The environmental advantages of waste aluminum recycling are very obvious compared to primary aluminum production. Three million tons of recycled aluminum will reduce carbon dioxide emissions by 30 million tons, and the energy required for recycling and recycling aluminum scrap is only 5% of the energy required for primary aluminum production. Therefore, the waste aluminum recycling industry is not only beneficial to environmental protection, but also to a large extent sustainable development. Waste aluminum recovery and regeneration technology also minimizes environmental impacts due to the consideration of investment in environmental protection. In Europe, there are overall EC pollution prevention laws and control regulations. Environmental legislation has reduced the impact of the processing industry on the environment and has also provided regulations to reduce the impact of the transportation industry on the environment.

In the 15 years before 1997, European cars were legislated from the aspects of weight reduction, aerodynamics and safety-related combustion efficiency, low emissions, low noise, and greater user demand for passenger comfort, resulting in a 28% increase in fuel efficiency. The quality of the car largely compensates for the efficiency and reduces the car's running resistance. Fuel efficiency increased from an average of 7.11 litres/100km in 1983 to 6.61 litres/100km in 1997. Cast aluminum contributes significantly to the weight reduction per car. The amount of aluminum per car increased from 30 kilograms in 1978 to an average of 110 kilograms per car in 2008. If considering the indicators that have been reached now and what indicators can be achieved in the future, reducing weight of cars is an important choice for future fuel efficiency. A car with a weight reduction of 100 kilograms can reduce and reduce carbon dioxide emissions by 8 grams per kilometer, while the automotive industry's target is to achieve a reduction in carbon dioxide emissions of 140 grams per kilometer in 2008. Aluminum is an important material for automotive fuel improvements and will Increasingly important. The global demand for aluminum has been steadily increasing for 40 years. As aluminum has advantages as an engineering material, it seems to continue to grow in the foreseeable future. Aluminum is very important for improving fuel efficiency and reducing carbon dioxide emissions. The use of scrap aluminum as a raw material, its increase will be due to new production activities or the life of these materials and products, but the production of aluminum scrap will not be stimulated by the demand for growth, because aluminum scrap can not grow like a tree can grow It is also impossible to mine an aluminum scrap mine. In fact, when processing new products, the design of their performance has made every effort to reduce the generation of aluminum scrap and increase the useful life. If the global aluminum service life grows at an annual rate of around 6%, the world will face long-term reduction of aluminum scrap. Aluminum scrap is a raw material for the secondary aluminum processing industry.

An inherent problem with aluminum as a successful material is that supply falls short of demand, and its normal economic effect is that before the supply of aluminum meets demand, the price of aluminum products will increase, and demand will be safeguarded by the increased use of primary aluminum. The European secondary aluminum processing industry will face a potentially unstable market, which will threaten the survival of the European secondary aluminum processing industry.
