Austrian Manufacturer Launches ‘World First’ Waste Shredder : New Mobile Electric Power Waste to SRF Shredder from UNTHA
Austrian shredding equipment manufacturer, UNTHA, has lunched a mobile, electrically powered version of its XR shredder – the ‘XR mobil-e’ .
The company said that the single step mobile SRF shredder provides customers with identical benefits – high throughputs, low operating costs, energy efficiency, low noise, foreign object protection and ease of maintenance as its static counterpart.
It is claimed to be the first machine of its kind to shred with a low power electric drive and, thanks to its on-board auxiliary power pack, it can be easily moved around a production facility and plugged back in.
Designed to provide flexibility, UNTHA said that the XR mobil-e can process a variety of materials including MSW, C&I, C&D, wood and other bulky wastes, to produce a wide number of high quality fuels for the waste to energy, cement, gasifier and biomass markets.
A series of interchangeable screens and cutters are said to enable the shredder to be configured according to the output specification, with homogenous particles of 30-400mm achievable.
According Peter Streinik, UNTHA’s head of business unit waste, when the company launched the XR in 2014, it received orders totalling 5 million EUR, but said that “the need for a robust, flexible and efficient mobile waste shredder was apparent”.
To address that demand the company began a nine month engineering project o research and develop the new waste shredding solution.
Trials in Austria, Germany and the UK were said to have revealed throughputs as high as 70 tonnes per hour, foreign object removal in minutes and machine reconfiguration to handle completely different material streams in as little as two hours.
“These trials enabled us to perfect elements of the technology prior to the market launch,” said Streinik. However, our European roadshow of events proved so successful, we are now quoting for dozens of alternative fuel production projects across the continent.”
The XR mobil-e is supplied on tracks with an adjustable exit conveyor and ferrous magnet to extract of valuable metals.
With low fines production, it creates minimal dust and combustible material during the shredding process. This combined with the slow-speed shredding concept and electro-mechanic – rather than diesel-hydraulic – drive, is said to considerably reduce fire risk and hence insurance premiums.
“Aside from the more obvious performance benefits, we’ve also received fantastic feedback about the emission-free, incredibly quiet operation of the XR mobil-e,” said Streinik.
“With noise levels as low as 80 dB(A) this protects operator wellbeing and ensures minimal disruption to neighbouring communities. It also facilitates extended operating hours which results in increased throughputs and plant profitability,” he continued.

Cement Kilns: A Ready Made Waste to Energy Solution?
ue to the nature of cement production, cement kilns require temperatures of 2000°C in their main burner. Excellent conditions for waste derived fuels, they have become a standard fuel for many cement kilns around the world. But there is potential for this to grow fivefold.
