What re-refiners cannot fix cheaply
Emulsified water, chlorine, and heavy solvent cuts. Those lots go to lower-value recovery or rejection. Segregation at the pit is cheaper than plant chemistry.
EPR demand
As producer recycling targets rise toward 2030-31, legitimate re-refining capacity needs feedstock. That is a seller's market for clean lots.
How to sell a clean lot
Engine oil only, closed tank, COA if you are a large fleet, authorised recycler. BioTradX RFQs should state 'engine oil segregated'.
Dealership example
Branded workshops can hit this spec if they follow a SOP. That is the operational core behind coverage such as OEM Update and Industry Samachar, not only a CSR headline.
