As India steps into a more eco-conscious era, one green business silently gaining traction in rural and semi-urban areas is vermicomposting – the natural process of turning organic waste into rich compost using earthworms.
It’s simple, low-cost, environment-friendly, and surprisingly profitable. With a minimal investment of ₹1–2 lakh, aspiring agropreneurs can launch a vermicompost unit that serves farmers and taps into the booming organic gardening and sustainable farming markets.
What is Vermicomposting?
Vermicomposting uses red wigglers (Eisenia fetida) or similar earthworms to decompose organic waste such as cow dung, vegetable peels, and dry leaves into vermicast — a nutrient-rich, dark compost that enhances soil fertility and crop yield.
Step-by-Step Guide to Set Up a Vermicomposting Unit
Step 1: Site Selection and Preparation
- Space Required: 500–1,000 sq. ft (open backyard or leased farmland)
- Requirement: Shade, water source, drainage
Step 2: Construction of Vermi Beds
- Beds: 4–6 rectangular brick or cement tanks (or HDPE beds for mobility)
- Size (each): 10 ft x 3 ft x 2 ft
Step 3: Sourcing Raw Material
- Base Layer: Dry straw, coconut husk
- Middle Layer: Semi-decomposed cow dung
- Top Layer: Organic waste (vegetable waste, kitchen scraps)
Step 4: Adding Earthworms
- Type: Red wigglers (Eisenia fetida)
- Quantity: ~1 kg worms per bed (₹400–₹500/kg)
Step 5: Maintenance
- Watering: Maintain 60–70% moisture (sprinkle water daily)
- Shade: Use bamboo or net shed to prevent heat
- Turn Waste: Once every 10–15 days for aeration
Step 6: Harvest and Packaging
- After 45–60 days, collect vermicast from the top layer, sieve, and pack.
