Paper Cups that are Fully Biodegradable
The widely used paper coffee cups are not entirely made of cardboard. The cardboard used for their production is extruded (coated) with a thin layer of polyethylene. The thickness of this layer is about 15–18 microns. Polyethylene is used for two main reasons. The first is to make the cup waterproof. During the cup-forming process, polyethylene acts as a bonding material. Through heat sealing or ultrasound, the layer is heated, and this way the cup is produced in the form we all know.
Although this layer is extremely thin, the cups are not biodegradable. Like any other plastic, this layer would take a very long time to break down. There are already several factories in Europe that have specialized in recycling this type of composite product. However, the collection and transportation of these cups to the appropriate recycling facilities remains a huge challenge for consumers of “on-the-go” drinks.
With the advancement of technology, many factories have started producing cardboard with water-based barrier layers. Cardboard cups made with such material retain their waterproof properties, but they are now biodegradable, recyclable, and home-compostable.
Biodegradable in Nature
Paper cups with a biodegradable barrier layer are a great alternative to all the cups we use in our daily lives. By using this product, you show your commitment to protecting the environment. These cups can be recycled through the already established waste paper streams. The advantage of cardboard cups is that even if they are not recycled, once they end up in nature, they will break down within a few months without polluting the environment. Paper is a natural material, and once in the environment, it becomes food for many microorganisms.
Home Compostable
Paper cups are also suitable for home composting. Try it yourself. Bury a cup in your garden and see what happens after about three months. The cup will be decomposed, if not completely, then at least by 90%.
The paper cups we offer come with an interesting and playful design that inspires awareness of environmental protection. If you would like us to produce cups with your own design, contact us for more information.
