3.1 To achieve cost-effective and environmentally
sound results, many garbage management planners use a combination
of complementary techniques to manage garbage, such as the following:
-
.1 reduction at source;
-
.2 reusing or recycling;
-
.3 onboard processing (treatment);
-
.4 discharge into the sea in those limited situations
where it is permitted; and
-
.5 discharge to a port reception facility.
3.2 When requisitioning stores and provisions,
shipping companies should encourage their suppliers to remove, reduce,
all packaging, at an early stage, to limit the generation of garbage
on board ships.
3.3 When garbage is generated aboard a ship, procedures
should be defined to enable the crew to sort the material that can
be reused onboard the ship or recycled at an appropriate port reception
facility.
3.4 Ship's garbage is made up of distinct components,
some of which are regulated in MARPOL Annex V, while others may be
regulated locally, nationally or regionally. Each component of the
garbage should be evaluated separately to determine the best management
practice for that type of garbage.
