How to Start a Local Service for Collecting and Processing Used Cooking Oil into Biodiesel?

This is an eco-friendly startup idea. Here’s the roadmap:1. Legal – Get a Pollution Control Board clearance and state biofuel permits. 2. Collection Network – Partner with hotels, restaurants, and housing societies. 3. Processing Unit – Invest in a small biodiesel reactor (transesterification process). 4. End Market – Sell biodiesel to local transporters, industries, or state agencies. 5. Promotion – Highlight sustainability. Many hotels will pay you to collect their waste oil. Investment starts from ₹10–15 lakhs for a small-scale unit.
