Guideline for Disposal of Residues from Wastewater Treatment in Sensitive Mountain Regions

In the research project entitled “Disposal of treated residues in Alpine areas”, the options for the disposal of residues (sludge) were investigated considering the existing ecological and economical perspectives. Issues of nature conservation, soil conservation, water conservation, agriculture and forestry, climate protection and waste management were included considering the legal and technical basis. In addition, hygienic and esthetic aspects were also taken into consideration. The energy and water supply and the wastewater and waste disposal systems were analyzed for 45 Bavarian mountain refuges. Experiences from operation of their supply and disposal systems were investigated. The problem of supporting decision- and policy-makers in managing issues related to waste water and disposal of residues was addressed within the context of this project. As a result, a guideline and a practical decision making concept for the disposal of residues from wastewater treatment in sensitive mountain regions were elaborated. This paper reveals insights into general assessment criteria that can support the quest for solutions to sustainable waste management in other protected areas and mountain regions. This study presents a guideline supporting Alpine Associations and technical and enforcement authorities while making decision on a sustainable residue disposal.
