In line with the goals of sustainable development, China's "Eleventh Five-Year" Plan has 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 market.
One of the most promising areas is the use of bag-type dust collection systems in soot and dust removal. These systems offer high efficiency, no secondary pollution, and allow for the recovery of dry materials. They are widely used both domestically and internationally, accounting for approximately 80% of dust removal equipment. In 2005, China's filter material output reached around 40 million square meters, with chemical fiber filters making up 30 million square meters and glass fiber filters 10 million square meters. The total output value reached 1.56 billion yuan, marking a 31% increase from the previous year. Meanwhile, the entire bag dust collection industry generated a total output value of 6.5 billion yuan (including equipment), showing a 21% year-on-year growth. Despite this rapid expansion, the demand for these products continues to rise.
In the thermal power sector, the adoption of bag filters has been gaining momentum. Since November 2001, the first 200,000 kW bag filter unit was installed at the Fengtai Power Plant in Inner Mongolia. By 2005, the total filtration area had reached 1.2 million square meters, equivalent to 10 million kW of capacity. With the country's total power generation capacity reaching 510 million kilowatts by the end of 2005—of which 75.6% came from thermal power—it is estimated that by 2010, the total capacity will reach 647 million kilowatts, with thermal power at 476 million kilowatts. Coal consumption is expected to reach 1.4 billion tons. If 50% of this is treated using bag filters, it would require 36 million square meters of filter material. At a 3.5-year lifespan, this translates to an annual requirement of 10.3 million square meters.
The iron and steel industry is another major contributor to air pollution. With China's steel output exceeding 300 million tons, the need for efficient dust control is critical. For example, Shanghai Baosteel requires 21 million square meters of filter material for its bag-type dust removal system. This means an annual replacement of 6 million square meters. Additionally, China's 560 new and existing cement production lines also rely on high-temperature fiber filter bags for dust control. Other sectors, such as waste incineration in municipal, medical, and industrial settings, also depend heavily on bag-type dust removal systems.
Given the growing demand across multiple industries, it is clear that the market for bag-type dust removal equipment—and especially high-temperature resistant filter materials—is expanding rapidly. This trend highlights strong long-term potential for the filter materials industry in China.
