Which types of residual timber can be shredded?
Off cutts

Shredding cap timber or off cuts is quite a challenge for wood grinders. The machine needs to be particularly robust and sturdy. We offer shredding solutions specifically designed for this "very hard" application.


Specific characteristics and solutions

Through the generation of a homogeneous granulate from residual timber, an economically-viable secondary fuel can be obtained. This is then used, for example, in the following areas:

  • Company wood chip firing applications

  • Biogas plants and co-generation plants

  • Manufacture of wood briquettes

We offer a large selection of single-shaft and four-shaft shredders with various working widths, rotor diameters and drive capacities for your residual timber. The possible granulate sizes usually range from 12 to 80 mm. Regardless of whether you need a compact system or a particularly high-performance individual wood shredder – we will always have a suitable solution available.

Our range of offers is rounded off with the ideal accessories, whether conveyor screws, conveyor belts or a system for extraction. We align machines and accessories optimally with each other. At UNTHA, not only do you benefit from the perfect system solution – you also receive a 3-year warranty on all wood shredders.

From the initial planning phase, through project planning and on to commissioning, including all necessary peripheral equipment, we offer our customers everything from a single source. We also take care of the electrical integration of control systems into existing installations, along with the respective conveyor systems. We provide complete solutions for wood-working and wood-processing enterprises.

Pallets and wood packaging are an essential component in the transportation and storage of stackable goods as well as heavy and valuable objects.

Bulky waste

Bulky waste contains many different and valuable resources which can be recovered and reintroduced into the raw material cycle through good material preparation and the correct system technology.

Commercial & industrial waste

Commercial and industrial waste is collected separately according to the respective components before being processed and reintroduced into the raw material cycle (recycling), or recovered for thermal recycling or for energetic utilisation (substitute fuels).

Pulper ropes

Pulper ropesaccumulate during the production of paper - or, more precisely, during the recycling of waste paper. Half of these so-called rejects generally consist of metal, which is why their processing is particularly arduous and challenging.
