Magnesium alloy processing generates large amounts of scrap, such as chips and offcuts. Traditional recycling methods are inefficient, energy-intensive, and prone to quality degradation. The research team innovatively adopted a "low-temperature melting + gradient purification" process route, effectively removing impurities while preserving the original properties of the magnesium alloy. Testing shows that the recycled magnesium alloy exhibits mechanical properties comparable to primary magnesium and can be widely used in structural component manufacturing for automotive, 3C, and other fields.
According to estimates, adopting this technology can reduce carbon dioxide emissions by approximately 20 tons and save about 80% of energy consumption for each ton of magnesium alloy scrap recycled. Against the current "dual carbon" goal background, green recycling of magnesium alloys not only brings significant economic benefits but is also a key measure to enhance the sustainable development capacity of the industry.
The research team stated that next step they will promote the integrated application of this technology with existing magnesium alloy processing production lines, establishing a closed-loop industrial chain of "raw materials - processing - recycling -rebirth"At the same time, the team will conduct lifecycle assessment research on magnesium alloys, providing scientific data support for the green attributes of magnesium alloys.
