I am living in Chicago area and I had some DIY maintenance work done myself for my car. I got some waste fluids that I do not know where to dispose. They are the bake fluid and the power steering fluid. But I do not know where to send it to since I am not supposed to dump in the drain or pour them in to a garbage can or just dump it outside house.

I want to take my septic gasses and manure gasses and turn them into renewable energy on my property to power up my home. How do I do that?
Are there residential systems designed to do this?
