A high throughput, low maintenance machine

At UNTHA, we believe in solving clients’ problems

So, when it came to engineering a next-generation biomass / waste wood shredder capable of processing up to 30m³ per hour, we spoke to operators around the world to support our research and development.


The result of this collaboration is a feat of engineering that delivers some of the industry’s highest throughputs, with the lowest maintenance efforts. The single-shaft machine can produce high-quality fraction for wood chip, biomass or briquetting, but ease-of-configurability guarantees maximum application flexibility for this challenging business environment.


The goal was to achieve trouble-free waste wood shredding, recycling and biomass production…


So here’s the answer – the QR.
