Replacement research is a field of study that focuses on finding suitable alternatives or substitutions for certain materials, products, processes, or technologies. This research area aims to address concerns such as sustainability, cost-effectiveness, performance, and safety by identifying and evaluating potential replacements. It involves assessing the feasibility, functionality, and potential impact of the proposed substitutions, as well as analyzing the implications of transitioning from one option to another. Replacement research is interdisciplinary in nature and can be applied to a wide range of industries and applications.
