Economics With Waste Cooking Oil
What About the Waste?• Home Brewers (like me) use the waste Glycerin

• Commercial plants sell their glycerin as an animal feed additive or distill it to 99+ purity and sell it for use in hand lotions and cosmetics.

You Can Help
• Our club is always looking for more cooking oil. If you know someone who fries a lot or owns a restaurant with
a fryer, please take a brochure and give it to them.
Thanks for your help,
