Waste wood and pallets

A sustainable resource. A wealth of opportunity

The intelligent re-use of wood is not a new phenomenon – as one of the world’s oldest materials, this sustainable resource has been recycled and/or repurposed for thousands of years. But the global wood processing landscape continues to change extensively.

In the UK, the Wood Recyclers Association has calculated that approximately 2.8 million tonnes (60%) of the country’s waste wood is being recycled – and that figure is expected to rise. In Austria, the forestry and wood processing industries are important elements of the country’s economy – in fact, biomass is widely regarded as the most important renewable energy source, with the nation’s ratio for biomass production/utilisation way above average.


But wood shredding, recycling and biomass production isn’t always trouble-free. Until now...

  • Why shred wood?

    Surplus, redundant and/or ‘waste’ wood can be salvaged and transformed into a variety of high-value resources including wood chip, biomass and briquettes.

  • Why shred wood?

    By harnessing the resource potential of wood, ‘waste’ disposal costs (including those associated with fines) can be avoided – in fact wood shredding is often rich with revenue generating potential.

  • How can UNTHA help you shred wood?

    Your shredding specification is our priority, from a defined G30 or P100 biomass specification, through to shavings for pet bedding! Talk to us about our quick-change cutter system.

  • How can UNTHA help you shred wood?

    Depending on the material type/output specification, we can achieve throughputs of up to 45 tonnes per hour, with a high-grade P63 specification in a single pass. By investing in only one machine, that means half the capital expenditure of a dual-process line, and a far quicker payback period.

  • How can UNTHA help you shred wood?

    We don’t just evaluate waste shredding performance in terms of throughputs – we also pride ourselves on our technology’s ability to achieve on-specification particle sizing, low fines, reduced fire risk, 60 % better energy efficiency, low maintenance, impressive uptime, low noise, robust safety mechanisms and maximum margins. All of this with up to 80% increased yield on ferrous and non-ferrous material, which could pay for the machine in as little as 12 months!

What waste wood can we shred?

Our range of waste wood shredders

  • This world-renowned machine has changed the face of biomass shredding, promising defined fraction sizing, low maintenance and uninterrupted shredding with minimum fuss.

  • Popular with operators who prefer to alternate the location of their unit, from a fire safety and insurance perspective. Also easy to move around a site to handle different wood streams.

  • A maintenance-free machine with pusher technology for maximum yield and uptime when processing up to 30m³ per hour.

  • The ideal compact shredder for low volume biomass production, capable of handling 12m³ of wood per hour.

Crapper & Sons

“We’re now manufacturing a higher quality, on-specification biomass fuel, with only one shredder not two, and we’re benefitting from 20% more uptime. We’re also getting about 18 tonnes of clean metal a week from 1000 tonnes of wood waste, which we can now sell. The XR’s low noise and reduced energy consumption of course add to the benefits of the shredder, and its low dust, slower speed electric drive makes our woodyard a far safer place.”
