This study investigated effects of mature compost on gaseous emissions during composting using pig manure amended with corn stalks. Apart from a control treatment, three treatments were conducted with the addition of 5% (wet weight of raw materials) of mature compost: (a) mixing raw materials with mature compost at the beginning of composting; (b) covering raw materials with mature compost thro...

We examined physicochemical and biological parameters in order to assess their effectiveness as stability and maturity indicators during the forced-aeration composting process of chicken manure mixed with different amounts of sawdust, yielding initial C/N ratios of 12, 18 and 28. The composting mixture with initial C/N ratio of 28 maintained the temperature exceeding 55 degrees C for more than ...

Submission : January 20, 2013 Accepted : February 20, 2013 Abstract — Inhibitory effect of ammonia on the organic matter degradation at the outer region was simulated using a composting system consisted of two miniature-scale reactors with different constant temperature connected in series. The lower and upper reactors were incubated at 70 and 40 oC, respectively. Composting runs were conducted...

leiomyomas are benign tumors of the soft tissue and may develop in any location where smooth muscle is present. leiomyoma in the inferior vena cava is a rarely seen pathology, and symplastic leiomyoma is also a rare histological variant of leiomyoma. in this case, we present a rare histological variant of symplastic leiomyoma in the inferior vena cava (ivc). this is the first radiologically rep...

Composting is a widely-used method to recycle the nutrients in livestock manure for agriculture. The spatial stratifications of microbial processes inside the manure particle that determine organic and nitrogen transformation are virtually unclear. Here, we show the evolution of the interior microenvironment of swine, cow and chicken manure by using microelectrodes during forced-aeration compos...

Background and purpose: Direct application of sewage sludge in agriculture is limited due to the presence of pathogens, improper fermentation of organic waste and heavy metals in the sludge. Co-composting of sewage sludge and other waste is a method for safe and healthy disposal to reuse sewage sludge. This study investigated the possibility of producing compost from sewage sludge and pistachio...

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)...

The management of Municipal Solid Waste (MSW) in Nigeria and most developing countries has remained a major public health challenge, thus creating the need for reliable and environmentally-acceptable alternatives. This study focuses on composting assessment as a viable recovery alternative for MSW in six States of Southwest Nigeria, namely: Ekiti, Osun, Ondo, Ogun, Oyo, and Lagos. Extensive lit...
