The idea of eco-friendly construction is ceasing to be utopian and is becoming reality. Scientists around the world are developing materials that replace concrete and metal, and sometimes continue to “live” after installation.
In Australia, Professor Ben Hankamer’s team has developed 3D-printed RoboBlox bricks made from microalgae. They retain photosynthesis, release oxygen and clean the air. In Sydney, panels made from algae and oyster shells are being tested for compliance with standards.
In the UK and Denmark, walls with cyanobacteria are being tested: these materials not only capture CO2, but also strengthen over time. In Europe, houses made from compressed straw that have passed fire safety tests are in demand, and panels made from mycelium and bamboo have won international awards.
Experts note that success depends largely on laws: in Denmark, conditions have already been created for introducing new technologies. Architects are increasingly talking not about dreams of green cities of the future, but about concrete projects that are already being “grown” today.
