The key to knowing whether a material can be recycled often depends on cost. The reason for the high degree of recycling of aluminum products is that the cost of manufacturing new aluminum products is too high, while the cost of using old materials is relatively low. This reduces energy consumption and reduces greenhouse gas emissions into the atmosphere.
