De Ceuvel
Abandoned shipwharf turned sustainable oasis
What did it take?
Blood, sweat and volunteers
De Ceuvel was built, piece by piece, by a large group of passionate entrepreneurs and volunteers, using mostly recycled objects such as used houseboats.

What we like
Low tech, high circularity
The clean technologies at De Ceuvel aren’t necessarily that difficult to realise. A low-tech, do-it-yourself philosophy underpins the design of De Ceuvel’s components, making it easy to be adopted by others.
> Aquaponic greenhouse: Herbs, fish and vegetables for the cafe are grown simultaneously in a closed-loop aquaopnic system.
> Heliophyte filters: This type of reed is known for its excellent filtration properties, breaking down polluting chemicals present in the soil.
> Circular cafe: Built using old wood from the former jetty’s. Vegetarian dishes and locally crafted beer are served to an audience of green-minded urbanites.
> Recycled houseboats: Hoisted on land, cut open, and insulated before being welded together again. Equipped with heat pumps and solar panels.

Unique aspects
Eat, work, shit, repeat recycle
Through experimentation, De Ceuvel aims to become as self-sufficient as possible by processing its waste in innovative ways. Around the houseboats phyto-remediating plants work around to clock to clean the soil. Food waste is used to produce biogas for cooking. Human faeces are composted, while phosphates are extracted from urine to be used as fertiliser. All this results in a net positive impact on the environment..

Herbs & Vegetables
A hydroponic system in the greenhouse is filled with different kinds of herbs and vegetables. Water filled with nutrients from the fish tank is watered over the plants, allowing them to grow fast without chemicals.

Fish & Phosphates
In a room below the greenhouse sits a giant water container filled with catfish. The excrements of these catfish are nutrients for the plants to grow. In return, the water is filtered so that the fish can swim in clean water.

Biogas from biomass
Food and plant waste from the boats and restaurants is valuable biomass that can be turned into biogas through a process called biodigestion. This biogas is then used again by the local restaurant for cooking. The circle is round again.

Inside the boats
Amsterdam's first circular office park
The former industrial plot is home to a thriving community of entrepreneurs and artists. What was once a shipyard has now been transformed into one of the most unique urban experiments in Europe. The plot now hosts several creative workspaces, a cultural venue, a sustainable café, spaces to rent, and a floating bed & breakfast.

How is SmartHoods involved?
Inspired to circularise
Although SmartHoods has had no direct involvement in the construction of De Ceuvel, we frequently visited the site in the past to help out. We helped to build the aquaponics system, and learned how to make better use of waste streams such as human excrements and wastewater. In addition, we modelled its energy system extensively to see what works and what can be improved.
