The present work presents the application of the Quality Function Deployment tool, “QFD” for its acronym in English, used to translate the needs of a consumer into technical specifications that are responsible for meeting customer expectations. In this case, the analysis is oriented toward the future conceptual manufacture of disposable biodegradable cups made mainly with polylactic acid (PLA). The preliminary stage of the QFD consisted of developing a series of survey questions aimed at a representative sample of university students, where the key requirements that a biodegradable cup must have according to customers were determined and their hierarchy of importance was established. Thus, based on consumer requests, technical specifications were proposed to satisfy their needs; specifically, the material composition, molding conditions, wall thickness, container geometry, surface finish, color and cost were defined. The analysis showed that biodegradability constitutes the attribute most valued by the respondents, while the molding process and cup thickness represent the technical factors with the greatest influence. The QFD results showed correlations between customer requirements and technical specifications, resulting in quantitative prioritization oriented towards future experimental stages. The application of the QFD methodology led to a search of scientific literature.
