Ruoco Oy

Ruoco is pioneering regenerative innovation at the intersection of marine restoration and sustainable horticulture. The Baltic Sea and other shallow marine ecosystems are suffering from decades of nutrient runoff—primarily from agriculture and other unsustainable practices. This has led to eutrophication, dead zones, and collapsing coastal ecosystems. At the same time, the horticulture industry continues to rely heavily on single-use plastic containers, contributing to climate change and biodiversity loss. Ruoco addresses both of these urgent challenges with a single breakthrough: transforming excess coastal reed—proliferating due to nutrient overload—into high-value, fully biodegradable seedling containers. This regenerative material innovation removes nutrients from the sea and replaces harmful plastic in horticulture, offering a dual-impact solution that scales. Our value chain model turns an ecological problem into a climate-positive, circular material with strong commercial demand. Backed by successful prototypes and industry interest, Ruoco is redefining what's possible in nutrient capture, plastic reduction, and nature-based materials innovation. Join us in building a healthier future—rooted in the sea, grown on land.
