In July 2025, the world's first 10000 ton bio based silicone rubber production line was officially put into operation in a chemical industrial park in Shandong, marking a major breakthrough in China's organic silicon industry in the field of green transformation. This production line adopts the rice husk to high activity silane technology developed by the Chinese Academy of Sciences, using agricultural waste as raw material, completely eliminating dependence on petroleum based products. The carbon emissions per ton of bio based silicone rubber are reduced by 60% compared to traditional processes, and the cost is close to the petroleum based route.


This technology has overturned the logic of the industry. "Experts from the China Fluorosilicon Organic Materials Industry Association pointed out that the promotion of bio based materials not only solves the problem of resource constraints, but also meets the needs of green trade barriers such as the EU's" carbon footprint tracing ". In July 2025, the European Union launched a "carbon footprint tracing" investigation on Chinese photovoltaic adhesive products, requiring companies to provide full chain carbon emission data from raw material extraction to product delivery, otherwise they will face high tariffs. Under the pressure of this policy, leading enterprises such as Hesheng Silicon Industry have joined forces with chemical giants to layout sugarcane based methanol projects in Brazil, breaking the curse of "methanol metal silicon" price linkage through biomass substitution.


Behind technological breakthroughs lies the deep synergy of the industrial chain. Dongyue Group has reduced the energy consumption of individual units to below the industry average through the "Low Carbon Process Route Selection Model" developed by Zhongyan Puhua; Xin'an Group has been selected as one of the "Top 500 Private Enterprises in R&D Investment" by the All China Federation of Industry and Commerce. Its self owned metal silicon smelting plant has built a vertical moat of "siloxane rubber products". Data shows that in the first half of 2025, China's photovoltaic packaging adhesive production capacity will increase by 300% year-on-year, but top companies will occupy 80% of the market share due to technological barriers.


Green transformation is not a multiple-choice question, but a survival question. "The Ministry of Industry and Information Technology's" 15th Five Year Plan for High Quality Development of New Materials Industry "clearly states that by 2028, the energy consumption of newly built single units must be 20% lower than the industry average, and the dependence on imported electronic grade silicone oil should be reduced to below 30%. In this context, Guangzhou is piloting a "trade in" recycling system, where the performance of recycled silicone rubber reaches 95% of the original raw material. The recovery rate of silicone rubber from building demolition is expected to reach 60% by 2028, giving rise to a new business model of "urban mining".
