| dc.description.abstract | Composting of sugar cane filter cake can improve soil quality and productivity as well as sustainability of agricultural production by replenishing soil organic matter and supplying nutrients. In Metehara Sugar Factory, filter cake and vinasse generation is estimated to be 33,600 tons/year and 500 m 3 /day respectively. Thus, composting of byproducts generated in the factory is essential to reduce the environmental impact due to disposal of the waste to water bodies. In this research paper, windows composting of filter cake and vinasse has been investigated at Metehara Sugar Factory for about 8 weeks of composting period. During this process, the degradable organic substrate undergoes chemical and physical transformation to give a stable and humidified end product. The present study deals with the sources, composting and strategies for future management of filter cake. The study also, includes the quantification, characterization and economic analysis of the compost from Metehara Sugar Factory. In the experiment, the physical and chemical characteristics has been analyzed at Metehara and Wonji research center. According to the laboratory results, fresh filter cake contains 20% organic carbon and 0.8, 0.86 and 1.1 % NPK respectively. Similarly, the matured compost has 17.8% organic carbon and 1.4 %, 0.63 % and 1.27 % NPK respectively. Thus, the product is of value in agriculture both as an organic fertilizer and soil improver. The economic analysis of composting shown that recycling the nutrient yield can substitute 0.2 % of DAP consumed or saves 322,560 USD/year. | en_US |
