欧盟委员会周五表示，已对瑞士公司Omya展开反垄断调查，怀疑其在该公司向造纸产品生产商供应碳酸钙方面存在滥用市场支配地位的行为。
The EU Commission on Friday said it had opened an antitrust investigation into Swiss company Omya, for possible abuse of its dominant position in the supply of calcium carbonates to producers of paper products.
委员会称，Omya可能要求造纸行业的客户从该公司购买全部或大部分碳酸钙。Omya尚未立即回应置评请求。
The Commission said Omya might have required customers in the paper industry to purchase all or most of their calcium carbonates from it. Omya did not immediately respond to a request for comment.
碳酸钙是造纸过程中的重要原料，用于降低生产成本并提高纸张和纸板的亮度、不透明度、平整度和可印刷性。
Calcium carbonates are an important input in the paper manufacturing process, where they are used to reduce production costs and improve brightness, opacity, smoothness and printability of paper and cardboard, the Commission said.
委员会表示，Omya的这种行为可能限制了其他碳酸钙供应商在欧洲市场的竞争能力。
It said Omya's practices might have limited the ability of other suppliers of calcium carbonates to effectively compete for customers in Europe.
委员会补充说，‘具有竞争力且价格合理的碳酸钙供应非常重要，因为这可以降低造纸厂的投入成本，最终使纸张和纸板产品的消费者受益。’
"Competitive and affordable supplies of calcium carbonates are important, because these can reduce input costs for paper mills and ultimately benefit consumers of paper and cardboard products," it added.
