storage conditions, production code, date, intended use, instructions for use and details about

public health must be stated. In addition, compost should not cause any odor after application,
in terms of human health; It should not contain glass, wire, metal and hard plastic. The limits

in the standard are shown in Table 16.

In Austria, the Ö-NORM S 2200 standard was developed for compost quality. This standard

was developed by research institutes and universities in Austria, Germany, the Netherlands and

Switzerland. Experts have not determined a limit value for organic substances in compost and
accept that these substances have a self-limiting feature because they stop the compost process.

In Austria, there is a procedure that must be implemented to maintain the quality of compost,
and according to this procedure, the quality of compost is checked every two months by

government organizations or institutions authorized by the state. The use of compost as fertilizer
is limited to 7 tons/ha/year, and as a soil improver to 10 tons/ha/year by Ö-NORM S. Austria's

Ö-NORM standard is shown in Table 17. In Austria, all waste is collected by municipalities.

Centers are established to collect organic waste, and organic waste is accumulated in these
centers. These centers are close to living centers. Transfer stations have also been established

for compost facilities with a distance of more than 30 km. Waste is first collected at these
transfer stations, and from there it is transported to solid waste compost facilities [53].
