UNTHA XR3000C mobil-e shredder




The first UNTHA XR shredder is now operational in Melbourne, Australia, following a 15,000km journey from the world-renowned engineering facility where it was manufactured in Austria.

The 37-tonne mobile machine arrived July 2019 at Knox Recycling (KTS) – a long-standing client of FOCUS enviro. Since then the UNTHA XR3000C mobil-e has been handling up to 30 tonnes of commercial, industrial and wood waste per hour, to manufacture PEF.

Previously unable to produce this high-specification fuel with only one machine, the Knox team accompanied FOCUS enviro on several site visits across Europe, to see the UNTHA shredder in action. Impressed by the single pass shredding capabilities of this robust technology, FOCUS enviro then set about configuring a solution that could achieve Knox’s refined output particle requirements, with ease.

Project Highlights

Key outcomes and benefits of the project

UNTHA XR 3000 mobil-e takes advantage of an electromechanical drive without forgoing the advantages of a mobile machine

Consistent 30mm to 400 mm particle sizes are achievable

Ability to produce a homegenous and defined output fraction in a single - more opportunities for difficult to shred applications

This shredder is ideal for thermoplastics, duroplastics and elastomers due to its range of shaft and cutter configurations

UNTHA are specialists in plastic granulation, tyre-derived fuel, mattress, biomass, pulper ropes and e-waste resource recovery markets - and offer ideal solution for KTS

The shredder is also ideal for the growing gasification and biomass markets in Australia

KTS Recycling is leading the way in RDF

At the time of the installation, FOCUS Enviro commented to the media: “We have seen what the XR mobil-e is capable of, as it has continued to transform the throughputs, fuel quality and energy efficiency of facilities worldwide. We’ve therefore worked hard to bring this pioneering UNTHA innovation to Australia, so that it can start to revolutionise the alternative fuel production market here.

“No other machine can produce such a homogenous fuel in a single pass, so I think the Knox operation is going to be a leading light in Australia, when it comes to this fast-growing future resource market.”

What is ahead for alternative fuel production

Mark Jeffs, owner of Knox, added: “Alternative fuel production is becoming more and more important in Australia, and as a progressive environmental company we want to be ahead of the curve.

“We acknowledged that by investing in world class PEF production technology, we could produce a high-quality resource, efficiently, and hopefully really drive the market for this crucial energy source.”

What Our Clients Say

Don't just take our word for it
  • “The early results of the performance of the UNTHA XR have been very positive, and we have been able to trial new materials such as car and truck tyres. For example, this has already reduced disposal and transport costs, allowing us to send pre-shredded tyres to an end user.

    The big picture is to understand where our waste stream is currently sitting, to allow us to explore options for new residuals. The whole process has definitely been a learning curve, however we have come along way from when we started.”
