Do you think I should report this company for disposing of wire into the garbage?

I work for a commercial cleaning company. One of the buildings I clean is an office building for an internet provider company. One of the offices is labeled "splicer". When I empty his trash can, I see al sorts of wires. I'm not sure what kind. Possibly fiber optic cables. I read that it's illegal to dispose of those into the trash, or any kind of wire, because its bad for the environmen. I guess I could report the company, but I dont want to because they may know it was me, and then we could lose the contract. Even if we didn't lose the contract, then it would be extremely awkward working their.
