Where to dump used cooking oil ?
If you have a lot of it, as from a restaurant, there are a few of options. One is to contact a company that recycles oil. They will come and pick it up. Another is to bring it to the hazardous waste area of your local dump. In Florida there is actually a lot of thefts of cooking oil, as people are using it to make bio-diesel. Therefore, you might list your cooking oil on your local Freecycle and see if anyone is interested (Freecycles are all over, if you go to the website below, you will probably find that there is one near you…I highly recommend it, as one person’s trash is another’s treasure). If it is your household oil, a small amount, and it is completely used up (deep-fry oil can be used several times), place it into a sealed container and put it in the trash. If it is large amounts, see above. Alternatively, you might contact a restaurant to see if you can add your waste oil to theirs for recycling. The link below also suggests adding it to compost, but I would check out some
As expensive as cooking oil is, filter and reuse is the best way. Restaurants that are careful don’t throw away oil. They filter and reuse and as the oil level drops from going out with the product, they just add more oil. Filter and refrigerate your leftover oil if possible. I have a neighbor who runs his Chevy Suburban deisel on used cookin oil. He just filters it first.
