The Urgent Urgency of the Ceramic Industry: Turning Waste into Treasure

In the early processing of ceramic waste, ceramic waste was considered as a “burden” by the enterprise due to the absence of related recycling technology. It was solved like a “garbage” through a simple landfill method, or was used to fill a trench, roadbed, etc. Even more directly fell to the roadside, farmland, rivers and other places. Because ceramic waste cannot be degraded, the waste contains chemical substances that seriously pollute the water, air and soil environment on which people depend.

In the ceramics factory area, the annual output of various ceramic wastes has exceeded 4 million tons, and the annual national ceramic waste production is estimated to be around 10 million tons. How to turn these wastes into treasures becomes a top priority for the entire industry to achieve sustainable development. .

In recent years, many ceramic companies have strengthened research projects such as the recycling of non-renewable resources, and have achieved encouraging results by reducing the generation of pollutants from the source. A variety of waste bricks have been crushed into large quantities for use as raw materials, and sludge slags of various types of ceramic bricks have also begun to be applied to the green body formulations.

In addition to the use of ceramic waste as a building ceramic raw material, ceramic waste can also be used in the production of daily-use ceramics and sanitary ceramics, the production of industrial ceramics, the production of ceramics and sound-absorbing materials, the production of cementitious materials, and the research and development of companies and experts. Its products, used for the recovery of heavy metals, cement production and other products.

The use of ceramic waste for the application of ceramic products has great economic benefits. On the one hand, the amount of ceramic waste residue accounts for 16%-22% of the formulation, and the annual amount of waste residue is more than 60,000 tons, which can save raw material costs and waste residue disposal fee of 8 million yuan. Above, on the other hand, because the fineness of the waste slag is small, the milling time can be shortened by 2 hours on the original basis. Therefore, the annual electricity bill can save about 2 million yuan, and the economic benefit is very considerable. While achieving great economic benefits, ceramic waste and waste recycling projects have also made significant contributions to the government's ongoing energy conservation and emission reduction projects.

In response to the recycling of ceramic waste, Professor Zeng Weike of South China University of Technology stated that the technology for the recycling of ceramic waste is now very mature, and that many companies have successfully used ceramic waste to develop new green building materials that demonstrate the recycling of ceramic waste. It is feasible to use this road, and we should stick to it and maximize the use of resources.

In the path of resource conservation, in addition to recycling ceramic waste, the use of low-grade ceramic raw materials for production is also an important means of saving resources. For the ceramics industry, saving resources is to save raw materials, and the green body accounts for 95% of the total ceramic tile materials. Therefore, in recent years, many industry experts have proposed thinning tiles and using low-grade raw materials for production.

Although domestic consumers have the view that the quality of tile blanks is better, the reality is that in the world's most powerful ceramic countries, Spain and Italy, most ceramic companies use local red earth resources to produce glazed tiles. Nowadays, the world-famous red-brick ceramics brands are basically owned by companies in Spain and Italy. In South America, Brazil, Mexico, Asia, Thailand, etc., many of their glazed ceramic tiles are also made from red raw materials. Foreign consumers do not use the color of the blank as the basis for judging the quality of ceramic products. It can be seen that China's ceramic industry will have a broad space for development by using low-grade raw materials for production.
