Section 2
Company History & Milestones
The same chronology published on the Turkish page. Two generations of engineers: a company founded in 1995, trading as GESU since 1996, run as a family business since 2004.
| Year | Milestone |
|---|---|
| 1995–1996 | Company founded in 1995; the legal entity was registered with the Bursa Chamber of Commerce and Industry on 18.01.1995. Trading under the GESU name since 1996, the year İstanbul GOEMA — the Turkish arm of the German treatment company GOEMA GmbH — took a 51% share. The goal was the same from day one: European-standard engineering and manufacturing. |
| 1999 | Earliest site photograph in our archive: the Karacabey Tat Konserve treatment plant, operated by GESU (17 December 1999). |
| 2000 | First domestic biological treatment plant delivered: ARTUR — 1,600 m³/day, 8,000 population equivalent. |
| 2001 · 2003 | First industrial biological treatment plant (BANVİT, 2001), followed by the first industrial chemical treatment plant (ROBERT BOSCH, 2003). |
| 2004 | İstanbul GOEMA's shares were transferred to Dr. Sevim İbrikçi and Cem İbrikçi; GESU became a 100% Turkish-capital family company. Environmental engineer Cem İbrikçi has been general manager since the company was founded. |
| 2005 · 2007 | First factory and laboratory set up (2005); first patent registered — a peristaltic pump (2007). |
| 2008 | First ISO 9001, ISO 14001 and OHSAS 18001 certificates obtained. |
| 2012 | The year we reached three continents: first European project in Ukraine (AXOR Industry) and first African export in Ethiopia (Akşeker) commissioned; entry into the Iraqi market; first participation in the IFAT trade fair in Germany. |
| 2013 · 2014 | CNC plastic butt-welding machine added to the production line (2013); first Central Asian export with the BUYSAN GURLUŞYK project in Turkmenistan (2014). |
| 2015 | The İBRİK sub-brand was created for the equipment we manufacture ourselves — the family surname on our own products. |
| 2018 | R&D department established; CNC plastic extrusion machines joined the production line. |
| 2020 | Moved to our own factory in the Bursa Deri İhtisas ve Karma OIZ: 5,000 m² total site area, 2,000 m² enclosed production area. First Southeast Asian export in the same period, to the Philippines (Watermatic). |
| 2021 · 2022 | CNC laser cutting and CNC press brake lines commissioned (2021); robotic welding station joined production (2022) — repeatable, documented weld quality on stainless and carbon steel. |
| 2026 | AI-assisted survey, design and engineering calculators in service; more than 30 years of field experience now reaches every part of the world. |
| Today | From the jar-test laboratory to 3D design, from robotic-welded equipment manufacturing to turnkey plant installation — every stage is run under one roof. Engineering, manufacturing and site commissioning under a single point of responsibility. |
