Waste Reduction
70% of spent coffee grounds at the source are ignored, ending up in landfill.
Our mission is to solve environmental challenges through smart material design — giving spent coffee grounds a second life inside a premium synthetic leather system.

Rather than treating spent coffee grounds as residue, KUNS gives them a second life — extending material value and creating a distinctive, credible origin story that brands can carry into product.
70% of spent coffee grounds at the source are ignored, ending up in landfill.
Around 4× lower carbon than animal (bovine) leather, and roughly 50% lower overall than traditional leather production.
Biodegrades naturally — beginning within about six months in soil — leaving no toxic legacy or microplastics, unlike PU/PVC which can persist for 500+ years.
Promotes a green economy by giving new life to urban and agricultural waste — turning residue into a valuable material.
KUNS is built on a plant-based foundation made with natural rubber — a crop that supports thousands of smallholder farmers across Thailand. By sourcing it locally, we help sustain rural livelihoods and keep value within the country's own agricultural communities, so every product carries a social benefit alongside its environmental one.
Recovered urban coffee waste, joined with a locally sourced agricultural crop.
