Remanufacturing is a production practice that requires the work of producers, consumers, and the government. There are benefits associated with this production model, such as improving the environment, opportunities for cost savings, and others. However, it is essential to identify the factors that affect the possibility of acceptance of this production model. This research proposes a model based on different analysis methodologies and techniques of SEM (Structural Equations Modeling) and the method of PLS (Partial Least Squares). A total of 403 responses to the survey were collected from 1 November 2021 to 15 January 2022. For the data treatment, SPSS, Excel, and WarpPLS software were used to identify the variables, factors, and their direct and indirect effects among the latent variables, referring to a scheme focused on consumer perception based on the acquisition remanufactured products. This created model served as a reference to create and develop a design and repair strategy for White goods or similar products in handling, logistics, and repair. This design strategy was transformed into a business model based on a circular economy, particularly on a Product–Service System with social, economic, and environmental benefits for producers and consumers.

The validation of processes is an innovative methodology where a process has been submitted to scrutiny to guarantee the products comply with the specifications of the company and the norms of the country of consumption. In the medical industry, this process is considered as a regulatory requirement, however, this also helps to improve quality, eliminate waste, and reduce costs, among other things. This chapter applied the methodology of process validation in a medical device company; the engineering tests were used in the company's clean room, using an injection molding machine and tests of several parameters were used even without being validated to know which are the best run and the best parameters, for its daily use. This project addresses the validation of the blood filter process by injection molding. The Design of Experiments applied was a 2K factorial design with central points where the replicas consisted of five of 45 in total for the three dimensions. The pieces are shared for those three dimensions that are being evaluated.
