살아있는 건축물: 더 깨끗한 도시를 위한 박테리아 콘크리트

A team of engineers from the prestigious university, ETH Zurich, has introduced a novel construction method that uses photosynthetic bacteria to reduce carbon emissions and strengthen concrete structural support. The living architecture could have a resounding implication on future building designs. Here’s what you need to know.

이산화탄소

Carbon Dioxide is one of the main greenhouse gases that contribute to climate change. This chemical composition can cause irreparable damage to the ozone layer, local ecosystems, and your health over time. When CO2 levels go unchecked, it can result in some catastrophic changes, such as altering the oceans’ PH.

CO2 제거는 큰 비즈니스

All of these concerns have led the world to make a concerted effort to reduce and remove CO2 from the atmosphere whenever possible. To date, engineers have created a variety of ways of accomplishing this task. From special filters to materials that convert the chemical into other, less harmful minerals, there has been no shortage of originality.

Concepts like direct air capture systems and reforestation seek to remove carbon from the air directly. These approaches have proven to be effective. However, they are expensive and not easily upscaled to meet the global demand for these services. Recognizing these limitations, a team of scientists sought out a way to integrate CO2 capture into daily lives without hindering them.

살아있는 건축 연구

The 광합성 살아있는 재료를 이용한 이중 탄소 격리 study¹, recently published in the journal Nature Communications, highlights the use of bacteria mixed into construction-grade concrete to capture CO2. To accomplish this task, the engineers utilize one of the oldest life forms in the world, Photosynthetic cyanobacteria.

This bacterium is capable of conducting photosynthesis, which removes CO2 from the air, without compromising the concrete’s stability or strength. To that extent, the team envisions a future where city blocks can autonomously clean the air via their buildings.  These buildings can sequester and store the CO2 directly, reducing costs and improving air quality significantly.
