Over the last years, I learned to weld both with MIG MAG and Electrode machines. Steel is 100% recyclable, which makes it one of the most ideal materials for upcycling.

Signboard This Side Up – Fairtrade Coffee
For the fair trade, circular coffee company This Side Up, I made this sign for in front of their factory in Amsterdam Noord. It is made from only Upcycled steel.

Imhoff Wastewater treatment – 3,60 m Lid Welding
I lived in an off-grid house for a year in Brandenburg, Germany, where we had to properly treat our own wastewater system. Avoiding organic material from entering the Imhoff Treatment System is a very important step, so we designed a new, round lid with a diameter of 3,6 m. Thin plates with robust I-shaped stabilizators.

Fusion Festival Balcony welding
At Fusion Festival 2023, I welded a small balcony from old metal for a light tower at the Palapa stage while working for the Wanderzirkus collective.

Little guy Chair – my first project
I learned to weld in the shared metal workers workshop “De Loods” in Enschede. I designed a chair for which I also had to learn forging with an acetylene burner, out of recycled concrete pins.
