Abstract
Problem statement: Rapid urbanization and population growth are largely responsible for very high increasing rate of solid waste in the urban areas, its proper management and recycling is major problems of Municipal Corporation. The proposed study attempted to proper management, physicochemical analysis of Urban Solid Waste (USW) and its conversion to enriched compost by ecofriendly process. Approach: For this study, we used turned windrows method for composting of USW, microbial inoculums added uniformly and temperature, pH, moisture maintained throughout the composting process. The chemical composition of compost obtained at the end of the composting process compare to the United State Environmental Protection Agency (USEPA) standards. Results: A study in Jabalpur had shown the 47% of Urban Solid Waste (USW) were degradable and 53% non-degradable. The initial compositions of urban waste were indicates an organic carbon status of 38% with the C: N ratio of 950. The additives used in solid urban waste composting such as cow dung and green manure recorded organic carbon content of 25.60 and 34.60 and C:N ratio of 30.11 and 11.23. Conclusion: The results of the study clearly indicate that the recycling of solid urban waste can transform garbage or municipal solid waste to enriched composts. This is practical significance if adopted by urban farmers as a result of soil health and in turn the productivity of soil can be maintained for further agriculture.
Highlights
The need of the hour is to improve soil health by providing the much needed organic matter, least soil become impoverished
Integrated nutrient management combining both inorganic and organics resulting in wholesome improvement of the soil. Faced with such situation utilizing valuable urban resources for manure production would be viable alternative given the ever increasing urban status resulting in urban waste production. This can be done by adopting the technology of “composting”[2].The term composting refers is a biological process in which organic urban solid waste material is broken down by the action of microorganisms
Characterization of organic materials used for composting: The organic wastes collected from different sources were analyzed for pH, electrical conductivity, organic carbon, total nitrogen, total phosphorus, total potassium using standard procedures[4] and total micronutrients were analyzed by standard procedure given by[5] using inductively coupled plasma emission spectroscopy (ICAP)
Summary
The need of the hour is to improve soil health by providing the much needed organic matter, least soil become impoverished. In addition there are the benefits of a cleaner environment, a healthier habitat and an intelligent use of all available recyclable resources without condemning them as wastes Towards this end urban solid waste compost could serve as a valuable organic matter source given the shortage of organic nutrient source[1]. Integrated nutrient management combining both inorganic and organics resulting in wholesome improvement of the soil Faced with such situation utilizing valuable urban resources for manure production would be viable alternative given the ever increasing urban status resulting in urban waste production. This can be done by adopting the technology of “composting”[2].The term composting refers is a biological process in which organic urban solid waste material is broken down by the action of microorganisms. Large quantities of waste materials are they originated from forms and agro based units or from industries need to be evaluated to meet plant nutrient requirements
