New system for dealing with confidential waste brings a trio of benefits to
Derby Hospital’s NHS Foundation Trust
UNTHA UK, Veolia Environmental Services and Kelpack helped Derby Hospital’s NHS Foundation
Trust achieve significant security, cost and environmental improvements, following investment by
the Trust in a new confidential waste management system.
Confidential hospital waste which was previously transported and incinerated off-site to create
energy from waste, is now being shredded and recycled in a move which is improving the hospital’s
carbon footprint.
Simon Marriott, project manager for Skanska, the hospital’s hard facilities management provider,
explained: “Our ongoing aim is to improve the recycling performance of the Trust and divert as much
waste away from landfill and incineration as possible.
“We knew that shredding and recycling our confidential waste would improve our environmental
performance so we asked our waste and recycling partner Veolia Environmental Services to help us
find the best solution. Veolia Environmental Services approached their first-tier supplier Kelpack,
which in turn led to a partnership with UNTHA UK and the development of a completely new
UNTHA UK visited the hospital to fully understand and audit the client’s needs. Subsequent
consultations and system appraisals led to the development of a one-off complete solution, with the
UNTHA RS30 shredder being recommended in conjunction with Kelpack’s 200 model compactor.
The RS30 set the recycling industry alight over 25 years ago when it was introduced as the world’s
first four-shaft shredder. Now the 21st century machine has numerous cutter and screen variants
which can be individually configured to meet specific client requirements, and the machine’s low
cutter rotation speed ensures a very quiet shredding process.
UNTHA UK managing director Chris Oldfield said: “Data protection has never been so important.
Hospitals are required to comply with the European standard for paper shredder security and must
achieve a minimum of DIN level 3. We have strong expertise in the management of clinical waste
and were able to recommend and implement the best solution for the hospital to ensure that they
met their DIN level obligations. With holes of less than 25mm diameter the UNTHA RS30 shreds
items into small confetti-like particles which when combined with the mixing action ensures utmost
Derby Hospital’s shredded waste now feeds automatically into the Kelpack 200 model compactor
which was chosen for its speed and ability to compact to very small volumes. The compacted waste
is then taken by Veolia Environmental
Services for recycling in the West Midlands
before going to a paper mill for re-pulping.
Following the integration of the new
shredder and compactor, Skanska and the
hospital have seen a number of benefits.
Simon Marriott explained: “We are
delighted with the integrated system. All
confidential paper is retained within a
specially designed portcullis door
developed by Veolia – and when the waste
leaves the site it is completely illegible.
We’ve eliminated the need to store the waste and we are seeing cost savings of 30-35% as we
receive a rebate from the paper mill of around £15 per tonne.
“The environmental benefits are also clear to see. Vehicle loads have been reduced as the
compacted waste takes up approximately 85% less space. In addition the vehicles no longer have to
travel further distances to the incinerator. And as we’ve replaced incineration with recycling, we’re
moving up the waste hierarchy and improving our carbon footprint.”
UNTHA UK and Kelpack support the hospital with a fully-inclusive maintenance and service package.
Selected hospital staff have been trained to use the shredder with access only available via a secure
key code.
