| Technical purpose of product or process | Leca®ton 8–16 round is a high-quality, natural growing medium made from expanded clay, specifically developed for use in hydroponics. It consists of kidney-shaped, round clay granules with a grain size of 8–16 mm. The material is produced by firing natural clay, which is mixed with organic components and expanded at approximately 1150°C in rotary kilns. During this process, the volume of the granules increases by three to four times. Leca®ton 8–16 round is ideal for large containers in hydroponic systems and is suitable for both professional and private use. It provides stable support for plants and promotes the even distribution of water, air, and nutrients. It is refined in Lamstedt, Germany. The substrate meets the requirements for growing media in accordance with the current quality guidelines for expanded clay. The substrate has a bulk density of 350 kg/m³. It is chemically inert, structurally stable, and reusable multiple times. The quality is regularly and independently tested in accordance with the quality standards for expanded clay used as a growing medium. |

| 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. |
