What is a biodegradable meal box?
Biodegradable lunchbox refers TO THE LUNCHBOX THAT CAN UNDERGO biochemical REACTIONS UNDER THE ACTION OF MICROORGANISMS (BACTERIA, mold, ALGAE) in the natural environment, resulting in appearance mildew to internal quality change, and eventually form carbon dioxide and water. The whole degradation process can be broken down into harmless substances without manual participation, which is a very long process. In addition to meeting the degradation performance of GB18006.3-2020 "General Technical Requirements for Disposable Degradable Food and Beverage Utensils", the finished waste of degradable meal boxes should also have recycling value, be convenient for recycling, or be convenient for sanitary landfill and high-temperature composting treatment.
2. What are the main ingredients of degradable disposable meal boxes?
Degradable meal boxes use two kinds of materials: one is made of natural materials, such as paper products, straw, starch, etc., degradable, also known as environmental products; The other is plastic as the main component, adding starch, photosensitizer and other substances made.
1, degradable natural material lunchbox
Disposable degradable meal boxes made of natural materials are also known as biodegradable meal boxes. Biodegradable meal box is a kind of advanced environmental protection product. It takes starch as the main raw material, adding annual plant fiber powder and special additives, through chemical and physical methods to make biodegradable fast food box. As starch is a biodegradable natural polymer, it is decomposed into glucose and finally water and carbon dioxide under the action of microorganisms. In addition, the material blended with it is also fully degradable, so it can be said that it has no impact on the environment. The main source of raw material starch production, can be corn, potato, sweet potato, cassava and other annual long-term plants. Naturally, biodegradable meal boxes are not perfect, for example, most of the production of raw materials are food crops, and there are mildew and other problems to be solved.
2. Degradable plastic meal box
The manufacturing material of this kind of disposable meal box is degradable plastic. The so-called degradable plastic is to add a certain amount of additives in the production process of plastic, such as photosensitizer, starch and other raw materials. In this way, after being used and left in the wild for three months, the degradable plastic product can be broken down into pieces from its complete shape, thus improving the environment at least visually. But the biggest drawback of this technology is that the debris does not continue to degrade, merely turning from large pieces to small pieces of plastic, which are not fundamentally up to the task of eliminating white pollution.
