What should I pay attention to for environmentally-certified tableware?
Biological or natural degradation has become one of the development trends of disposable products. Tableware distribution, as a stable industry, more and more people are making disposable tableware. Facing the policy of using easily recyclable or degradable disposable tableware, many people don't know how to choose. The following focuses on the profits of processing degradable disposable tableware, To analyze the operability of these two products.
The research and development of degradable products has also been for some years. At present, degradable disposable tableware includes paper, starch, plant fiber, photosensitive plastic, etc. at present, there are still some problems to be solved for these technical products. First, the practicability of these products needs to be further strengthened, the safety supervision of added auxiliary agents needs to be strengthened, and there are generally poor waterproof It is easy to damage and deform and is not resistant to high temperature. Secondly, in addition to paper, the production cost of products is generally high, which also leads to limited profits. After all, as a fast-moving consumer goods, one basis for winning is price. Compared with the price of easily recyclable crystal tableware, there is a gap in profits.
In addition to considering the profit of processing degradable disposable tableware, the subsequent treatment of the product is also a problem. Many materials need to be degradable in a suitable environment, such as temperature, humidity, whether they need to be buried, whether they need to cultivate microorganisms, etc., which requires the provision of corresponding sites and preconditions, which undoubtedly increases the cost of centralized recovery and treatment, It also wastes some resources, and the easily recycled crystal tableware as waste can be processed into industrial products such as automobile lampshade and mobile phone shell after crushing and granulation, so as to continue to give full play to its socio-economic value.
The explanation of degradability is that under certain conditions, articles undergo biochemical reaction to form simple compounds. One view is that only the degraded products decomposed into carbon dioxide or water can be called degradation. Obviously, many materials do not meet this condition. Even our common paper cups have wax coating, plasticizing layer and other substances that cannot be degraded, Many so-called degradable materials actually have very harsh degradation conditions and need special treatment sites. Under natural conditions, the degradation time is long, and the formed substances also contain a large number of harmful components.
In addition, the concept of environmental protection products includes many categories such as reusable, renewable and degradable, and does not specifically refer to degradable. For example, in the category of environmental protection tableware, degradable tableware is facing the problems of poor waterproof, nonstandard wax coating and plasticization, low adaptability and high production cost, which has always limited the promotion of products, Renewable products such as crystal tableware have become the mainstream of the disposable tableware market because of their beautiful appearance, high temperature resistance, non-toxic and odorless, high recycling value and reprocessing into industrial products.
