Potentials for the prevention of municipal solid waste

Area of Science:

• Environmental Science
• Waste Management Policy

Background:

• European waste management law prioritizes waste prevention.
• Current initiatives have not halted the annual increase in European waste generation.

Purpose of the Study:

• To quantify and analyze the prevention potential of specific waste streams.
• To assess measures that do not necessitate reduced consumption.
• To examine theoretical household waste prevention potential in Vienna, including barriers.

Main Methods:

• Analysis of selected case studies: advertising material, beverage packaging, diapers, food waste, and event waste.
• Theoretical modeling of household waste prevention for Vienna.
• Identification of barriers affecting achievable prevention potential.

Main Results:

• Individual prevention measures can reduce specific waste streams by up to 10% (e.g., advertising material, beverage packaging).
• The overall impact on municipal solid waste is estimated at 1-3%.
• Prevention potentials appear relatively small when compared to total municipal waste volumes.

Conclusions:

• Despite high legal priority, waste prevention has limited impact on overall municipal solid waste quantities.
• Methodological challenges, including data scarcity, hinder precise impact assessment.
• Further research is needed to fully understand the ecological, social, and economic effects of waste prevention.
