Compact discs (CDs) primarily contain polycarbonate plastic, which is derived from petroleum, a non-renewable resource. Additionally, the reflective layer of CDs is often made from aluminum, another non-renewable resource, as its extraction involves mining. Other materials, such as dyes used for data storage, may also originate from non-renewable sources. Overall, the production of CDs relies on various non-renewable resources, contributing to their environmental impact.
