Think you don't have room for an indoor tank?  We think you do!

Let us do a free site survey and bring our 4S Indoor Solution to your store.

Our 4S Solution:

Simple. Safe. Sanitary. Secure.

Turn your oil tank into a fuel tank!

We mean it when we say our customers' greases and fats can be converted into sustainable biofuels. We can transport the Seattle area's animal fats and used cooking oils to one of our three biofuel production facilities where we process the material into clean, safe biofuel. 

  • We own and operate three biofuel facilities -
    two biodiesel and one renewable diesel
  • Our biofuels emit  up to 86% LESS carbon dioxide than petroleum diesel
  • We process 11% of the animal fats and used cooking oils generated in North America

Contact ustoday to find out how your fat can become the biofuel that powers the truck bringing your store's next delivery.
