Messes and hospital kitchens fall under FSSAI RUCO when they fry at scale. How to sell used cooking oil with public-sector paperwork.
Tender vs marketplace
Some campuses tender annual waste-oil contracts. Others need a repeating vendor. A marketplace RFQ can feed either model with written specs.
What auditors ask
Who took the oil, when, how many litres, which plant. Informal mess contractors rarely survive that question.
Storage on campus
Locked, labelled drums. No student-area access. No mixing with canteen drain waste.
List the mess oil
Post institutional UCO on BioTradX with the legal name on the FSSAI licence, not the hostel nickname.
