First of all, establishing a sound recycling system is the basis for realizing the recycling of pet blister boxes. Special recycling stations are set up in communities, commercial areas, industrial areas, etc., and equipped with professional recycling personnel and equipment to ensure that pet blister boxes can be collected in a timely and effective manner.
Secondly, the classification and treatment of recycled pet blister boxes is a key step. Since pet blister boxes may be mixed with other plastic materials, they need to be finely classified by professional equipment and technology for subsequent reuse.
After classification and treatment, biodegradation treatment should be given priority for degradable PET blister materials to reduce pollution to the environment. This treatment method can ensure that the materials are safely decomposed in the natural environment and reduce the negative impact on the ecosystem.
For non-degradable or difficult to biodegrade pet blister boxes, they can be treated by chemical recycling. For example, the pet blister box is decomposed into monomers such as terephthalic acid (PTA) and bis(hydroxyethyl) terephthalate (BHET) by depolymerization methods such as hydrolysis, alcoholysis, and enzymolysis, which can be reused to produce PET materials.
In addition, physical recycling is also an effective way to recycle pet blister boxes. By crushing, cleaning, melting and other processes, the recycled pet blister boxes are reprocessed into particles or plates, which can be used to produce new packaging materials or other plastic products.
In the process of recycling and recovery, the joint participation of the government, enterprises and the public is essential. The government should introduce relevant policies to encourage and support the recycling and reuse of pet blister boxes; enterprises should enhance environmental awareness, take the initiative to assume social responsibility, and actively participate in recycling and reuse; the public should also enhance environmental awareness and consciously put pet blister boxes at designated recycling sites.
Finally, with the advancement of science and technology and the improvement of environmental awareness, more innovative pet blister box recycling and recovery technologies will emerge in the future, contributing to the construction of a green, environmentally friendly and sustainable development environment.
