Environmental protection building materials still need to work hard

Rapid Development of Pollution in China's Building Materials Industry The serious building materials industry is an important material industry in China. Building materials products include construction materials and products, non-metallic minerals and products, and inorganic non-metallic new materials. They are widely used in fields such as construction, military industry, environmental protection, high-tech industries, and people's lives.

At present, China is already the world’s largest producer and consumer of building materials. The main building materials such as cement, flat glass, building sanitary ceramics, stone and wall materials have been ranked first in the world for many years.

However, the pollution caused by building materials caused by the environmental building materials industry is also very serious, especially the pollution of decorative materials is the most obvious. In August 2009, the State Administration of Quality Supervision, Inspection and Quarantine announced the results of law enforcement inspections conducted recently on eight types of interior decoration products such as wood furniture, wood-based panels, interior wall paints, and fireproof panels. The results showed that formaldehyde and other harmful substances were found in interior decoration and decoration products. The issue of excessive emissions remains prominent. And these products are selling at major building materials stores. In fact, since the advent of the decoration industry, pollution of decorative materials has always been an inevitable problem. The state has taken various measures to crack down on unscrupulous businesses and has used a large amount of pollution materials to reduce costs, which has certain results. The birth of new materials also promoted the environmental protection of building materials.

In construction materials, products with poor quality have reduced the lifespan of construction projects and caused unnecessary waste. In particular, stone products are particularly polluted. At the beginning of 2010, the "stained marble" incident that occurred sounded the alarm for construction projects. A stone factory owner in Changchun blasted the inside story, saying that the colors of these two kinds of stone were mostly artificially dyed, which was very serious for environmental pollution and human injuries. According to the boss, the pigments used for marble staining were poisonous. The manufacturers who processed this dyeing process were all in other provinces. The relevant local departments have forbidden the production of dyed marble. However, under the drive of interests, the stone merchants are still operating in a dark box. , to other provinces processing toxic dyed marble. Such incidents have seriously affected the order of the building materials market. The relevant departments have conducted vigorous investigations and punishments.

In addition, on June 26, 2010, the U.S. House of Representatives passed the "U.S. Clean Energy Security Act" to formally incorporate the "carbon tariff" into the world's vision in response to the name of climate change. According to U.S. regulations, from 2020 onwards, trade sanctions will be imposed on countries that do not accept pollutant emission reduction standards. The specific measures will be to impose punitive tariffs on foreign products that do not meet the carbon emission standards. It is understood that similar situations have begun to emerge in developed countries such as Europe.

The industrial products exported by China are mostly resource-input products, which have high energy consumption and low added value. The price advantage is welcomed in the low-end and international markets. If "carbon tariffs" take shape, industrial export products produced in existing models will be fatally hit. The just-concluded Central Economic Work Conference also pointed out the end of high-energy-consuming products: the government will improve export quality and added value, and strictly control the export of resource-based products, high-pollution and high-energy-consuming products.

Be all-sided, energy-efficient and energy-efficient Chinese industrial products can only go this way. Many practitioners of industrial enterprises stated that this time, China’s aggressive use of high energy consumption is a real thing.

It can be seen that the impact of the building materials industry on the environment is very serious, and the building materials industry is developing rapidly. It is necessary to achieve healthy development and reduce pressure on the earth. Energy conservation and environmental protection are imperative.

Energy conservation and environmental protection The building materials industry is a large energy consumer in the mobile building materials industry, but it has a large space for energy conservation. The three major reasons for the high energy consumption of the building materials industry are the irrational structure, high energy consumption per unit, and rapid growth in total volume. The high energy consumption of the building materials industry is mainly due to the irrational industrial structure, the high energy consumption of the product units, and the excessive growth of the total volume. Therefore, energy conservation and consumption reduction can be carried out from several aspects such as adjusting the industrial structure, reducing the unit energy consumption, and controlling the total growth. The specific measures include increasing the proportion of new dry process cement, the ratio of float glass and high quality float glass, and improving the deep processing of glass. Rate, construction of low-temperature waste heat power generation projects, development of recycling economy, and structural adjustment is the most important way to reduce the overall energy consumption of the industry.

For the development of the global green environmental protection business, the earth is also clean, and energy saving and environmental protection of building materials is imperative. In 2007, the state and industry-related departments have launched more than 10 environmental protection policies for the building materials industry. We believe that energy conservation and emission reduction is very beneficial to the future development of the building materials industry. Its positive impact is mainly reflected in the following aspects: First, it can speed up the withdrawal of backward production capacity, reduce the higher energy consumption of the newer dry process produced by the backward production process, and secondly, promote the adjustment of the industrial structure and improve the relationship between supply and demand. Third, to promote industry mergers and acquisitions and reorganization, and then to increase industry concentration, and to promote industry competition model from low-cost disorderly competition to enhance competition in regional control; Fourth, through the construction of waste heat power generation, recycling economy and other projects to reduce the industry At the same time, its own cost will produce better social benefits.

