UNTHA UK expands shredding portfolio to help operators tackle complex materials, cut costs, and improve fuel quality
As waste processors face growing pressure to handle more complex material streams, improve fuel quality, and control operating costs, UNTHA UK is broadening its shredder portfolio with the launch of brand-new machines – the MR1800C Pro universal shredder and the SR2000XC and SR3000XC secondary shredders – alongside a suite of next-generation developments to its existing technology. These innovations will be showcased by UNTHA GmbH at IFAT Munich 2026.
The MR1800C Pro addresses a longstanding gap in the market: materials that are simply too tough or too varied for conventional shredders. This machine will enable hard plastics, production waste, compressed film bales, and waste wood to be processed in a single pass at throughputs of up to eight tonnes per hour.
For operators that have previously had to reject difficult materials or run them through multiple stages, this opens up waste streams that were previously deemed uneconomical to process. Both the number of knife rows and individual knives can be adapted precisely to the material being processed, while fourfold reusable, clamped rotor knives can be quickly replaced and multi-use, adjustable cutting bars extend service life and minimise wear-related costs.
Meanwhile, for alternative fuel producers, the new SR class – comprising the SR2000XC and SR3000XC – tackles the quality and consistency challenge head on. With a one-metre rotor diameter and a drive power of up to 2 x 250 kW, it delivers a fine, homogenous output suitable for producing high-quality substitute fuels like RDF – helping operators meet increasingly stringent specifications while improving productivity and lowering operating costs. A beltless power drive with a maintenance-free safety clutch also removes common wear points, reducing both planned downtime and unexpected maintenance challenges.
Additionally, UNTHA’s established XR mobil-e is also receiving an upgrade, now available with asynchronous drive technology for heavy-duty applications. With multiple cutting configurations, both stationary and semi-mobile options, and the ability to handle everything from waste wood and bulky waste to tyres and pulper ropes, the XR continues to offer operators flexibility across diverse material streams.
UNTHA UK is also relaunching its advanced generation RS Series 4 class of four-shaft shredders. Spanning the RS30 through to the RS150, this is the firm’s precision line-up for industrial recycling – used to tackle highly complex waste streams including WEEE, confidential waste, metal swarf, plastics, tyres, bulky household appliances, and hazardous waste.
The RS range has been comprehensively redesigned with several major innovations built in to help meet key industry challenges, including remote diagnostics with SMS alerts, upgraded mechanical sealing designed to extend service intervals, new IE3 motors, and a refreshed exterior with LED status lighting.
Marcus Brew, managing director of UNTHA UK, comments: “We’re seeing customers face increasingly complex waste streams, tighter fuel specifications, and real pressure on operating margins. The new MR and SR machines directly address those challenges.
“And for any business shredding or recycling for secure destruction, the RS Series 4 upgrades translate into something very tangible: less downtime, lower energy bills, and longer intervals between servicing. When you look at the total cost of ownership – reliability, throughput, and reduced maintenance over the machine’s lifetime – we’re confident it’s the strongest package on the market.”
Stefan Scheiflinger-Ehrenwerth, chief innovation officer at UNTHA, adds: “Our developments represent a real technological leap forward. We solve shredding problems that were previously considered difficult to implement or uneconomical. With our new shredders, we enable customers worldwide to process even the most demanding materials quickly and efficiently, thus creating new value-added potential."
UNTHA will be exhibiting at IFAT Munich 2026 in Hall B6, Stand 127, with live demonstrations of the XR3000RC powered by the UNTHA Power Core on the VDMA outdoor grounds.
