I began exploring aluminium reuse through discarded offset printing plates. These large sheets, around 0.2 mm thick, are regularly replaced in the printing industry and represent an interesting industrial waste stream. Later, I also directed my attention on beverage cans, which share similar properties and are much more widely available.
Unsafe Origami

Working with aluminium means working with one of the most recycled materials on Earth. According to International Aluminium Institute, it can be recycled again and again without losing its quality, and almost 75% of all the aluminium ever produced is still in use today. This characteristic has helped aluminium replace plastic in many products over the last decades. As a result, aluminium has become a symbol of circularity, waste reduction, and more sustainable consumption.
However, approaching aluminium from a design perspective also means questioning this perception. While aluminium is highly recyclable, recycling still comes with environmental costs. Collecting, transporting, shredding, cleaning, and melting the material all require energy and resource. Aluminium is therefore a good example of a principle often highlighted in environmental discussions: when possible, reuse has a lower impact than recycling.
In design research, Material Driven Design is a methodology used to explore a material and identify applications that best match its properties. Since I was already familiar with aluminium and its characteristics, I decided to shift the focus from the material to the process itself. I approached the project through what I called Process Driven Design (PDD).
I started exploring aluminium sheets through the folding process. This eventually led me to discover modular origami: structures generated by repeating and combining a single unit into increasingly complex forms.
I focused my attention on developing one folding unit. Moving from paper to aluminium introduced both advantages and challenges. Aluminium is stiffer than paper, making folds more stable and durable. At the same time, it is harder to fold and tends to crack if bent repeatedly.
To adapt the process to the material, I modified the folding technique and developed a small toolkit to improve precision and consistency. This allowed me to produce units that met the quality standards required for larger assemblies.
Applying the folding process to beverage cans reveals how accessible and reproducible it can be. Many people consume drinks sold in aluminium cans, and a single large can can provide enough material to create several Unsafe Origami units, each carrying its own unique colours and graphics.
These units can be combined in many different ways. They can be assembled into small formal explorations or used to create larger and more complex structures. The required tools are simple, the material is widely available, and the possibilities are open-ended.
