How to dispose of discarded BOPP thermal synthetic paper?

The following methods can be taken to deal with the waste BOPP thermal synthetic paper, which aims to reduce environmental pollution and promote resource recycling:

First, physical recovery and reuse

1.Classification collection: First of all, waste BOPP thermal synthetic paper should be classified and collected with other types of waste to ensure the efficiency and effect of subsequent treatment.

2.Cleaning and crushing: The collected BOPP thermal synthetic paper is cleaned to remove surface stains and residues. Subsequently, a crusher is used to break it into smaller particles or fragments for easy subsequent processing.

3.Granulation regeneration: The crushed BOPP thermosensitive synthetic paper particles are sent into the extrusion granulation equipment, and processed into recycled plastic particles by heating melting, extrusion molding and other processes. These recycled particles can be used as raw materials to re-use in the production of BOPP films or other plastic products to achieve resource recycling.

Second, chemical recovery method

Although chemical recycling has not been widely used in waste plastic treatment, it is possible to use chemical recycling for certain types of waste plastics such as BOPP thermal synthetic paper in the future. The chemical recovery method mainly decomposes waste plastics into small molecular compounds or monomers through chemical reactions such as cracking and catalytic decomposition, and then is used to produce new chemical raw materials or fuels. However, this approach requires high technical and financial investment and is still in the research and development stage.

Third, energy recovery

If the waste BOPP thermal synthetic paper cannot be directly recovered physically or chemically, it can also be considered to be disposed of by means of energy recovery. Energy recovery is mainly the use of waste plastic as fuel, through combustion and other ways to convert it into heat or electricity. However, it should be noted that this method may produce some environmental pollution, so it is necessary to take corresponding environmental protection measures when implementing, such as waste gas purification treatment.

Fourth, other processing methods

In addition to the above three main processing methods, other processing methods can be taken according to the specific situation. For example, waste BOPP thermal synthetic paper containing sensitive information or requiring confidential treatment can be disposed of by crushing and destroying; For a small number of waste BOPP thermal synthetic paper or difficult to centrally treat, it can be considered to be directly sent to the waste treatment plant for harmless treatment.

Matters needing attention

When dealing with waste BOPP thermal synthetic paper, the following points need to be noted:

Ensure that the processing process complies with the relevant national and local laws and regulations;

As far as possible, choose environmentally friendly and efficient treatment methods to reduce environmental pollution and waste of resources;

Strengthen the classification of waste collection and management, improve the recycling rate;

Pay attention to the development and application of new technologies and new methods, and constantly improve the disposal level of waste BOPP thermal sensitive synthetic paper.

To sum up, the disposal of waste BOPP thermal synthetic paper needs to consider a variety of factors, take a scientific and reasonable treatment, in order to achieve the dual goals of resource recycling and environmental protection.
