Today, we highlight the essential role of Aitiip Centro Tecnologico, whose expertise in compounding and bio-based material formulation directly contributes to the development of the bio-pellets used to manufacture our demonstrator: a biobased waste-bin lid.

One of the key innovations introduced by AITIIP is the use of a hot air drying conveyor belt, a crucial enabler for producing high-performance wood-fibre–reinforced bio-pellets.

As shown with the top left picture, the Hot air drying conveyor belt consists of an insulated conveyor belt in a controlled atmosphere. An air conditioning system above the conveyor belt cools the extruded bio-pellets without the need for water, thus avoiding the introduction of additional moisture.

Once the materials for scale-up were selected, additional characterization tests are performed on the bio-pellets. The data obtained from these tests are then used as input parameters for the overmolding process simulation model, that will be explained later on.
