While aluminum siding is lightweight and durable, there are environmental concerns associated with its production and disposal. The manufacturing process is energy-intensive and can emit greenhouse gases. Additionally, the extraction of bauxite, the primary source of aluminum, can lead to deforestation and habitat destruction. At the end of its life, aluminum siding can be recycled, which is beneficial, but improper disposal can still contribute to landfill waste. The environmental impact depends on the lifecycle management of the material, including responsible production, use, and recycling practices.
