Industrial Mineral Supply in the Historic City of the Western Black Sea
With its forest-covered mountains, historic timber architecture, and developing industry, Kastamonu is one of the deep-rooted cities of the Western Black Sea region. Sectors such as woodworking, food industry, livestock farming, and mining, alongside growing municipal infrastructure investments, create demand for industrial minerals in various fields in this city. Its broad geography spanning 20 districts — from the mountainous northern coasts to the plains in the interior — contains different economic profiles, each carrying its own product needs. Say Quartz supplies quartz sand, silica sand, and filter sand to Kastamonu's 20 districts from its production facilities in Tekirdağ Çorlu.
Construction Sector in the Central District and Tosya
Kastamonu's central district is the area where the city's most intensive construction takes place. Residential projects, public buildings, and commercial structures continuously generate demand for quartz sand-based construction chemicals. Quartz sand is used across a wide spectrum from grout filler materials to exterior facade moldings, from plaster additives to floor coating applications. Kastamonu's cold winter conditions highlight the freeze resistance of construction chemicals, making raw material quality an even more decisive factor.
Tosya, as one of Kastamonu's most populous districts, forms its own economic center in its surroundings. In the district known for rice production, construction activities are also intensive alongside agricultural infrastructure. Taşköprü, beyond garlic production, is a district with developing industry and commerce that shows increasing demand for building materials. Building projects in both districts utilize Say Quartz's quartz sands in 12 different grain sizes. The grain size range from 100 microns to 32 millimeters allows different applications — from fine grout filling to coarse facade molding production — to be met from a single supplier.
Drinking Water Treatment and Filtration
Kastamonu's mountainous geography allows drinking water to be sourced largely from natural springs. However, these waters need to be filtered before being delivered to the network. The increase in turbidity in spring waters during snowmelt and rainy periods makes regular maintenance of filtration systems mandatory. Filter sands are used at many points from the main treatment facility in the central district to regional units in Araç, Daday, and Devrekani.
Say Quartz's filter sands in 11 different types with a size range from 0.4 millimeters to 32 millimeters meet the needs of different treatment stages. In Black Sea coastal districts such as İnebolu, Cide, and Abana, there is demand not only for filter sands but also for products such as hydroanthracite and activated carbon for municipal water treatment systems. Activated carbon offers an effective solution especially for removing organic compounds and color-causing substances from water. The same product groups are also used in small-scale treatment facilities in Çatalzeytin and Doğanyurt. In Bozkurt district, the reinforcement of water treatment infrastructure due to flood risk has increased demand for filter materials.
Mining and Industrial Applications
Küre district is known for its industrial heritage as one of Turkey's oldest copper mining regions. Silica sand is used in sandblasting and surface preparation operations at ore processing facilities in the region. Say Quartz's silica sands in 7 different granulometries are preferred in the maintenance processes of mining equipment and in cleaning metal surfaces. The hardness and grain size distribution of sandblasting sand are parameters that directly determine surface preparation quality.
Industrial mineral products are also needed for sanding and surface preparation applications in woodworking facilities in Azdavay and Hanönü districts. Kastamonu's strong forestry tradition keeps wood surface preparation operations in the timber and furniture sector on the agenda. In İhsangazi, silica sand-based products are also used in small-scale manufacturing workshops.
Agricultural Irrigation and Water Management
In Kastamonu's interior districts, agricultural production is the main pillar of the city's economy. Filter sand is regularly renewed in the filters of agricultural irrigation systems in Pınarbaşı, Seydiler, and Şenpazar districts. Rice, wheat, and fruit production in these districts requires water to reach the fields in high quality without interruption. There is also demand for similar products for drip irrigation systems in agricultural lands in Ağlı district.
While Araç district stands out with its fertile agricultural lands in its basin, Devrekani is also a region where livestock farming and agriculture are conducted together, making investments in water management infrastructure. Tosya's rice fields require special irrigation arrangements, and Say Quartz's filter sands are also used in the filtration of these systems.
Sports Facilities and Social Spaces
Artificial turf facilities and children's playgrounds throughout Kastamonu are among municipalities' social investments. Artificial turf facilities in the central district, Tosya, and Taşköprü fill with specially granulated artificial turf field sand. Playground sand is used conforming to hygiene and safety standards in parks in all of Kastamonu's districts. Quartz sand products are also utilized in landscaping works at coastal recreation areas in İnebolu and Cide.
