Just Imagine a world where there is no concrete. Concrete is considered as the top most construction material in quantity and application that is used throughout the world. Concrete is everywhere starting from our roads, our homes, bridges to huge buildings and dams. Concrete has become the signature construction material of our planet for the past 200years.
Carbon Dioxide Emission From Concrete Construction
The emission of carbon dioxide has increased a lot due to the initial stages of cement manufacture and the process of cement plus water reaction. This has thus become a greater source of the green house gas emissions. The studies have shown that 5% of the green house gas emissions are from concrete.

The second main source is from the flue gas that is emitted from the smokestacks of the power plants that are located around the world. These sources are largest sources of harmful carbon dioxide emissions.
Development of CO2CRETE
A team of interdisciplinary researchers at UCLA has been working for a long period to come up with a solution to eliminate the CO2 emission from the concrete manufacture. Their solution was based on bringing a new building material. For this, they captured the carbon dioxide from smokestacks, power plants and created a new material called as CO2CRETE.

The fabrication of this concrete is done with the help of 3D Printers. This is called as up cycling.
J.R. DeShazo, professor of public policy at the UCLA Luskin School of Public Affairs and director of the UCLA Luskin Center for Innovation stated that this technology will take the cause (Carbon dioxide) that is considered as a nuisance to the environment and converts to a valuable resource.
This technology is a complete game changer for the climate policy as well as the construction industry. CO2CRETE can help in solving the global climatic change the planet is facing and will face in the coming century.

The most challenges faced by the researchers in this field is that they instead of straight away bringing up a building material from carbon dioxide, they are trying to bring up with a solution or process for converting the CO2 to the building material. This process has to be unique and independent material.
