Abstract
The worldwide consumption of crustaceans, mainly crabs and shrimp, has increased significantly over the last decades. Noteworthy is that this waste inherently contains high-value-added compounds, such as astaxanthin. Hence, it is economic- and environmentally beneficial to extract astaxanthin effectively and sustainably from seafood production wastes and thrive towards a circular economy.
Therefore, the objective of this work is three-fold: (i) to propose a novel integrated process for the extraction of astaxanthin-oleoresin (AXT-oleoresin) from crab shell wastes; (ii) to assess the environmental performance of this new process at an industrial scale in Portugal; and, (iii) to identify latent production and environmental bottlenecks as well as provide suggestions for process and/or model re-design.
A process environmental and human health impact must become an essential consideration when designing new processes. Henceforth, aiming at a more sustainable process development and production, by applying LCA at the early stage of process development, we aim to identify critical issues early on, then to re-design, and reassess. Hence, this study concludes that the side-by-side application of LCA modelling and experimental process development is the best proactive approach for designing new processes and strategies as early as at the experimental level.
