Figure 8. Principle of dust suppression system.
Another way to manage dust problems and prevent dust concentration is mobile dust
suppression system (figure 8). Dust Suppression System uses high pressure water fogging
which creates an ultra-fine fog consisting of very fine water droplets (less than 10 micron
size) defined as dry fog in diameter. These tiny water droplets absorb even the smallest dust
particles in the air. It is particularly suited for dusty environments. Operating cost,
depending on the size of the system, can be as low as 20 cents an hour, water and electricity
combined (GreenPort, 2015). This type of system is mobile and could be used during cargo
handling processes in main points where dust concentration is in highest level (on ship deck,
near bulk cargo unloading stations and so on).
Conclusions
1. A green logistics conception implement through technological processes creates
assumptions to pay more attention to sustainable development. The main benefit of
green logistics conception and sustainable development is that through these ideas can
be minimized and reduced negative impact to urbanized areas, aquatic ecosystems,
which are bordered with seaports. Many technologies within the green logistics
concepts framework of modern seaport activity are classified as advanced or innovative
technologies; they change the approach to logistic process control. However,
application of innovative technologies in industrial processes, based on the legal
environment and environmental regulation is inevitable in perspective.
2. During last 12 years, the most handling cargo is bulk cargo (grains, bulk fertilizers, peas)
in port of Klaipeda. During bulk cargo handling processes large amounts of
environmentally harmful dust is released, which spreads in the port city of urbanized
areas, some of which falls through the primer and gets into the Curonian lagoon water.
3. After a look at the bulk cargo handling technological process, it was found out, that the
main points of dust concentration generation in the whole logistic chain are cargo
handling points: logistics business operational region (the point where cargo handlingtraveling
process starts and ends: manufactures, user of the product), second one in
the marine logistics area (includes such points as: cargo unloading points, conveyers,
warehouses, dry bulk cargo loading points where cargo is loaded onto ships and so on).
Exactly at these cargo handling points can be modernized technological processes,
implementing some new innovations such as dust suppression hoppers, telescoping
loading chute, dust suppression systems.
