Starch consolidation of calcium carbonate as a tool to develop lightweight fillers for LDPE-based plastics.

Calcium carbonate (CaCO) is used as a filler to improve the stiffness and processability of plastics at low cost. However, its high density limits the quantity to be used. In this work, the feasibility of using starch consolidation of eggshells-derived CaCO (ES) to develop lightweight fillers for low density polyethylene (LDPE)-based materials was studied.

Graphene Derivatives in Biopolymer-Based Composites for Food Packaging Applications.

This review aims to showcase the current use of graphene derivatives, graphene-based nanomaterials in particular, in biopolymer-based composites for food packaging applications. A brief introduction regarding the valuable attributes of available and emergent bioplastic materials is made so that their contributions to the packaging field can be understood. Furthermore, their drawbacks are also disclosed to highlight the benefits that graphene derivatives can bring to bio-based formulations, from physicochemical to mechanical, barrier, and functional properties as antioxidant activity or electrical conductivity.
