Why not replace wooden sticks and plastic sticks in medical swabs with paper sticks? Would using paper sticks be more environmentally friendly?

Because paper sticks are environmentally friendly and recyclable, even garbage disposal is more convenient, even if children carelessly bite it, it is not harmful, and plastic is not environmentally friendly and is not easily degraded. If children accidentally eat it, it will be harmful to health. White pollution is a one-time refractory plastic packaging. For example, disposable foam fast cutlery and our commonly used plastic bags, etc. It is very polluting to the environment, it is difficult to decompose in the soil, it will cause the soil capacity to decline, and if it is burned, it will cause atmospheric pollution, so it is now advocated not to use It is best to bring your own tools when buying things to reduce its use. 1. The status quo and harm of "white pollution" As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology, and low cost. They are widely used all over the world and are increasing year by year. The growth rate of plastic packaging materials in the world market is higher than that of other packaging materials. The average annual growth rate of plastic packaging materials from 1990 to 1995 was 8.9%. my country is one of the world's top ten producers and consumers of plastic products. In 1995, my country’s plastic output was 5.19 million tons, and Japan’s plastic output was nearly 6 million tons. The country’s total plastic consumption was about 11 million tons, including 2.11 million tons of plastic for packaging. Most of the plastics used for packaging are discarded in the environment in the form of waste films, plastic bags and foam plastic tableware. These waste plastic packaging materials are scattered on both sides of urban areas, scenic tourist areas, water bodies, and roads, which not only affect the landscape and cause "visual pollution", but also cause potential damage to the ecological environment because of their difficulty in degradation. According to the survey, 3% of the municipal solid waste in Beijing is waste plastic packaging, totaling approximately 140,000 tons per year; 7% of the domestic solid waste in Shanghai is waste plastic packaging, totaling approximately 190,000 tons per year. Tianjin's waste plastic packaging also exceeds 100,000 tons per year. Each year, about 2.3 billion plastic bags are discarded in the environment in Beijing, about 220 million plastic disposable tableware, and 6.75 million square meters of waste agricultural film. People dubbed it "the suburbs of the city". The main hazards of "white pollution" are "visual pollution" and "potential hazards": 1. "Visual pollution". Waste plastic packaging scattered around cities, tourist areas, water bodies and roads brings bad stimulation to people's vision, affects the overall beauty of cities and scenic spots, and destroys the city appearance and landscape, thus causing "visual pollution". 2. "Potential hazard". After the waste plastic packaging enters the environment, it is difficult to degrade, causing long-term and deep-level ecological and environmental problems. First, the waste plastic packaging is mixed in the soil, which affects the absorption of nutrients and moisture by the crops, which will lead to a reduction in crop production. Second, the waste plastic packaging discarded in land or water is swallowed by the animals as food, causing the animals to die (in the In zoos, pastoral areas, and oceans, this kind of situation is not uncommon); third, the waste plastic packaging mixed with domestic waste is difficult to handle: landfill treatment will occupy the land for a long time, and domestic waste mixed with plastic is not suitable for composting. The waste plastics sorted out are also difficult to recycle because they cannot guarantee the quality. At present, people strongly reflect the problem of "visual pollution", and most people still lack awareness of the long-term and deep "potential harm" of waste plastic packaging.

Why is there a small hole on the plastic stick that holds the lollipop, but there is no hole on the paper stick?

Why is there a small hole on the plastic stick that holds the lollipop, but there is no hole on the paper stick?

Remember when I was a child, the best candy was not a watermelon candy with a few dollars in the store, not a big roll of sweet and soft, not a colorful bubble gum with a bite flavor, but one by one on the boss counter Lollipop on the table. How many children can refuse the charm of lollipop? I believe that many friends born in the 1980s and 1990s will have a childhood familiarity when they see the lollipop. When I was young, I ate lollipops. What I thought about was the taste of lollipops. What apple flavor, milk flavor, cantaloupe flavor, apple flavor, grape flavor. Now when I eat lollipops, it is more about satisfying my temporary appetite. However, when you eat lollipop, have you noticed that every time you eat it, there will be a small hole in the plastic stick that holds the lollipop, filled with candy, but we can't eat sugar. So what is the use of such a small hole? It turned out that this small hole is of great significance. If there is no such hole in the plastic rod, our lollipop cannot be fixed on the plastic rod. This small hole really plays a "fixing" role. Want to know why this hole is so significant, we will start with the making of lollipop. Lollipop, raw materials are white sugar, maltose, food coloring, food flavor. When making lollipops, it is necessary to dissolve the white sugar and maltose according to a certain ratio and cook them with water to make syrup. When the white sugar and maltose are completely cooked into syrup, add the right amount of flavor and color to make the lollipop into the flavor and color you want. The boiled syrup is poured into the prepared mold. The mold can be round, square, polygonal, or any shape. After the syrup is poured into the mold, the plastic stick is about to appear. While the syrup has not set, place the plastic rod in the mold and immerse it in the syrup. At this time, the liquid syrup will wrap the plastic rod, and the small holes in the plastic rod will pour into the syrup. When the syrup cools and starts to solidify, the syrup inside and outside the holes is connected, and after solidification, it will become a unified candy. In this way, the inside and outside are fixed at the same time, so that the candy can be firmly stuck on the plastic rod and will not slide down. Without this hole, can't the lollipop be fixed? The answer is that it can be fixed, but the fixation is not strong. It is easy to lose the sugar ball during the process of eating the lollipop. Then you are likely to face two choices. Eat slowly in the mouth. The second is that the lollipop falls off the stick and falls on the floor. However, there is now a paper stick made of paper, which has no holes to fix the lollipop, and the candy will not fall off. Why? It turned out that the friction of the paper stick is much greater than the plastic stick. Use the paper stick to fix the candy. The candy will not slip off the paper stick because it is too slippery. So lollipops made of paper sticks do not need a small hole to fix the candy. Seeing this, I believe you already understand the importance of the small hole on the plastic lollipop. The little lollipop also contains a lot of human wisdom. In the future, if you want to make lollipops at home, you should also pay attention not to buy plastic sticks without small holes, or put the plastic sticks upside down. The end with small holes is to be placed in syrup to fix candy .
