A compostable paper cup must degrade within 12 weeks, under commercial composting conditions and the international standard that you must achieve to be able to call your compostable paper cup is EN13432. Normal cups are made using cupboard that comes from wood pulp and a fine lining of polyethylene (PE) on the inner wall, which ensures that when the cup is produced it is then watertight, but they do not compost. To make a compostable paper cup you have to use other methods of manufacturing, but at the same time make sure the compostable paper cup is functional in the same way as the normal PE cup is.

The life cycle of this compostable paper cup can be generally divided into five sections: gathering materials, making paperboards, coating the paperboard, shaping the paperboard, disposing the product.
The first step of making compostable paper cup is to gather raw materials. The raw material used for making the paperboard is virgin woods. The thinner section of the trunks is the part used to make pulp for paper and paperboard production. Deciduous broadleaved trees would be used to make paperboard. The reason is that they have short fibers. The other material required for making compostable paper cup is corn. The corn is the main material for the plastic coating of the cup.
The second section is to produce the paperboard of compostable paper cup. The first step to make the paperboard is to make pulp. There are two methods to make the pulp for paperboard, the chemical pulp and the mechanical pulp. The method used for producing compostable paper cup is chemical one, which can produce products with higher strength. Furthermore, before the pulp is dry, it should be bleached. The next step is to press the pulp. The pulp would be moved from the web and be compressed by two rolls, which is aimed to preliminary smoothen the surface and dehydration. Then the paperboard would be further dehydrated in next several sections and also be glazed the surface.
The next section is to shape the cup. The coated paperboard will be put into a machine. The machine would first print patterns on the paperboard if required. Then the paperboard would be cut into two shapes. One is fan-shaped, which is the cup wall, and the other one is circle, which is the bottom of the cup. Then the curved cup-fan-wall-paper would be sealed with the cup bottom. After that, the machine will knurl the cup bottom and the products to collectors. After this step, the manufacture of the compostable paper cup is finished.
If compostable paper cups are sent to an industrial-scale composting facility, compostable paper cups will break down in less than two months. In someone’s backyard compost heap, compostable paper cup could easily take more than a year. If compostable paper cups are accidentally sent to a landfill and buried, it could take over a century. And if compostable paper cups go into a plastics recycling bin, they will contaminate the recycling process.
The vast majority of compostable paper cups are indistinguishable from clear plastic, recyclable cups, other than being marked with a big green stripe. They are the same size and shape, holding liquids the same way, and no ordinary consumer would have any reason to guess that they are different. If anything, compostable paper cups might look at the green stripe as a reminder that plastic should be recycled!
Guest after another will toss compostable paper cups into the plastics recycling bin. The compostable paper cups would be harmful to the recycling process, which is set up to recycle oil-based plastics. The converse is also true that plastic cups should not be put into the composting bins. Despite a well-educated crowd and great signage at the restaurant, there was a great deal of confusion, and from my observations, most were guessing wrong.
Avoiding plastic: Today, environmentalists are encouraging the public to use green products everywhere they go, instead of just at home. At the same time, more food and beverage container companies are finding unique ways to create eco-friendly dishes and utensils. Foodservice industries that serve drinks to customers can make a huge impact toward protecting the environment by switching over to compostable paper cups rather than using plastic containers.
Protecting health: The public is also aware that compostable paper cups protect the environment in other ways besides reducing trash in landfills. Food and beverage containers made from compostable materials do not contain petroleum products that are toxic to plants and animals. Petroleum is an expensive ingredient used to make plastic utensils and plates that increase the overall price of a beverage or food sold in a restaurant. Recent studies have revealed that the chemicals in plastics leach into beverages and foods before entering the human body during consumption.
Increasing business: By implementing compostable paper cups into your inventory for drink containers, you will be not only helping the environment, but also creating a great impression for your business and its consumers. Modern consumers are frequently choosing to buy products at businesses that care about the earth’s environment. Selling foods and beverages in containers made from natural materials such as sugarcane, paperboard, or plant fibers is an excellent way to increase a business’s customer base.
