About

Local soil. Local possibilities.

From excavation
to a local resource.

Aarde Collective develops rammed-earth applications from excavated soil. Our work connects soil sourcing, mixture development and testing with building elements, furniture and objects.

Starting in Rotterdam, we are exploring production at or near existing soil banks: places where excavated earth is already collected. Our aim is to adapt mixtures to local soil and connect that material with nearby projects, reducing the need to move heavy earth over long distances.

Vision

Hyperlocality — from earth, back to earth

Around 45 million tonnes of soil are excavated in the Netherlands every year. What if we saw this earth as a new resource?

We aim to connect the entire journey of earth within the local area: from classifying and analysing excavated soil to producing and supplying materials, and using them in architecture and furniture. We envision a cycle in which locally sourced earth finds a place in our everyday lives and returns to nature when its use comes to an end.

Service

From excavated soil to built form

We develop rammed-earth walls and prefabricated elements from excavated soil. Pilot projects bring material research into construction, informing future applications in buildings, public spaces and small-scale infrastructure.

Brienenoord Greenhouse

On Brienenoord island in Rotterdam, we are developing a rammed-earth greenhouse pilot in collaboration with the Municipality of Rotterdam, supported by a €2,500 BK-Launch Startup Voucher. The project brings our research into excavated soil and earth construction into a built setting.

Beyond construction, the greenhouse is intended as a place to learn from the material over time. Twelve months of planned monitoring will examine heat storage, indoor temperature stability, weathering and movement between the walls and roof. These observations will help us understand how the construction behaves in use, rather than relying on simulations alone.

Together with our wider soil-bank research, the findings will inform mixture development and construction methods for future local projects. The ambition is to connect material knowledge with production close to the soil source, creating a practical basis for repeated local reuse.
