Environmental Policy of GIKIL d.o.o. Lukavac provides a framework for setting and confirming operational objectives and is aligned with the organizational context.

Senior management will regularly review the effectiveness of the environmental management system and environmental objectives to ensure their effectiveness and continued applicability.

All employees have a responsibility to work in an environmentally acceptable manner to avoid any harmful effects of their work on the environment.

 

With regard to air protection and atmospheric emissions, in recent times maximum attention has been paid to technological improvements in the production of raw coke gas and coking ovens.

In addition to improving technical accuracy when selecting coal blends, it is very important to have regular and unscheduled crusher overhauls for precise grinding of the blend, coke ports and ducts, as well as firewall replacement. In addition, an overhaul of the charging machines was carried out for the proper filling of the coking ovens, as well as a general overhaul of the coke gas suction system.

Repairs to the damage to the coke oven walls of the V-Coke Battery are underway and management has decided to replace the battery’s complete platform.

Wall repair includes coke oven ceramic welding. Apart from the fact that it is a very complex and demanding job done at very high temperatures, the refurbishment is progressing well and about 50% of the work is already completed. All chambers, or ovens, will be renovated in this way before the end of the year. In addition, besides replacing the entire platform, it not only extends the active operation of the battery and makes better use of the coke extraction process, but above all contributes significantly to reducing harmful emissions which is the most important goal.

Additional coke battery production and environmental improvements will be achieved early next year when two new machines will be installed

This is a smokeless charging machine and a coke receiving machine that didn’t work before. With new machines, there will be no more waste or emissions. They have been ordered and are currently in production, the commissioning deadline is February 20th and their commissioning is scheduled for February 2023. All this is not only for the purpose of improving production processes and techniques, but also to reduce uncontrolled emissions into the atmosphere.

Significant reductions in air pollutant emissions have also been achieved by terminating activities at the Power plant. A completely new gas line was put into operation to supply gas to the boilers. Smoke duct, burner casings, combustion chambers, sieve tubes were replaced, walls around burners were repaired, external air fans and walls were repaired, and boiler desludging was carried out. A new water heater, economizer and air heater were installed in the chimney to improve combustion in the boiler and reduce emissions.

The PLC control system was also replaced, achieving improved regulation, air heating, the possibility of adding more air to the burner and a better gas-air mixture, better combustion formation which reduces emissions into the air.

There are currently no emissions or pollution from the Fertilizer plant, specifically since October 2021, when the Management decided to temporarily suspend the operation of the Fertilizer plant.

The decision was made solely due to the cessation of production caused by long-term economic and financial consequences and realized losses. All labour force is retained and distributed to other plants and departments.

On the other hand, at the maleic anhydride plant, the catalyst has been replaced and the compressor has been overhauled, and new investments are underway.

Replacing the catalytic converter significantly reduces the concentration of carbon monoxide in the exhaust gas. Here it is worth mentioning that the project to reduce the concentration of xylene in the exhaust gas is expected to be implemented by the end of this year. Another major investment is underway in this plant. This involves purchasing a new reactor that will further reduce harmful emissions into the air. At the same time, we are completing the technological process related to wastewater treatment technology at AMK plant.

Special care is taken to avoid ground emissions and harmful effects on the ground. Following the success of the land remediation project, the bio-recovery potential of areas devastated by industrial waste was explored with the help of the Cantonal Ministry of Spatial Planning and Environmental Protection and other participants.

One of the main activities that we quickly carried out at Global Ispat Koksna Industrija d.o.o. Lukavac in the past time is implementing projects to prevent and reduce the emission of harmful substances into water, as well as protect water sources in general.

For the collection of technological, precipitation-polluted, and sanitary-faecal wastewater, as well as for their purification and disposal, all technical-investment paperwork has been completed at the level of main, implementation projects. A separate sewage system is specified in the project documentation.

At the coking and coal storage depots, gravity filtration equipment has been built. All are working and delivering the required results.

The most important aspect is that the cleaned sediment is returned to the landfill and used as a raw material in the production process. In fact, the suspended solids in the primary sediment are particles of coal and coke. As a result, there is no discharge or overflow into other flows and the specified limit values ​​are met.

At the Filter Station, the quartz sand was replaced in the sand filters and the anti-corrosion protection was completed.

At the same time, the preliminary and main project to collect, treat and discharge industrial wastewater from the filter station was completed. This is one of our larger and most important projects, along with the project for water license. The works have already started and we will see immediate effect as this will prevent suspended solids from entering the Jala River.

The treatment and use of disposal of waste is carried out according to the provisions of the Law on Waste Management and the Waste Management Plan. Waste monitoring has been established, the place of its generation has been located, and register of waste by type, quantity, treatment method and transportation are kept properly.

                                                                      Slika 1. Upravljanje otpadom

In addition, the construction and equipment project for the hazardous waste and other waste storage plant was implemented to ensure storage conditions, in accordance with the law provisions.

                                                                       Slika 2. Skladište opasnog otpada

Another novelty is that the entire GIKIL complex collects and sorts five types of packaging, wood, scrap paper and cardboard, in cooperation with the local community, namely Lukavac’s schools and citizens’ associations to which all these are donated. All this implies that the company is in the midst of major transition and major changes and that we want to show our social responsibility as much as possible, all with the aim of preserving the environment.

                                                                   Slika 3. Razdvajanje otpadnog materijala 

We are actively working to spread awareness among employees, customers and suppliers about the environmental aspects of GIKIL, with permanent openness to the public whenever they are interested.
