50 TPH Throughput for RDF Now Being Achieved by MPS Betriebsführungs : UNTHA Squeezes its XR Ripper Waste Shredder into Tight Spot at MRF in Berlin
Austrian shredding equipment manufacturer, UNTHA, has delivered and installed its XR Ripper shredder at a complex project to overhaul an existing waste processing facility in Berlin.
According to UNTHA, MPS Betriebsführungs GmbH is no stranger to mechanical-physical stabilisation – a treatment method to obtain Refuse Derived Fuel (RDF) from residual waste. In fact, MPS’s plant has been operating in the north west of the capital city since 2005, and now processes around 180,000 tonnes of household and commercial waste each year.
However, with such significant volumes of materials to handle, MPS needed a shredder which promised higher system availability, throughput performance and maintenance simplicity.
The search for an alternative solution brought the team to UNTHA, but the configuration of the site meant that the installation would be far from straightforward.
“When MPS first started talking to us, one important prerequisite was that we could accommodate the structural parameters of the project,” explained UNTHA’s sales manager Daniel Wresnik. “The building had been constructed around the original facility which posed extreme limitations in terms of access and assembly.
“Following trials to prove the operational capabilities of the XR, attention therefore turned to the logistical elements of the project. Thankfully the compact and modular nature of the machine meant this wasn’t as tricky as it could have been. We delivered the shredder part-assembled, to enable fast commissioning, with the water cooling system and control cabinet integrated into one pre-fabricated auxiliary unit that simply needed to be positioned outside the hall,” continued Wresnik.
Thanks to careful planning to minimise the disruption to MPS’s hectic waste processing schedule, the old rotary shear was removed and UNTHA’s new XR installed within four days.
The XR3000R now acts as both a pre-shredder and a one-stage crushing solution. The machine is uniformly fed with waste by two conveyors, and an in-built pressure valve ensures continuous material loading.
With moderate filling, the process is said to be able to achieve throughputs of 50 tonnes per hour with particle sizing of less than 200mm.
Commenting on the research and selection process for this new machine, plant manager Markus Frank said: “In view of the required installation situation, the compact design of the XR was a decisive factor for us. Moreover, we were impressed by its high throughput performance, with a constant particle size guaranteed over the entire wear period.
“The XR also enables a targeted improvement in maintenance and upkeep, and guarantees the required high system availability,” he added.
As part of the project, UNTHA engineers visit the site on a monthly basis to train and support local staff, as well as auditing the maintenance works carried out since the last inspection.
“The low power consumption in combination with the low wear costs makes this machine simply unbeatable compared to those offered by other vendors,” concluded Frank.

UNTHA Shredders Online at Korean SRF Waste to Fuel Facility
South Korean waste management firm, Zion, has begun operations at its new Solid Recovered Fuel (SRF) production facility in Wonju city, which will supply fuel for the cement industry.
UNTHA Shredders for SITA's New SRF Plant in Birmingham, UK
UNTHA has installed three high-specification shredders at SITA UK's new 60,000 tonne per year Solid Recovered Fuel (SRF) plant being in Birmingham.
Solid Recovered Fuel is still classified as a waste material, not a product, despite the fact it is manufactured to a quality specification and is a resource from which energy can be recovered. Marcus Brew, UNTHA UK's alternative fuels expert, considers the parameters within which SRF must be manufactured and discusses the arguments for and against SRF being reclassified as a product or fuel?
