Article of this newspaper: How to achieve high-quality development of the brick and tile industry?

As an important part of traditional Chinese building materials, bricks and tiles carry rich historical and cultural connotations. China is one of the earliest countries in the world to produce sintered bricks and tiles, and has a history of more than 7,000 years. In the past, bricks were mainly made from clay, with a low entry threshold and many enterprises, most of which were mainly small-scale enterprises. This leads to the low production concentration rate, low efficiency, single product of the brick and tile building materials industry, serious unorganized emissions, difficult dust control and other problems, and at the same time, to a certain extent, it has also caused the destruction and waste of regional ecological environment and land resources. In addition, the development and innovation momentum of the brick and tile building materials industry is insufficient, and it is difficult to adapt to the needs of product function improvement and building parts.

With the development of the times, the people's yearning for a better ecological environment, and the formation of a stricter ecological environment system, the transformation of the brick and tile building materials industry is imminent. At present, it is necessary to face up to its existing problems, take practical measures to promote the high-end, intelligent and green development of the brick and tile building materials industry, and let the traditional industries glow with new vitality.

Promote clean production of bricks, tiles and building materials industry to reduce pollution and carbon emissions. Pollution reduction, carbon reduction, and clean production is an effective means for the brick and tile building materials industry to prevent and reduce environmental pollution and achieve high-quality development. We should pay attention to the following aspects: First, energy conservation and carbon reduction. Brick and tile enterprises choose high calorific value and low sulfur raw materials/fuels, such as biomass fuel, hydrogen energy and other alternative energy sources, abandon inferior coal and other polluting energy, and effectively reduce energy consumption and carbon dioxide emissions. The second is upgrading. Enterprises can reduce the production of solid bricks to the production of porous hollow bricks, and at the same time upgrade the production process, which can not only reduce the consumption of raw materials, but also further reduce energy consumption. The third is to strengthen management and control. All localities can fully rely on the opportunity of issuing pollutant discharge permits to strictly control the installation and use of terminal treatment facilities, and actively guide enterprises to install terminal treatment facilities with high removal rate and stable operation. At the same time, enterprises are urged to install online monitoring facilities to effectively monitor the pollution emissions of brick and tile enterprises through the online monitoring system.

Promote the brick and building materials industry to achieve comprehensive utilization of solid waste. The comprehensive utilization of solid waste is the only way to reduce the consumption of natural resources and achieve sustainable development. On the one hand, local governments should formulate policies to support the use of construction waste to produce brick and tile products, expand the scope of comprehensive utilization of resources, improve comprehensive disposal capacity and utilization efficiency, and encourage brick and tile enterprises to use industrial solid waste, tailings sand, sludge, sludge, agricultural and forestry wastes and other alternative disposable raw materials. On the other hand, enterprises should reduce the consumption of natural resources by increasing the proportion of solid waste blending in raw materials. At the same time, strengthen investment in scientific research, research and development of the use of brick and tile sintering kilns to co-dispose of river and lake sludge, construction residue and other waste, for the government to solve the worries, reduce the burden on the environment, and achieve a win-win situation for all parties.

Promote the integration of intelligent manufacturing and production capacity cooperation in the brick and tile building materials industry. The integration of intelligent manufacturing and production capacity cooperation is an effective measure for the traditional brick and tile industry to adapt to the needs of modern industries. The traditional brick and tile firing process is not only time-consuming, labor-intensive, but also energy-consuming, which cannot meet the needs of refinement, precision and refinement of modern industries, and cannot achieve "batch copying", and the output and production capacity cannot keep up. Integrating digital, automated and intelligent production methods into the traditional industry of bricks and tiles, and using new technologies such as intelligent robots and 3D printing can not only achieve high production capacity of bricks and tiles, but also reduce the waste of materials and energy, and realize efficient and accurate production of bricks and tiles. At the same time, it can also carry out "private customization" according to market demand, and achieve cross-border integration and development with other fields to form industrial complementarity. For example, a brick and tile enterprise in Zibo can produce 50,000 standard bricks in one hour by using modern intelligent equipment, with a compound annual growth rate of more than 20% in revenue and profit.

It is imperative to promote the transformation and development of the brick and tile building materials industry. All localities should grasp the fundamentals of pollution control, increase law enforcement, raise the entry threshold, and eliminate inferior and high-pollution production capacity. Enterprises should seize the opportunity of industrial transformation and upgrading, make efforts in pollution reduction and carbon reduction, solid waste utilization, and intelligent manufacturing integration, promote the green, low-carbon and high-quality development of the brick and tile building materials industry, and make positive contributions to the realization of the goal of carbon peak and carbon neutrality.
