Poly(vinyl alcohol) (PVOH, PVA, or PVAl) Recycling
Properties of Poly(vinyl alcohol)
Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. PVOH has excellent film-forming and adhesive properties, making it ideal for use in the production of films and adhesives. PVOH is also highly resistant to oils, greases, and organic solvents. It is commonly used in a variety of applications such as packaging, textiles, and coatings.
Applications of Poly(vinyl alcohol)
PVOH is a versatile polymer that finds a wide range of applications in different industries. In the food industry, it is widely used as a packaging material due to its exceptional barrier properties against moisture and oxygen. The film formed by PVOH can also be used as an adhesive layer for different types of films, making it a crucial component in flexible packaging. Additionally, PVOH is used in the production of laundry detergent pods, where it serves as a water-soluble packaging material that dissolves in water during the washing cycle.
In the medical industry, PVOH is used to create water-soluble films for blister packaging of medications, which prevents moisture from degrading the contents of the package. It is also used in medical textiles and surgical dressings. PVOH is used as a binder in the production of gypsum-based products in the construction industry, providing excellent adhesion properties, which result in a more robust and long-lasting end product. In the agricultural industry, PVOH is used in seed coatings and for slow-release fertilisers.
Poly(vinyl alcohol) Recyclability
PVOH is a recyclable material, and the recycling process involves dissolving it in water to break down its molecular structure, which makes it more manageable to separate from any impurities present. The resulting solution is filtered, and the PVOH is then regenerated by removing water from the solution. The regenerated PVOH can be used to produce a wide range of products, such as compostable bags, water-soluble films, and adhesives.
The recycling of PVOH is essential for reducing the amount of plastic waste in the environment and conserving resources. Additionally, PVOH is biodegradable, which means that it can be broken down by microorganisms and eventually decompose into natural compounds. Therefore, recycling PVOH not only reduces waste but also has a positive environmental impact by reducing the amount of plastic waste in landfills and oceans.
