Table 15.8 shows the boiler fuel consumption for auxiliary equipment in
tankers [ 40 ].
Air-conditioning requires a performance of approximately 5.0-10.0 W (6.8-
13.6) 9 10 -3 HP per 1.00 kW (1.36 HP) of the main engine power on an average
merchant vessel. With the increase in average air temperature because of climate
change, also the costs of air-conditioning and perishable goods' cooling in shipping
will increase [ 41 ].

15.6 Recycling and Climate Balance of Transportation

Recycling has a growing meaning in environmental technology. Today, an
increasing number of people want vehicles, airplanes and ships which meet the
highest environmental standards, including recycling. People require batteries
which do not have heavy metals, coolants which are biologically degradable,
construction which can be recycled and energy recovery systems which use the
stored braking energy.

15.6.1 Recycling of Vehicles

In accordance with legislation, all parts of road vehicles, airplanes, and ships have
to be recyclable by up to 90-95%. Besides traditional materials for building
