What are the ways to recycle and reuse discarded BOPP colored synthetic paper?

The recycling methods for discarded BOPP (biaxially oriented polypropylene) color synthetic paper mainly include the following:

1、 Material recycling and reuse

Direct recycling and reuse

For the scraps, defective products or BOPP colored synthetic paper that has been used but still kept clean during the production process, they can be directly recycled and sent back to the production line for reuse.

After appropriate processing such as cleaning, crushing, plasticizing, etc., these materials can be mixed with new materials for the production of new BOPP colored synthetic paper or other plastic products.

Modified Recycling and Utilization

For BOPP colored synthetic paper that has been used and contaminated to some extent, it can be recycled through modified recycling technology.

This usually involves pre treating discarded synthetic paper by cleaning, crushing, drying, etc., and then modifying it through chemical or physical methods to improve its processing and physical properties.

The modified material can be used to produce various plastic products, such as plastic parts, packaging containers, etc.

2、 Thermal energy recovery

For BOPP colored synthetic paper that cannot be directly recycled, it can be converted into heat energy through incineration.

The heat generated during the incineration process can be used for purposes such as power generation or heating, thereby achieving energy reuse.

It should be noted that effective flue gas treatment techniques should be adopted during the incineration process to prevent secondary pollution to the atmosphere.

3、 Developing new recycling technologies

Currently, some technology companies are developing new recycling technologies for BOPP colored synthetic paper.

For example, the technology of crushing discarded synthetic paper into powder and mixing it with other papers to make new paper. However, this technology is still in the experimental stage and faces issues such as high production costs and complex processing procedures.

With the advancement of technology and the improvement of environmental awareness, it is believed that more efficient and environmentally friendly recycling technologies will be developed in the future.

4、 Landfill treatment (not preferred)

Although landfilling is a simple treatment method, due to the slow degradation rate of BOPP colored synthetic paper in natural environments, landfilling may occupy a large amount of land resources and potentially pollute soil and groundwater.

Therefore, landfilling is usually not the preferred method for disposing of discarded BOPP colored synthetic paper.

In summary, the recycling methods for discarded BOPP color synthetic paper mainly include material recycling, thermal energy recovery, and research and development of new recycling technologies. In practical operation, appropriate recycling methods should be selected based on the specific situation and recycling conditions of the waste to achieve maximum resource utilization and environmental protection.
