In my opinion, we ought to stop making our own drums and accept that outside suppliers offer, said Wim Niewindt, managing director of Antilles Refining, N.V., of Aruba.

Since we use 80,000 drums a year, that would be an annual cost savings of $436,000. Antilles Refinings current cost to manufacture one drum is given below
