Paragraph starter

The selection of modified starch as a material for this design project is supported by research indicating that while native starch possesses desirable biodegradability and abundance, its inherent limitations in mechanical strength and water resistance necessitate modification. Chemical modification techniques, as highlighted by Amaraweera et al. (2021), are particularly effective in enhancing these properties, enabling starch-based materials to be viable for applications such as sustainable packaging and adhesives, thereby aligning with the project's sustainability goals.
