Zeefier creates textile dyes made entirely from seaweed. Unlike synthetic, petroleum-based colorants, our dyes are biodegradable, chemical-free, and produced without the need for fresh water, farmland, or pesticides.

With seaweed sourced from European farms and side streams, we offer a circular, scalable, and legislation-proof solution for the textile industry. Our dyes are already used on cotton, wool, silk, and linen, delivering a natural colour palette from sand and beige to ocher and green.

Designed as a plug-and-play system for dye-houses and mills, Zeefier enables brands to reduce their footprint while achieving vibrant, durable, and truly sustainable colours.
