Change the concrete appearance that can reduce the cost of housing in Europe

According to the European Commission, the construction sector in Europe provides 18 million direct jobs and represents about 9 % of the mass GDP.

In addition, about 250 million tons of carbon are produced annually. This is equivalent to more than France’s entire emissions in 2023 (216.7 million tons).

With the commitment of the clean agreement of the European Union, which is formed in reducing emissions by 90 % from here to 2040, besides the need to continue the construction that is always present, something must change.

Concrete is the most used material in the world after water. Thus, when determining how to apply its innovative technology, although it can also be applied to plastic and vital common paper, Paebbl choose to focus on concrete to get the maximum effect.

In this episode of “The Great Question”, Angela Barnes talks to Marta Sjögren, Joint Founder and CEO of Paebbl, to talk about that technology that helps attract carbon dioxide in concrete.

How to hunt carbon dioxide in concrete?

It is difficult to remove concrete crochet because cement is also. In addition, for several reasons, it was not invented in cement. “The big question” said: “There was no incentive,” Marta said.

But among the climate urgency, complex supply chains that lead to an increase in prices and the general need for industrial flexibility, it is time.

PaebBL has developed a natural process that speeds up a natural process, usually centuries, only one hour.

By extracting carbon dioxide from the atmosphere, the gas is combined with magnesium silications or with calcium silications and a gas rock. After that, it is crushed to create an artificial filling that can be mixed with concrete, which reduces the amount of cement needed in the mixture.

For each ton of Paebbl materials, up to 300 kg of carbon dioxide is stored. According to IEA, the traditional cement emanates about 600 kg of carbon dioxide per ton. This depends on the amount of Paebbl, mixed with concrete, the concrete carbon fingerprint can be reduced by up to 70 %.

“The built areas, being a great source of emissions today, if we turn the equation, and if every building can store and guard a little carbon, this would give a lot of economic and environmental level,” Marta continued.

Will PaebBL technology achieve that construction is cheaper?

Although it is only a 3 -year -old company, Paebbl has already taken huge steps. The Amazon and Holcim supported, the largest cement manufacturer in the world. In addition, during three extensions of size, 1000 times have grown.

“We have just finished the demonstration factory in record time. It is usually average time to develop such a project in this sector from two to three years. We have achieved in about 15 months and a budget less than average sector: less than 10 million euros.”

“The next step will be to expand production to industrial size.”

Although PaebBL continues to production on a small scale, the cost of its materials is currently higher than the cost of traditional concrete components; However, as more growing and producing more quantities, this cost will decrease.

“We expect the prices to be more competitive. This is because we use carbon dioxide, which is usually a remaining flow, as part of the mixture.”

In addition, because it is negative emissions technology, carbon should not pay the payment.

In the long run, Marta expects this to contribute to reducing the cost of housing in Europe. However, it has highlighted the need for regulations that support the new material test and speed they can access to the market.

“I think private companies are a basic essence in this aspect. They offer an example when creating models on how to use areas created as a sustainable solution and saving money as well.”

“But let us not forget that most of the concrete, today, are present in public places. We hope that the public projects that were built in the ten or more of that will be a little, you learn quickly from the private sector, and thus allow a greater escalation of these technologies.”

‘The big questionIt is a series of “European Business” in which we met leaders and industry experts to discuss some of the most important topics in the current agenda.
