Environmentalist Approach

As Goltas Cimento, we continue our investments in the environment and energy efficiency in our factory in line with the principles of continuous improvement and continuous development which are indispensable for the industry. The Company aims to continuously improve its impact on the environment and its activities to prevent pollution. Ali has proved that he does not compromise the principle of environmental sensitivity with the “ENVIRONMENTAL PERMIT CERTIFICATE on Air Emission and Waste-water Discharge which he has received from the Ministry of Environment and Urbanization.

1-Studies on flue gas emissions and ambient air quality:

1.1 Flue Gas Emissions / Online Emission Tracking System

Effective filter systems have been installed at the dust outlet points to prevent dust from spreading to the environment. The effectiveness of these filter groups in the scope of confirming measurements is monitored.

In order to reduce the dust emissions of 50 mg / Nm3 at the main furnace of the rotary kiln to below 10 mg / Nm3, 3 electro filter / bag filter transformations were made in 2015. and also in 2015, a pebble filter in our facility was completely changed to bag filter and a total investment of 4.500.000 Euro was realized. In the warranty measurements performed after the filters were commissioned, dust values were measured below 5 mg / Nm3. With this investment in the main emission sources, an increase in dust holding efficiency has been achieved.

Within the scope of SEOS, instant emission tracking is carried out by on-line gas and dust analysers with continuous emission measurement devices in our Main Chimneys. and readings are monitored on-line by the Ministry of Environment and Urbanization and Provincial Directorate of Environment and Urbanization. It is also controlled by the competent authorities that the dust and gas emission values do not exceed the legal limit. Within the scope of air pollution control, periodic confirmation measurements are also made by the accredited organizations in order to ensure legal obligations arising from environmental legislation.

An efficient maintenance method is used to ensure the continuous operation of gas and dust emission measurement devices. 

In order to reduce the dust emissions in the Rotary Kiln II chimney to 10 mg / Nm3, an electro filter / bag filter conversion is planned and the estimated budget is 1.200.000 euro.

1.2 Ambient Air quality improvements;

For the coal stock areas, dust curtain wind screens are placed around the stock area and the effect of wind is reduced by constructing automatic sprinkler system. Within the coal stock hall, the areas where the work machines are operated are prevented from dust by continuously irrigating.

There is a closed clinker silo for stocking the clinker produced.

Concrete roads in the factory are continuously swept with a road sweeping machine and are irrigated on days without rain. The raw material transportation paths are constantly kept moist and dust formation is prevented.

In our plant, with two high-capacity dust suction machines, one is stationary in the packaging unit and the other is mobile, the dusty area is cleaned by suctioning of the dust and therefore the dust emission is blocked. As a result of the entire filtration process in the plant, the collected material is recycled to the closed system. In out plant, the bag filters are used in order to prevent dust in dust sources.

2. Works for water management

2.1 Waste water from production facilities:

There is no waste water during clinker and cement production in our plant.
Two pools are constructed for the waste water generating from the waste heat, and the water accumulated in these pools is used in production units for use in cement production stage.

2.2 Surface waters from the rain

For the surface water generated from the rain in the facility, 3 partitioned settling ponds were constructed in 3 different regions; and accumulated water is used in the coal storage area for sprinkling and dedusting and road irrigation. Within the scope of Environmental Legislation, environmental permit exemption for waste-water discharge of surface waters from precipitation is taken. The discharge of these waters into the receiving environment is prevented.

Waste water generated by washing car and washing machines is transported to the surface water collection pool of the coal stock area after passing through the oil trap, and used there for dedusting of the coal.

2.3 Domestic waste water

There is a 100 m3 / day Sequential Batch Biological Package Domestic Waste-water Treatment Plant for domestic waste-water (WC, Bathroom, Dining Hall, Social Facilities, Administrative and operational building) arising from the employees. The waste-water is discharged to the dry river bed after the treatment in the treatment plant.

The results of samples taken from the waste-water treatment plant by the Accredited Laboratory every two months meet the SKKY limit values and the legislative obligations are fulfilled.

