According to preliminary statistics, at present, only sanitary ceramic enterprises in Chaozhou produce more than 50,000 tons of industrial waste every year, while the accumulated ceramic waste over the years is not less than 300,000 tons. The amount of ceramic waste is so large that it occupies a lot of land. According to the masses, as long as there are gaps, ceramic waste will be glistening, some roads will be difficult to open to traffic, and some fields will be spread out in the corner by this ceramic waste, which is owned by many farmers. The industry believes that at present, the technological level of the ceramic industry in the recycling of defective products or waste products is still very low, and the cost of recycling is higher than the cost of finding raw materials again.
Judging from the current value of the enterprise, recycling is generally not considered unless the cost of raw materials is very special. I'd rather break the defective products and throw them away. For example, there are more than 300 sanitary ware enterprises in Gu Xiang town, with an annual output of more than 40 million pieces. Compared with the current daily-use ceramics and craft ceramics, sanitary ware has become the protagonist of ceramic waste because of its large volume and high yield. According to the conservative figure that the average rejection rate is 50%, Gu Xiang Town produces more than 2 million pieces of ceramic waste every year. However, some workers who ask for transportation only accept it because of greed.
A surprising amount of ceramic garbage is littered everywhere, and the masses reflect the phenomenon that this ceramic garbage pollutes the environment; The government should pay more attention and play a guiding role in the recycling of ceramic waste. At the same time, we should also increase investment in this project and strengthen management.
Faced with this situation, some enterprises believe that the government should boldly use political means, policies should be in place, and technology funds should be properly guided. In 2002, CPPCC members jointly put forward the proposal of "strengthening management to prevent the ceramic industry from affecting future generations", and the municipal government specially promulgated and implemented the Provisional Plan for Environmental Management of Ceramic Wastes in jizhou city. In order to fundamentally solve the impact of ceramic waste on the environment, since the second half of 2002, Fengxi Ceramic Research Institute of Chaozhou City, Guangdong Province has carried out the experiment of producing porcelain mud from waste porcelain, and then making porcelain mud into products. The utilization rate of waste porcelain has reached 3.5%. At present, this scientific research achievement has passed the national patent preliminary examination. On this basis, Fengxi Ceramic Research Institute actively cooperated with Guangdong Stone Group Co., Ltd. and Guangzhou Gaoqiang Machinery Equipment Co., Ltd. to establish Chaozhou Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd., and invested 75 million yuan to build the "ceramic waste recycling" project. The project is divided into three stages. The first phase officially started in early August 2003. It is estimated that after completion, the annual output of porcelain clay will be 80,000 tons, and the annual recovery of waste mud will be 280,000 tons. In the second stage, the waste mud will be further used to produce daily-use ceramics.
The third phase project will enter the stage of sanitary ware production. Chen Shimin, the project leader and director of Fengxi Ceramic Research Institute, told the reporter that the porcelain clay produced by recycling waste porcelain is superior to ordinary porcelain clay in terms of thermal stability, temperature and hardness. However, the most attractive thing about this project is its inestimable social benefits. Chen Shimin said happily that after the completion of Xiangri, nearly half of Chaozhou's ceramic waste can be effectively treated every year, and the waste can be reduced and treated harmlessly, which has contributed to the sustainable development of Chaozhou's ceramic industry. Through a small survey, we know that most of the ceramic wastes in Fengxi are purchased by some companies, and a large amount of waste is about 100 yuan to 200 yuan. These purchasing companies reuse waste to achieve sustainable use.
The following are some measures to utilize ceramic waste:
(1) is used to make bricks. For example, the hard diamond unique to the decoration market, the green building material product in Yan Ruyu-metal tiles. It is not allowed to produce metal tile such as red porcelain, white porcelain and grey porcelain.
(2) Used for ceramic tile blank. After recovery, impurity removal and iron removal, the waste mud water can be added to ceramic tile for ceramic tile blank.
(3) It is used to produce porous ceramics.
(4) used for preparing cement. Ceramic waste has good grindability. After rough treatment of ceramic waste, a small amount of surfactant solution is added for washing. Ordinary portland cement with higher strength grade can be produced by using waste ingredients.
(5) It is used to develop concrete materials. Solid waste concrete material is a kind of environmental protection material with ordinary concrete properties, which is mainly solid waste. Used to make building wall materials and road pavement materials.
