1 General information KME Germany GmbH & Co. KG Programme holder IBU - Institut Bauen und Umwelt e.V. Rheinufer 108 D-53639 Konigswinter Declaration number EPD-KME-2012321-E This Declaration is based on the Product Category Rules: Building metals, 06-2011 (PCR tested and approved by the independent expert committee [SVA]) TECU® copper sheets and strips (TECU® Bronze, TECU® Gold) KME Germany GmbH & Co. KG Owner of the Declaration KME Germany GmbH & Co. KG Kolsterstrasse 29 49074 Osnabruck Declared product / Declared unit Sheets made of copper. The declared functional unit is 1 kg of copper sheets...

2.6 Base materials / Ancillary materials TECU® Bronze consists to 3,5-4,5 % of Tin and of Cu-DHP according to DIN EN 1172, i.e. oxygen-free phosphorus de-oxidised copper with limited residual phosphorus. TECU® Gold consists to 4-6 % of Aluminium, 0,3 -1,5 % tin, 4-6% zinc and Cu-DHP according to DIN EN 1172 .e. oxygen-free phosphorus de-oxidised copper with limited residual phosphorus. Only internal and external scrap is used for TECU® alloys. Primary copper cathode is not used. Small amounts of Al, ZN and Sn are added. Rolling oil-emulsion: 0.544 g/kg Cu highly refined mineral oil, organic...

The reusable palettes can be reused. Not reused packing material is incinerated 2.11 Condition of use TECU® Bonze is an alloy consisting of copper and tin. The ingredients are stated in 2.6. The changes in colour of the surface are caused by: Further weathering causes the oxide layer to gradually grow; the thicker and denser it gets, the slower this growth becomes. Green Patina: depending on the building geometry and the local climate, causes the formation of the green patina that is typical for copper. 2.12 Environment and health during use There will be no affects to health if the TECU® Eco products...

3.4 Cut-off criteria All material flows that enter the system and are over 1 % of their entire mass or contribute more than 1 % to the primary energy consumption, were taken into consideration on the input page. All material flows that exit the system and whose environmental impact makes up more than 1 % of the total impact in an impact category considered, are covered on the output page. 3.5 Background data In order to model the life cycle for the production and recycling of the copper strips, the GaBi 5 software system developed by PE International was used /Fehler!

5 LCA: Results The following tabels show the results oft the LCA Environmental Impact Assessment, the Ressource Use, the waste-flows and other output-flows of 1 kg copper sheet produced by the KME Germany GmbH & Co. KG. The result of the environmental impact assessment is only a relative statement. It gives noch Information about endpoints of the impact assessment, if threshold Values are exceeded, safety margins or risiks. PRODUCT STAGE CONSTRUCTION PROCESS STAGE BENEFITS AND LOADS BEYOND THE SYSTEM BOUNDARYS HWD = Hazardous waste disposed; NHWD = Non hazardous waste disposed; RWD = Radioactive...

Modul D contains a burden for TECU Bronze and ® TECU Gold. This is is caused by the additional need of primrary material, because of the collection loss in the end-of-life phase. ® In case of the product TECU Bronze, for almost all Impact categories the generation of Energy is the dominant process. In all assest Impact categories generation of energy has a significant contribution. To a lesser extent, the provision of thermal energy from natural gas and the provision of Tin have noticeable contribution to Acidification, Euthropication and the Photochemical Ozone Creating Potential. ADPElements...
