With the global demand for high-quality growing media on the rise, growers’ expectations regarding sustainability, product quality and supply security are increasing. Klasmann-Deilmann is meeting these challenges with a clear strategy: maximum deliverability and uncompromising standards throughout the entire value chain.
RHP-certified quality as a standard
As a long-standing member of the Dutch RHP certification scheme, Klasmann-Deilmann ensures that all substrate constituents – including peat, GreenFibre® wood fibre, TerrAktiv® green compost, perlite, coir and bark – comply with strict guidelines on origin, processing and purity. The RHP quality mark guarantees consistently high standards across all production batches and provides reliable crop performance for professional growers worldwide.
Own resources and production: global delivery reliability
Recent years have highlighted the fragility of international supply chains. In response, Klasmann-Deilmann has reinforced its vertically integrated structure with global access to raw materials and decentralised production. This includes its own peat harvesting areas in Lithuania and Latvia, a network of GreenFibre® production sites, a joint venture with Olde Bolhaar Ecoservice B.V. for high-quality composts, and exclusive access to coir materials via Shakti Cocos in India and Sri Lanka.
