Recycling Silicone Papers

Recycling Silicone Papers

Recycling silicone paper, also known as release liner or silicone-coated paper, can be a complex
process due to the presence of silicone coatings. Silicone paper is commonly used in applications
such as adhesive labels, tapes, and graphic films, where the silicone coating acts as a release agent.
The silicone-coated paper used for food contact applications contains small amounts of silicone
that make the paper resistant to oil, grease, and water. However, the silicone coating makes
recycling paper more challenging.

Recycling technology for silicone paper involves the following aspects:

Collection and Sorting

Silicone paper waste needs to be properly collected and sorted to separate it from other types of paper and packaging materials. This can be done through manual sorting or automated sorting systems that can identify and separate silicone-coated paper based on its characteristics.

Fiber Recovery

Once the silicone coating is removed or reduced, the paper fibers can be recovered for recycling. This involves pulping the de-siliconized paper to break it down into a pulp, which can then be processed to remove contaminants and produce recycled paper fibers.

De-siliconization

The silicone coating on the paper needs to be removed or reduced to a certain extent to allow for further recycling. De-siliconization methods involve chemical treatments and mechanical processes to break down the silicone layer and separate it from the paper fibers.

Treatment of Silicone Waste

The removed silicone waste from the de-siliconization process requires proper treatment or disposal. Depending on the specific composition and regulations, silicone waste needs to undergo further processing, such as chemical treatment, to manage its environmental impact.

Our company there are ongoing efforts to develop more efficient and sustainable recycling
technologies for silicone-coated paper reduce waste and promote circularity within this industry.

Our recycling technology focused on silicone paper recycling works on developing innovative
approaches and equipment to improve the efficiency and effectiveness of the de-siliconization
process, as well as finding applications for the recovered paper fibers. Our collaboration among
stakeholders, including paper manufacturers, adhesive product manufacturers, and waste
management companies, is crucial to driving advancements in silicone paper recycling technology
and establishing a more sustainable approach to its disposal.
