Our company owns 17 fully automated calcium oxide production lines, three calcium hydroxide production lines, and nine calcium carbonate production lines.
Its annual output is 200,000 tons for nano-calcium carbonate, 200,000 tons for calcium hydroxide, 160,000 tons for light calcium carbonate, 360,000 tons for heavy calcium carbonate, and 1 million tons for calcium oxide — positioning us as one of the most capable calcium product manufacturers in the world.
As a premier Lime Powder Calcium Hydroxide supplier serving Istanbul and Turkey, we provide consistent quality, competitive pricing, and full technical support for local and regional buyers.
Understanding the local industrial landscape and commercial demand in Turkey's largest city
Istanbul is one of Europe's fastest-growing metropolitan areas, with massive ongoing urban renewal, earthquake-resistant retrofitting projects, and new infrastructure investments. Calcium hydroxide (slaked lime) is a critical material in mortar, plaster, and soil stabilization — demand has surged significantly over the past decade as the city modernizes its aging infrastructure.
Istanbul and its surrounding Marmara region host thousands of manufacturing facilities — from steel mills and chemical plants to paper mills and rubber factories. These industries require high-purity calcium hydroxide for pH control, flue gas desulfurization, wastewater treatment, and as a chemical reagent. Turkey's industrial output continues to expand, driving consistent demand for quality lime powder suppliers.
As a megacity of over 15 million residents, Istanbul operates one of the most extensive water treatment networks in the region. Calcium hydroxide is essential for softening water, neutralizing acidic effluents, and treating industrial wastewater. Municipal authorities and private operators alike rely on reliable lime powder suppliers to maintain environmental compliance and public health standards.
The Thrace region adjacent to Istanbul is a significant agricultural zone. Farmers use hydrated lime (calcium hydroxide) to adjust soil pH, improve soil structure, and control plant diseases. As sustainable farming practices gain traction in Turkey, demand for agricultural-grade lime powder continues to grow steadily across the region.
Turkey's alignment with EU environmental standards has accelerated the adoption of flue gas desulfurization (FGD) systems, acid neutralization processes, and heavy metal precipitation techniques — all of which require calcium hydroxide. Istanbul-based industrial operators face increasing regulatory pressure to adopt cleaner production methods, creating new market opportunities.
Istanbul's position at the crossroads of Europe and Asia, combined with its world-class port infrastructure, makes it an ideal import and distribution hub for calcium hydroxide sourced from China. Shipments from Shandong Useen can reach Istanbul efficiently via established sea freight routes, ensuring competitive lead times and cost-effective bulk delivery for Turkish buyers.

Key developments shaping the future of lime powder and Ca(OH)₂ supply chains in the region
The Turkish construction sector is rapidly adopting green building standards, including LEED and BREEAM certifications. Calcium hydroxide-based lime mortars and renders are gaining renewed interest for their breathability, low carbon footprint, and compatibility with natural stone — key attributes for heritage restoration projects in Istanbul's historic districts.
Turkey's EU accession process and domestic environmental legislation are compelling industrial operators to install flue gas desulfurization systems. Calcium hydroxide is the primary reagent in dry and semi-dry FGD processes, creating a structural growth driver for high-purity lime powder across Turkey's energy and heavy industry sectors.
Advanced nano-scale calcium products, pioneered by manufacturers like Shandong Useen, are beginning to penetrate Turkish industrial markets. Nano-calcium hydroxide offers superior reactivity and surface area, enabling new applications in coatings, advanced plastics, and high-performance rubber — sectors where Turkish manufacturers are increasingly competitive globally.
Bilateral trade between China and Turkey has grown substantially, with improved logistics along the Belt and Road Initiative routes. This makes Chinese calcium hydroxide suppliers more accessible to Istanbul-based buyers, offering cost advantages without sacrificing quality — particularly for bulk industrial procurement.
Rising health consciousness and expanding pharmaceutical manufacturing in Turkey are driving demand for ultra-pure, food-grade calcium hydroxide. Turkish food processors and pharma companies increasingly seek certified, traceable Ca(OH)₂ from ISO-compliant global suppliers — a segment where Useen Calcium excels.
Istanbul's industrial buyers are placing greater emphasis on product consistency and supply chain reliability. Fully automated production facilities — like Useen's 17 CaO and 3 Ca(OH)₂ production lines — provide the batch-to-batch uniformity that modern Turkish manufacturers demand for high-precision applications.
World-class R&D partnerships driving next-generation calcium product development
Innovation is at the core of everything we do. In recent years, we have made significant investments in R&D, focusing on the development of new technologies and next-generation calcium products. Our company has established close "industry-university-research" cooperation relationships with well-known foreign industry experts, the Institute of Process Engineering of the Chinese Academy of Sciences, Tsinghua University, China University of Geosciences, Beijing University of Science and Technology, Shandong University, and more.
Through our industry-university-research partnerships, we have established strong capabilities in applied research, product development, and advanced process engineering. These collaborations allow us to continuously evolve, improve our formulations, and meet the changing demands of global industries — including the rapidly growing Turkish and Istanbul markets.
Our company is the first in China to apply nano calcium carbonate to PE blow molding products, which can replace traditional filling materials and has excellent performance — a breakthrough that is now attracting significant interest from Turkish plastics manufacturers.
