Aerobic Composting using Sewage Sludge and Vegetable Waste

Suhas Shaileshkumar Gonawala


This Paper has made an attempt to study on changeability which happens in key parameters like pH, temperature, Carbon Nitrogen ratio, Total Nitrogen, Total Phosphorous, and Total Potassium during 80 days regular testing of composting procedure. A tremendous amount of vegetable waste produced in India. The transfer of vegetable waste alongside the municipal solid waste in landfills or dumpsite is making smell irritation, leachate creation into the climate. Composting of organic waste is the easy way to produce manure which can enhance physical, chemical and biological properties of soil. The vegetable waste is easily biodegradable and loaded with nutrients and organic material. For increasing nutrients amount of the waste sewage sludge will be added in proper proportion with vegetable waste. The sewage sludge will incorporate microbes to the vegetable waste to produce high nutrients manure. For this study, aerobic composting with the help of vegetable waste blended with sewage was done. The samples were analysed after every 10 days interval period to study various characteristics like pH, Temperature, Total Nitrogen, Total Phosphorus, Total Potassium, C/N ratio and Heavy Metal. Study indicated that composting can be an alternate technology for the management of sewage sludge disposal.
