V. Recyclable biodegradability of ice cream paper cups
Wood pulp paper can be recycled and has degradability. This greatly improves the recyclability and biodegradability of ice cream cups.
After a long period of development, a typical way to decompose ice cream paper cups is as follows. Within 2 months, lignin, Hemicellulose and cellulose began to degrade and gradually became smaller. From 45 to 90 days, the cup almost completely decomposes into small particles. After 90 days, all substances are oxidized and transformed into soil and plant nutrients.
Firstly, the main materials for ice cream paper cups are pulp and PE film. Both materials can be recycled. Pulp can be recycled into paper. PE film can be processed and made into other plastic products. Recycling and reusing these materials can reduce resource consumption, energy consumption, and environmental pollution.
Secondly, ice cream paper cups have biodegradability. Pulp itself is an organic substance that is easily decomposed by microorganisms. And degradable PE films can also be degraded by microorganisms. This means that ice cream cups can naturally degrade into water, carbon dioxide, and organic matter after a certain period of time. So, it basically does not cause pollution to the environment.
Recyclable biodegradation is of great significance for environmental protection. With the increasingly serious global environmental problems, sustainable development has become a topic of common concern for all sectors of society.
In the field of food packaging, recyclable and biodegradable materials are the future development direction. Therefore, promoting recyclable and biodegradable food packaging materials is of great significance for the development of the industry and the environmental protection industry.
