Flowers and plants used to block traffic noise and pollution

These are also easy-to-install, long-lasting, and recyclable walls that add biodiversity to any location

According to the European Environment Agency, environmental noise contributes to 48,000 new cases of ischaemic heart disease a year as well as 12,000 premature deaths. Typically, governments build concrete or plastic walls around highways, but now – there is a better way to protect people from noise pollution.

German company Naturawall has come up with a green and easy-to-install solution to create walls for blocking external noises such as traffic and construction sounds. Its walls are available for public, private, and commercial use and have a sound-insulation value of up to 67 dB — which is comparable to a 50 cm thick concrete wall.

Each wall consists of a durable, galvanized steel sheet that — when filled with soil — gains a lot of mass used to block and absorb noise. The system can be planted with local and typical plants as well as usual garden plants, and even vegetables are also possible.

According to Naturawall, the main requirement for these walls is to have leveled ground. Then, after the installation, a species-rich biotope develops within a short time — offering absorption of noise, wind, and dirt. In fact, Naturawall effectively doubles as a new habitat for birds, bees, butterflies, lizards, and other living beings.

Also worth noting is that Naturawalls are recyclable, require up to 80% less space than a conventional wall, and do not require expensive investments in foundations and ground anchoring. What’s more, these are some solid constructions that are said to be resistant to extreme weather conditions, giving them a long lifespan.

In addition to building the walls, the company also offers advice to its prospecting customers on plant selection, positions of the wall, and more.


Germany-based Naturawall has developed nature-friendly, plant-covered steel barriers that block noise.

Requiring less material than traditional concrete walls, Naturawalls provide protection from sound pollution and additional habitats for animals and insects. The barriers are available for public, private, and commercial use, and the company provides guidance on planting hardy, native plant species.

The barriers require a flattened area of ground and are then filled with soil. Plants can be added over time, and customizable features make the walls easy to adapt to a variety of locations and sizes.

And, should a wall no longer be needed, the steel it is made from is recyclable.

Action point

If your municipality is dealing with noise pollution, you may want to contact Naturawall and see whether they can help you tackle the issue. They will not only help you with that problem but will also add some biodiversity to the area — effectively providing habitats for animals and insects. They have already managed to install a few of these walls, and your city/town could be next on their list. You just have to contact them.

Chances are Naturawall is looking for partners in other parts of the world or even in parts of Germany where they have yet to install a single barrier. Exploring a potential partnership with them could potentially give you access to their expertise, and you can then sell Naturawalls to the municipalities your company works with. Or those you want to work with. With noise pollution raging on, there is definitely the need for these kinds of products all across the world.
