Biodegradation of Lignocelluloses in Sewage Sludge Composting and Vermicomposting
Aims of the Study: The aim of this study was to determine the amount of lignin degradation and biodegradation of organic matter and change of biomass under compost and vermicomposting of sewage sludge. Materials & Methods: Sawdust was added to sewage sludge at 1:3 weight bases to Carbon to Nitrogen ratio of 25:1 for composting or vermicomposting. Lignin and volatile solids were deter...
متن کاملStability and Kinetic Analysis during Vermicomposting of Sewage Sludge
The present study is aimed at alteration of sewage sludge into stable compost product using vermicomposting of sewage sludge mixed with cattle manure and saw dust in five different proportions based on C/N ratios (C/N 15 (R1), 20 (R2), 25 (R3) and 30 (R4); and control (R5)) by employing an epigeic earthworm Eisenia fetida. Higher reductions in C/N ratio, CO2 evolution and OUR were observed in R...
متن کاملFeasibility of nutrient recovery from industrial sludge by vermicomposting technology.
Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...
متن کاملVermicomposting of cow dung, kitchen waste and sewage sludge with bagasse using Eisenia fetida
The sugar cane industry produces significant amounts of cane trash and bagasse. Inappropriate disposal of agro-wastes can lead to environmental problems. Converting wastes such as cane trash and bagasse (Bg) to a fertilizer and conditioner is the aim of sustainable waste management in sugar cane industry. Cow dung (CD), kitchen waste (KW), and sewage sludge (SS) were mixed with bagasse as amend...
متن کاملCombined compost and vermicomposting process in the treatment and bioconversion of sludge.
Traditional thermophillic composting is commonly for treatment of sludge. A related technique as vermicomposting process, using earthworms to breakdown sludge, is also becoming popular. These two techniques have their inherent advantages and disadvantages. The combined approach suggested in this study to enhance the overall process and improve the products qualities. Two systems, vermicompostin...
