The purpose of this Master’s thesis is to analyse the environmental impacts from one-way or returnable systems for the project “Zero Waste Jam“. This project focuses on utilizing surplus fruits from big cities and urban areas and uses these for food production instead of disposing them. In this study, predominantly donated fruits from private and commercially operated orchards are used. Based on the experience of project operators, scenarios were developed using Life Cycle Assessment (LCA) to shape the overall environmental impacts which emerge as part of production, distribution, purification, re-use and recycling as well as waste disposal. In this thesis we focused on the analysis of the environmental impact of 30g, 150g and 450g jars. Operators of the project “Zero Waste Jam“ use conventional dishwashers or wash by hand and sterilize the jars using hot air sterilization in an oven. For the collection and distribution of jars, means of transport such as cars, public transport (subway) as well as cargo bicycles, are available. However, there is no logistic system for the collection established leading to additional environmental consequences due to transport routes which are not ideal. By comparing the two systems, it’s possible to create guidance for the operators of “Zero Waste Jam“, to keep the environmental impact arising during the course of the project as low as possible. Results demonstrate that returnable systems have an apparent ecological advantage compared to one-way systems. Except for the impact category of eutrophication potential for jar sizes of 150g and 450g, re-usable jars show a significantly improved environmental performance in all other considered impact categories.
