Celitement, A New Green Cement Innovation

The article "New Chemistry, Less Energy Could Yield Greener Cement" written by Andrew Curry in the National Geographic News, says that cement production caused a big problem. Cement production emits a huge amount of carbon dioxide that can lead to pollution. Andrew offers a new method of solving this problem and it's called the Celitement. This innovation is very influential and eco-friendly. However, the price is relatively more expensive than the normal cement. It's a breakthrough innovation, but it needs to be more economical to be distributed to the public.
The Celitement is an eco-friendly innovation due to the less amount of carbon contained. By having a less carbon emission, it could help reduce the effect of climate change. A conventional cement usually named as "Portland Cement" produce nearly billions of tons of CO2, which is a huge problem towards the environment. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO2. (Rubestein, 2012).

Instead, the Celitement could achieve emission reductions of up to 40% (Huang, 2016). The Celitement could cut the massive amount of carbon footprint (Berg,2013), which reduce the amount of pollution. The Celitement is far more eco-friendly than the Portland cement. Moreover, the production requires less energy. This involves energy efficiency savings in the production and supply chain. These could result in savings of between 60 Mt CO2/year and 520 Mt CO2/year, according to the IEA.

Furthermore, the Celitement produce a better quality than the Portland cement. CEO of the Celitement company explained that Celitement uses a low calcium mixture for its raw material which makes the product more efficient. Production of the Celitement is achieved at temperatures below 300 degrees Celsius. Compared to the Portland cement, low process temperature and reduced limestone content economies substantially on energy. The efficiency of an industrial plant is highly dependent on the use of automatable systems for production and quality control (Peterson, 2014).

It has a homogeneous composition which enables easy control of hardening and product quality. It also has a good durability and resistance because it is highly connected silicate building units and low porosity. The Celitement has a little efflorescence due to pure CSH phase and extremely low heat of hydration combined with high early strength (Asner, 2016). It's shown that the Celitement have better features than the conventional cement.
Celitement is almost perfect at its quality, however, the price is expensive compared to the Portland cement. The scale of price is about 1:3 in dollars (Kurtzian, 2014). The production and manufacturing cost are the obstacles of a high price. Ratzenberger 'from the Wall Street Journal also agreed that Celitement needs more financial help since it's an innovative product. This innovation needs to be spread equally towards the entire world to eliminate the use of Portland cement, which could lead to a better environment.

But, if the price is still high then not everyone can afford it. Only the developed countries like China, USA, and Germany that can yield the Celitement. The less developing countries, for example, Indonesia, needs more financial help. Both the investors and government should pay more attention to it because it's the key to a better future. The investors should look towards the opportunities of the Celitement instead of relying on investing the conventional cement.

The Celitement creates a product that consumers always want, it is eco-friendly and better quality. The Celitement business has a great prospect ahead, so this innovation needs more development. The development means more funding for researchers, technologies and marketing costs. It's an unfortunate if this innovation is unnoticed and only famous among the laboratory.

Consequently, the Celitement is an astounding innovation that can replace the conventional Portland cement. It has an eco-friendly feature by not producing a big amount of carbon emission which reduces the effect of climate change. It also creates a better quality and needs less amount of energy. However, the product is not well distributed towards the entire globe due to its high price. Sometimes a great quality is afforded a more expensive price. It's better if the production cost can be reduced by collaborating both the investors and government.