3. Management of waste generated at the facility:

3.1 Waste Management

With its Waste Management System since 2008, Goltas Cimento ensures collection, temporary storage and disposal of all hazardous and solid wastes in accordance with the law. According to the legislation, the storage area has been constructed for the temporary storage of the wastes arising from the routine activities of the facility; and Temporary Waste Storage Site Permit has been obtained from Provincial Directorate of Environment and Urbanization. The waste generated in the facility (hazardous waste, non-hazardous waste, waste oil, contaminated wastes, oil and air filters, waste battery, waste battery, waste cartridge-toner, medical waste, waste, etc.) are stored in the relevant compartments in the Temporary Waste Storage area. Stored waste is sent to disposal or recycling facilities approved and licensed by the Ministry, or having the environmental permits and licenses.

The ground of metal scrap yard is covered with concrete and the contact of the scrap with the soil is prevented.

3.2 Recycling of the waste of packaged products put on the market

Within the scope of our 2017 obligation which we have fulfilled with ÇEVKO, which is authorized by the Ministry of Environment and Urbanization;

  • 19,567 tree cuts have been prevented (391 acres of forest land)
  • 30.495.745 m3 of water has been saved (annual water consumption of 174 households)
  • 4.799.936 kWh electric energy savings (annual electricity consumption of 1738 households)
  • 10.528 litres of fossil fuel have been saved and contributed to the environment. (Source; ÇEVKO)

4. Energy savings and reduction in CO2 emissions

4.1 Electricity generation from waste heat (MidSEFF award)

The 12 MW Capacity Waste Heat Power Plant was commissioned in November 2015 for the recovery of heat from the chimneys and the recovery of the heat thrown into the atmosphere; and 10 MWh electricity have been generated. 21% of our factory's electrical energy needs is provided from the Waste Heat Power Plant. With this project, we prevent the emission of 50,656 tons of carbon a year and contribute to the environment as much as the amount of oxygen provided by approximately 2,300,000 trees. The energy recovered by this project corresponds to the electricity needs of 15,000 houses.

An investment of 20 million dollars has been made for 12 MW power generation.

Goltas Cimento A.S. was awarded with ”The Highest Energy Saving Project“ financed by Medium-sized Sustainable Energy Financing Program (MidSEFF), a program of European Bank for Reconstruction and Development (EBRD) and its partners, for her investment of "Electricity Generation from Waste Heat‘‘.

At the end of 2017, VCS Carbon Certification was obtained in order for the waste heat recovery power plant project to gain more importance; and the right to trade Carbon in the international market has been obtained.

4.2 Savings on cement and clinker production:

In order to decrease the cement grinding energy in 2015, the vertical cement mill with rollers was established. Comparing to the ball mills, it produces cement with approximately 5 kWh / ton less energy. The investment cost of this project is 16.500.000 Euro.

The ventilators used in the system have been adjusted to rotation manner and the energy consumption of the fans has been reduced by approximately 20%.

The lighting fixtures used in the factory have been transformed into energy-efficient luminaries, saving about 30% energy from lighting electrical energy costs.

5kWh / ton of electricity has been saved by separator change made in the cement mill-3 process.

The heat requirement of our factory has been obtained from the heat of the waste gases and 2 boilers in the boiler room have been disabled. Approximately 5 tons of fossil fuel consumption per day has been saved.

5. Environmental and social sensitivity

Our company, which maintains its sensitivity on the environment with afforestation and green field studies, makes maximum effort to carry these services to the future.

5.1 Forest areas

As a result of the agreement with the Ministry of Forestry in the early 1980s, afforestation. rented 111 hectares of land from the General Directorate of Forestry for 49 years with the afforestation. In the 95s, 33 hectares were added and the total area increased to 144 hectares. There are cedar, red pine and black pine plantations in this area in different ages. Approximately 20,000 saplings are planted on a special forest area each year and regular annual maintenance is carried out.

5.2 Tree planter

With the help of the planter vehicle purchased by our factory in 1997, which can transport large trees, public and private institutions in and around Isparta are assisted on tree planting. Tubular pine saplings are also grown and planted in the forest area.

5.3 Grass fields

Germination has been conducted in the field of 40.000 m2. Renewal and maintenance works for trees are in progress. The factory entrance side of the highway and the side of the plant have been refined and the plantation works have been completed.

6. Rehabilitation and reclamation projects in mining sites

In addition to many studies we have carried out in order to reduce the negative effects of the quarry enterprises on the environment, we continue the rehabilitation works at the mine sites where we have completed the mining as planned.

  • 1.2 hectares in our limestone quarry,
