Aluminum, despite its strong corrosion resistance, produces...Huangpu District Scrap Machinery RecyclingBut extracting oil in the atmosphere also experiences varying degrees of corrosion. When it undergoes refining with certain chemicals like alkalis, seawater, and soil, it can trigger strong or violent chemical reactions, consuming vast resources and causing pollution. The pollutants and energy emitted during the recycling of used aluminum are significantly less than those from the production of primary aluminum, resulting in much lighter environmental impact and pollution levels, roughly only 10% of the latter. Thus, the recycling and regeneration of used aluminum is a contemporary "green project" that benefits both present and future generations. The first step is to sort the materials.
