Scrap consists of recyclable materials left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Resources Scrap prices may vary markedly over time and in different locations. Prices are often negotiated among buyers and sellers directly or indirectly over the Internet. Prices displayed as the market prices are not the prices that recyclers will see at the scrap yards. Other prices are ranges or older and not updated frequently. Some scrap yards' websites have updated scrap prices.
