Egil Velde

CEO, Velde

Talk Title: The Norway Roads Project

About Egil...

Egil Velde and his brothers are pioneers of the circular economy in Norway and in a wider European context. Egil leads the family business based in Stavanger in western Norway as they continually explore the opportunities for recovered materials from CDW. The family operated C&D waste recycling plant in Stavanger, Norway is the largest of its kind in the world, and it has been operational since 2015.

Talking about the circular economy and recycling construction and demolition waste material, Egil explains: “With innovation, curiosity, and investment in modern technology, Velde will stand for the most sustainable and environmentally friendly production of raw materials.

Recycling is central to our value chain and all the products we offer can also be recycled. Thus we get the valuable potential of products that otherwise have to be handled as waste. As a bonus, large amounts of transport and energy are saved as we have co-located recycling and production.

Lift your eyes, look forward and help future generations also have access to raw materials when their cities are to be built. When we recover - everyone wins!”

Marjorie Petitpain

Dr. Marjorie Petitpain

Material & Civil Engineering Doctor, Circular Economy Department, Cerib

Talk Title: Re-using Construction and Demolition Waste Materials in Concrete – The Situation in France

About Dr. Marjorie...

Marjorie recently graduated as a Civil Engineering Doctor (2017) after three years of working on environmental precast concretes and low carbon concrete. The goal was to obtain concretes from recycled materials with similar characteristics (mechanical, durability) to concrete from natural material, while greatly reducing the environmental footprint.

Today, she works at Cerib (Precast Concrete Industry Study & Research Centre) on topics related to the circular economy for the concrete industry. The valorization of industrial co-products, construction, and demolition waste materials, excavated soil, quarry or mine materials or marine sediments are more and more encountered in this research.

Marjorie's skills make it possible to accompany various companies throughout the entire value chain of the industry to investigate new ways of recycling C&D waste in France and throughout the world.

Sven Henrik Norman

Business Development Manager, Environmental Solutions

Talk Title - Solutions for Returned Concrete and Non-Usable Fines from C&D Waste Processing

About Sven Henrik...

Sven Henrik Norman has been in the crushing, screening and concrete industry for 24 years following his graduation with an engineer's degree in 1992. Sven Henrik made the gradual move from sales and product management positions in rock processing equipment supplier companies like Metso Minerals and Sandvik into aggregate, asphalt and concrete production and recycling. Within Basalt AG from Germany, the Velde group and Ølen betong in Norway, Sven Henrik has broadened his view of the industry and deepened his knowledge in aggregate production, concrete mix design, and recycling solutions.

Sven Henrik worked on the implementation of the manufactured sand at Velde Pukk in Norway and more recently as a consultant developing manufactured sand for concrete made out of local crushed aggregate in major road and railway tunnelling projects in Bergen, Norway.

In his current position as Business Development Manager in Environmental Solutions at Mapei, Sven Henrik is part of a team that market and develop solutions aimed at increasing the recycling of returned concrete and reducing waste at Mapei’s own dry mortar plant in Sagstua, Norway. Mapei is a worldwide company producing building materials across 75 global plants, producing more than 5,000 products including adhesives, sealants, and chemicals, which are shipped every day for a total amount of 25,000 tons.

During his talk, Sven Henrik will focus on a product called Re-con Zero, discussing how it works, the economic and environmental saving it can contribute to and some new ideas that Mapei is currently developing for mixing in sludge or waste crushed concrete fines to develop recycled aggregates for concrete or CO2 absorbing materials.

What does a Circular Driven Economy mean to you?

To me, the circular economy is a concept in which materials are produced to be constantly recycled or re-used. It requires rethinking of design, planning principles, engineering, retailing, re-using, recycling and consumer adoption of its principles to keep resources in use for as long as conceivable in order to extract maximum value and preserve natural resources.


Kiran Pereira

Founder and Chief Storyteller, SandStories.org

Talk Title: The Sand Story

About Kiran...

Kiran Pereira is the Founder and Chief Storyteller of SandStories.org, a platform dedicated to raising awareness about the urgent need to manage our consumption of sand as a resource. She works with scientists, policymakers, and industry professionals to identify and promote potential solutions to the looming sand crisis. Kiran is also the author of a forthcoming book on the same topic.

During her talk, Kiran will provide a global perspective on sand mining and some of its impacts. She will look at some of the challenges that lie ahead in terms of availability of natural sand resources, and what we need to consider to ensure future generations aren't faced with a scarcity of sand resources.

What does a circular economy mean to you?

The Circular Economy is a fantastic opportunity to reinvent the way we make our world in such a way that our future generations don't have to pay the price for our lack of imagination.
