3.2.2 Bulky municipal waste (bulky waste)
The trends in bulky waste volumes are illustrated in Figure 9. Until 1995, waste wood was collected
together with bulky waste. Introducing a separate collection of waste wood in 1996 reduced the bulky
waste volume which has been increasing continuously since 1991. Between 1996 and 2000 the bulky
waste volume amounted constantly to around 30 kg/inhabitant. After another increase in 2001 and
2002, it amounted to 39.4 kg/inhabitant (excl. waste wood) in the year 2003. This means that the bulky
waste volume has quadrupled in the years between 1991 and 2002.

3.2.3 Biogenic municipal waste (organic waste)
The separate collection of biogenic municipal waste and its recovery has been part of the Styrian
waste management since 1989 and was laid down for the first time in the "Styrian Waste Management
Concept 1989".
The collection volumes of individual waste management associations differ from each other, as the
associations apply different strategies in the collection of biogenic waste. Some associations
encourage collection in organic waste containers, whereas others pay particular attention to recovery
by home or community composting in the immediate household area. Figure 10 shows the
corresponding trends since 1991.
The calculation of the volumes which are collected and recovered by home or community composting
can only be determined with the municipalities' participation and by nature underlies a certain
inaccuracy. Within the annual communal waste analysis, the municipalities are interviewed on how
many households perform home or community composting and on the extent to which the households
make use of the collection in organic waste containers. The potential of home or community
composting is linked to the data provided by the municipalities and the results of the organic waste
container collection, whereupon a rough estimation can be provided.
