【T.TIPS 源.識】會「自癒」的新型「真菌磚」?
之前我們跟大家分享過「蘑菇大樓」,發現蘑菇內的「菌絲體」具有成為建築材料的潛力。除了把真菌當作材料,大家知道它還可以與「活細菌」混合,變成具備自我修復功能的新型減碳建材嗎?
直至今日,混凝土仍是最主要的建築材料,但其生產過程導致高達全球 8% 的二氧化碳排放量。面對如此龐大的碳足跡,尋求更環保的永續材料刻不容緩!
早前有美國大學研究人員發現一種由真菌和細菌製成的「菌磚」,有望在未來取代高碳建材。將能產生碳酸鈣的細菌注入緻密的菌絲體中,細菌通過生物礦化過程,會令原本黏稠柔韌的菌絲體硬化,形成更堅固的「骨狀結構」。在此結構下,細菌能維持活性並賦予建材自我修復、環境感測等特性,目前能存活至少一個月,未來更有望延長至數年之久。
雖然新材料的發展目前還未能與傳統混凝土相提並論,但「活建築」的減碳潛力絕對不容小覷。 隨著科技飛速發展,未來的綠色城市或許就是由這些會呼吸、自癒的建築組成!

【T.TIPS】“Self-healing” Bio-Brick?
We’ve previously shared the "Mushroom Building" and how "mycelium" has the potential to become a building material. Besides using fungi as a material, do you know they can be mixed with "living bacteria" to create a new type of low-carbon building material with self-healing capabilities?
To this day, concrete remains the most widely used construction material. However, its production process accounts for up to 8% of global carbon dioxide emissions. Facing such a massive carbon footprint, the search for more eco-friendly and sustainable materials is more urgent than ever!
Recently, researchers at a U.S. university discovered a "bio-brick" made from fungi and bacteria that could potentially replace high-carbon materials in the future. By injecting calcium carbonate-producing bacteria into dense mycelium, a process called biomineralisation causes the originally viscous and flexible mycelium to harden, forming a stronger "bone-like structure." Within this structure, the living bacteria remain active, giving the material traits like self-healing and environmental sensing. Currently, they can survive for at least a month, with hopes of extending this to years in the future.
While the development of this new material cannot yet be compared to traditional concrete, the carbon-reduction potential of "living buildings" is not to be underestimated. As technology advances rapidly, the green cities of the future may very well be composed of these breathing, self-healing structures!
