Kiaro

Can liquid wood feel premium?

Back to work

A six-piece kitchenware collection in Arboblend, a lignin-based biocomposite. A bachelor thesis with Vaida Staberg, developed together with Yellon.

RoleShared project. I led CAD, form development and rendering.

The challenge

Making liquid wood read as premium.

Arboblend costs more than ordinary plastic, so it lands in a higher price bracket. But people don't read biodegradable material as premium. They park it somewhere neutral, and when they buy, function matters more than sustainability. The problem was perception, not the material.

Process

Same object, four forms.

Double Diamond, but material-driven: the material set the direction, not a user problem. Broad sketching came first. Then I built four CAD versions of the same salad servers — identical base dimensions, only the radii, taper and handle profile changed — and a validation survey ranked them on perceived premium. Concept C sat at the top, though the margins were small and shifted with age and gender. In parallel we sourced Arboblend directly from Tecnaro, specified for food contact, dishwasher use and low shrinkage, and 3D-printed prototypes to get the material in hand.

The form language

Five principles.

  1. 01Reduced form
  2. 02Balanced proportions
  3. 03Low visual complexity
  4. 04Matte, lightly textured surface
  5. 05Material honesty
The collection

Six pieces.

Kitchen tools, storage and serving — the categories where the study showed people trust the material most.

Reflection

Sustainability alone didn't make Kiaro read as premium. The form did. Small changes in radii and proportion moved how premium a product felt, even with the material and function held constant. And premium isn't universal, it depends on who's looking.
