Natural utilization of sewage sludges is an economically justified method of their disposal. However, the sludges destined for utilization in the natural environment must fulfil relevant requirements concerning chemical composition and the sanitary-hygienic features defined by the stipulations of law [2 – 5]. Many years lasting studies of sewage sludges conducted at the IOŚ-PIB (Institute of Environmental Protection – National Research Institute) allowed for determining the possibilities and tendencies of the nature utilization of these sludges on the example of small and medium size towns of Dolnośląskie Voivodeship.

The program od nature utilization of sludges for the particular
sewage treatment plant should be elaborated on the basis of investigating
possibility of their utilization in the close area. Expenses born for
processing and utilization of sewage sludges are considerable but
unavoidable due to the requirements of ecology related to production
of wastes in the sewage treatment process. In case of small and medium
size sewage treatment plants, undoubtedly less expensive and simpler
solution will be the nature utilization of sewage sludges preceded
by their relevant processing.
