Living matter : biomaterials for design and architecture
For over a decade, we have witnessed a new emphasis in digital architecture on modes of production and material-based approaches rather than on form, geometry, and representation alone. As a result, fabrication techniques and material systems generally not accessible to architects can now become an …

Development of biomaterials from sustainably produced macroalgae feedstocks
Upgrading and maintaining large-scale wastewater treatment plants (WWTPs) is notably expensive, particularly in rural areas of New Zealand. Freshwater macroalgae ponds may offer a cost-effective alternative for wastewater treatment in these areas. These ponds produce significant amounts of residual …
