The earth is the home on which every one of us lives, and this home is being polluted by various kinds of household garbage. Domestic garbage is a by-product of human activities. With the rapid development of social economy, the amount of domestic garbage is increasing gradually, among which "white pollution" - plastic is the most serious. Because waste plastics will not degrade under natural conditions, if burned directly, harmful gases will be released, which will cause huge pollution to the natural ecological environment.
Fortunately, with the development of technology, the recycling and recycling technology of garbage in daily life has gradually developed and matured. Golden Ocean Plastics will give you a brief analysis of the existing new plastics - biological plastics. The so-called bioplastics refers to the extraction of a large number of starches and proteins from pure plants, the formation of acrylic acid and polylactic acid through the role of microorganisms, the extraction of acrylic acid and polylactic acid in plants, and then through various complex processes to produce biodegradable plastics.
Bioplastics do not depend on petroleum products, have the advantages of self-decomposition, accelerating the development of plastic recycling industry, which is slowly progressing, so it is renewable, degradable and non-polluting, so it is very in line with today's environmental protection theme. Nowadays, it has gradually replaced the traditional plastic into our life. In life, bioplastics can be found everywhere, such as TV frames, computer frames, kitchen garbage bags, beverage bags, mobile phone accessories and so on.
Although bioplastics have great potential for development, there are still many problems to be solved.
First, the cost of bioplastics is huge in the initial stage and high in the later stage, which is two to three times higher than that of ordinary plastics. This greatly reduces the enthusiasm of enterprises for bioplastics and makes it impossible for the rapid popularization of bioplastics.
Second, a large number of plants are used in the production of bioplastics, but also edible plants such as corn and wheat, which may aggravate the problem of food shortage and drive up world food prices. Now the world has begun to try to use food-intensive crops to produce bioplastics.
Third, the lack of government to promote the development of the industry, the lack of unity of the bio-plastic industry itself, resulting in consumers'understanding of bio-plastic and even distrust.
Fourth, doubts about the safety of genetically modified materials. The raw materials used in bio plastics are basically corn, sugar cane, sweet potato, wheat and so on. In order to reduce costs, manufacturers often are genetically modified foods, and genetically modified foods have not been accepted by the masses, so the planting area has not been much.
