Sustainable Product Design Concept Metrics for Developing the Eco-Bag from Pineapple Leaf Fiber

Abstract

Sustainability is a critical issue to be considered by the product designer. Due to the increase in environmental impact caused by the production, sustainability should be implemented in the early phase which is concept development. This study aims to develop the eco-bag concept using the sustainable QFD method and evaluate the developed concept by using metrics for sustainable product design. QFD is used to measure and select the quantitative target and sustainability criteria, whereas the metrics are used to measure the concept evaluation; material, production, use, and end of life. The respondents of this study are career women and students (50 respondents). According to the sustainable House of Quality (HoQ) method, the criteria selected are material, bag size, and price. The score of the metrics concept evaluation is 6.25, which means the concept is good enough to apply sustainable design. This research improves the consideration of the sustainable aspect to facilitate designers in early product concept development.
