6.5.1.3 Defining the process map of product ’s life
cycle
The scope of this streamlined carbon footprint was from
‘cradle to gate’, which included the life cycle stages related
to the plastic removal, transport, treatment of the
removed plastic and the disposal of the residue (refer to
Figure 6.8). These stages are summarized below:
Pass ive cleanup of the ocean
Activities of The Ocean Cleanup Array to remove plastic
waste out of the ocean.
Load ing/Transshipment
Charging of the vessel which transports the plastic to
land.
Marine transport
Fully laden vessel sails from The Ocean Cleanup Array to
land.
Discharge/Transshipment
Offloading the cargo from the vessel.
Pyrolysis
The end-of-life plastic is transformed into oil and residue.
Disposal
Transport to dispose the residue.
No transport was taken into account after the discharge
of the vessel as the pyrolysis plant was assumed to be
situated in the port of arrival of the vessel.
