The concrete of carbon dioxide will make the planet cleaner
Greenhouse gas emissions are causing global warming, however, one company has found a way to use it in concrete production. Now carbon dioxide will on the contrary serve to reduce global greenhouse gas emissions.
Experts have developed a way to add carbon dioxide in the production of concrete blocks. Their patented technology CarbonCure system (CCS) uses a garbage carbon dioxide from major issuers, refineries, and factories for the production of fertilizers. A chemical reaction in the production is the reverse process of using traditional cement as the main component of concrete.
Production of construction cement accounts for about 5% of all anthropogenic global emissions of carbon dioxide, according to the report in 2009 according to the International energy Agency (IEA).
If You look at the concrete, the cement in it is derived from hard limestone CaCO3, which is heated in a cement kiln, which releases one molecule of CO₂ for every molecule of lime. We use the reverse of this reaction recovery, while the concrete becomes harder, according to Robert Niven, founder of CarbonCure. Companies that will take advantage of the development, will not only reduce the cost of energy consumption in the production process, but also be able to rely on the promotion of green certification of buildings, such as LEED.
When upgrading your equipment to use the new technology, manufacturers can achieve the triple effect: concrete is cheaper, stronger, and environmentally safer. It is a distinct advantage. The company noted that 100 000 grey concrete blocks can absorb as much carbon dioxide, how many will learn for the year, 92 adults tree.
