Formatted Abstract/Summary The vegetation of arid and semi-arid regions of Australia is characterised by spinifexdominated ecosystems. Spinifex grasses belong to the genus Triodia, of which there are at least 67 species, and are broadly classified into hard and soft, resiniferous types. This paper draws on a multidisciplinary research project that examines the potential uses of two species of ô€€€pinifex as a material component of a range of sustainable building products. Novel findings on the botany, ecology, chemistry and bioengineering of Triodia spp. Continue to inform the architectural stream of this research, which is in the third year of a five-year project.

This paper describes preliminary investigations into the use of two species of ô€€€pinifex as potential materials for the thermal insulation of buildings. Recent data on the morphology and mechanical properties of Triodia pungens and T. longiceps are compared with plant-derived fibres, such as flax and hemp, which are used to make thermal insulation for buildings. A range of prototypical building products have been developed which investigate different processing techniques, binders and compositions. The paper discusses these results in the context of the wider research project and the potential applications for spinifex grasses, which are limited by inchoate knowledge of sustainable harvesting practices.
