I believe you are asking about finding scraps of metal and plastic in your oak leaf compost that you retrieved from a public source. My suggestion is to remove the compost and start over with something fresh. I would also contact the agency or source of the compost to report the problem. It would take years for these materials to break down in the soil, so it's probably best to remove them altogether.
