In recent years, with the promotion of sustainable development strategies and the challenging task of environmental protection, more and more people have started to adopt a green and environmentally friendly lifestyle. From small actions like low-carbon transportation and the "one kilometer" initiative to larger measures like plastic reduction, the aim is to reduce pollution caused by white garbage. The four aspects of clothing, food, housing, and transportation have been intertwined throughout the development of humanity, with food safety being one of the major concerns in recent years due to various related issues, such as serious waste and pollution. What if used utensils could be absorbed by the earth, recycled and reused, and thus prevent pollution from further harming the earth? This is where the idea of disposable biodegradable tableware came from.
Disposable biodegradable tableware is an advanced type of environmentally friendly product
It mainly uses starch as the main raw material and adds annual plant fiber powder and special additives. After undergoing chemical and physical treatment, it becomes a biodegradable fast-food box. Since starch is a naturally biodegradable high polymer that decomposes into glucose and finally into water and carbon dioxide through the action of microorganisms, it has no impact on the environment. The main source of raw materials for the production of starch can be annual plants such as corn, potatoes, sweet potatoes, and cassava.
Compostable food packaging refers to disposable tableware that can be degraded by microorganisms (such as bacteria, fungi, and algae) and enzymes in the natural environment, which leads to changes in its appearance and inner quality until it eventually becomes carbon dioxide and water. The materials used in the production of such tableware can be classified into two categories: natural materials such as paper products, straw, and starch, which are biodegradable and are also known as environmentally friendly products; and materials made primarily of plastic with added starch and photoinitiators. When people talk about disposable biodegradable tableware, they usually refer to the environmentally friendly products.
Disposable biodegradable tableware is made from plant fibers
Such as sugarcane, wheat straw, bamboo, and reeds. These raw materials are processed into pulp and then molded into shape through vacuum suction, followed by drying. Then, high-tech scientific and technological treatment is applied, and food-grade waterproof and oil-proof additives are added before undergoing deep processing to produce disposable biodegradable tableware that can replace plastic. Due to its ability to be recycled, composted, harmless, and absorbed by soil, it is known as environmentally friendly tableware.
We now know that the materials used in disposable biodegradable tableware mainly come from natural plants. Today, we often see disposable biodegradable tableware made from sugarcane pulp and wheat straw, using the waste from sugarcane and straw, which are easily biodegradable and can ferment and be absorbed by soil during degradation. Usually, it takes about three to four months for them to completely biodegrade, which is an acceptable type of environmentally friendly tableware.
