Alternative bio waste management by vermicomposting in cities case study: production of organic vermicompost fertilizer and study of its chemical parameters

Abstract

The aim of the project was to produce vermicomposting from organic solid wastes using the earthworm Eisenia fetida and check the nitrogen, phosphorus, and potassium level of the yielded vermicompost. This study examined the potential of the E. fetida in the vermicompost of urban organic wastes. Physical and biochemical parameters were analyzed during the period of 30 days. Pre-decomposition was 10 days and subsequent vermicomposting was 25 days. The role of these species of Verm technology was found in parameters such as total nitrogen (%), available phosphorus (%), exchangeable potassium (%) and pH.
