Stone paper is an environmentally friendly product using calcium carbonate, the most abundant mineral resource in the earth's crust, as its main raw material. It is an alternative to traditional paper. It is biodegradable, capable of writing, and is water and oil resistant. The application field is very wide, and it can be used in garbage bags, shopping bags, food bags, etc.; it can also be used in cultural paper, such as printing paper, writing paper, etc.; it can also be used in building materials decoration, industrial packaging and other fields, and even Applied to special paper, such as field work paper, military special paper, etc.
stone paper comes from mines, does not need to cut vegetation, and is a great protection for forests. In the traditional papermaking process, a large number of trees are required to be felled and a large amount of water is used, resulting in "three wastes" that pollute the environment, which is a high-emission, high-pollution, and high-energy-consuming industry. The production process of low-carbon environmentally friendly stone paper does not require water, consumes forest resources, does not produce exhaust gas or waste residue, and the product is degradable. The unit energy consumption is only 2/3 of the traditional papermaking process. It is a pollution-free green environmental protection project. With an annual output of 120,000 tons of environmentally friendly paper, it can save 24 million cubic meters of fresh water resources and 2.4 million wood, which is equivalent to 324,000 mu of tree planting.
At present, in addition to the relatively mature technologies in the United States, Japan, and Taiwan, there are also several domestic companies that have technologies and patents in this area, such as the EarthGuard Company and Chengdu XinKeli. According to Mr. Jiang, the marketing manager of Chengdu Xinkeli Chemical Technology Co., Ltd., in the 1980s, some Chinese enterprises began to develop "stone paper" and its production equipment. Technically speaking, the production of "stone paper" has the conditions for large-scale production.
The author believes that the development of stone paper is a trend. The reasons are as follows. First, my country is rich in mineral resources and raw material resources. Secondly, the stone paper production process has minimal damage to the environment, conforms to the low-carbon and environmentally friendly green development concept, is supported by people, and is expected to be assisted by the government. Furthermore, the production cost is low. The stone-paper production process does not require trees, water, and no waste gas or water. This reduces the cost to a certain extent. This is the most attractive for paper manufacturers. It is reported. , The cost of stone paper products is 20%-30% lower than alternative products; and there is no need to bear the environmental governance costs incurred by traditional papermaking, including the carbon trading costs that are currently of concern. Finally, the production technology and equipment of stone paper have been relatively complete, and the time is ripe.
However, in the early days when stone paper was first introduced, the technology and equipment were limited, and the quality was not satisfactory. The voices of support and opposition were divided. When stone paper was first launched, compared with ordinary paper, users reported that the surface of stone paper was rough, the ink for writing was easy to faint, it was difficult to write, and burning would give off a pungent smell similar to burning plastic. The quality defects in the initial stage of stone paper production set up numerous obstacles to its development.
Stone paper, a new type of environmental protection industry, has a tortuous and smooth development path. The first thorough revolution in papermaking raw materials in history undoubtedly raised my country’s papermaking industry to a higher level. It can break away from the shackles of plant fibers and produce products that satisfy people. Alternative products on demand. With the continuous improvement of stone paper production technology in China, stone paper is slowly being accepted by consumers, and the stone paper market is gradually showing a boom. Let's take a look at the large-scale stone paper production projects in China.
