Purpose and significance

1. Improve students' environmental awareness through investigation, thus reducing the use of disposable tableware, protecting the environment and ensuring people's health.

2. Improve students' interpersonal skills, organization and coordination skills.

Understand the influence of disposable tableware on human body by consulting information;

1, damage to respiratory function: disposable chopsticks must be fumigated with sulfur during the production process, and SO2 will be released when heated during use, which will corrode respiratory mucosa;

2. Digestive function is impaired: disposable chopsticks are bleached with hydrogen peroxide in the production process, which is corrosive and causes corrosion to the mouth, esophagus and even gastrointestinal tract; If talcum powder is used in the grinding process, it will accumulate slowly in the human body and cause gallstones.

3. Bacterial infection: The shelf life of sterilized disposable chopsticks is as long as 4 months. Once the shelf life has passed, it is likely to bring staphylococcus aureus, Escherichia coli and hepatitis.

Through the understanding of roadside shops, snack bars and small restaurants:

1. Most citizens believe that it is the obligation of the store to provide hygienic and clean tableware for customers to eat in restaurants, and it is meaningless to ask customers to pay extra.

2. Some citizens also said that if you don't use disposable sterilized tableware, you may use unsterilized tableware provided by hotels, especially some small and medium-sized restaurants. To this end, some consumers still tend to use disposable sterilized tableware.

Merchants reflect:

Most shops are willing to keep disposable tableware. According to the general manager of a restaurant, although they bring their own sterilized tableware, the level of consumers is different. Some customers choose to use disposable disinfection tableware, and it is appropriate for customers to pay 1 yuan for a set of "disinfection fee". The main reason why disposable tableware is difficult to exit the market is the high profit of disposable tableware. Those enterprises that only provide paid tableware have considerable profits.

National measures:

In recent years, due to the extensive use of foamed plastic tableware, the problem of "white pollution" has aroused widespread concern from all walks of life. To this end, the state has also promulgated some laws and regulations.

1On February 2, 1999, the State Economic and Trade Commission issued Order No.6, demanding that disposable foamed plastic tableware be eliminated before the end of 2000, and the State Bureau of Technical Supervision promulgated the national standard for substitute products.

On April 23rd, 20001year, the State Economic and Trade Commission issued the Notice on Immediately Stopping the Production of Disposable Foamed Plastic Tableware.

Considerable prospects:

Merchants develop new disposable tableware according to the present form.

Starch is a kind of natural polymer, and its biodegradability is incomparable to other synthetic materials, and it is also called completely biodegradable material. The starch can be corn starch, rice starch, potato starch, especially corn starch. There are many resources that can be processed and utilized all over the country, and people generally eat less starch. In addition, it can be recycled as feed when making fast food boxes, and the added fiber can be corn straw, wheat straw and so on. Therefore, the research, development and industrial production of natural starch biodegradable disposable tableware are important green industrial projects to protect the living environment of human beings. Compared with plastic tableware, this biodegradable tableware has the advantages of recyclable resources (feed and fertilizer), water solubility, photolysis and biodegradability.

Conclusion:

Disposable tableware-to increase our understanding of it, we should not only consider our short-term interests, but also look forward and see our own shortcomings and the living environment of the next generation before we realize that we are too selfish to cherish what we have. As high school students, we should do our part for all this, instead of blindly following the trend and others. Through practice, we know that disposable chopsticks are harmful to some extent. Most importantly, these disposable tableware have the nature of * * *: wasting the limited resources on the earth will do more harm than good to yourself and others. Reducing and not using them will be our greatest favor to ourselves. Saving resources is our duty, and it is also our responsibility to protect the environment.
