7月3日消息：比利时化工企业索尔维宣布，其青岛工厂与韩国群山工厂的沉淀法白炭黑生产线正式投产。该生产线采用获得国际可持续发展与碳认证联盟（ISCC Plus）认证的废砂作为原料，这套循环生产模式后续将在全球推广。
今年早些时候，索尔维在意大利里窝那建成全球首座生物循环型白炭黑工厂。该工厂利用稻壳灰生产轮胎用高分散白炭黑，开创了生物质原料制备白炭黑的新工艺。此次亚洲落地废砂制白炭黑生产线，是该企业循环材料发展路线图上又一个里程碑事件。
两条循环生产线的建设，主要为适配轮胎行业目标——到2030年实现40%原材料取自循环再生资源，同时巩固索尔维在低碳交通材料核心供应商领域的行业地位。
财务层面，2025年索尔维白炭黑业务经营承压，销售额达5.15亿欧元，同比下滑5.1%，内生性营收下降2.6%，市场整体轮胎需求疲软是业绩走低的首要原因。
即便营收承压，索尔维仍持续加快低碳转型进程，积极用废砂、生物质原料替代传统矿物原料，向轮胎厂商供应低碳白炭黑产品。
。Solvay Launches Recycled Silica Production Lines at Two Asian Sites
News dated July 3: Belgian chemical firm Solvay announced the official launch of precipitation silica production lines at its facilities in Qingdao and Gunsan, South Korea. The lines adopt ISCC Plus certified waste sand as raw material, and this circular manufacturing model will be rolled out worldwide later.
Earlier this year, Solvay opened the world’s first bio-circular silica plant in Livorno, Italy. The facility produces high-dispersion silica for tires using rice husk ash, pioneering a production route based on biomass feedstock. The new waste sand lines in Asia mark another milestone in the company’s circular material roadmap.
The development of these two circular production lines mainly serves the tire industry’s target of sourcing 40% of raw materials from circular sources by 2030, while strengthening Solvay’s position as a key supplier of low-carbon mobility materials.
Financially, Solvay’s silica business faced headwinds in 2025, posting sales of 515 million euros, a year-on-year drop of 5.1% with an organic decline of 2.6%. The downturn stemmed primarily from sluggish overall demand across the tire market.
Despite revenue pressure, Solvay keeps ramping up its low-carbon transition. It actively replaces conventional mineral feedstock with waste sand and biomass to supply low-carbon silica products to tire manufacturers.
