Rerefine

No, sir; I am referring to the sugar which we had to rerefine after the market broke, as I explained this morning.

When working with an oil recycler, ask the person collecting the used oil how it will be recycled. If presented the choice, it is preferable to dispose of oil through companies that will rerefine the oil instead of companies that burn the oil for fuel.

He states and restates, formulates and reformulates, refines and rerefines.
