プラスチックフリーの紙コップの原料を使用

スマートで革新的で 100% リサイクル可能なアイデアが現在、通常のプラスチック層なしで紙カップを作成するために使用されています。プラスチックを使用しない紙コップを製造する際の主な問題は、常に液体を含むことができるコーティングを作成することでした。そのため、プラスチックが主コーティングとして使用されてきました。しかし、ここで紙コップの最新の革新的な開発が登場します。

プラスチック層でカップを製造する代わりに、現在では、水ベースの分散コーティングを使用して、カップの内側に効果的なバリアを形成し、カップに液体を入れることができるようにしています。プラスチックを含まない紙コップの主な資源は樹木パルプであり、これを化学物質と混合し、水溶融器に入れて薄い層を形成します。水分が乾燥すると、パルプに付着している層が液体を含むことができるバリアを形成します。パルプは新しく製造され、リサイクル材料から作られていないため、この層には液体が含まれる可能性があります。

製品の使用方法

The plastic-free paper cups are like normal paper cups mainly used by cafes, restaurants, and hotels. They can be used in all the same occasions as standard paper cups, since they can contain both cold and hot liquids. The plastic-free paper cups have the same restrictions regarding alcohol as normal paper cups, which means they cannot contain strong alcohol and should not contain drinks with more than 5% alcohol. Paper cup manufacturers specify that the cups can be used to serve beer without foaming too much.

Plastic-free paper cups and their compostability

When it comes to plastic-free paper cups and their compostability, there are ongoing tests to make sure that they’re compostable when thrown in nature. Most reports confirm that they are compostable, but to make sure, they must be under temperature conditions of 20-30 Celsius. If they’re under that temperature, it will take them 26 weeks to decompose. In this case, they should be sent to composting facilities to make sure they are decomposed in a proper way. No matter what, we of course do not recommend that you throw the paper cups in nature.

Plastic-free paper cups and their recyclability

Paper cups are manufactured from virgin wood fibers and other relevant chemicals which in general makes it easier and more available for recycling technologies to complete the recycling process without any problems. New pulp can easily be recycled to other paper products and be repulped even up to seven times. Of course, when recycled more than seven times, it will not have the same quality. It is also important to note that while the plastic-free paper cups are recyclable, they cannot be used to produce other food packaging products, since recycled paper is not allowed to be used for food contact materials.

The plastic-free paper cups are designed to be easily recycled and repulped so all recovery fiber facilities that process carton-board products, can process them without any problems. All paper board produced with plastic-free paper is proven to be recyclable and repulpable in conventionally recovered fiber facilities. So, the cups should be collected with other recyclable materials such as newspapers, magazines, etc.

Since the paper cups can be recycled in normal recycling facilities, this creates an efficient recycling system and process. Food service companies using wood fiber-based cups can then improve their environmental footprint easily with plastic-free paper cups. If the goal is to create a business model where customers can be a part of collecting paper cups, the recycling process should be easy.
