Why your oil is different from a restaurant's
Continuous fryers, known oil type, high weekly kilolitres. Buyers will ask FFA and whether you filter. You can command a better rate than mixed hotel drums if you document that.
Plant SOP
Dedicated UCO tank, water drain, no floor-wash into the tank, COA on request. Treat it as a by-product SKU, not garbage.
RUCO paperwork
NFP-authorised offtake, invoices, and FSSAI records. Marketplace trades keep the commercial file aligned with the food-safety file.
Sell plant UCO
Raise or answer RFQs on BioTradX for used cooking oil from manufacturing, not from HORECA, so buyers size tankers correctly.
