Production of carbon dioxide, methane and nitrous oxide gas emissions in biodegradation of waste oil sludge

Abstract

Biodegradation Bioremediation of waste oil sludge through biodegradation using microorganisms still has an impact on the environment, because produces of gas emissions which causes to the global warming. The purpose of this study was to determine the production of carbon dioxide, methane, and nitrous oxide gas in biodegradation of waste oil sludge by using types of bioactivator from soil as the microbe inoculums sources was compost, mangrove and forest soil with adjusting the ratio of C:N:P of 360:60:1 to optimize the biodegradation condition. The results show that the addition of bioactivator on the treatment of waste oil sludge can increase the biodegradation process. The results show that the compost bioactivator treatment is 72 percent decrease in oil sludge, the forest soil bioactivator treatment of 58 percent and then the mangrove soil bioactivator of 46 percent. The observation of gas production obtained the highest concentration of carbon dioxide was produced on compost bioactivator treatment of 0.91 ppm on the 25 day, production of methane on compost bioactivator treatment was 0.66 ppm on the 25 day and production of nitrous oxide on the mangrove soil bioactivator treatment of 0.19 ppm on the 30 day; The decrease of hydrocarbon waste oil sludge and increased gas production are also associated with an increase in the population number of hydrocarbon degrading bacteria at all bioactivator treatments.
