The book "Raw Materials Substitution Sustainability" offers an innovative approach to assessing the sustainability of raw material substitutions. It presents a simplified quantitative model that takes into account the embodied energy and carbon footprint of raw materials. In addition to this new model, qualitative concepts and numerous case studies are presented, complemented by helpful illustrations to clarify the concepts and approaches. Considering the numerous initiatives in Europe aimed at promoting research and innovation in the field of raw materials, the book highlights the challenges associated with the comparability of material sustainability and the creation of effective legal frameworks. It is aimed at scientists, researchers, policymakers, as well as industry and business stakeholders seeking ways to evaluate the sustainability of raw material substitutions.
