This paper aims to introduce a modified QFD model that incorporates sustainability criteria, as well as its application in a sustainable detergent case. The inclusion of these criteria takes place through an evaluation of the detergent components relative importance, which allows the reduction of product parts and the incorporation of a matrix for raw materials sustainability assessment. The model application allowed the prioritization of the detergent components, indicating which of them could be eliminated with minimal impact on the product demands. After that, the available raw materials were evaluated according to the sustainability criteria and were prioritized according to their relative importance to the final product. The results of this study indicated that the model proposed is adequate to industrial application, contributing to the development of more sustainable products, still driven by market demands.
