In 2000, the biowaste collection was <strong>in</strong>tensified <strong>in</strong> the 21st und 22nd Viennese Municipality
Districts. Dur<strong>in</strong>g 2001-2002, it was successfully extended onto the other outer districts. In the
progress of this reorientation, public bio-b<strong>in</strong>s have been removed. Each garden owner has
been offered an own bio-b<strong>in</strong> at his disposal. In parallel, empty<strong>in</strong>g sequence has been
reduced from twice down to once a week, so to ensure a greater fill<strong>in</strong>g grade of the
conta<strong>in</strong>ers.
A number of experiments have detected a quite low amount collected (and thus too high
collection costs) <strong>in</strong> the <strong>in</strong>ner districts, with the material prov<strong>in</strong>g also a negative impact on the
compost quality.

Utilisation of biowaste material as a resource for compost production demonstrates vividly
the waste-and-resource recycl<strong>in</strong>g cycle. Approximately 30% of the <strong>in</strong>itially collected organic
material rema<strong>in</strong>s as high-quality compost at the end of the production cycle. The product is
distributed, free of charge, among the Viennese agricultural companies (<strong>in</strong> 2002: 20.690 t
be<strong>in</strong>g ca. 60% of the total compost amount), the forestry (ca. 30%) and private buyers and
small garden unions (<strong>in</strong> total ca.10%).
