GETTING THINGS DONE Ivormatie magazine - December 2022

2

Before we reach the end of 2022, it’s time for a new edition of Ivormatie. This time with the theme: ‘Getting things done’.

But more about that later. 2022 has been an extraordinary year so far. After several years of a global corona pandemic, everything reopened, and the Dutch economy seemed to recover rapidly. However, the (still) sky-high inflation and the war in Ukraine appear to be slowing the momentum of this recovery. Energy, fuel and goods: everything has become considerably more expensive. In addition, we are also struggling with a nitrogen crisis, a housing crisis, a personnel crisis, a refugee crisis and a climate crisis. In all this turmoil, safety, security and stability have become even more critical this year.

The theme ‘Getting things done’, or as Rotterdammers would say: ‘stop beating around the bush and get on with it’, has therefore not been pulled out of thin air. We have to buckle down and get to work to address all these challenges. Using our knowledge, experience, creativity and new technologies, we must find a way out of all these crises. We are ready to take on this challenge, and with all the knowledge we have accumulated, also in fields such as digitisation, energy transition and sustainability, we want to work on these specific issues and ultimately solve them.

Fortunately, we are already doing this. Opportunities are being seized throughout Iv to deliver our contribution.

Several of these magnificent projects are showcased in this edition of Ivormatie. And this is just the beginning. If we all put our shoulder to the wheel, we will succeed in consistently making the world a little better. So let’s get on with ‘Getting things done!’

I hope you enjoy reading this edition of Ivormatie.

establishing a practical application for its use? The answer is: yes, that’s possible.

The mineral rock olivine is used to absorb CO2.

Process Engineer Esmée Amsen and Senior Process Specialist Louk Eskens from Iv-Industrie have also been closely involved in this project. Paebbl deliberately engaged several engineering companies, one being Iv-Industrie. Louk and Esmée are performing the basic engineering for this pilot.

“It’s an extraordinary project to be involved in from the beginning. Normally, an engineering company would only be called in at a later stage of development when the concept is already there. However, this time, we have been directly involved in the thought process and have actively

Louk: “For us, it is a matter of gathering a lot of information and trial and error until we finally have the answers we seek. We are currently roughly three-quarters of the way through this process. It is an extraordinary project in the field of process and mechanical engineering to be involved in.”

What makes the startup of this project, founded a year ago, so special is that it is not about the cheapest and most efficient solution. On the contrary, it is about the most sustainable solution. This path was deliberately

“The best thing is that everyone involved with Paebbl is incredibly motivated to contribute and share knowledge and findings. Moreover, this enthusiasm is contagious”, says Esmée. “There is no urgency because of economic interest

but for nature’s sake. I like that.”

Several plant installations have now been developed: a medium-sized one that can, for example, be placed next to a paper mill to take up CO2 locally. And a large factory that connects to a pipeline and captures CO2. The goal of both is to help the industry sectors achieve CO2 neutrality.

It is a unique collaboration whereby all involved keep the others informed and up to date.

Feasible and scalable Paebbl’s goal is to make a significant impact. Starting small, like the test phase in Rotterdam, will form the beginning of that. “In addition, it must be feasible and scalable.

knowledge is essential for determining whether roof structures can support solar panels. Etienne: “You must understand structures and have knowledge about load distribution and the associated risks of renovating existing structures.”

But he also states that a quick scan of a roof doesn’t have to be rocket science. “Roofs are generally not the most complicated of structures. So, we always begin simple, and as a quick scan progresses, it becomes more complex. To assess a roof accurately, we begin with hand calculations, which later progress into a more in-depth calculation with the help of structural software.”

The quick scan is a financially sustainable way of getting more out of a roof than is considered possible.

However, a standardised quick scan method is new, no matter how logical the necessity and demand may seem. Etienne: “It also suits Iv-Bouw, and Iv in general, to observe these opportunities in the market and pragmatically devise a solution to close the gap.”

While the energy transition and the climate goals to be energy neutral by 2050 are being accelerated, the quick scan is a financially sustainable way of getting more out of a roof than is considered possible.
