Overview
Background
Professor Bronwyn Laycock has a diverse background in translational research, working not only in academia but also in industry and as a consulting chemist as well as at CSIRO. Her research activities have ranged from bio/degradable polymers, composites, organic and organometallic synthesis, waste conversion technologies, and pulp and paper chemistry, to general polymer chemistry. She is currently working across a range of projects with a focus on materials for circular economy applications and management of the transition to the new plastics economy. The application areas in her research program include biopolymers (particularly polyhydroxyalkanoates), polymer lifetime estimation and end-of-life management/conversion technologies, biocomposites, controlled release matrixes for pesticide and fertiliser applications, polyurethane chemistry, and biodegradable packaging.
She has a strong history of successful commercialisation and impact, being a co-inventor on CSIRO's extended wear contact lens program (recognised as its fourth most significant invention) - for which she was awarded a joint CSIRO Medal for Research Achievement 2009. As a Project Leader and Deputy Program Leader within the CRC for Polymers, she also managed a project that delivered an oxodegradable thin film polyethylene that was commercially licenced by Integrated Packaging. This work earned the team a Joint Chairman’s Award for research/commercialization (CRC for Polymers) and an Excellence in Innovation Award (CRC Association).

Biodegradable polymers - Polyhydroxyalkanoates
Polyhydroxyalkanoates are microbially synthesised biodegradable polymers that have properties comparable with polypropylene. They can be synthesised using mixed cultures from wastewater treatment plants and fermented waste carbon streams, and have very versatile properties depending on feedstock. Not only are they completely biodegradable, even in a marine environment, they are also water resistant (unusual for a biopolymer).

Research impacts
Professor Laycock's research seeks to address some of the challenges around global sustainability and planetary boundaries, such as plastics sustainability, nutrient recovery and efficiency, controlled release formulations and sustainable materials for the circular economy, particularly bioderived materials for packaging, film and other applications, as well as plastics lifetime and impact estimation and end-of-life management.
