The "Kujawy" Cement Plant, located in Bielawy in the Barcin municipality of the Kuyavian-Pomeranian Voivodeship, is a key industrial facility in Poland, owned by the international concern Holcim. Situated approximately 40 km south of Bydgoszcz, the plant consists of a cement factory and limestone quarries, from which raw materials are extracted on a large scale, with an annual production reaching 4.8–5.2 million tons. The plant produces various types of Portland cement using a modern production line. A notable innovation is Poland's first automated laboratory in the cement industry, launched in 2018.
The history of the plant dates back to the 19th century when, in the early 1860s, large-scale limestone extraction began, contributing to the development of the lime industry. During the interwar period, the enterprise transformed into a dynamically operating industrial plant, and during World War II, production focused on fertilizer lime. After the war, the plant was nationalized and continued to develop throughout the communist era, undergoing numerous modernizations and investments. In 1995, it was acquired by the French concern Lafarge, which led to further modernization and increased efficiency.
Among interesting facts, the "Kujawy" Cement Plant is the only site in northern Poland with documented rich limestone deposits. Additionally, worker housing estates were built around the plant, contributing to the development of the local community. In 2015, following the merger of Lafarge and Holcim, the plant was renamed Holcim. Throughout its long history, the "Kujawy" Cement Plant has not only played a key role in the Polish construction industry but has also been recognized for its pro-environmental initiatives and adaptation to modern production standards.
