Abstract

Although drawing inspiration from live animals to develop processes, technologies, or materials is not a new approach, there is rising interest toward biomimicry for implementing new ideas. This review presents the mechanisms and strategies of mechanical pretreatment developed by animals to enhance the digestion of their food. There is ample data in the literature describing animal digestive systems; however, very few compilations encompass all clades with a main focus on mechanical pretreatment. The objective is to improve, through a bioinspired approach, the design of anaerobic digestion processes that are comparable but less efficient than animal digestion. To assess the variety and diversity of strategies that animals have developed during their evolution to adapt and optimize this pretreatment step, the following items were identified, classified, and related: (i) types of mechanical pretreatments, (ii) organs used, (iii) body location of mechanical pretreatment organs, and (iv) substrates, according to their accessibility. Animals are found to have converged toward several solutions to mechanically process their food. The type of organ is associated with the phylogeny while the type of pretreatment is rather associated with the type of food protection. Grinding is the most commonly used pretreatment, covering the widest range of substrates and ensured by the largest number of organs. Finally, animal pretreatment strategies and industrial grinders are compared and discussed in order to identify potential technological improvements.
