Direct collection of the available input and output data through
the use of the collected materials. In this way, it was possible to
obtain activity data on: energetic consumption, raw materials
consumption, auxiliary and technical materials, direct emissions
into the atmosphere, wastes produced during production
and the destination data of the beverage carton material after
usage. For the processes of transport and disposal/recovery of
wastes directly produced from different establishments, data
were required from different suppliers. The end of life data
were furnished by COMIECO, the Italian consortium dealing
with the collection of cellulose packaging.
Data from previous studies on transport: for the overall
transportation we considered the results of a study that was
concluded in 2004 relating to Tetra Pak in Italy.
