Nanocelluloses (NFC) gained substantial attention in recent years as reinforcement of composite materials due to their excellent properties. One promising approach to yield high fibre volume fraction NFC composites is to laminate nanopapers. Thereby, the characteristics of the nanopapers directly determine the properties of the composites, hence, excellent mechanical properties of the nanopapers are desired. Nonetheless, aiming at ecologically sound solutions, also the raw material of the NFC needs to be considered. In this regard, utilizing agricultural waste rather than high-grade resources (wood) as base material would be vital. We have identified elephant manure to be a suitable precursor for the preparation of NFC, for elephants digest only about 35 % of their diet. Accordingly, their excrements contain large quantities of fibrous cellulosic material, whereby the ingestion and digestion already initiates fibre break-down. Thus, utilizing the elephant as first-stage bioreactor for the defibrillation of cellulose fibres by mechanical and chemical means constitutes an energy-efficient approach for the production of NFC. We demonstrate that by chemical purification of elephant manure, cellulose nanofibrils can be isolated from which papers were produced that had better mechanical properties than most common unmodified NFC nanopapers thus being ideal candidates for the preparation of nanopaper composites.
