Wheat Bran as a Biodegradable Filler Enhances Marine Degradation of Bioplastics

Incorporating wheat bran into poly(butylene succinate-co-adipate) (PBSA) bioplastics can accelerate their degradation in marine environments, leveraging an abundant agricultural byproduct.

Materials · 2023

Key Findings

01PBSA-wheat bran composites maintained good processability and mechanical properties up to 15 wt.% bran content.
02Wheat bran significantly accelerated the biodegradation rate of PBSA in a marine environment.
03Good filler dispersion was observed at low to mid bran concentrations, while higher concentrations led to poor dispersion.

Application

Design takeaway

Consider using agricultural byproducts like wheat bran as functional fillers in bioplastics to enhance their environmental performance, particularly biodegradability in marine settings.

How to apply

When designing products for marine applications or aiming for enhanced biodegradability, explore the use of PBSA biocomposites with wheat bran filler, optimizing the filler content for desired properties and degradation rates.

Project actions

01When selecting materials for a design project, consider the end-of-life scenario and explore options that minimize environmental harm.
02Investigate the use of agricultural byproducts as functional fillers to enhance material properties and sustainability.

Method & Evidence

AimTo investigate the effect of wheat bran content on the thermal, rheological, morphological, mechanical, and marine biodegradation properties of PBSA biocomposites.

MethodExperimental investigation and material characterization.

ProcedureWheat bran was compounded with PBSA at varying weight percentages (5-20 wt.%) using melt extrusion. The resulting biocomposites were processed via injection molding. Properties such as thermal stability, melt flow, morphology, tensile strength, and marine biodegradation were then evaluated.
