Treatment Through Vermicomposting

Eisenia fetida (Red Wiggler) Vermicomposting System

A cornerstone of AASTMT's organic waste treatment strategy is the vermicomposting system utilizing the earthworm Eisenia fetida (commonly known as the red wiggler). This biological treatment method processes organic waste through natural digestion by earthworms, producing nutrientrich castings called vermicompost.

Process and Benefits:

• Biological Treatment: Earthworms feed on organic waste materials, digesting them and converting them into vermicompost—a dark, crumbly substance exceptionally rich in organic nutrients and plant growth hormones.
• Food Waste Processing: The vermicomposting system treats a significant portion of the 15 tons of food waste generated this year.
• Environmental Impact: Vermicomposting significantly reduces greenhouse gas emissions compared to landfill disposal, as the aerobic decomposition process produces minimal methane.
• ValueAdded Products: Beyond vermicompost, the earthworms themselves have high protein content (up to 70%), and dried worm meal can be used as supplementary feed for fish and poultry, creating additional economic value.
• Circular Economy: This closedloop system transforms waste into valuable agricultural inputs while reducing reliance on chemical fertilizers.
