Disposable tableware has many hidden dangers. First of all, about paper tableware. Some underground factories use non-food grade paper to process tableware; Paper tableware generally uses adhesives, and some underground factories often use impurities or toxic adhesives, and even use industrial adhesives; When printing words on tableware, the ink should be food-grade enough, but some underground factories often use industrial ink, which can easily penetrate into the inner wall of paper tableware and endanger health. Secondly, about plastic tableware. According to the national regulations, the main materials for making plastic products that can hold food are polypropylene, polyethylene, polyvinyl chloride and polystyrene. These raw materials are below 85 degrees Celsius, and there is basically no problem. However, at high temperature, some disseminated substances will be produced, and monomers such as benzene will be dissolved. Third, about disposable chopsticks. Its materials mainly include composite materials, logs and bamboo. The composite material is made of some scraps and processed into powder, and then compounded, and its adhesive will release toxins when it meets high temperature. In Lanzhou alone, the disposable chopsticks consumed every day are1500,000 pairs, and 20,000 trees are "eaten" every year. Because of its cheapness, it is popular to enter middle and low-grade restaurants, hot pot restaurants and snack stalls in urban areas. Most of the tables are cheap disposable chopsticks. If consumers want to use chopsticks with slightly better quality or sterilized chopsticks, they can only go to a few restaurants or high-grade dining places. Each pair of chopsticks is only 0.02 yuan, but because the cost of chopsticks is included in the cost, it is provided to consumers free of charge, so the price is the first. In order to make money, operators of course choose chopsticks that are shoddy but cheap. As we all know, one of the killers of disposable tableware entering the market is its low price. There are three main types of tableware: foamed lunch boxes, plastic bowls and cups, paper cups and paper bowls, and their wholesale prices are not much different: plastic bowls are 8 cents each, and the retail price is 1 corner each; Plastic cups, paper bowls and cups cost five or six cents each, and the prices are very low. For many years, there has been a misunderstanding. That is to say, mass production of convenient chopsticks in China is trampling on the environment and disrespecting nature. It is the embodiment of quick success and instant benefit. In fact, this view is one-sided. The main raw material of disposable chopsticks is fast-growing wood such as fast-growing poplar. The plan of "Returning Farmland to Forests" vigorously promoted by the China Municipal Government is essentially the promotion of fast-growing tree species. Fast-growing tree species are chosen because their growth cycle is short, and they can be planted in a large area in a short time. If ordinary tree species are used, the growth cycle is long, which not only fails to achieve the purpose of "afforestation", but also affects the economic interests of farmers in a short time. In many places, many things have happened because farmers can't get practical benefits. It is conceivable that the effect of "returning forests" can not be achieved. From a macro point of view, the production of disposable tableware still has advantages and disadvantages.
