Press release

Srpenica, April 26th, 2022

We are announcing new information regarding the event on April 21st, 2022, when a raw material was spilled  into the Soča River. The raw material that leaked into the Soča River is called BUILDENT WR-750. The data in the safety data sheet states  that it is a non-hazardous substance and is not harmful to river  life. According to known data, ten tons of raw material leaked.

Today, we received official results from the National Laboratory of Health, Environment and Food on the quality of the water samples taken. Immediately on April 21st, 2022, we ordered sampling of the Soča River at three different locations from TKK to Tolmin. The official results based on the chemical  analysis we received today, confirm that there was a spill of the non-hazardous raw material Buildent WR-750, that the general parameters of water in the Soča do not show dangerous properties and that the toxicity test does not show dangerous water properties. There were also no specifics that would indicate the impact of possible pollution on the water sample taken from the Močila waterworks in Anhovo.

To summarize - on the morning of 21 April 2022, we were informed that the part of the Soča River below the factory where the rapids are located was quite foamy. We immediately started with preventive measures and an examination to find the cause. Unfortunately, we found that due to human error, our raw material was spilled into the river. The intervention was completed on Thursday, April 21, 2022, and by the Civil Protection, the Soča was open for navigation on Friday, April 22, 2022, at 10 AM. There were no fish deaths, and according to official information, life in the river was not endangered.

At TKK, we have already started taking all the necessary measures to prevent a similar event from happening again in the future.
