Ulba Metallurgical Plant JSC has an Environmental Protection Action Plan for 2023–2027. The Plan provides for measures aimed at reducing emissions into the environment in the areas of air protection, water bodies, waste management, and the protection of flora and fauna. A total of 1,488.3 million tenge was actually spent on the implementation of the Plan for 2023–2025.

Ulba Metallurgical Plant’s share of emissions into the atmosphere of Ust-Kamenogorsk is negligible, accounting for less than 0.1% of the city’s total industrial emissions.

This is achieved through the use of multi-stage exhaust air purification systems. To prevent pollutants from entering the atmosphere, the plant employs cyclones, scrubbers and filters that capture up to 99% of harmful particles.

Both “dry” and “wet” purification methods are used...

Control is carried out at 242 emission sources. Monitoring is conducted using instrumental measurements and calculation methods. In accordance with schedules, employees of a specialized laboratory take samples, perform measurements, and monitor environmental performance characteristics. Measurements are taken of pollutant emissions into the atmosphere, ambient air at the industrial site, at the boundary of the sanitary protection zone in the residential area and at its border, stormwater and sewage discharges, surface water, groundwater, artesian and domestic drinking water, soil, snow cover, contamination of pedestrian and vehicle routes and production waste...
