On Tuesday, January 30, 2018, the installation of rail noise absorbers with the BRENS STERED water retention function was started as part of the modernization of the tram lines in the city of Košice, namely the SNP Class. The tramway is led in a separate center of the track, and between the intersections, the water absorbers of the synthetic and rubber recycled water absorbers will be inserted into the two tracks. The surface will be made up of a vegetation cover of SEDUM rows (as it was applied last year in Ostrava) as well as a naturalized artificial lawn. In total, an 8,300-square-foot track, ie approx. 1 185 m double track.

The city of Košice is the first city in the Slovak Republic to use rail noise absorbers with a water retention function to solve environmental liability for the construction of the city railroad track.

In Košice, an average of 600-650 mm of water is consumed during the year . Controlled by absorption in the absorber parts, the majority of the absorber is captured and backed  into the city space, which cools, humidifies and at the same time dampens noise and reduces dustiness. This segment of the tram line absorbs during the year up to 430 thousand. liter of water . Imagine the amount of water in 20 indoor garden pools measuring 3.00 x 6.00 m with a depth of approx. 1,20 m or 1/5 Olympic size pool.

From the point of view of the closed (non-waste) economy, the BRENS STERED absorber was processed and subsequently processed in the production of the individual parts of the absorbers:

• 223 800 kg of waste synthetic textiles from the automotive industry, ie waste from production approx. 74,600 new passenger cars.
• 366,583 kg waste rubber technical rubber, ie for the controlled disposal of 52,370 pieces of used tires.
