It is reported that not long ago, the Parana Polytechnic Institute in Brazil successfully developed a new method for recycling composite packaging materials, and has filed a patent application. Reinforced packaging made from layers of paper, plastic, and aluminum foil is increasingly used in the packaging of foods and pharmaceuticals. Although reinforced packaging materials have the characteristics of anti-corrosion and strong freshness, their structural characteristics make their recycling a headache. This new separation technology makes it possible to recycle the reinforced packaging material. The school uses a special chemical solvent to recover the three components in the package. After immersing the fortified bag in this solvent for two and a half minutes, the plastic, aluminum, and paper in the packaging material will delaminate. The three layers are then manually separated and the remaining solvent is removed under high pressure. The three substances can be easily separated and recovered. This solvent is quite effective for paper, PVC plastic or polyethylene. This technology is not only suitable for the packaging of recycled milk and juice, but also for thinner packaging such as salt, vacuum coffee and eggs. (Li Feng)
