EGESIL KIMYA SANAYI

Egesil is a joint venture between Evonik (51%) and Ege Kimya (49%) established for the production of precipitated silica.
In October 2019, Egesil Kimya Sanayi has put a new precipitated silica manufacturing facility into operation at its site in Adapazari in North Türkiye. This increases the annual production capacity for precipitated silica at this site by 40,000 metric tons and created around 40 new jobs. The company has invested a sum in the low double-digit million euro range in the construction of these facilities.
The new plant in Adapazari enables the joint venture partners to also cater to their customers in Türkiye , Eastern Europe, and the Middle East with more regionally produced silicas using the short delivery channels to which their clients are accustomed.

Im Oktober 2019 hat Egesil Kimya Sanayi an seinem Standort in Adapazari in der Nordtürkei eine neue Produktionsanlage für gefällte Kieselsäure in Betrieb genommen. Damit erhöht sich die jährliche Produktionskapazität für gefällte Kieselsäure an diesem Standort um 40.000 Tonnen und es entstehen rund 40 neue Arbeitsplätze. In den Bau dieser Anlagen hat das Unternehmen einen niedrigen zweistelligen Millionenbetrag investiert.
Die neue Anlage in Adapazari ermöglicht es den Joint-Venture-Partnern, auch ihre Kunden in der Türkei, in Osteuropa und im Nahen Osten mit mehr regional produzierten Kieselsäuren auf den gewohnt kurzen Lieferwegen zu versorgen.
