Spent coffee-ground material system
Where spent coffee grounds become premium leather.
KUNS is an innovative breakthrough that repurposes spent coffee grounds — a common urban waste — transforming them into a refined synthetic leather made for polished product applications.
KEY FEATURES
Engineered for integration, strength, and responsibility.
Three properties set KUNS apart from both traditional leather and conventional synthetics.
Seamless Integration
Microscopic analysis shows that the material’s components blend well together, requiring only a small amount of natural rubber binder -without requiring the coating chemical
Multi-directional Strength
Unlike traditional leather, KUNS has superior tensile strength in all directions (isotropic), making it easier to design products that withstand stress from every angle.
Eco-Friendly Alternative
A sustainable substitute for genuine leather — which relies on intensive animal farming and heavy chemical use — and for plastic-based synthetic leathers.
COLORWAYS
Available in three tones — inspired by the roast.
The current range offers three refined, true-to-material colours. Additional tones can be explored with partners during development.
BLONDE ROAST
Amber
#8A6A3A
A warm, golden-brown tone — the lightest of the current range.
MEDIUM ROAST
Coffee
#5A3E2B
A balanced red-brown with the warmth of freshly roasted coffee.
DARK ROAST
Espresso
#2F231B
A deep, near-black brown — refined, quiet, and composed.
WHY IT MATTERS
A responsible material, backed by real science.
- Repurposes a common urban waste into a high-value material.
- A plant-based alternative — no animal hides, no petroleum PU or PVC.
- Warm brown tones come from the coffee's own natural pigment.
