PORCELANOSA, S.A.U.
With the aim of offering new materials and technologies to improve quality, enhance energy efficiency, and reduce environmental impact, it has registered DAPcons®.NTe.239.
Glazed ceramic tiles (BIla classification according to UNE-EN 14411:2016)., The Glazed ceramic product includes different glazed ceramic product families from absorption group BIIa (formed by dry pressing with water absorption 3% < WA ≤ 6%). The results presented in this declaration refer to an average product that represents various series. The average product has been calculated based on the weight per square meter of the different series included and weighted according to the production during the studied period. The formats covered by this declaration have a thickness ranging from 8.5 mm (20.63 kg/m²) to 10.3 mm (22.26 kg/m²), with an average weight of 21.66 kg/m².
ReMa-Ingenieria, S.L., an affiliated member of the DAPconstrucción® Program, was responsible for preparing these DAPcons®, which were subsequently verified by DAVID PORRAS MELENDEZ. They are valid until 21/07/2030 and are based on the Product Category Rules UNE-EN 17160:2019 Product category rules for ceramic tiles. This study was carried out using the LCA tool SimaPro 9.6.0.1 by PRé Sustainability, which has been developed based on the UNE-EN ISO 14040–14044 standards, and using the Ecoinvent v3.10 (2023) database. This LCA follows a “cradle-to-grave” approach, encompassing the product manufacturing, construction, use, and end-of-life stages. Specific data from PORCELANOSA’s production plants in Villarreal (Castellón, Spain) for the year 2022 were used to inventory the manufacturing stage. The study is based on: – UNE-EN 15804:2012+A2:2020/AC:2021 (and its corrigendum), – UNE-EN 17160:2019, Product Category Rules (PCRs) for ceramic tiles, and follows the principles of modularity and the “polluter pays” approach. Allocation procedures: – Internal recycled materials (such as chamotte and unfired scraps) enter the process with no environmental burden; they are considered to have reached “end-of-waste” status upon entering the atomization plant. The recycling process is accounted for as if they were conventional raw materials. – Recyclable waste is considered to reach the end-of-waste status at the gate of the waste management facility → only transportation impacts are included. – Co-products from stages A1–A3 are not included in Module D. – For external recycled materials (e.g., chamotte), as it is a waste material derived from fired ceramic tiles, an economic allocation is applied. A value is assigned to the chamotte based on the average market price of ceramic tiles and the price of chamotte itself. Based on this price ratio, a proportional share of the environmental burden of ceramic tile production is attributed to the chamotte. Production at plants: Allocation methods – Clay-based materials: Allocated by plant according to atomizer production and destination. Allocated by product family based on kilograms produced. Energy: – Natural gas: Allocated by mass, except for atomizers (allocation based on the destination of the atomized material). – Electricity: Allocated proportionally to the square meters produced. – Diesel, alumina balls, packaging: Allocated proportionally to the kilograms of production. – Water: Allocated proportionally to the square meters produced. Emissions: – CO₂ from combustion and other parameters: Allocated according to natural gas consumption per product. – CO₂ from the process (decarbonation): Allocated proportionally to the kilograms produced of the corresponding ceramic body. – Effluents and waste: Allocated proportionally to the kilograms produced. – Cogeneration: Part of the electricity generated is consumed internally; the surplus sold is considered an avoided burden (accounted for only in Module A3, not in Module D).
The DAPconstrucción® Program was established in 2008 with the objective of bringing together manufacturing companies that wish to advance the analysis of the environmental impacts of their products and commit to environmental improvement.
