Abstract: The rapid generation of organic waste has led to significant environmental challenges, including improper waste disposal and greenhouse gas emissions. Composting organic waste using vermicompost provides a sustainable solution to manage biodegradable materials effectively. This study focuses on composting the organic fraction of municipal solid waste using vermicompost. The project involves the collection of organic waste such as mirchi waste(2kg), fruit waste (3kg) and vegetable waste (3 kg) from local markets. Three experiments were conducted to analyze the physical and chemical properties of the organic waste like pH, nitrogen content, phosphorus, potassium, organic carbon, and micronutrients like zinc, iron, manganese, and copper. Quantity of vermicompost applied was varied – 250 g, 500 g and 750 g and applied systematically, ensuring proper mixing to promote microbial activity. The properties were quantified both before and after composting. The lab results indicate significant increase in proportion of Nitrogen (59%), Phosphorous (43.5%) and Potassium (29%) whereas the organic carbon content and the C:N ratio exhibited a declining pattern as the quantity of vermicompost was increased. The study concludes that using vermicompost accelerates the composting process, improves the quality of compost and offers a viable method for managing organic waste sustainably. The findings suggest that compost produced through this method can be used as a high-quality.
