Research was conducted to evaluate the feasibility of producing methane gas from combined segregated municipal and agricultural waste. The combination of the two wastes resulted in sufficient nutrient value and bacterial diversity to improve the biodegradability of cellulose and increase the efficiency of gas production from the combined wastes. The feedstock included municipal solid waste with...

in order toa desirable growth, plants need fertile soil which has the availability of nutrient elements in it. sometimes, in spite of having access to the nutrient elements, decrease yield, due to undesirable physical situation. stock (matthiolaincana cv. column crimson) is one of the potting flower that its growth medium traditionally including hawar soil, basin sediment and untreated waste mu...

In order to examine the optimal design and operating parameters, kinetics for microbiological reaction and oxygen consumption in composting of waste activated sludge were quantitatively examined. A series of experiments was conducted to discuss the optimal operating parameters for aerobic composting of waste activated sludge obtained from Kawagoe City Wastewater Treatment Plant (Saitama, Japan)...

This paper examines the potential of improving the stability of thermophilic anaerobic digestion of source-sorted organic fraction of municipal solid waste (SS-OFMSW) by adding leachate and compost during inoculation. For this purpose, two stable thermophilic digesters, A (control) and B (with added leachate and compost), were subjected to a sustained substrate shock by doubling the organic loa...

Long-term application of fertilizers containing P, especially organic fertilizers, usually increases the water soluble and available P of soil and at the same time may result in P accumulation in soil. Organic fertilizers may also increase movement of P in the soil profile that could result in surface and ground water pollution. An experiment was conducted on field plots that received three app...

determination of physical properties of municipal waste compost is necessary to obtain the parameters related to designing and constructing a suitable pelleting machine for producing compost pellets. the purpose of this study is determining some physical properties such as; bulk density, coefficient of friction, porosity, angle of repose for compost and density and expansion for compost pellets...

This study aimed to monitor the process parameters and to determine kinetics in composting of organic fraction of municipal solid waste (OFMSW) and poultry manure. The experiments were carried out with three different mixtures. The results showed that the mixture 60% OFMSW, 20% poultry manure, 10% mature compost and 10% sawdust provided the most appropriate conditions for composting process. Us...

This study was undertaken in the context of a project of reclamation of a burned forest area applying municipal waste compost (MWC) and it consisted of an incubation experience carried out under laboratory conditions. The objectives of this research were to asses the effect of three doses of MWC added to burned and unburned calcareous soils on a) SOM mineralization and b) soil microbiological p...

a field study was conducted in qaen region using complete randomized blocks with three replications to study the effect of organic manure, zinc and boron on yield and yield components of millet and grain chemical composition. the treatments included factorial arrangement of municipal solid waste compost and cow manure (each at 25 ton ha-1), zn (0, 50 kg ha-1) and b (0, 10 kg ha-1) by using thei...
