“Houston, we have a solution”
UNTHA shredding technology GmbH has been developing and producing reliable wood shredders for carpentry and joinery businesses, sawmills and the woodworking and wood processing industry since 1970. UNTHA's motto for LIGNA 2025 is “Houston, we have a solution”: In addition to its shredders, the Austrian company will also be showing corresponding conveyor technology and individual system solutions for the efficient recycling of waste wood.

At its stand (Hall 13 | Stand E18), UNTHA will be presenting, among other things, wood shredders from the LR and RS series: including the efficient 1-shaft shredders LR630, LR700 and LR1400 and a new product – the 4th generation 4-shaft shredder RS30. In addition, a part of the extensive conveyor technology range can be seen: spiral conveyor, conveyor belt and metal separator.
System solutions for recycling wood waste
“Our motto is 'Houston, we have a solution'. We want to show LIGNA visitors how our shredders can be integrated into their facilities – either as a stand-alone solution or as part of a complete system including all the necessary peripheral equipment, such as conveyor technology and magnetic separators,” says Josef Gruber, Head of Global Sales and Business Development BU Wood at UNTHA.
The wood shredders can be operated as stand-alone units or integrated into comprehensive system solutions. They can be flexibly placed in the company – in pits, in outdoor areas or near the production area – but can also be directly integrated into production lines and connected to other machines, as well as to extraction systems and silos, by means of conveyor technology. What is more, UNTHA shredders can be integrated into the control system of complete plants and can be equipped with additional safety features such as light barriers.
The Austrian premium manufacturer supports its customers throughout the entire process: “We value comprehensive customer care and support with advice, planning, design, installation and commissioning. And our service team is also always available to supply customers with spare parts, to support them with service and maintenance work and thus to maintain the longevity of the shredders,” Josef Gruber continues.
For decades, UNTHA has been inspiring customers worldwide with its sophisticated wood shredders. They are characterized by their robust construction, high throughput and reliable shredding of waste wood. The result is a homogenous wood chip that can be recycled directly. This enables companies to recycle waste wood in a meaningful way, reduce costs and improve their carbon footprint.
