For electricity saving, our company uses waste heat recovery system which uses waste heat coming from production process. The company signed an agreement with Chinese Catic company on 21 April 2014 to build a 12 MW/hour capacity waste heat recovery power plant.
On 26 November 2015 the system started to generate electricity and right now the system meets 21% electricity requirement of Goltas.
Financers of this project are European Bank for Reconstruction and Development(EBRD) and Turkish Sustainable Energy Financing Facility(MidSEFF). "The most energy efficient project" financed in Turkey and also granted award by EBRD. Recovered energy from the waste-heat project can supply up to 15.000 houses.

1st Line Electro Filter Capacity Increase Investment in 2002-2007:
An agreement was signed with KHD on 19 April 1998 in order to increase 2000 ton/day capacity of 2nd line to 4000 ton/day capacity. 600.000 ton increase in Clinker production has been achieved. Unit cost of 1 kg clinker is decreased as 850 kcal/kg energy requirement decreased to 780 kcal/kg.
2nd Line Cement Plant Pre-calcination Capacity Increase Investment in 1998-2006:
In parallel with 3rd raw mix(farin) mill project, 10.000 ton stock capacity raw mix(farin) homogeneous silo was built. Raw mix(farin) is homogenized with new technology and this increased quality in clinker production. At the same time raw mix(farin) silo which is planning to be built in the future and required for 2nd cement line capacity increase project, is ready.
3rd Raw Mix(Farin) Homogeneous Stock Silo Installation Investment in 1996 – 1999:
220 ton/hour capacity raw mix(farin) mill was built to increase raw mix(farin) capacity which affects 2nd clinker production line. When electricity costs more in times of the day the production can be easy by easing raw mix(farin) production so a lot of money saved. Also raw mix(farin) necessary for 2. cement line capacity increase which is planning to be built in the future, is produced.
3rd raw mix(farin) Mill Unit Installation Investment in 1996 – 1999:
Cement was transferred to silos with high pressure air generated by compressors,
By this investment, cement is transferred to silos via air slide and bucket elevator. Also, electricity consumption has been seriously decreased.
Project was completed in December 1997 and was commissioned.
Cement Air Slide Transfer System Installation Investment in 1996 – 1997:
10.000 ton stock capacity cement silo was constructed. In this facility, there are 2 cement packaging facilities each has capacity of 100 ton/hour and 2 cast cement loading facility. Loading capacity is increased 67% and stock capacity is increased 100%. Facility was completed in December 1997 and started production.
