DOSAB

What DOSAB does

DOSAB (Demirtaş Organize Sanayi Bölgesi) is an organized industrial zone (OSB) located in Demirtaş, Osmangazi, Bursa, Turkey, operating under Turkish Law No. 4562 since 1990. It functions as a state-supervised industrial zone management organization providing infrastructure and operational services to 573 active member companies across 491 hectares, employing 44,000 workers whose combined exports reach $4 billion annually. The membership base is concentrated in textiles (68%) and automotive (19%), with anchor tenants including Tofaş, Astemo, Maysan Mando, Beyçelik Holding, Grammer, and Aunde. DOSAB's roots trace to the 1971 opening of Tofaş, Turkey's first automotive factory in the region.

DOSAB's core infrastructure comprises four integrated utility networks: an underground electricity distribution system (535 km of XLPE cable, closed-ring, fed by two 100 MVA transformers, achieving 0.5% loss vs 3% industry average); natural gas distribution to 187 subscribers (~150.9 million Sm³ in 2022); water distribution to 432 drinking and process water subscribers (11.4 million m³ in 2024); and Turkey's first and largest industrial wastewater treatment and recovery facility (82,500 m³/day, with MBR and RO systems producing ~4 million m³ of recycled process water annually, 176 million TL investment). A proprietary SCADA system, commissioned in 2012, provides real-time monitoring and control from a central facility, supported by a fiber optic ring, an in-house data center, and a 3 MW rooftop solar plant generating ~4.1 million kWh/year. DOSAB also operates add-on facilities including a kindergarten, restaurant, mosque, occupational health unit (OSGB), and a fuel station (in partnership with OPET since January 2026).

DOSAB generates revenue primarily through usage-based monthly billing for electricity, natural gas, water, and wastewater services, supplemented by annual membership/subscription fees and one-time land sales and leases for the 342 industrial parcels. The 2026 operating budget of 1,371,909,000 Turkish Lira reflects continued infrastructure investment, including Phase 2 wastewater recovery with BUSKİ and a new Management Center targeted for 2027 completion. The organization holds ISO 9001, ISO 14001, ISO 45001, and ISO 50001 certifications, and has received four environmental awards for being Turkey's most environmentally friendly OSB.
