stream. It relies on a subtle dispersion of
micro-drops – comparable to mist. This means
the scrap stays largely dry and that the quality
of the fractions is not compromised. ‘As such,
Jet-Zone does not affect sorting performance,’
Savic underlines. ‘Once recyclers understood
that, they got on board with our technology.’
HOW MANY INJECTORS?
Operators can choose which injectors are acti-
vated for specific tasks and how much mist is
released in any required direction. ‘In the sum-
mer, when the material is dry, you can program
the system to release more micro-drops than
during cold, damp seasons,’ the businessman
points out. ‘In the winter, you’ll probably need
five times fewer micro-drops than when it’s
warmer.’
Companies can opt for either two or up to 12
injectors. Four and six are the most common in
Europe, depending on the size of the shred-
der, because recycling lines usually feature
overhead dust extraction systems. ‘Our solu-
tion is a great addition to that, catching even
fine dust particles inside the shredder as well
as along the complete shredder line,’ Malfait
explains.
‘In the US, however, most recyclers won’t have
far-reaching dust cleaning systems. So
American and Canadian recyclers prefer a
more elaborate Jet-Zone system with eight or
more jets. We’ve installed systems with up to
12.’ Savic adds: ‘We’ve also expanded our cus-
tomer network to include recyclers worldwide.’
MANAGING RISK
‘Besides witnessing spectacular dust suppres-
sion results, our clients confirm that the Jet-
Zone system helps reduce blue smoke while
also reducing explosions – both in number and
intensity.’
A Swiss client of Jet-Zone, with a facility close
to a city centre, is a good example. ‘They used
to experience up to 30 explosions each year
but now we’ve brought it down to seven,’
Malfait states. ‘Hitting zero is virtually impossi-
ble because it depends on external factors
such as input volume, material type, equip-
ment maintenance and so on.’ With a laugh,
the businessman adds, ‘We can’t do magic
but, yes, our installation can have a meaningful
impact on dust emission and safety.’
Galloo has been very pleased with its partner-
ship. ‘At Galloo, we are constantly looking for
new solutions to boost our recycling practices,’
says company ceo Rick Debaere. ‘This enables
us to notably reduce emissions of certain
crushes way beyond current industry targets.
The Jet-Zone technology practically sold itself
because we received such positive feedback
from the operators and site managers.’ Kevin
Casier, Galloo’s technical manager, praises the
how project follow-up, saying it was ‘very pro-
fessional and flexible’ from start to finish.
WHAT DOES JET-ZONE DO?
Speciality: Dust suppression systems
Invented by: Mirko Savic and Nicolas Malfait
Produced by: Jet-Zone’s parent company Savic Group
Purpose: Keeping the shredder line clean and safe
How does it work: A series of (or individual) Jet-Zone injectors inject a mist of micro
droplets into the shredder housing. The system releases over 15 million droplets per
litre of water. The waste stream remains dry while this approach covers 20x the sur-
face area when compared to traditional water based systems.
Results: up to 80% less diffuse dust emission at the entire shredder line; up to 30%
less emission at the shredder dedusting chimney; and less blue smoke.
Safety perks: Jet-Zone delivers a notable drop in the amount of explosions on-site.
Models available: Indoor (cabinet) and outdoor (container)
