In line with the goals of sustainable development, China’s "Eleventh Five-Year" plan placed greater emphasis on environmental protection. As a result, there is an increasing demand for filter materials across various sectors, including water, gas, noise, and solid waste treatment. Industry experts are optimistic about the future growth of the filter materials sector.
In particular, the use of bag-type dust collectors in soot and dust removal has gained widespread attention due to its high efficiency, lack of secondary pollution, and ability to recover dry materials. This technology is widely adopted both domestically and internationally, accounting for approximately 80% of all dust collection equipment used. According to statistics, China's filter material output reached around 40 million square meters in 2005, with 30 million square meters made from chemical fibers and 10 million from glass fibers. The total output value was 1.56 billion yuan, marking a 31% increase from the previous year. Meanwhile, the overall output value of the bag dust collection industry reached 6.5 billion yuan (including equipment), representing a 21% year-on-year growth. Despite this rapid expansion, the market demand continues to rise steadily.
In the thermal power industry, the first 200,000 kW bag filter unit was installed at Fengtai Power Plant in Inner Mongolia in November 2001. By 2005, the total filtration area had reached 1.2 million square meters, equivalent to 10 million kW units. At the end of 2005, China's total power generation capacity was 510 million kilowatts, with thermal power making up 75.6%. It is projected that by 2010, the total capacity will reach 647 million kilowatts, with thermal power at 476 million kilowatts and coal consumption expected to reach 1.4 billion tons. If 50% of these units use bag filters, a total of 36 million square meters of filter material will be needed. Assuming a three-and-a-half-year lifespan for the filters, the annual requirement would be around 10.3 million square meters.
The iron and steel industry remains one of the largest contributors to air pollution. With China’s steel production exceeding 300 million tons, the need for effective dust control is critical. Based on the dust removal system at Shanghai Baosteel, it is estimated that 21 million square meters of filter material are required. After conversion, this means replacing 6 million square meters annually. In addition, the cement industry—especially with 560 new and existing dry cement production lines—requires high-temperature fiber filter bags for dust removal. Similarly, waste incineration facilities for municipal, medical, and industrial waste also rely heavily on bag-type dust collection systems.
Given the growing demand across multiple industries, the market for bag-type dust removal equipment is expanding rapidly. Filter materials, particularly those resistant to high temperatures, are expected to play a key role in meeting this demand, offering significant long-term market potential.
