Scientists at Perm Polytechnic University have developed a technology for recycling laminated foil — a complex multi-layered material that was previously practically not recycled. Foil is used for packaging food, tea, 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 solution of hydrochloric acid. The result is fiber suitable for reuse and high-purity aluminum chips.
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.
