| Saving
fuel and reducing emissions
Jochen Deerberg
Owner and Chief Excutive Officer
Deerberg-Systems
As the world’s
leading supplier of state-of-the-art environmental protection
systems for ships (including more than 150 cruise vessels and
26 Superyachts), Deerberg-Systems has become renowned for innovation
particularly in the area of waste management.
Our latest
breakthrough product is the Deerberg Integrated Biowaste Dryer.
Installing four of these on a 5,500-passenger ship with two 2,400kW
incinerators deliver annual savings of about $350,000 because
it reduces diesel oil use by 620 tons. In turn, this reduces CO2
emissions by about 7,500 tons a year.
It is designed
to handle the biosludge from advanced waste water treatment (AWT)
plants as well as food and wet waste from the hotel department.
It allows
the operator to process the waste onboard, independently of receiving
stations and will play an essential part in supporting a “zero
discharge” policy as the amounts of biowaste have multiplied
as ships have increased in size and capacity.
The new dryer
is the result of more than 20 years’ expertise in food/wet
waste handling and processing (Deerberg-Systems was founded in
1982) and followed our introduction of the first AWT interface
in 2003, which steam-dried the biowaste prior to it being fed
into the incinerator.
This was a
breakthrough in its own right but the process still required the
use of additional energy so our research and development department
was tasked with developing a dryer which - instead - used the
energy already created by the incineration system itself.
This required
another major breakthrough in energy recovery technology which
R&D again delivered.
After evaluations
and modelling in conjunction with the Alfred Wegener Institute
in Bremerhaven, pilot tests were carried out in Papenburg and
the dryer was approved by Lloyds Register EMEA.
The Deerberg
Integrated Biowaste Dryers are already being installed on two
cruise ships.
