2 Overview 1. Introduction 2. Production 3. Uses of the mobile phone 4. Waste manegement and recycling 5. New Life Cycle 6. Conclution [1] 2

3 Introduction - First mention of mobile phone: 1920 (AT&T) - First mobile phone: 1983 (Moterola) ,93 Mio. users in Germany ,41 Mio. users in Germany ,44 Mio. users in Germany Generation dial plate Generation Botton phone Generation mobilphone Generation Smartphone New Innovation Begin of digital technology Begin of Internet, Social Media High-performance Hardware [2] [3] [4] [1] 3

4 Introduction Life Cycle Ecological backpack - Resource input in a product - abiotic, biotic raw materials, earthwork, water & air - Resource intensity is underestimated - How heavy is a mobile phone, seen from the perspective of ecological backpack? 4

5 Production raw material extraction Mobile phone ~ 60 different substances % plastic % different metals % glass & ceramic Tantalum 0,5% Silver 0,5% Copper 15% Other 15% Plastic 50% Mining - Asia, South America und Africa Cobalt, Lithium 4% Glass, Ceramic 15% - Bad conditions - Great demand Ecological backpack: raw material extraction = 35,4 kg 5

6 Production - Manufacturing Global production - Largest producers are Samsung, Nokia, Apple, LG und ZTE - Mostly emerging and developing countries - Biggest producer is China E.g. conductor board - Complex and extensive - Raw materials: plastic, copper, tin, zinc, silver, silicium, tantalum, iron, ceramic, platinum, palladium, titan, chrome etc. [5] Ecological backpack: manufacturing = 8,2 kg 6

7 Production - Trends - Ecologically friendly production (Fairphone) - Decrease in the harmful impact - Better production - Resource efficiency - Better designs (miniaturization) - New development - Null-Energie-Handy energy source is human body 7

8 Uses of the mobile phone - Development - Many application possibilities - Shorter useful life - Price reduction - High energy consumption - Application areas INSTANT MASSAGING WETTER SOZIALE NETZWERKE SPIELE NACHRICHTEN MUSIK HÖREN SUCHE SPORT FOTOS/VIDEOS 14,7% 14,1% 11,6% 10,2% 8,5% 7,5% 26,7% 26,1% 32,7% 35,4% [6] Ecological backpack: uses = 31,6 kg 8

9 Uses - Trends - Wearables (Smartwatches) - Alternative operating systems (Windows phone) - 64-Bit processors - New displays - 4k- cameras - Smartphone-car interaction - 9

10 Disposal - Recycling - Different approaches - Professional disposal - Give away mobile phones - Sale of used mobile phones Give Away 19% Hand over 5% Garbage 2% Retain 30% - Importance - Save energy und resources - Longer expected life cycle duration Return 15% Resale 29% [7] Ecological backpack: Disposal = 0,1 kg 10

11 Disposal - Recycling Annually, 75 million mobile phones are thrown away - Big environmental impact - Important raw material are lost Recovery of resources 1. Collecting point, disposal firm, producer, 2. Enquire about the possibility of the reuse 3. First aid treatment -> sorting and separating of components 4. Disassambly, etc. 5. Recycling and preperation of raw materials (smelting process [Hüttenprozess]) 6. Disposal of waste 11

12 New Life Cycle New Devices New Users New Use Re-Use Design Manufacturing Uses Disposal Evaluation Raw material recovery Recycling Sorting Material recovery Disposal, Dumping, Sale, 12

13 Conclusion Life cycle of mobile phone - Complex - High material consumption - 47 % - Material extraction - 42 % - Uses - 11 % - Manufacturing - 0,1 % - Disposal Trends - Friendly production process - New designs (architecture) - New laws 13
