Cement is an irreplaceable component in constructing buildings. It is also a major contributor to Carbon Dioxide. Cement is the third in ranking for producing anthropogenic CO2. About 4-5% of total carbon dioxide emissions are due to cement.
A house is a basic need and requirement. Cement being an irreplaceable component makes it a necessary evil. Many research has been going on to find a solution to this conundrum. Be it about finding a replacement or finding ways to reduce CO2 emissions. Once such research has yielded a highly promising result.
The research for the sustainable cement
Novacem Cement is the product of hard work and long research conducted by Novacem Company. What makes their cement truly special is the fact that it has a carbon negative footprint. Carbon Negative footprint means that the product or entity has less than neutral carbon footprint resulting in absorbing of carbon dioxide from the atmosphere. Something which we need right now because of the exponential rise in the CO2 level in the atmosphere.
Novacem Cement is made of Magnesium oxide and hydrated magnesium carbonates. Their method of production of cement involves magnesium silicates to be rapidly carbonated under high temperature and pressure. This gives us carbonates as products. These carbonates are again heated at low temperatures giving Magnesium oxide and CO2. The byproduct – carbon dioxide is recycled back in the process.
What makes Novacem Cement eco-friendly
Novacem Cement requires lower temperature levels for its production than the currently in use cement. This allows the use of fuels having low energy content or carbon intensity, meaning that carbon emissions due to the usage of high energy content fuels eliminated. This further reduces the carbon emissions. The production of carbonates, a component in manufacturing Novacem cement, required absorption of CO2. Around 100kg of CO2 is absorbed while making 1 ton of Novacem Cement. This is much more than what it emits, making it a carbon negative product.
