The Bahamas has built the first house using an alternative type of concrete. The building is unique in that it is able to absorb CO2, writes The Verge.
The project is led by basketball legend Rick Fox. Together with architect Sam Marshall, he founded Partanna, a startup producing environmentally friendly building materials.
With the help of specialists, the partners have developed a way to make concrete without using carbon-intensive cement. The details of the process are not disclosed, but Partanna claims that the mixture is able to harden at ambient temperatures.
The company also claims that the components of the mixture absorb CO2 from the air and retain it in the material. A house made of this material continues to absorb CO2 and will retain it even after demolition.
According to expert estimates, the 1,250-square-foot structure absorbs as much CO2 as 5,200 mature trees in a year. The Bahamian government is currently working with Partanna to build a total of 1,000 homes using the unique technology.
