144 3 Life Cycle Inventory Analysis
Material/product Data basis
Raw carton For the modelling of the raw carton production four site-specific data
production records of the companies Stora Enso, Assi Dom¨ an, and Korsn¨ as are
consulted. They represent production at three Swedish and one Finnish
location in the year 2002. The data procurement took place in the
framework of an earlier LCA on behalf the FKN IFEU (2004). From the
available data an average value for the raw cardboard production is
formed, used for all examined beverage carton types
For the calculation of the expenditure for the wood supply informa-
a
tion from UBA, 2000a : Material Volume I; Industrial Wood (forest
NORTH) 1 is consulted. The data cover forest management, including
logging and transport of wood
The transport of raw carton to the composite production in Germany
is likewise considered
Aluminium For the production of cardboard composite material exclusively pri-
foil mary aluminium is used. The basis of the consulted LCA data is
production provided by ecoprofiles which were published in the year 2000 by the
European Aluminium Association (EAA), Brussels EAA (2000)
The data record for primary aluminium covers the production of
aluminium on the basis of bauxite extraction, aluminium oxide and
aluminium production (aluminium ingots) including anode produc-
tion and electrolysis. The data are based on collections of the European
Aluminium Association (EAA) in the years 1995 and 1998. A represen-
tativeness of 92% respective 98% of the European primary aluminium
production was obtained
The data record, according to EAA, was partly updated on the basis of
an survey of member firms in the year 2002. This updated data record
was provided European Aluminium Association (2006) by the EAA for
the use in LCAs. Statements concerning the representativeness of the
updated data are not yet available
The data records for aluminium foils are likewise based on collections
of the Association in the year 1998 for the production of semi-finished
aluminium. Depending on the product group representativeness between
20 and 70% was obtained
LDPE LDPE is manufactured in a high pressure process and contains a high
production number of long sidechains
The data record covers production of LDPE granulates starting with
the extraction of raw materials from deposits including associated
processes. The data refer to a period around 1999. They were procured
from a total of 27 polymerisation plants. The plants considered cover an
annual production of 4 480 000 tons. The European total production
in 1999 was approx. 4 790 000 tons. The data thus represent 93.5% of
Western European LDPE production PlasticsEurope (2005a)
HDPE HDPE is manufactured in different low pressure processes and con-
production tains less side chains than the LDPE
