Future Island-Island Impact Cards. Stone Strategies – An investigation into a local, sustainable product for a circular economy

Challenge
Currently most building processes use energy intensive, single-use materials. Is there an alternative available? Locally sourced stone cut into standardised units would in theory offer a reduction in carbon emissions essentially because its production does not require the application of heat derived from fossil fuels.

Approach
Stone Strategies initiated an examination into a building product that has advantages on an island setting due to its potential recyclability. A practice-based research approach incorporated sampling and 1:1 prototyping in collaboration with a local industry partner to look at the design and technical challenges of manufacture and assembly.

Outcomes
Inspired by sustainable dry-stone walling of Rathlin Island, a prototype composed of standardised natural stone units was exhibited. Dissemination and discussion were facilitated through a public event with community, local and international industry participants. Outcomes included raising awareness of local geological resources, stone standardisation and the aesthetic qualities of local stone.

Learnings
Stone Strategies reveals how Northern Ireland is resourced in a material to decarbonise construction. While acknowledging limitations to the use of some stone types and the challenge of production costs, the project shows how to retrofit historic stone structures and demonstrates the potential to contribute to a local circular economy.

Impact
The project adapts a vernacular, low carbon technology to work towards an environmentally friendly future. A modular stone demountable system displays the sustainable, visually pleasing qualities of local stone. An event, exhibition and online platforms raise awareness of how use of this place-specific material can help support the rural economy.
