Meet for sustainable building in Koppelkerk


BREDEVOORT – There are currently more than eight billion people living on earth, and this number will continue to grow in the coming years. The question of how many people the earth can handle is therefore becoming increasingly relevant. How can we live and live with so many people without asking too much of the earth? One of the answers is sustainable lifestyle. But what does it mean to live sustainably? What raw materials can we build with? And where are the social bottlenecks and opportunities? On Friday 20 January, during the Meet Up in the Koppelkerk in Bredevoort, three interesting guests will talk about sustainable construction.

The world’s population is increasing and with it the demand for raw materials, food and land. In the Netherlands, we see population growth reflected, among other things, in an exponentially growing demand for housing. Despite the acute housing shortage, the construction companies have not yet completed construction. This is due, among other things, to the current nitrogen policy and a lack of materials. Are there still enough resources to build? And where do the raw materials come from?

Not in my backyard!
On a daily basis, we use many raw materials such as lithium, cobalt and neodymium. For many of the raw materials we use, the origin is unknown to us or a distant show. Who knew that even the better-known raw materials such as iron ore and aluminum ore come a long way from the Netherlands?
In Europe and the Netherlands, however, you can find and extract various raw materials, but the local population is often against it. “Not in my backyard!” is a slogan that regularly comes up when it comes to infrastructure projects. Raw materials are therefore now often bought on the world market. Although we do not want to be dependent and the raw materials are extracted under conditions that would not be tolerated in the Netherlands.
Nevertheless, the necessary minerals are also extracted in the Netherlands: mostly sand, gravel, clay and limestone in the East Achterhoek, among others. Without the extraction of such raw materials, no housing or road construction is possible. But are we always prepared to accept the consequences of extracting raw materials? Are there sustainable alternatives and where do they come from?

And what about the extraction of raw materials close to home: gravel extraction just over the border at Suderwick, lime extraction in Ratum and sand extraction at Groesbeek? Is it necessary or rather not? Or rather in the North Sea with all the consequences for the ecology of the seabed?

Talking to experienced experts
In Backlight Meet Up Bredevoort this evening we will examine the challenges of raw materials for construction. We do this in conversation with each other and three interesting guests. Guests are Leonie van de Voort, Gerard ten Dolle and Willy Smit. We talk to them about the challenges of finding the right raw materials for construction.

Leonie van der Voort is a Wageningen ecologist and director of Cascade, the industry association for sand and gravel extraction. Cascade is concerned about the availability of raw materials for construction in the medium term.

Gerard ten Dolle works for Sibelco and leads the work in the well-known Winterswijk quarry. Various grades of limestone are excavated in the quarry. There is also a processing plant where materials from countries outside the Netherlands (such as manganese ore from West Africa) are further processed into raw materials for industry.

Willy Smit also takes part in the conversation. He is general manager at WAM&VanDuren Bouwgroep in Winterswijk. This company focuses on sustainable and circular construction, including bio-based building materials. Smit was at Floriade last year with a design where surprising new materials for homes were shown.

Meet Bredevoort
Meet Up in the Koppelkerk provides Ahterhoekers with information about current developments in their environment. Not only do the three speakers speak, but the visitors also get the opportunity to share their knowledge and experiences.

The evening starts on Friday 20 January at 8pm and lasts two hours. The discussion is led by Jan Wijbrans. A free gift for the evening is appreciated. Registration is required and can be done via www. To watch the documentary and further information about the Tegenlicht broadcast:
