Iron filings/shavings in the aquarium?

I work in the service department in a dealership and we are constantly emptying a trash can full of iron shavings from brake rotors in the dumpster. Could these be used in the substrate in a tank or in some manner to fertilize? It just seems like a waste to throw this much iron out every day. Just a thought.

Is it clean? I would assume it would have at the very least grease, brake dust, oil, road grime etc. that would be in there as well.

I agree, even if the iron can be used, it will be awefully dangerous to put in a tank no matter how much you clean it. Automotive chemicals are not easy to clean, or is it good for animals.

Wouldn't it rust? I think plants need iron the element not iron alloys used in automotive. You probably can't be sure that the iron that you are tossing is pure iron....it is probably not.

I'd not do it. If you don't want to waste it you could probably stock up for a year and sell it for scrap metal...Store it under mineral oil and it won't rust.

Unless we are talking motorcycles, bicycles or karts I doubt you have seen steel rotors. Car and truck rotors are cast iron or carbon.

I didn't even think about the other chemicals on the rotor... especially the deposits from the brake pads themselves.

It was just a curious thought. Nothing more.

really? I have never seen a steel rotor on a car or truck. only iron.




OP I wouldn't just because of other contaminants. if they washed them before turning them I would think you would be fine but the chances of you getting the other guys in the shop to scrub rotors first...... slim to none.

what you could do is. get a used rotor. wash it yourself (powerwasher) then have one of the guys turn the heck out of it and take those filings that you know are clean. you can make a buttload of filings from one rotor if you just keep returning it.

wouldnt matter once it rusts its still iron oxide. wether it comes from a car, boat, pan, nail etc. iron oxide is iron oxide.
