1 Stena & GRIAG LCD Recycling Safety first

2 The Stena Sphere Three wholly-owned parent companies Sales MEUR, employees (2009) Stena Metall Group MEUR (2008/09) Stena Metall AB Stena AB Stena Sessan AB Concordia Maritime AB (52%) 2

3 Stena Metall AB The leader in recycling Recycling, processing and refinement of metals, paper, plastics, electronics, hazardous waste and other production waste Customized service with total waste management solutions and expertise Advice and environmental training programs International trading in ferrous and non-ferrous metals and oil 3

4 Value-added services within ten business areas Ferrous and Non-Ferrous Metals Recovered paper Hazardous waste WEEE Aluminium Steel Oil Trading Finance Environmental technology 4

5 Stena WEEE The leading electronics recycler in Europe First class processes and solutions for customers, environment and society The most comprehensive and highquality offers in WEEE management, logistics and recycling for manufacturers, manufacturers associations, retailers and businesses 5

6 European locations Stena WEEE Plants and infrastructure Head Office EE Dismantling Cooling Appliances Treatment PMR PRC CRT Sales Office 6

7 GRIAG Glasrecycling AG a Stena Metall subsidary Established employees Europe s leading CRT recycler Outstanding technique for CRT glass Over 15,000,000 picture tubes recycled The process consists of three top level steps Cleaning Separation Upgrading Approved LCD-recycling since

8 Into the future State of the art LCD recycling A closed and automated recycling process Environmentally friendly High recycling rate World wide interest Patents pending 8

9 Mercury Metall and gas Starts to gasify at room temperature Goes through the skin The mercury contained in 3 LCDs is enough to kill a person Strict requirements on emission and air concentrations 9

10 The 35 GRIAG Mechanical LCD Process Cleaning Extraction of mercury Patented method High recovery Low remaining pollution No exposure to workers Separation Separation of mercury free fractions Fe, Aluminium, Plastic, Circuit boards, LCs 10

11 Stena s process actually works! The process is approved Great results in several audits High interest from producers, customers, suppliers and authorities One of the safest industrial LCD processes 11

12 Stena s latest first treatment! Griag can take LCDs directly from the source Approved as first treatment facility (ElektroG) Can take volumes directly from collection points and producers 12

13 Three challenges within LCD recycling Process challenges Logistic challenges Market challenges 13

14 Process 35 challenges Recovering the value Recovery and sorting of FE Aluminium Copper Circuit boards Plastics ABS, PS and PMMA Foils and glass with LC and ITO 14

15 Process challenges The development of a novel technique Patent pending Development led by Stena s R&D department Co-operation with Chalmers University of Technology - Recovery of ITO from solar panels - Recovery of ITO from broken LC glass - Zero Waste project 15

16 Process challenges Achieving fractions free from mercury Legal requirement: 5ppm Hg Customer requirements: 2 ppm Hg Maximum recommended level in fish: 1 ppm Hg The Stena LCD process: <<0.5 ppm Hg 16

17 Process challenges Recovering the mercury safely Mass balances made based on a homogenous stream straight from production Input amount of mercury known A recovery rate of 85% achieved Remaining 15%? The declared amount of Hg in lamps is a maximum value, but from cost reasons the real amount is lower 17

18 Process challenges Making sure no worker is exposed to mercury 18 Manual processes have cost advantages in low scale During dismantling lamps easily break and workers are exposed to mercury. Only continuous measurements in all worker environments guarantee no hazardous exposure Stena s sealed mechanical process controls the mercury Limit value in production environment 100ug/m3. Stena s LCD process has an internal maximum limit of 20ug/m3

19 Logistic challenges Keeping the LCDs intact LCDs are easily broken Transport is preferrably done in boxes or cages, also bigbags is possible 19

20 Market challenges Illegal export Market prices above material value exist. Screens are exported to Pakistan and other non-oecd countries for reuse Such treatment is mostly illegal 20

21 Market challenges Insufficient treatment LCD is a small waste volume Apart from the mercury contents LCDs are similar to small domestic appliances The easiest route is to mix LCDs into the normal waste stream Treatment takes place illegally in normal shredders Mercury is diluted into larger volumes 21

22 Market challenges Incineration Special owens suited for mercury Still a legal alternative Energy recovery instead of recycling, in conflict with the Waste hierarchy defined in Directive 2008/98 EC 22

23 Pros and cons with mechanical LCD treatment + Safe. Workers are not exposed. + Environmentally friendly. Mercury is recovered. + Fast - High investment - Unflexible fractions 23

24 Summary LCD We meet the challenges in our process and logistics We offer a process with high focus on environment and human health Recyclers, producers, authorities and municipalities need to take responsibility and address the market challenges 24
