Bacteria, Food waste

The irresistible illusion of finding a solution

The majority of materials used for infrastructure development are non-regenerative aggregates whose extraction methods, trade and processing raise political, ecological and social tensions to various degrees in relation to their local availability.

'The irresistible illusion of finding a solution' is a material study on bio-concrete derived from abundant local waste streams. As the construction sector is one of the most resource and carbon-intensive economy sectors, resourcing from waste reduces the amount of virgin and non-renewable material needed for infrastructure development.

The process involves living microorganisms producing a solid calcium composite through biomineralization. This non-pathogenic bacteria has the ability to utilise the enzyme urease and secret calcium carbonate crystals. Once introduced into a waste material, the process of biomineralization creates a solid material, an alternative source of concrete, a circular material to avoid excavation and minimise irreversible human impact.
