What are biodegradable lunch boxes?
A biodegradable lunch box is a kind of lunch box that can be degraded by microorganisms (bacteria, mold, algae) in the natural environment under the action of enzymes, a biochemical reaction occurs, and the appearance of the mold changes to the inner quality, finally forming carbon dioxide and water. The entire degradation process can be decomposed into harmless substances without human participation, which is a very long process. In addition to the degradation performance of the "General Technical Requirements for Disposable Biodegradable Catering Utensils", the finished waste of biodegradable lunch boxes should also have recycling value, easy to reuse, or easy to hygienic landfill and high-temperature composting.
2. What are the main components of biodegradable disposable lunch boxes?
Biodegradable lunch boxes are made of two materials: one is made of natural materials, such as paper products, straw, starch, etc., which can be degraded, also known as environmentally friendly products; the other is made of plastic as the main component, adding starch , photosensitizers and other substances.
1. Biodegradable natural material lunch box
Disposable biodegradable lunch boxes made of natural materials are also called biodegradable lunch boxes. The biodegradable lunch box is a relatively advanced environmental protection product. It uses starch as the main raw material, adds plant fiber powder and special additives in the annual growth period, and is processed by chemical and physical methods to make a biodegradable fast food box. Since starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally decomposed into water and carbon dioxide. In addition, the material blended with it is also a completely degradable material, so it can be said that it has no impact on the environment. The main source of starch, the raw material for production, can be annual plants such as corn, potato, sweet potato and cassava. Naturally, biodegradable lunch boxes are not perfect. For example, most of the raw materials for production are food crops, and there are still problems such as mildew resistance that need to be solved.
