Construction Sites to Become Carbon Neutral

For years, the construction industry has been one of the key components of the UK's carbon dioxide (CO2) emission, holding a vast contribution to global warming. Dr Phil Renforth from Heriot-Watt's research center has conducted a study for Carbon Solutions which led to promising results for future with lower CO2 emission rates.

 

For years, the construction industry has been one of the key components of the UK’s carbon dioxide (CO2) emission, holding a vast contribution to global warming. Dr Phil Renforth from Heriot -Watt’s research centre has conducted a study for Carbon Solutions that led to promising results for a future with lower CO2 emission rates.

 

Funded by the Greenhouse Gas Removal Program and publishes in the Nature Communications, the study shows that there is a possibility for the focus to be directed at capturing a significant level of CO2 from the atmosphere.

 

Composed of calcium silicate minerals, industrial alkaline materials are similar to naturally occurring elements of igneous rocks for example, basalt. Revealing that, due to their alkaline levels, materials such as concrete and steel slag, have the potential to trap more CO2 than anticipated the study highlights the elements off industrial alkaline and discusses the effects they have on the environment.

The chemical make-up means that the materials are far more reactive to Carbon Dioxide and there is an on-going study on potential methods to reduce these reactions.

Initially, the possibility of construction sites lowering their global warming contribution levels was considered a challenge however, as a result of recent studies, it has come to light that if industries could decrease the emissions by working with renewable energy, the remaining carbon dioxide combined with the alkaline could be enough to claim companies as carbon neutral.

 

Renforth said: “We found the forecasted global potential of these materials to capture carbon dioxide may be three to seven times greater than previous estimates based on current production.

 

“This will not be enough to make a drastic difference on current emissions but if industries combined this with an extensive reduction in emissions, it may be enough to tip the balance.”

 

It is suggested by the study that there is a possibility that a figure of 7.5 billion tonnes per year of CO2 could be “hidden” in other industries and will be realized after a drastic reduction in current emission levels.

 

Renforth continued: “Preventing climate change will require a range of technologies, as well as changes in our lifestyle. Locking up carbon dioxide using alkaline materials may be an important part of our toolbox.”
