Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 25...

Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Therefore, it is necessary to ensure a timely warning for possible accumulation of polluting metal in natural waters in order to protect public health. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. The purpose of this study ...

Municipal solid waste management system (MSWMS) includes MSW generation, storage, collection, transfer and transport, processing and disposal. The planning of an optimal MSWM strategy requires a reliable tool for predicting the amount of municipal solid waste (MSW) that is likely to be produced. The MSWMS is a complex, dynamic and multi-faceted system depending not only on available technology ...

introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...

Three different types of compost, PM-5 (poultry manure compost), 338 (dairy cattle manure compost), and NVIRO-4 (alkaline-pH-stabilized dairy cattle manure compost), and irrigation water were inoculated with an avirulent strain of Salmonella enterica serovar Typhimurium at 10(7) CFU g(-1) and 10(5) CFU ml(-1), respectively, to determine the persistence of salmonellae in soils containing these c...

Title of Dissertation: ASSESSMENT OF FOODBORNE PATHOGEN SURVIVAL DURING PRODUCTION AND PRE-HARVEST APPLICATION OF COMPOST AND COMPOST TEA David T. Ingram, Ph.D. 2009 Directed By: Sam W. Joseph, Professor (Emeritus), CBMG and Director, Maryland Institute for Applied Environmental Health Jianghong Meng, Professor, NFSC, and Interim Director of the Joint Institute for Food Safety and Nutrition The...

Effective management of windrow-based composting technology in developing cities is a major challenge, especially for municipal authorities mandated to offer these services. Poorly managed waste systems could affect the quality compost and cause complex environmental impacts. The aim this study was assess facility Mukono municipality, central Uganda. Mature samples were collected from windrows ...

Potato productivity in the northeastern US has been relatively constant for over 50 years, raising questions about what factors are limiting productivity. Research was initiated in 2004 to identify key constraints to potato productivity by evaluating Status Quo (SQ), Soil Conserving (SC), and Soil Improving (SI) cropping systems under both rainfed and irrigated management, and it was found that...

This study aimed to evaluate the effect of initial moisture content on the in-vessel composting under air pressure of organic fraction of municipal solid waste in Morocco in terms of internal temperature, produced gases quantity, organic matter conversion rate, and the quality of the final composts.For this purpose, in-vessel bioreactor was designed and used to evaluate both appropriate initial...

Waste accumulation is reported to be one of the serious environmental problems. Organic wastes such as organic fraction of municipal solid waste (OFMSW) or sewage sludge (SS) can be treated using aerobic microbial decomposition called composting. It is important to know when composts obtained in co-treatment processes turns to be safe but not toxic for the environment. In this study, we estimat...
