Luminara Greenscape

Luminara Greenscape aims to transform urban landscapes by integrating innovative technology with sustainable practices. The aim is straightforward yet profound: instead of traditional street signs, Luminara wants to replace them with geopolymer concrete structures that are covered in bioluminescent lichen. This will result in bright, green spaces that improve our cities’ visual attractiveness and environmental health. Centred around a dedication to community empowerment and involvement, Luminara Greenscape creates significant job possibilities while also improving the aesthetics of our metropolitan areas thanks to the enthusiastic involvement of the local populace. Cultivating a network of Lichen Stewards and Eco-Ambassadors, guarantees the healthy expansion of lichen populations, promoting a more resilient and greener urban environment. Not only does the symbiotic interaction between lichen and geopolymer concrete look good, but it also has important scientific implications. The colour of the lichen changes with air pollution levels, offering a visual representation of the state of the environment. This interactive feature engages communities and motivates the next generation to take up environmental preservation as a powerful teaching tool.

This model is a street sign that has been growing lichen.
An artifact showing how lichen growth in the city might look in 2033 could illustrate buildings encouraging lichen to grow on their walls by using geopolymer concrete materials. This would mean that air pollution-indicating lichen would be present on a much larger scale.
Lichen on this street sign glows under UV light, highlighting its presence and adding a unique luminescent touch to the urban environment.