With the comprehensive utilization of Chaozhou green ring ceramic resources, enterprises and the government began to deal with the problem of ceramic waste, Chaozhou's environment has been alleviated. Chaozhou has become beautiful in recent years, but we will continue to promote energy conservation and consumption reduction activities. Otherwise, garbage not only takes up space, but also affects the urban landscape. Chen Shuihong, chief of the comprehensive department of the Municipal Environmental Protection Bureau, said: The dumping of ceramic wastes not only pollutes the environment, blocks rivers, encroaches on cultivated land, causes waterlogging in related areas, hinders urban production, and has a great impact on the ceramic image of China. Moreover, these ceramic wastes are refractory substances, which have a far-reaching impact on the entire ecological environment.
Therefore, strengthening the recycling of resources is a process that can promote sustainable development and reduce resource consumption. Less environmental pollution, low production cost and good economic benefits will play a great role.
It is an important task to carry out the spirit of the 16th National Congress of the Communist Party of China, take the road of new industrialization and build a well-off society in an all-round way. Therefore, we should take various measures to increase the recycling of resources, better implement the Party's policies, and try our best to save energy and raw materials. In this way, our future generations can continue to develop, which is what all of us hope to see.
Ceramic garbage is actually a kind of resource, which can be completely recycled. Simply burying waste porcelain not only causes environmental pressure, but also is a serious waste of resources. From the point of view of environmental protection and resource conservation, to solve the problem of ceramic waste, we must take two measures, increase capital and technical input, improve the yield of ceramic products, vigorously promote the recycling technology of waste porcelain, and fundamentally reduce or even completely eliminate ceramic waste. The most important thing is to completely change the situation of' enterprise pollution, the government pays the bill'.
In the long run, to completely solve the problem of ceramic waste, we must vigorously promote the recycling technology of waste porcelain, support and establish large-scale recycling enterprises of waste porcelain in major ceramic producing areas, and meet the recycling demand of waste porcelain in all producing areas. At the same time, it is necessary to study and formulate scientific and effective policies and measures, collect waste porcelain recycling fees from ceramic enterprises fairly and reasonably, support the development of waste porcelain recycling industry, and truly save resources and protect the environment.
Chaozhou "Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd." has come up with a magical way to regenerate waste porcelain. They smashed waste porcelain and waste residue into powder particles, and carried out experiments for a whole year with 10 different formulations according to the different proportions of the two materials. Many things happen. They worked hard to solve the problem, finally unveiled the mystery for the first time, obtained scientific data, and worked out a successful plan to magically regenerate waste porcelain.
In view of the increasing ceramic waste, the environmental pressure is increasing. The "Demonstration Project of Ceramic Waste Recycling" implemented by Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd. can recover 30,000 tons of waste porcelain and produce 60,000 tons of recycled porcelain clay annually, which basically solves the problem of recycling ceramic waste in our city.
According to the person in charge of Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd., the waste porcelain is processed and regenerated into porcelain mud. The first advantage is that molding shrinkage is relatively low. The strength of firing is good in all aspects, and raw materials can be saved on the original basis.
A number of other enterprises in our city have also made new breakthroughs in raw material innovation, equipment transformation, energy saving and consumption reduction. Representatives of these ceramic enterprises said that they should learn from the advanced experience of the same industry, learn from each other's strong points, continue to strengthen research and development in kiln renovation, waste residue recovery, energy saving of raw materials, etc., and promote the rapid and healthy development of Chaozhou ceramic industry.
It is reported that the porcelain clay produced from recycled waste porcelain is superior to ordinary porcelain clay in thermal stability, temperature and hardness. After the completion of the project, half of the ceramic waste can be effectively treated every year, and the waste is reduced, recycled and harmless, which is conducive to the sustainable development of Chaozhou ceramic industry.
Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd. makes waste porcelain magically regenerate. Not only has a new circular economy model of ceramic production been established, but also ceramic waste has been reduced, recycled and harmless, which has triggered an "earthquake" in the ceramic industry. Many enterprises in Chaozhou went to learn from the scriptures and made a big article on the recycling of ceramic waste residue. According to the estimation of relevant departments, the waste porcelain in Chaozhou reaches more than 654.38+10,000 tons a year, and the green ring can digest 28,000 tons.
To sum up, we should encourage and support powerful enterprises, take the lead in setting an example, actively develop the recycling technology of ceramic waste, and use science and technology to turn ceramic waste into treasure. Reduce the production and discharge of ceramic waste in all aspects of ceramic production.
In the long run, the production of ceramic waste should be reduced from all aspects of production. After the waste porcelain is crushed and mixed with porcelain clay, the recovery rate can reach 100% and the production cost can be reduced by 3%. However, there are still many problems unsolved, such as the lack of concentration of ceramic waste, the difficulty in collection, the increase in cost and the immature recycling technology. Most small and medium-sized ceramic enterprises are unwilling to spend energy on these ceramic wastes, and there are various restrictions.
