| Use advice for data set | Scope: This ARGE EPD covers padlocks and padlock fittings operated by means of a key, and used for securing buildings. The reference product used to calculate the impact this product group has on the environment is a padlock composed primarily of steel, zinc-based alloy and brass. This product is the only one assessed for this EPD and serves as reference to cover all products within this family. This product has been determined in accordance with ARGE and the market share as the most representative product of the family. System boundary: This type of EPD covers “cradle-to-grave” requirements. The analysis of the product life cycle includes the production and transport of the raw materials, manufacture of the product and the packaging materials, which are declared in modules A1-A3. Losses during production are considered as waste and are sent for recycling. No recycling processes are taken into account except transport and an electricity consumption for grinding the metals. When recycled metals are used as raw material, only their transformation process is taken into account: not the extraction of the raw material. A4 module represents the transport of the finished product to the installation site. There is no waste associated with the installation of the product. The A5 module therefore represents only the disposal of the product packaging. Re-cycling requirements considered for this study, have no inputs or outputs in stages B1-B7. The End-of-Life (EoL) stages are also considered. The transportation to the EoL disposal site is taken into account in module C2. Module C4 covers the disposal of the padlocks. Module C3 covers the recycling of the individual elements according to European averages, with the remaining waste divided between incineration and landfill. The same assumption as for waste to recycling in A3 is used here. For end of life modules (C1 to C4) the system boundaries from the /XP P01-064/CN/ standard have been followed, see annex H.2 and H.6 of the standard document cited previously for figures and further details. In practice, the end-of-life has been modelled as follows: - When material is sent for recycling, generic transport and electric consumption of a shredder is taken into account (corresponding to the process “Grinding, metals”). Only then, is the material considered to have attained the “end-of-waste” state. - Each type of waste is modelled as transport to the treatment site with a distance of 30 km (source: /FD P01-015/). Parts sent for recycling include an electricity consumption (grinding) and a flow (“Materials for recycling, unspecified”). Four scenarios for the end-of-life of the products have been declared for this EPD: - 1 100% of the product going to landfill - 2 100% of the product going to incineration - 3 100% of the product going to recycling - 4 mixed scenario consisting of the previous three scenarios, values depend on of the amount of waste going to recycling. Module D has not been declared. |

| Technology description including background system | The production of a padlock normally follows a 3 step procedure: 1. Preparation of semi-finished components (as indicated in 2.6). This step might include a surface treatment on the factory site or by an external manufacturer. 2. Preassembly of assembly modules (on-site factory) 3. Final assembly (on-site factory) Individual parts of the padlock are assembled manually. Technical data: Ideally, products should comply with a suitable technical specification. /EN 12320/ is an example of such a specification and some products will comply with this. The relevant grading structure is shown in the following table Declared unit: The declared unit for all products covered by ARGE EPD is 1 kg (of product). Since individual products will rarely weigh exactly 1 kg it is necessary to establish the exact weight of the product then use this as a correction factor to determine the true values for 1 kg of product in the tables (Section 5). |
