In October 2025, China's organic silicon industry achieved a milestone breakthrough - the world's first 10000 ton bio based silicone rubber production line was officially put into operation in Shandong. This project uses agricultural waste such as rice husks as raw materials, and through the high activity silane technology developed by the Chinese Academy of Sciences, completely eliminates dependence on petroleum based raw materials, reducing carbon emissions per ton of product by 40% compared to traditional processes. This technological breakthrough marks a crucial step in the transformation of the organic silicon industry from a "resource consuming" to a "green circular" model.


Industry data shows that the production of organic silicon monomers in China increased by 6.46% year-on-year in the first three quarters of 2025, but the capacity utilization rate was only 76.15%, indicating that the industry as a whole is still in the stage of overcapacity. The implementation of bio based projects not only alleviates resource constraints, but also opens up high-end markets such as the European Union through carbon footprint advantages. It is reported that the silicone rubber produced by this production line has passed the international biobased material certification. The first batch of products will be used for the thermal management module of new energy vehicle batteries. Its thermal conductivity is 30% higher than traditional materials and can meet the extreme temperature difference requirements of -40 ℃ to 85 ℃.


At the policy level, the Ministry of Industry and Information Technology's "15th Five Year Plan for High Quality Development of the New Materials Industry" clearly requires that the unit energy consumption of newly built organic silicon plants after 2026 should be 20% lower than the industry average, and promote the popularization of low-carbon processes such as fluidized bed reactors. Experts point out that the large-scale application of bio based technology will reconstruct the global organic silicon industry chain. It is expected that by 2030, the proportion of bio based organic silicon products in China will exceed 15%, becoming a new growth pole in the industry.
