compost), chemical fertilizer (150 kg n, 120 kg p2o5 and 250 kg k2o per hectare from urea, triple super phosph...

This research aimed is to get one kind of best organic material on onion bulb production (Allium ascalonium L.). experiments using Randomized Block Design factor combinations species and dosage matter. Organic materials used are compost chicken coop, cow shed, goat cage, solidand municipal waste with dose 10 ton ha-1 15 tons ha-1. Parameters observed were plant height, number leaf, tillers, fre...

The application of Municipal solid waste as compost (MSWC) in agricultural fields has become one the most common practices. Besides its benefits, it poses some harmful effects on soil, increases heavy metal content MSWC soil. It is necessary to find a way reduce bioavailability metals before into This study aimed at exploring efficiency zeolite an immobilizer dwindle bioavailability. An incubat...

The Summitville Mine was a high-elevation (3500 m) gold mine in southwestern Colorado. The mine was abandoned in 1992, leaving approximately 200 ha of disturbance comprised partially of an open pit, a cyanide heap leach pad, and two large waste rock piles. Reclamation of these mine facilities is challenging due to extreme climatic conditions in conjunction with high acid-production potential an...

To observe the comparative effects of poultry manure, household waste compost and fertilizers and their combinations on growth and yield of maize (Zea mays L.), this experiment was conducted in the crop field of the Department of Soil Science, University of Chittagong, Bangladesh during Rabi season in 2010-2011. There were ten treatments, one control and nine fertilizer combinations. In three s...

Municipal solid waste and sewage sludge are produced in large quantities that often managed through industrial composting treatment. Because of their origin, composition, complexity, ensuring adequate stabilization the organic matter, sanitation fecal contaminants during is utmost significance, difficult to achieve on an scale. In this study, operations six facilities process municipal were eva...

Conversion of productive agricultural land towards growth of energy crops has become increasingly controversial. Closed landfill sites represent significant areas of brownfield land, which have potential for the establishment of energy crops. Increasingly composts are now being produced from the degradable fraction of mixed municipal solid waste (MSW) and are commonly referred to as Compost-Lik...

Background and purpose: The most important parameter is heavy metal contents in compost production technology. These heavy metals residue from substances like soap, detergents, cosmetics, packaging, leather and butteries are existed in municipal solid waste. The heavy metals can produce toxin for animal, human and plant. The aim of this research was study of produced compost quality based on he...
