In July 2025, the world's first 10000 ton bio based silicone rubber production line was officially put into operation in Shandong, marking a significant breakthrough in China's organic silicon industry in the field of green transformation. This production line adopts the rice husk to produce highly active silane technology developed by the Chinese Academy of Sciences, which replaces traditional petroleum based materials with biomass raw materials and achieves low-carbon production throughout the entire chain from raw materials to products.


Technological breakthrough: getting rid of oil dependence
Compared with traditional petroleum based silicone rubber, bio based silicone rubber reduces its carbon footprint by more than 60%. The Chinese Academy of Sciences team spent five years tackling the technical challenge of purifying silica from rice husk ash, increasing the efficiency of extracting silicon elements from rice husks to 92% and approaching the cost of petroleum based routes. The project leader stated, "This technology not only solves the problem of agricultural waste pollution, but also provides a sustainable raw material solution for the organic silicon industry


Industrial impact: restructuring the global supply chain
The mass production of bio based silicone rubber has attracted international market attention. The EU's "carbon footprint tracing" investigation into Chinese photovoltaic adhesive products has forced domestic enterprises to accelerate their green transformation. Hesheng Silicon Industry has partnered with Brazilian chemical giants to lay out sugarcane based methanol projects, breaking the curse of "methanol metal silicon" price linkage through an integrated model of "sugarcane planting methanol production siloxane synthesis". Dongyue Group relies on the upgrade path of the chloromethane method to reduce the energy consumption of individual units by 34%, reaching the industry average of 20% below the hard standard.


Market response: dual wheel drive of capital and policy
The secondary market has responded enthusiastically to the concept of biobased materials. As of September 30, 2025, the organic silicon sector index has risen by 18% this year, with an average increase of 25% in the stock prices of companies involved in biobased technology. The Ministry of Industry and Information Technology's "15th Five Year Plan for High Quality Development of New Materials Industry" clearly requires that the proportion of bio based organosilicon needs to be increased to 30% by 2030, and the National Manufacturing Fund has launched special support for related projects.


Industry Outlook: From "Cost Competition" to "Technology Pricing"
Analysts from Zhongyan Puhua pointed out that bio based technology will reshape the competitive logic of the organic silicon industry. As the coverage of EU carbon tariffs expands, companies with low-carbon certification will gain the ability to pay a premium. Data from Jiangxi Yongxiu's "Industrial Brain" shows that the average export price of locally produced bio based silicone rubber products is 12% higher than traditional products, and the order schedule has been extended to the second quarter of 2026.
