Translated with AI from the Russian original.

Scientists at Perm Polytechnic Institute have developed a technology for recycling laminated foil - a complex multi-layered material that was previously almost never recycled. Foil is used for packaging food, tea, and medicines - it consists of aluminum and a paper base, which are difficult to separate. Previously, it was not recycled.

The technology developed in Perm allows separating the fibrous part from aluminum using a special aerodynamic apparatus - without water or chemicals. The remaining aluminum is removed with a hydrochloric acid solution. The result is fiber suitable for reuse and high-purity aluminum crumb.

The new technology allows using up to 100% of materials, reduces the amount of equipment by half, and contributes to the development of a circular economy - when waste turns into a resource.
