『Abstract
This paper presents and discusses the method and results of account
for material flows in Sweden for the year 2004. The results show
that it is possible to compile material flow data from existing
sources in the Swedish statistical system. By using the European
classification system of goods, the Combined Nomenclature, as
the basic unit of the data collection, both data collection and
aggregation into material flow categories were made possible.
Although these data exist in the statistical system, they are
not easily available for the scientific community. This is due
to several reasons, such as the aggregation of data in the system
of statistics not corresponding to the material flow account structure
and the fact that data on import and export of materials are organised
differently than data for domestic extraction. Almost 50%of the
material flows in Sweden are flows of minerals, mainly construction
minerals followed by iron ores. Most of the extracted iron ores
are exported. In comparison with other European countries this
generates a unique situation with Sweden as the only net exporter
of iron ores. The flow of biomass in terms of wood is also considerable
(26% of the Swedish material flows in 2004). The domestic material
consumption (inflow) per capita in 2004 was 8 tonnes minerals,
6 tonnes biomass and almost 3 tonnes of fossil fuels. Of the material
flows of fossil fuels petroleum and natural gas dominates with
90%.
