| Use advice for data set | Scope: This EPD refers to 1 m of the ACO gravel grid eco and is valid for four product variants (eco grey, eco black, eco S and eco M, without filling material). The product is manufactured in Bdelsdorf, Germany. The Life Cycle Assessment is based on data covering the reference year 2022 (from January to May). System boundary: The type of the EPD is "cradle-to-gate" with options. The modules considered in the Life Cycle Assessment are modules A1-A3, A4, A5, C and D. The declaration for Module B was excluded as the product does not cause any environmental impacts during its service life. Modules A1-A3 The product stage involves raw material supply, the transport of the raw materials and the manufacturing process of injection moulding, including all energy and water consumption during manufacturing. The production of the packaging is also included in module A3. For the environmental impact, the use of green electricity was calculated. The proportion of the electricity demand covered by green electricity in the total electricity demand is 100%. Module A4 This module considers the environmental impact of transport from the production site to the construction site. Module A5 The installation is indicated without the filling material and sand or gravel for the underground preparation, as different quantities are required for the installation depending on the subgrade and the application of the load class. The environmental impacts of the incineration of plastic, cardboard and wood packaging are indicated. Module C1 The deconstruction of the product is done manually, therefore no energy is needed. Module C2 This module includes the transport to waste treatment. Module C3 This module includes the environmental impacts of waste treatment of the product at the end of life. Two scenarios were declared. Module C3/1 100% recycling of the product. Module C3/2 100% incineration of the product and energy recovery. Module C4 No landfilling scenario is considered for the Life Cycle Assessment, so this module is declared zero. Module D According to module C3, two scenarios for module D are declared. The potential benefits for energy recovery from the incineration of packaging material in module A5 are declared in both scenarios. Module D/1 This module includes potential benefits for the recycling of primary polypropylene, but no benefits for recycled polypropylene are declared. Module D/2 This module includes potential benefits from energy recovery of the incineration of the product. | ||
| Technical purpose of product or process | The ACO gravel grid eco can be used in a variety of ways in the design of unsealed outdoor areas with a slope of up to 10%, such as garden paths and terraces, municipal landscaping (e. g. parks, cemeteries), seating areas, courtyard areas, parking spaces, access roads and driveways. The ACO gravel grid is both walkable and in its installed state drivable by bicycle, wheelchair, motorbike and car with a load of up to 300 t/m² (according to DIN EN 1991-1-1). ACO gravel grid eco is approved for vehicles with an axle load of 2.2 t and a max. total weight of 3.5 t. | ||

| General comment on data set | The ACO gravel grid eco (ACO Kiesstabilisierung eco grey and black article no. 281095 and 281092, ACO Self® Kieswabe eco S and M article no. 281090 and 281091) is used for the simultaneous unsealing and stabilisation of gravel surfaces. The ACO gravel grid eco is an ecological outdoor reinforcement system that on the one hand, is used to stabilise gravel and chippings in an environmentally friendly and visually appealing way and, on the other hand, allows rainwater to seep away naturally directly onto the surface of the property. Properly laid, a barrier-free, stable and 100% water-permeable surface is created, that can be walked on and driven over. This prevents ponding. The honeycomb structure of the mats holds the gravel securely in place when, for example, pedestrians, cyclists or cars move over the surface. Wheel tracks of any kind are avoided and less gravel is needed compared to loose stones. An individual design is possible with fine chippings or decorative gravel. The integrated 100% water-permeable geotextile (polypropylene) is untearable connected to the grid. This means that the gravel cannot undermine the product and stays in place. Furthermore, weeds cannot root through the geotextile. The overlap of the geotextile is optimised for laying the ACO gravel grid eco. The honeycombs are made of 100% recycled polypropylene (post-consumer recycled plastic) and the entire product was awarded the "Blue Angel" in 2021. Using a patented injection moulding process, the ACO gravel grid eco is produced by ACO in Germany. For the use and application of the product, the respective national provisions at the place of use apply, in Germany for example the building codes of the federal states and the corresponding national specifications. | ||

| Technology description including background system | The ACO gravel grid eco is produced using an injection moulding process at the production site in Germany, Büdelsdorf. The polypropylene granules are melted in an extruder and the product is formed by injection moulding. During injection moulding, the product is actively cooled. After forming the product is passively cooled. The product is then demoulded and palletised. The ACO Ahlmann SE & Co. KG production site is certified according to the ISO 9001 quality management system. Declared unit: The declared unit is 1 m², with 1.44 kg/m². | ||
