Recyclability Of Aluminum Foil Packaging

- Nov 06, 2019-

Aluminum materials are fully recyclable and endless, with no loss of quality during the recycling process. The collection, recycling and recovery of aluminum foils has increased, which means that the amount of primary aluminum required in the industry will be less and less. This will result in significant savings in energy consumption during the aluminum smelting process, as the energy required to process the recovered aluminum is 95% lower than the energy required for the same amount of primary aluminum (electrolytic aluminum). The amount of aluminum recovered depends to a large extent on the efficiency of the national packaging collection system. In Europe, the average recovery rate of all aluminum packaging is above 60%, and the recovery rate of aluminum foil containers has exceeded 55%. Even if the aluminum foil package is not separated and recycled, a large portion of the aluminum content of the waste packaging containing aluminum foil can be recycled from the bottom ash of the incinerator when it enters the waste incineration power generation system. During the incineration process, the oxidized aluminum releases energy, which is converted into heat and electric energy to improve power generation efficiency. The recovery of aluminum from the bottom ash after waste incineration has enormous recycling potential. Currently in Europe, the recycling ratio of this part of aluminum is: aluminum foil: 40+%, composite packaging: 50-75%. The industry believes that more aluminum will be recovered from the bottom ash after incineration in the future.

There are three key steps to working to achieve the highest recovery rates for all aluminum packaging. The first is to collect all the aluminum packagingin the consumer side, pay attention to separate from the domestic garbage, and also recycle the used flexible packaging. The second step is the centralized sorting of waste. With the prior art, the recovery of the aluminum containing portion of the package is as high as 96%, which is technically and economically feasible. The third part is smelting recovery. In the above three steps, the classification and recycling of scrap aluminum packaging is the most important. It can be said that there is no collection, no recycling! We learned that Shanghai, China has begun to implement waste separation and recycling, and more than 30 other cities will also carry out mandatory waste separation and recycling, which is good news for aluminum packaging and recycling of all aluminum materials. It will be a great manifestation, which also indicates that aluminum packaging will usher in even greater opportunities.

At present, the global society and many countries have begun to pay attention to reducing the use of plastic (7245, -45.00, -0.62%) packaging to protect the marine environment, especially in the fast food and food delivery industry to limit and reduce the use of disposable plastic tableware. This pair of aluminum foil will usher in another big market opportunity. Expanding the use of aluminum foil containers and developing aluminum foil packaging materials to replace plastic packaging has become a hot spot in the industry.
