Marine bioplastic pigmentation and carbon capture: From algae to architectural surfaces

The overall aim of this PhD project is to investigate how microalgal and cyanobacteria can be used to capture CO2 and produce novel building materials designed to store carbon in the built environment.

The primary project focus is on the use of pigments from micralage and cyanobacteria that can be incorporated into biopolymers to create coloured materials for interior and translucent architectural applications.

The research will develop a calibrated colour library and blending protocols for microalgae and cyanobacterial pigments (e.g. lutein, astaxanthin, chlorophyllin, and phycocyanin). It will examine uniform pigment dispersion, colour blending, and stabilisation against UV light and oxygen.

Material performance will be evaluated through accelerated weathering, heat fastness, scratch resistance, and cleanability testing. Other carbon storing materials may also be explored (e.g. microalgal charcoal products that support C-storage).

Processing and compliance mapping will inform demonstrator splashbacks, partitions, and light-modulating panels. Recyclability and solvent-free finishing will be evaluated. Pigment yield, cost, and blending data will inform biorefinery simulations.

The application proposes one PHD scholar over 3.5 years. Funding and scholarship terms. Conversion of residual biomass to carbon-containing materials is a time- and resource-dependent stretch goal.

The project brings together UQ expertise in microalgae production, pigment isolation, polymer processing and architectural prototyping, with Greenalgi as the proposed industry partner.

The application identifies Centre for Solar Biotechnology pilot and laboratory facilities for microalgae production and pigment isolation; facilities for pigment-plastic blending and moulding; and architectural infrastructure for prototype development.

Planned methods include injection moulding, thermoforming, robotic forming and accelerated weathering. Equipment access, project location and supervisory arrangements.

This project is supported by the Research project scholarship.

Your application will be assessed on a competitive basis.

We take into account your:

• previous academic record
• publication record
• honours and awards
• employment history.

A working knowledge of pigment chemistry, polymer processing, colour measurement, or materials testing would be of benefit to someone working on this project.

You will demonstrate academic achievement in the fields of chemistry, biotechnology, chemical engineering, materials science, and the potential for scholar success and the potential for scholastic success.

A background or knowledge of bioplastics, laboratory experimentation, architectural prototyping or circular biorefinery processes is highly desirable.
