Its high whiteness calcium carbonate raw material, after processing, is used in the paper industry and baby peds.

Dereli Maden, founded in the 1940s by the Dereli Family. Now is runned by Yalçın Dereli as the 3rd generation.
Building on decades of expertise, the company is committed to quality, safety, efficiency and sustainability.
Dereli Maden had been the sole raw calcium carbonate raw material supplier of IMERYS’ European factories (1996–2020), Lixhe & Tunadal.
Dereli Maden has been the sole supplier of crushed marble sand of Akçansa, in Istanbul region. Its high-grade sand & aggregates contribute to energy-efficient cement production and support the construction industry’s drive toward zero-waste targets.
In marble quarrying, only a fraction of each extracted block meets the strict aesthetic and dimensional requirements for premium decorative use. As a result, substantial amounts of material often deemed unusable are dumped in residual areas.
Dereli Maden addresses this challenge through a circular economy model, transforming these leftovers into high-quality alternative sand and aggregates. This innovative process minimizes waste, preserves natural sand reserves, and significantly reduces carbon emissions, particularly in cement and concrete production.
Aligned with European sustainability goals, Dereli Maden’s approach delivers both environmental and economic benefits, further bolstering its vision. The high whiteness and purity of these repurposed marble materials also enable applications in the paper industry and baby pads, expanding the scope of sustainable resource management.