On November 26, 2009, the Chinese government issued a carbon emission reduction voice to the world: By 2020, the GDP of a unit of GDP will fall by 40% to 45% compared with 2005. A few days later, the domestic high-energy-consuming industries received detailed indicators for elimination of outdated production capacity by the Ministry of Industry and Information Technology. Among them, iron and steel, steel, cement and glass industries need to eliminate backward production capacity of 21.13 million tons, 16.91 million tons, 74.16 million, respectively. Tons and 6 million weight boxes, totaling more than 100 million tons. According to Xiong Bilin, inspector of the Industry Coordination Department of the National Development and Reform Commission, in order to achieve China's 2020 carbon emission reduction targets, the above-mentioned industry's task of eliminating backward production capacity is very arduous.

Today, the quality of building materials continues to increase, energy and raw material consumption are declining year by year, new types of building materials continue to emerge, and building materials products are continuously upgraded. It also played a role in promoting the development of energy-saving and environmental-friendly building materials.

Fast development of energy-saving building materials products is not easy to promote energy-saving building materials is a material used to reduce energy consumption of buildings, including: installation of hollow coated glass steel energy-saving windows, can prevent UV, isolate outdoor noise, maintain indoor heat in winter; Wall insulation system materials are used to reduce energy consumption in buildings and eliminate the heat island effect. Indoor wall tiles are covered with environmental protection materials to prevent pollution and reduce indoor cooling and heating energy loss. Buildings using these materials can achieve the effect of “cool in winter and cool in summer”, which is both energy-saving and comfortable. With such a shortage of energy resources, the promotion of energy-saving building materials should be of great practical significance.

In 2008, the construction of Olympic venues embodies the concept of green Olympics. During the construction process, under the premise of ensuring the quality of the project, extensive use of new energy-saving and environmental protection materials, such as: the application of the ecological sand-based permeable bricks in the Fengtai Softball Field and the Olympic Traffic Command Center, has met the needs of the project and opened up international Precedent; energy-saving board has been applied to 42 apartments in the Athlete Village, a total of about 550,000 square meters, after the test has fully achieved the expected environmental protection and energy conservation requirements; new waterproof technology into the T3 terminal project, the quality of all the key projects The design requirements have been well received by all parties; new technologies and new products for ready-mixed mortar have entered the "Bird's Nest" stadium at the Olympics and have also received unanimous praise. The concept of the Green Olympics in the construction of the Olympic Games Stadium undoubtedly created a precedent for the Shanghai World Expo and the Guangzhou Asian Games. More and better new materials for energy conservation and environmental protection will be more widely used in Shanghai and Guangzhou.

Although the 2009 Copenhagen conference was held without reaching any legally binding agreement, it used the term low-carbon in every corner of the world. The low-carbon road to building materials has also become the most sought after development in the industry. However, the recent appearance of the sound of “energy-saving building materials are not well-known” has forced companies to stop development and ponder the future of energy conservation and environmental protection.

It is understood that after energy saving and environmental protection building materials are put into the market, the sales volume cannot be as loud as the name suggests. Consumers tend to have low enthusiasm for such products. Liu Haibo, general manager and senior engineer of the Construction Engineering Inspection and Certification Division of China Building Materials Inspection and Certification Center stated that in recent years, China has actively promoted the research, development, and application of new energy-saving building materials, but developers and ordinary consumers have low awareness of energy conservation. Real estate developers are reluctant to increase investment to improve the energy efficiency of buildings, and consumers have limited knowledge of the cost of living caused by the use of energy-saving building materials. In addition, the prices of some retail energy-saving building materials in the market are higher than those of ordinary building materials, thus resulting in low enthusiasm for the use of energy-saving building materials.

The promotion of energy-saving and environmental-friendly building materials requires joint efforts to promote the implementation of energy-saving and environmentally-friendly building materials, and requires multiple efforts. First, it is important to increase consumer awareness of environmental protection. Consumers are the main driving force in the transition process of low-carbon economy and are an important part of guiding the development of industries and society toward a low-carbon economy. How to guide consumers' environmental awareness has become a key task for companies and even countries.

Secondly, it will promote the integration of consumption and energy conservation and environmental protection policies: With energy conservation and environmental protection as the main entry point, a scientific and technological innovation system will be established with the principle of “country-oriented, enterprise-oriented, market-oriented, and production-study-research-combination”. Resource-saving and environment-friendly production, circulation and consumption methods.

Finally, through national policy subsidies to boost development: the development and application of all technologies will undergo a transition process from high cost to low cost. If the country introduces a corresponding subsidy policy, it will accelerate the process of reducing costs. Subsidizing some energy and technologies that are temporarily out of commercial competitiveness and have relatively low social costs will enable them to grow more quickly and move toward market competition.

The road to energy conservation and environmental protection in the building materials industry is still very long. With the gradual enhancement of consumer environmental awareness, energy-saving and environmental-friendly building materials will surely occupy a large proportion in the future market. Of course, in order to better nurture and develop consumer hotspots, the government needs to make improvements in improving the system, raising residents’ income expectations, narrowing income gaps, opening up rural consumer markets, and creating a good consumer environment.
