| Technical purpose of product or process | Light expanded clay aggregate is a granular ceramic material made from natural clay. When fired in rotary kilns at a temperature of approximately 1150 °C, the clay increases in volume to 5 times its original volume. The output lightweight expanded aggregate has sizes ranging from 0-20 mm, then it is dried and sieved through a system of sieves. Depending on the application, an optimal aggregate mixture is prepared and distributed loose or in bags. The EPD describes results for production of lightweight expanded clay Leca® KERAMZYT 8/10-20 mm. The EPD shall also be used for all products with the same declared bulk density delivered in bulk: Leca®KERAMZYT 8/10-20r, Leca®KERAMZYT 8/10-20Rx ,Leca® KERAMZYT geotechniczny 8/10-20 RX, Leca® KERAMZYT 10-20 R. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804+A2. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
