In this study, hydric and biodegradability properties of cassava starch-based bioplastics reinforced with crude kaolin or treated kaolinitic clay at 700 °C called metakaolin were investigated using water adsorption and microbiological tests. Non-reinforced bioplastics (BP) and those containing 5 wt.% crude kaolin (BPKB) or metakaolin (BPMKB) were manufactured using the casting/evaporation method.

- The study investigates how "geomimetic" materials, combining lateritic clay and humic substances, are strengthened through chemical bonding.
- The materials are created by mimicking natural soil stabilization processes, utilizing fulvic acid and lime, and undergo a specific curing process to enhance their properties.
- Key strengthening mechanisms identified include chemical bonding between clay particles and fulvic acid, as well as partial dissolution of clay that leads to the formation of new cementitious compounds, with iron oxides playing a crucial role in binding these materials together.
