Thanks to the new ‘Cradle-to-Cradle Passport’, Maersk Line will be better able to recycle parts and materials used in the construction of the vessel.
The passport, which will be updated throughout the life of the ship, is a database listing the material composition of the main parts of the ship. Cradle- to-cradle refers to the optimum lifecycle of the materials used in a product.
Recycling in shipping is important as the industry is dependent on many re¬sources, but two stands out as critical: the steel used to build ships and the oil used to produce the fuels we use. Both of these resources are finite. In order to stay in business in the long run we need to find ways to im¬prove resource efficiency while looking for potential alternatives.
Steel is being recycled on a large scale today; however, different types of steel and metals are often mixed in the recy¬cling process. This reduces the quality of the recycled steel, thus sustaining the need for the resource-intensive mining of new iron ore.
Together with the Korean shipyard DSME we have started to address this issue through a ‘Cradle-to-Cra¬dle Passport’ which will be implement¬ed on the new Triple-E ships. The pass¬ports will document approximately 95% (by weight) of the materials used to build the ships, thereby enabling better recycling of parts and materials used in the construction of the vessels.
This project requires the continuing ac¬tive involvement of approximately 75 suppliers of parts to the ship. Our experience will be shared with our partners in the Sustainable Shipping Ini¬tiative with the aim of broader applica¬tion of this type of ‘closed-loop’ material management in the shipping industry.
