Greening concepts

The greening of street furniture is an important component in the further development of infrastructure. In the coming years, the number of green bus shelters and pillars is to be continuously increased, making a visible contribution to improving the quality of life in cities.

The green street furniture serves as biological stepping stones, providing micro-habitats for insects and plants. To this end, the bus shelter is equipped with a drainage foam mat made of recycled material and a substrate layer of pumice stone and planted with various sedum and plant species in the interests of biodiversity. Sedum belongs to the thick-leaved family and is also known as "stonecrop". The different species bloom at different times of the year, so that the green roof can provide food for insects until late in the autumn. Other biotope elements such as lava rock or dead wood provide further food and nesting opportunities for various insects. The thick fleshy leaves of sedum species store water and cool the air through evaporation. Despite storing water, the roof planting remains relatively light: at maximum water saturation, it only weighs around 50 kilograms per square metre. Plants can also reduce air pollution by binding particulate matter and CO2. Scientific studies have shown that green spaces along inner-city streets reduce air pollution by up to 30 per cent.
