Industrial feedstocks are raw materials used to make industrial products and thousands of consumer goods. Many industrial products are made from oil and natural gas feedstocks, which have a high energy content that could otherwise be used as fuel to heat homes, run vehicles, and power manufacturing processes.

Sometimes you will see a sign at a farm while driving by with that says "not for human consumption" oftentimes it's industrial feedstock
