The annual production capacity is about 5.17 million tons! Hubei has announced 13 production lines of phosphogypsum to produce sulfuric acid and cement this year.

According to the statistics of China Cement Network, Hubei Province has publicized 13 production lines of phosphogypsum-based sulfuric acid co-production cement since this year, with a total clinker production capacity of 16667 tons per day, equivalent to about 5.17 million tons per year (310 days). Compared with the Top 100 List of China's Cement Clinker Production Capacity in 2025, the total annual production capacity of clinker in Hubei Province is 64.763 million tons, and the production capacity of these projects accounts for less than 8%. Looking at the proportion

alone, it seems insignificant. But the original intention of phosphogypsum acid co-production cement is to eliminate phosphogypsum and produce sulfuric acid, and clinker is just a by-product "incidentally", but the market does not see what your "original intention" is, but only how many goods you pour into the market. At present, the cement industry has serious overcapacity and low utilization rate, and the price has been rolling up for a long time near the cost line. Capacity removal and reduction have become the top priority of the whole industry. When the phosphogypsum co-production project pours low-cost clinker into the market as a "by-product"-the marginal cost per ton of clinker is only 80-150 yuan, which is 30% -50% lower than traditional process, the traditional cement enterprises are unable to cope at all. What needs to be

more vigilant is that from the publicity rhythm, there will be more similar projects queuing for landing in the future.
