Developing of Design Criteria Considering Sustainability Performance of Food Processing Equipment While Investigating Sustainable Soluble Gas Stabilization Design Concepts

This master thesis focuses on the implementation of sustainability objectives in the design phase of industrial up-scaling for food processing technologies. The main objective is to develop guidelines for incorporating sustainability principles through the utilization of the United Nations' SDAG (Sustainable Development Analytical Grid) tool, which draws inspiration from sustainability-oriented innovation, design for environment, and Sustainability by Design. The study engages key stakeholders, particularly an FPE manufacturer, to assess the existing industry's sustainability performance, until finally primary and secondary design criteria are identified. Using a systems engineering approach influenced by set-based product development, the thesis explores the optimization of inlet and outlet configurations for a Soluble Gas Stabilization Food Processing Equipment (SGS FPE). A comprehensive set of design specifications, derived from the sustainable results of the SDAG tool and supplementary requirements, guides the evaluation and refinement of alternative SGS concept design solutions. The sustainability impact of the alternative design solutions are evaluated and can be compared, showcasing not only how to optimize a sustainable solution, but in general how to create, prioritize and utilize a specific list of sustainability guidelines. The guidelines aid in implementing all aspects of sustainability in the early design phase of new product development, while also exhibiting improvement area recommendations for industry stakeholders. Through the research, the significance of sustainability is underscored, emphasizing its growing importance, although challenges remain in integrating it with other critical aspects such as continuity, efficiency, and costs, especially in industrial up-scaling. The thesis provides valuable insights, offering guidelines for integrating sustainability objectives in the design phase of industrialization of food processing technologies. It contributes to the broader discussion on sustainable design in the industry and sets the stage for future research and practical implementation, while also having started the concept development of a preliminary SGS equipment design.
