The amount of waste landed at each port and its subsequent disposal route is influenced by the waste
generation location as well as the availability of waste contractors and disposal facilities near the port. Just over
192,500 tonnes (88 per cent) of the total waste returned to shore landed in the north east of Scotland at ports in
Aberdeen and Peterhead. Of this, 81,000 tonnes (42 per cent) were sent to landfill for disposal, while 33 per cent
(63,000 tonnes) was designated as “other” for disposal routes such as treatment of aqueous wastes, composting
and land spreading. Almost 46,000 tonnes (24 per cent) were reused or recycled.
3.6 Fluorinated Gases
Fluorinated gases (F-gases) are used for industrial applications such as refrigeration, air conditioning and to a lesser
extent fire protection systems and electrical switch gears. They are a known GHG and contribute towards global
warming and, as such, their use is regulated under the 2014 EU Fluorinated Greenhouse Gas Regulation as part of
the Kyoto Protocol
45
. The Regulation impacts anyone who manufactures, uses or services equipment that contains
F-gases, like refrigeration, air conditioning systems, solvents or aerosols and is therefore applicable to the offshore
oil and gas industry. Regulated F-gases include HFCs, PFCs and other perfluorinated compounds including SF
6
.
Figure 18 overleaf shows that improved reporting from offshore installations led to an increase in the CO
2
e
emissions of HFCs between 2010 and 2015, with the number of platforms reporting each year rising from 117 in
2010 to 222 in 2015. This reflects the importance that industry places on managing the use of F-gases. Eliminating
the use of chlorofluorocarbons (CFCs) due to their environmental impact may also have led to an increase in the
use of HFCs as suitable replacements.
