SUMMARY The originality of the present study is to give complete and pragmatic information associated with the preparation of a totally bio-based composite. It covers the most relevant investigations from analyses of the fi bres used as reinforcing elements to the fi nal product acquisition and its recyclability analyses. This study is destined for packaging areas. It demonstrates the three-dimensional formation processes with these new kinds of bio-composites, as well as the recyclable features related to the prepared materials. Thus, several processing parameters were studied and a fi nal tray was prepared. The addition of the fi bres gives rise to an increase of the tray stiffness, when a fl exible biopolymer is used as a matrix. The prepared biocomposites were recycled several times (10 recycling cycles) and found that they maintain their most relevant characteristics. Thus, such bio-composites can be reused several times. All these data, including a prototype sample prepared as a demonstrator, support the innovative and sustainable character of the packaging materials described.
