Flexural properties and thermal characterization of cyanobacteria biomass/PLA composites using powder compression moulding
Source abstract
Abstract
This study develops eco-friendly composites by blending polylactic acid (PLA) with cyanobacteria (Arthrospira platensis) using solvent-free planetary ball milling and hot-pressing. The objective is to address the industry’s plastic waste from non-biodegradable accessories. Results show that 3.5% Spirulina increased flexural modulus by 27% (4800 MPa vs neat PLA’s 3771 MPa), though strength declined maybe due to interfacial limitations. Thermal analysis revealed more homogeneous crystallinity, with melting enthalpy rising 14%. These composites, produced via green methods, offer sustainable alternatives for stiff, heat-resistant biodegradable accessories and parts. The work underscores cyanobacteria’s potential in reducing reliance on land plants and advancing circular manufacturing.
