Cover Story: The fishing industry produces large amounts of wastes in fish markets and in processing industries, and part of these unwanted materials are sea urchins’ shells. It would be of interest for a broad audience to reuse shells as an example of circular economy. To this end, we show that convenient extractive techniques exist which are easy to be implemented on the base of automated devices and do not require special expertise. The presented strategy is capable of providing natural essential fatty acids and their esters to be used in a number of diverse industries (e.g. cosmetics, foods, pharmaceutical). View this paper.
