Can a biodegradable material become the basis for valorizing high-end textile waste?
With SILKI, the answer is yes. The 3D-printed monoblock seat was presented at the Intergraf Design Awards 2026 in Copenhagen (October 14-16) and is made with a Rekrill-based compound, the biomaterial developed by Krillmat and enriched with silk powder obtained from post-industrial textile waste.
The role of Rekrill in the project
For SILKI, Krillmat developed the Rekrill biodegradable base and produced the granules for 3D printing. The silk powder recovered by Pulvera was integrated into this matrix. The result is a material printable in large formats, suitable for a complex design object such as a monoblock seat.
The project demonstrates a key characteristic of Rekrill: its versatility as a matrix.
Rekrill can accommodate fillers from different supply chains—in this case, the textile industry—without losing the compound’s printability or biodegradable nature.

From silk waste to traceable material
SILKI is the result of a supply chain of complementary skills:
- Pulvera, a spin-off of Casati Flock & Fibers, recovered the silk waste, transformed it into powder, and coordinated the entire project.
- Stardust Secured added an invisible optical tracer. This tracer allows for the verification, even in the field, of the presence and quantity of the recycled component in the finished product.
- Krillmat provided Rekrill in granule format for 3D printing.
- Deluxesign handled the printing of the seat.
- The design is by ImagineByCasati by Stefano Casati.
The result is an object that combines recycling, biodegradability, and verifiability. With the digital product passport and new European rules against greenwashing, brands must be able to demonstrate what they claim about materials, not just tell a story.
Why it matters for circular design
For Krillmat, SILKI confirms a precise direction: transforming by-products into high-performance biodegradable materials for 3D printing and manufacturing. The goal is to collaborate with industrial partners who share the same vision of a circular economy.

Intergraf Design Awards 2026
The Intergraf Design Awards are a new initiative of Intergraf 2026, dedicated to creativity, innovation, and excellence in design. This year’s theme is the recycling and recovery of production waste. SILKI was among the selected objects and was exhibited in the main foyer of the event for the entire duration of the manifestation.
