Reclaiming Construction’s Carbon Dioxide for Sale

Nov 29, 2017

Existing commercial and residential buildings account for 39% of all carbon dioxide emissions. Another 10% of the world’s carbon dioxide emissions comes from construction. Some estimates say that over 90% of the latter is due to the production of steel, concrete, and wood for construction. Researchers conclude that completed projects and new construction sites account for nearly one half of all carbon dioxide emissions in the world. Recently, many of those researchers have been looking at ways to remove carbon dioxide from the environment.

We must find ways to remove and store carbon from the environment by 2030 according to a recent study by Chatham House. There are even studies looking at ways to convert or use carbon dioxide as a fuel. This particular set-up featured in the video above and in an article below is called a direct-air capture system. Climeworks, a Swiss company, can capture 900 tons of carbon dioxide over the course of a year. They then send the captured carbon to enhance the size of vegetable produce in a large greenhouse located nearby. It all begins with a fleet of 18 fans, each the size of a washing machine. Placed on the roof top of the recycling center, the fans, which are the size of a shipping container, take air in through chemically coated filters which absorb the carbon dioxide. After a few hours, the saturated filters are heated to 100 degrees C with energy from waste at the recycling plant. In the end, pure carbon dioxide gas is siphoned off.

Can you imagine a shipping container at a construction site filtering carbon dioxide from the environment to be heated and collected as pure carbon dioxide gas for sell? It could be an extension of the construction business improving the environment and the bottom line.

Read this article about the swiss system capturing carbon dioxide from the air and reselling it, also the removal and storage of carbon from the environment.
