Material/product Data basis

To the modelling of data for the production of pre-products naph-
tha, reformate gasoline, and p-xylene, a refinery model was applied,
developed at the IFEU institute, which reflects the technology used at
present in Europe
The data basis for the modelling of ethene production from natural
gas and naphtha are data available from the IFEU of various European
crackers in an almost representative distribution. The data originate from
the years 2000 and 2001
The data on ethyl glycol production characterise a cross section of
European plants, which refers to the years 1997–2000
The data on terephthalic acid production are based on data from Euro-
pean Plants, procured by Professor Rieckmann (FH Cologne) converted
by the IFEU according to the requirements of an ISO-conformal LCA and
used
The data record on PET production in bottle-grade is based on the
production capacity of five European plants and was arranged by
Professor Rieckmann (FH Cologne). The data refer to the period
2002/2003. Approximately 36% of the European PET production is
covered by the PET data record. In view of the differences concern-
ing selected plants and PET qualities a representative overview of
European bottle-PET- production can be concluded

3.7.2.2 Production by Materials

Material/product Data basis

Composite The main component of the beverage carton composite is the raw
cardboard carton. It is sealed by a layer of LDPE on the outside and inside.
production Depending on production printing takes place before or after this first
coating process. For longer durable products, like juice and ice tea,
additionally a thin aluminium foil is inserted on the inside for a
protection from light and oxygen. It is further separated from the
contents by a thin LDPE-layer
The data on the production of the composite were procured in the context of
a
an LCA on juice. They represent production at German Locations of the two
largest manufacturers in the period 2002/2003. These data allow a
differentiated view on individual composite types used for different
packaging volumes. In each case they contain data on energy and water
consumption, emissions, wastes, and packaging material for the
dispatch. According to information from the enterprises these data are
essentially also valid for the year of reference of this study
