The system boundary of the EPD follows the modular structure in line with EN 15804. This section describes the modules which are contained within the scope of this study. As the scope of the assessment is up to the point at which the lightweight clay aggregate is manufactured modules A1- A4 have been considered in this LCA

General comment
Data quality: Specific data for the product composition are provided by the manufacturer. They represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on registered EPDs according to EN 15804, Ostfold Research databases, ecoinvent and other 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. 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.

Technical purpose
The EPD describes results for production of lightweight expanded clay aggregate, labelled Leca® letklinker, Leca® 10-20, from the factory in Hinge, Denmark. Lightweight expanded clay aggregate is a granular ceramic material made from natural clay (see process description below). The main characteristic of expanded clay is low density combined with high strength. Leca® letklinker is used in lightweight blocks and slabs, insulation fill, water treatment, lightweight fillings and geotechnical fills for thermal and sound insulation purposes. Thus Leca® letklinker is typically hidden in buildings or cast into concrete. The density of Leca® 10-20 is 0.245 tonnes per m³. The thermal conductivity is 0.095 W/mK. Further information or explanatory material may be obtained by contacting Leca Danmark A/S. The water content of the Leca® letklinker is 0% when the Leca® letklinker is produced at Leca Danmark A/S in Hinge. The storage conditions can change the water content of the Leca® letklinker up to 25%. Different waste are recovered in the production process both as fuels as clay additives. See additional Tech info. Leca® 10-20 is produced by using nearby clay and transported by using a conveyer belt to the factory. Negligible amounts of packaging material is used for raw materials and auxiliaries received at Leca Danmark A/S so the potential environmental impacts from packaging is not included. Furthermore the final product Leca® letklinker is sold in bulk, so no packaging is used.
