Function-driven LCA - Case study of yoghurt packaging

Many food packaging LCA studies involve comparative evaluations of packaging materials without dealing with packaging functions. Researchers at the Technical University of Munich in Germany used a function-driven approach tailored to a specific example of yoghurt packaging to define the functional unit.
Key mechanical and barrier functions of yoghurt packaging were expressed and quantified in terms of function-driven parameters. The approach uses the cradle to gate non-renewable energy use and greenhouse gas emissions of the packaging material to exemplify the application of defined function-driven parameters as a basis of comparison. An article about the research is published in Procedia CIRP.
