What a compliant used-oil handover looks like: vehicle, weighment, invoice, and why BioTradX keeps the commercial record.
Before the vehicle arrives
Dip your tank. Photograph the seal if you use one. Know your litres so you can challenge a short ticket.
At the gate
Match the recycler's name to the authorisation copy. Do not load an unknown tanker that 'came for someone else'.
After
File weighment, invoice, and marketplace ID. That is the file CPCB-era buyers and auditors understand.
Dealer-scale example
Multi-outlet dealers need the same ticket quality at every pit. That operational boringness is what circular-manufacturing coverage like The Machine Maker is actually pointing at.
