This Environmental Product Declaration covers custom-made washbasins and BL-type standard washbasins manufactured by KUMA Romania SRL. These sanitary elements are designed for residential, commercial, and public bathroom installations. The scope of this EPD includes products manufactured from the following composite material families: Kuma Marble, Kuma Granite, Kuma Granulon, and Kuma Grasolit. As the chemical composition and manufacturing processes across these families are highly consistent—with raw material variations of approximately 1.5%—the environmental impact results are presented as an average value per 1 kg of product. This declared unit allows for a precise environmental assessment across the entire range of cast sanitary elements.

KUMA sanitary elements are manufactured using a high-performance composite blend. Although specific aesthetics vary by family, the core composition remains uniform: natural minerals: - approximately 78% marble powder, - Binding Agents: high-quality polyester resins; - Surface Treatment: specialized gelcoats ensuring a non-porous, hygienic finish. The 1.5% variation in components between the four families does not significantly alter the environmental profile, justifying the use of a weighted average for this EPD. Manufacturing and Sustainability The production process takes place at the KUMA facility in Banesti, county Prahova, Romania, following strict sustainability protocols: - Energy Profile: 100% of the electricity used is from renewable sources, with 25% produced internally via an on-site photovoltaic system. - Circular Economy: composite waste is pulverized and reintegrated into the production cycle to manufacture secondary components (e.g., brackets), supporting a zero-waste future objective. - Resource Efficiency: an internal filtration system enables the recirculation of 43% of the water used in technical processes. - Emission Reduction: between 2022 and 2024, KUMA achieved a 31% reduction in CO2 emissions per product through optimized energy and material management. Product Benefits - Longevity & Repairability: the ability to repolish and repair the surface significantly extends the product's life, reducing the need for replacement. - Hygienic Design: the non-porous surface prevents bacterial growth, meeting the highest standards for public and medical environments. - Environmental Transparency: KUMA enables architects and developers to accurately calculate the environmental footprint of specific project configurations for BREEAM or LEED certifications. - Finished products are delivered in protective, recyclable packaging, optimized for weight and transport efficiency. Reference Service Life (RSL) for KUMA composite products is declared as 20 years. This value is based on recognized European benchmarks for sanitary appliances as BBSR (Germany) and BRE Global (UK).
