According to preliminary statistics, at present, only sanitary ceramic enterprises in Chaozhou produce more than 5, tons of industrial waste every year, while the accumulated ceramic waste over the years is not less than 3, 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, there are glistening figures of ceramic waste in front of factories, behind houses, in fields and along roads, some roads are piled up and it is difficult to open to traffic, and some fields have been spread by this ceramic waste. According to the insiders, at present, the technological level of recycling defective products or waste products in the ceramic industry is still very low, and the cost of recycling is higher than the cost of finding raw materials again. Therefore, from the current value of enterprises, recycling is generally not considered unless the cost of raw materials is very special. I would rather break the defective products and throw them away. For example, there are more than 3 sanitary ware enterprises in Gu Xiang town, with an annual output of more than 4 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 size and high rate of used products. According to the conservative figure that the average rejection rate is 5%, Gu Xiang Town produces more than 2 million pieces of ceramic waste every year. However, some transport workers just dump the < P > amount of ceramic waste in order to be greedy, and the masses reflect the phenomenon that this kind of ceramic waste pollutes the environment. The government should pay more attention to it and play a guiding role in the recycling of ceramic waste. At the same time, it 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, and policies should be put in place to properly guide technical funds. In 22, 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 interim plan for environmental management of ceramic waste in Jizhou City. In order to fundamentally solve the environmental impact of ceramic waste, since the second half of 22, 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, and its utilization rate of waste porcelain has reached 3.5 irrigation. At present, this scientific research achievement has passed the national patent preliminary examination. On this basis, Fengxi Ceramics Research has actively joined Guangdong Sitong 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 phases. The first phase was officially started in early August 23. It is estimated that after completion, the annual output of porcelain clay will be 8, tons, and the annual recycled waste mud will be 28, tons. The second phase will further utilize the waste mud to produce daily-use ceramics, and the third phase will enter the production stage of sanitary ware. Chen Shimin, director of Fengxi Ceramic Research Institute, the person in charge of the project, told the reporter that the porcelain clay produced by recycling waste porcelain is better than 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 products can be effectively treated every year, and the waste can be reduced and treated harmlessly, which will make use of 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 load of waste is about 1 yuan to 2 yuan. These purchasing companies reuse the waste and achieve sustainable utilization.
The following are some measures for the utilization of ceramic waste:
(1) It is used to produce bricks. Such as the unique hard diamond in the decoration market, and the green building materials products in Yan Ruyu-metal tiles. It is not allowed to produce metal tiles such as red porcelain, white porcelain and gray porcelain.
(2) Used for ceramic tile blank. After recycling, removing impurities and removing iron, the waste muddy water can be added into ceramic tiles 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 waste proportioning.
(5) It is used to develop concrete materials. Solid waste concrete material is an environmental protection material with ordinary concrete properties, which is mainly based on solid waste. It is used to make building wall materials and pavement materials for roads.
Chaozhou Green Ring Ceramic Resources Comprehensive Utilization Company, business people and the government started to deal with the problem of ceramic waste, which eased the environment in Chaozhou. In recent years, Chaozhou has become beautiful, but we have to continue to promote the activities of energy conservation and consumption reduction. Otherwise, waste not only takes up space, but also affects the city landscape. Chen Shuihong, chief of the comprehensive department of the Municipal Environmental Protection Bureau, said: The littering of ceramic wastes not only pollutes the environment, blocks rivers, encroaches on cultivated land, causes waterlogging in the relevant areas, hinders the production of the city, and has a great impact on the image of China ceramics. Moreover, these ceramic wastes are refractory substances and have a far-reaching impact on the entire ecological environment.
therefore, strengthening the recycling of resources is a process that can promote sustainable development, with low consumption of resources. Less environmental pollution, low production cost and good economic benefits will play a great role.
It is an important task to implement 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, various measures should be taken to increase the recycling of resources, better implement the Party's policies and try to save energy and raw materials. In this way, our future generations can continue to develop, which is what all of us want to see.
Ceramic garbage is actually a kind of resource, which can be completely recycled. Simply burying the waste porcelain will not only cause environmental pressure, but also be a serious waste of resources. From the perspective of environmental protection and resource conservation, to solve the problem of ceramic waste, we must take a two-pronged approach, increase capital and technical input, improve the finished product rate of ceramic products, and vigorously promote the recycling technology of waste porcelain to fundamentally reduce or even completely eliminate ceramic waste. "The most important thing is to completely change the situation of' corporate 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 waste porcelain recycling enterprises in major ceramic producing areas, and meet the needs of waste porcelain recycling in the whole producing areas. At the same time, it is necessary to study and formulate scientific and effective policies and measures to collect waste porcelain recycling fees from ceramic enterprises fairly and reasonably, so as to 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 worked out a solution to magically regenerate the waste porcelain. They crushed the waste porcelain and waste residue into powder particles, and experimented with 1 different formulations for a whole year according to different proportions of the ridged and viscous materials. Everything comes to him who waits. They worked hard to solve the problem, and 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 fact that ceramic waste is increasing day by day and the environmental pressure is increasing. The "Demonstration Project of Ceramic Waste Recycling" implemented by the Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd. can recycle 3, tons of waste porcelain and produce 6, tons of recycled porcelain clay annually, which basically solves the problems of recycling and utilization of ceramic waste in our city.
According to the person in charge of Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd., the waste porcelain is made into porcelain clay through processing and recycling after processing. The first advantage is that the shrinkage rate of molding is relatively low. It has good strength in all aspects of firing, and can also save raw materials on the original basis.
other enterprises in our city have also made new breakthroughs in raw material innovation, equipment transformation and energy saving. 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, and continue to strengthen research and development in kiln renovation, waste residue recovery, energy saving of raw materials, so as to promote the rapid and healthy development of Chaozhou ceramic industry.
It is reported that porcelain clay produced from recycled waste porcelain is better than 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 can be reduced, recycled and harmless, which is conducive to the sustainable development of Chaozhou ceramic industry.
Green Ring Ceramic Resources Comprehensive Utilization Co., Ltd. can magically regenerate the waste porcelain. Not only has a new circular economy model of ceramic production been constructed, 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 great article on the recycling of ceramic waste residue. According to the estimation of relevant departments, Chaozhou wastes more than 1, tons of porcelain a year, and the green ring can digest 28, tons
To sum up, it is necessary to encourage and support powerful enterprises, take the lead, actively develop recycling technology of ceramic waste, and turn ceramic waste into treasure with science and technology. Reduce the production of ceramic waste in all aspects of ceramic production and reduce the discharge of ceramic waste.
In the long run, the production of ceramic waste should be reduced from all aspects of production, and the waste porcelain produced can be treated and crushed, and the recovery rate can reach 1%, and the production cost can be reduced by 3%. However, there are many unsolved problems at present, 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.
