<p><i>25th European Symposium on Computer-Aided Process Engineering</i> contains the papers presented at the<i>12th Process Systems Engineering (PSE) and 25th European Society of Computer Aided Process Engineering (ESCAPE)</i> Joint Event held in Copenhagen, Denmark, 31 May - 4 June 2015.</p><p>The purpose of these series is to bring together the international community of researchers and engineers who are interested in computing-based methods in process engineering. This conference highlights the contributions of the PSE/CAPE community towards the sustainability of modern society. </p><p>Contributors from academia and industry establish the core products of PSE/CAPE, define the new and changing scope of our results, and future challenges. Plenary and keynote lectures discuss real-world challenges (globalization, energy, environment, and health) and contribute to discussions on the widening scope of PSE/CAPE versus the consolidation of the core topics of PSE/CAPE.</p><ul><li>Highlights how the Process Systems Engineering/Computer-Aided Process Engineering community contributes to the sustainability of modern society</li><li>Presents findings and discussions from both the 12th Process Systems Engineering (PSE) and 25th European Society of Computer-Aided Process Engineering (ESCAPE) Events</li><li>Establishes the core products of Process Systems Engineering/Computer Aided Process Engineering</li><li>Defines the future challenges of the Process Systems Engineering/Computer Aided Process Engineering community</li></ul>
