What is a biodegradable lunch box? What are the main ingredients of the biodegradable disposable lunch box?

Now that environmental protection is being promoted everywhere, takeaway businesses are gradually replacing ordinary disposable lunch boxes with biodegradable tableware to reduce takeaway pollution. This is where the question arises: what is a biodegradable lunch box? What are the main components of biodegradable disposable lunch boxes? Biodegradable disposable lunch boxes are tableware that can degrade into carbon dioxide and water. One type of material used in biodegradable lunch boxes is made from natural materials; the other type is made from plastic with starch, photosensitisers and other substances. to make them. Next, more details about biodegradable lunch boxes will be given.

What is a biodegradable lunch box?

What is a biodegradable lunch box?
 
Degradable lunch box refers to a lunch box that can undergo a biochemical reaction under the action of natural environment microorganisms (bacteria, molds, algae) enzymes, causing the appearance of mildew to the internal quality change, and finally the formation of carbon dioxide and water. The entire degradation process can be decomposed into harmless substances without human involvement, which is a very long process. In addition to the degradability of the degradable meal box product waste in accordance with GB18006.3-2020 "General Technical Requirements for Disposable Degradable Tableware", it should also have recycling value, be convenient for recycling, or be convenient for sanitary landfill and high-temperature composting. .

What are the main components of the biodegradable disposable lunch box?
 
Biodegradable lunch boxes use two kinds of materials: one is made of natural materials, such as paper products, straw, starch, etc., which are biodegradable and are also called environmentally friendly products; the other is made of plastic as the main component and added starch , Photosensitizer and other substances.
 
1. Degradable natural material lunch box
 
Disposable degradable lunch boxes made of natural materials are also called biodegradable lunch boxes. The biodegradable lunch box is a relatively advanced environmentally friendly product. It uses starch as the main raw material, adds annual plant fiber powder and special additives, 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 fully degradable material, so it can be said that it has no impact on the environment. The main source of raw material starch can be corn, potatoes, sweet potatoes, cassava and other annual-growing plants. Naturally, biodegradable lunch boxes are not perfect. For example, most of the production materials are food crops, and the problems of anti-mildew have yet to be resolved.
 
2. Biodegradable plastic lunch box
 
The raw materials for this type of disposable lunch box are degradable plastics. The so-called degradable plastics are the addition of a certain amount of additives, such as photosensitizers, starch and other raw materials during the plastic production process. In this way, the degradable plastic products can be broken down into fragments from the complete shape after being used and discarded and exposed to nature for three months, thus at least visually improving the environment. But the biggest drawback of this technology is that these fragments cannot continue to be degraded. They only turn from large pieces into small pieces of plastic, and are not fundamentally competent for the task of eliminating white pollution.
