Individual components and complete plants for the recycling industry

Volker HAAS, Managing Director of HAAS GmbH, was born in Stockum-Püschen in 1960. He and his three brothers (Armin, Martin and Harald) were born with the talent for mechanical engineering, so it is not surprising that all of them learned the craft of mechanical engineering.

In 1989 Volker Haas was faced with the question of how to continue his career. With a “bag full of ideas” and a “box full of tools” he decided to start his own business with stationary machines such as chippers, hammermills, screens and conveyors in the sawmill/wood industry sector.

It all started in a double garage in Stockum-Püschen. A hall with a basement office in Bad Marienberg quickly became the headquarter of “HAAS Holzzerkleinerungs- und Fördertechnik“. Martin Haas stood on his brother’s side from day one and spent every day in the workshop designing the first machines. In the first half of the first business year Armin Haas followed his two brothers and two other permanent employees now belonged to the HAAS team. Only a few months later in 1990 HAAS was converted into a limited liability company.

Until 1992 HAAS supplied individual components within Germany and throughout Europe. In 1992 HAAS produced the first complete plants for waste wood recycling. Company Schmid in Gussenstadt, one of the first HAAS major customers, still has its plant in operation today. Continuous plant extensions led to an increase in performance, today Schmid processes 50.000 tons of waste wood per year!

Also in 1992, the construction of the new company building in Dreisbach was started. Step by step the new building was extended, until a 3rd production hall was built in 2018.

The installation of a waste wood recycling plant with a throughput of 40 t/h, was the breakthrough of HAAS. The Bowie company in Tiel, the Netherlands, was already able to operate the plant at planned 50 t/h (no standard at this time). Conversion work with new conveying and screening technology was even able to increase the capacity to 60 t/h.

Since the end of the 1990s HAAS has also been producing and supplying machines for waste shredding and sorting.

Also Harald Haas decided to follow his brothers and has been active in our technical office ever sice.

In 1999 the TYRON – today’s flagship – was born at HAAS. The double-shaft primary shredder shreds waste wood, green waste, domestic waste, bulky waste or industrial waste and light metals. Over 500 TYRONS have already been sold worldwide!

Sascha Kloft took over the sales department at HAAS after his studies and pushed the HAAS mobile technology division. Since 2015 he has been supporting his stepfather Volker Haas as second managing director and will shape the future of HAAS GmbH positively.

In order to support the new line of business and the entire portfolio by name, the registered company name “HAAS Holzzerkleinerungs- und Fördertechnik” was supplemented with the registered trademark “HAAS Recycling-Systems”.

In 2018 the proven technology of the hammermill ARTHOS 1600 was presented at IFAT in a mobile version for the first time.
The mobile, electric TYRON hybrid and the new ALVA starscreen were presented at IFAT 2022.
In the future we will not get tired of continually working on the development of new innovations.
