Spross doubled its robot count for efficient and effortless recycling


Swiss-based family business Spross AG has reinvested into ZenRobotics robot technologies to recover more valuable fractions at their Spross Recyclingwerk Zurich RWZ site. The facility processes 180,000 tonnes of construction waste and bulky household waste annually. Spross recycles waste by sorting it and sending it to different recovery facilities in Switzerland where the waste can be reused.

Robots have increased work safety by replacing manual labor.

Sorting more fractions at the speed of up to 4000 picks per hour


Spross began its cooperation with Zenrobotics back in 2019 with an aim to increase the efficiency of their waste recycling. Manager of Disposal Services at Spross-Groupe Josef Binzegger has been more than happy with the waste sorting technology Zenrobotics provides.

So much so that the waste operator has now decided to invest more into ZenRobotics’ technology. Spross will double the amount of Heavy Picker robot arms at their RWZ facility in 2022 to have more fractions sorted at up to 4000 picks per hour – allowing them to earn more from valuable fractions or reduce the cost of elimination. So far, the robot’s been recovering mainly concrete and stone for concrete production, and also wood and plastics as well as some metals.

"We are working 13 meters above ground and what amazed me was that these robots work perfectly in these difficult surroundings. This environment is dusty, it is not heated and the ground vibrates all the time."

Josef Binzegger,
Manager of Disposal Services at Spross-Groupe.

The waste sorting robot is reliable even in challenging conditions


The robot is custom made and it is a perfect fit for the plant despite its challenging environment.

Because the waste sorting robots work so well under challenging circumstances, they have increased work safety by replacing manual labor. Thanks to the robot’s high-performance and reliability, people have been able to increase their own production.

Easy to operate and functional


Binzegger is astonished by how well the robot can differentiate between various kinds of materials with a single arm. The waste sorting robot can sort up to four different types of fractions and can be programmed to detect new sorts of waste simply by running the waste through it and telling the robot that this item needs to be collected.

Zenrobotics allows Spross to keep up with legal and commercial requirements and is able to adapt to waste regulation changes with ease. The waste sorting robot is also very easy to use via a touch screen.
