How to securely shred confidential waste paper

Did you know that, with UNTHA’s four shaft shredders, your confidential waste is in extremely safe hands?

So much so, our RS30 and RS40 confidential waste shredders have been independently tested and certified as conforming to security levels P3 and P4 for sensitive documents, O3 for data destruction and H5 for hard drives.

These four shaft shredders were rigorously audited in Austria, when external organisation DEKRA Certification GmbH trialled the technology using different confidential waste input materials and various screens.

Carried out under strict DIN 66399-2:2012 test conditions, the study found that these popular shredders could comprehensively achieve:

–          P3 (2mm strips or maximum particle surface of 320mm²) and P4 (maximum cross cut particle surface of 160mm² with a maximum strip width of 6mm) confetti cut shreds, required for sensitive and confidential paper-based information

–          O3 (a maximum shred of 160mm²) for optical media including CDs and DVDs

–          H5 (a maximum shred of 320mm²) for hard drives from computers, laptops and external devices.

The RS30 and RS40 shredders will hold this prestigious certification until 2019.

Commenting upon this accolade, UNTHA UK’s sales manager and confidential waste shredding expert Dan Fairest said: “We confidently recommend our four shaft shredders for even the toughest of confidential waste shredding scenarios, and have a number of models within the RS series, to cater for varied data and product destruction requirements.

“But our claims and belief in the shredders are not necessarily enough for organisations seeking utmost reassurance that their data protection obligations will be upheld. This certification now provides prospective clients with an absolute guarantee that, with UNTHA, their confidential waste is in safe hands.

“I also encourage organisations looking to invest in a confidential waste shredder for sensitive paper documents, hard drives, CDs and other secure products, to speak to our existing customers regarding their experiences. Better still, why not trial one of our RS shredders with your own materials, here at our North Yorkshire headquarters?”

Dan Fairest is currently penning an advice-led article regarding the best-practice shredding of confidential paper waste for industry journal Pulp, Paper & Logistics. Due to be published in the magazine in Summer, the feature will appear on the UNTHA UK website thereafter. Watch this space, or follow @UNTHAUK on Twitter to read this and other commentary.
