Alright...HERE is the answer!!!! DO NOT run it down the sink. DO NOT throw it away in a can/jar!!!! Find a local restaurant that has a grease trap. ALL restaurants that have fryers have one...ITS THE LAW!!!. These restaurants sell this grease to buyers that recycle it. They make dog food, cat food, MAKE-UP!!!! (knew that would get cha!!!)
I worked in a restaurant for 18 years...we welcomed people to throw their grease in the "pit". That same restaurant can usually supply you with a gallon (used) pickle jar, jalapeno jar, etc. Fill it, (will probably take you months) then empty into the recycling grease pit. The restaurant wins, the buyers win, the dog food companies win, make up wins, the ENVIROMENT wins!!!!
I will have to say, find a "mom and pop" place. Get yourself a bucket and save the planet!!!!
For anyone who is wondering what I am talking about, these "pits" are usually placed in the back of a restaurant. They are generally a black, welded box with a lid on the top. The lids are almost ALWAYS pad-locked. This is to keep THEFT from happening. Yes, THEFT. These buyers pay high dollar for that grease....that is why most places will take it. I know I did as a restaurant manager.
P.S. This is also the same grease that fuels some cars...you know, the so-called "french fry" fueled cars?
