Green Gravels OÜ

What Green Gravels OÜ does

Green Gravels OÜ is an Estonian manufacturer that produces VitriCel, a foam glass gravel aggregate, from recycled container and flat glass. The company manufactures at a dedicated plant in Järvakandi, Estonia, and is headquartered in Soodevahe. Its single product is positioned for construction, infrastructure, and landscaping end-uses, including road sub-base, embankments, building insulation and pipe insulation, where it competes with expanded clay, lightweight aggregate, and cellular glass products.

The production process mills recycled glass to a powder of approximately 0.1 mm, mixes it with a foaming agent, and heats the mixture to roughly 900 °C. The material expands to about five times its original volume, is cooled, and is broken into graded pieces of approximately 60 mm. The plant has a stated capacity to recycle up to 11,000 tonnes of glass per year, yielding up to 60,000 m³ of foam glass gravel per year. VitriCel carries an A1 fire-classification and an M1 emissions rating, and is listed in the Nordic Ecolabel database, which supports specification in green-building projects in the Nordics and Baltics.

Green Gravels sells through a hybrid go-to-market. In Estonia, distribution is handled by building-materials retailers ESPAK AS and Puumarket AS, which stock VitriCel in bulk and in 1.5 m³ and 2.8 m³ big-bag SKUs. In Finland, Sweden, Denmark, and Latvia the company runs direct sales, with historical reach into Russia. To date, growth has been substantially funded by EU public money — primarily an ERDF grant of approximately €3.9 million for the Järvakandi factory, a Cohesion Fund grant of approximately €300,944.50 in 2023 for resource efficiency, and a NextGenerationEU grant of approximately €100,000 in 2024 for raw-material security and export-grade quality. With disclosed headcount in the 1-10 range and no published revenue, Green Gravels remains a small, capital-intensive, single-product industrial operator in the scaling phase.
