2 Batrec – Mercury waste treatment Center (Hg Center) and Catalyst Recycling Plant (CRP) Yves THELIER,Veolia

3 YVES THELIER Global Director HPI/CPI Veolia PhD, Chemical Engineering, Ecole Centrale Paris, France; Started career as industrial wastewater engineer for chemical industries; Joined Veolia 23 years ago as hazardous waste sales manager; Active in setting up new hazwaste activities in foreign countries in Europe & Asia; Industrial services & waste services for O&G industries for the Veolia specialized subsidiary; Now Global Director O&G Downstream for Veolia Group;

4 Introduction of BATREC  Year of foundation:1989  Turnover in 2013:13,8 Mio Euros.  Employees: 72  Certifications:ISO 9001, ISO and OSHAS  Shareholders:100% Veolia  Business areas:- Battery recycling - Decontamination of Hg-guards - Reactivation of activated carbon - Recycling of Hg waste

5 BATREC – where we are placed

6 Introduction of BATREC – business areas Battery RecyclingHg recycling Reactivation of activated carbonDecontamination of Hg-guards

7 development of volumes from 2006 to 2014  260 t/yearmean value over the last 9 years  containers from AUS - 14 containers from GCC  2014 – expected volumes t Bolivia - 84 t Trinidad

8 origin of the volumes from 2006 to 2014  GCC, Bolivia, Trinidad, Netherlands - spot business (so far)  UK – regular business  Australia - 2 shipments 2008 & 2012

9 Batrec’s Catalyst Recycling business  decontamination of the Hg guards to enable a subsequent Cu recycling 1.waste reception (drums or CHEP bins) 2.sampling 3.storage 4.thermal decontamination 5.sampling & Hg reporting 6.forwarding of the material to Nickelhütte for Cu recovery

10 Batrec’s part in Puracare – sampling

11 Batrec’s part in Puracare – storage  storage for 18 containers  IR detection in front of the boxes

12 Batrec’s part in Puracare – thermal decontamination

13 Batrec’s Catalyst Recycling business – chemical reactions  thermal desorption in furnace (850 °C) HgS  Hg + S  post-combustion chamber (1100 °C) S + O 2  SO 2  lime milk washer SO 2 + CaO + ½ O 2  CaSO 4

14 Batrec’s Catalyst Recycling business – thermal decontamination – charging of catalysts

15 Batrec’s Catalyst Recycling business – thermal decontamination – the furnace

18 Batrec’s part in Puracare – thermal decontamination – post-combustion chamber

19 Batrec’s part in Puracare – thermal decontamination – scrubbers

20 Batrec’s Catalyst Recycling business – thermal decontamination – waste water treatment

21 recent developments – Hg stabilization  motivation for Batrec  offer one hand solution to JM and other customers that require Hg stabilization (no subcontractors needed for stabilization of Hg)  technical approach Hg + S = HgS (red or black) - liquid S + liquid Hg react to HgS - very toxic Hg is transformed into non toxic HgS - produced stone (50 % S, 50 % Hg) can be safely stored in German salt mines

22 recent developments – Hg stabilization  what is the idea behind stabilization to HgS?  the most stable mercury compound  the most insoluble metallic-sulphide compound  the natural mineral form known as cinnabar  alternatives  amalgamation

23 BATREC’s business areas Battery RecyclingHg recycling Reactivation of activated carbon Decontamination of Hg-guards

24 Hg Recycling  Capacity: ca. 300 t/year of waste containing Hg  3 distillation units (2 retorts, 1 rotary kiln)  Treatment of all types of Hg waste  Production of Hg with a purity of %

25 25 examples for Hg containing wastes treated at Batrec  lamps (Hg vapour pressure )  button cells, Hg cells  relays, switches  dental waste (amalgams, centrifuges,…)  thermometers, blood pressure meters  Hg containing chemicals (Hg 2 Cl 2, HgO, HgS, Hg,...)  calomel (solutions) from Cu + Zn metallurgy  concrete & soils & slurries contaminated with Hg  Hg containing solutions  activated carbon, coke and graphite containing Hg ......

27 27 Hg removal from Hg centre off gas  distillation at 600 – 700 °C (Hg vaporises at °C)  distillation under negative pressure to avoid Hg emissions  Hg is removed by a 3 scrubber system  the washers are actively cooled to <5°C in order to condense the Hg  remaining traces of Hg are removed by a final activated carbon filter, filled with S impregnated carbon

28 Hg distillation  2 retorts A500F2000

29  1 rotary kiln for batch operation Hg distillation

31 BATREC’s business areas Battery RecyclingHg recycling Reactivation of activated carbon Decontamination of Hg-guards

32 Adsorbent Recycling Decontamination of Hg guards coming from natural gas production Reactivation of activated carbon  Installation running since November 2011  1.000T capacity for the treatment of catalysts coming from the gas extraction industry („mercury guards“)  3.000T capacity for the reactivation of activated carbon  others wastes containing Hg:  powder carbon.  contaminated soil with Hg and/or Dioxins.  Hg containing waste with organic compounds.

33 Treatment of spent active carbon  Regeneration Treatment at low temperature at 180°C  Reactivation Treatment at high temperature (up to 850°C) that gives back to the carbon its original adsorption capacity  Thermal recycling Carbon’s combustion

34 Reactivation of activated carbon by BATREC  Reactivation of granular active carbon coming from water treatment  Reactivation of extruded active carbon coming from gas treatment plants.  First trials have been made to treat powder active carbon coming the adsorption of suspended pollutants.  During reactivation – Thermal desorption of the pollutants at a temperature of 700 – 750°C – Thermal destruction of the pollutants in the post-combustion chamber. – The original adsorption of the carbon is renewed (iodine index) Added value for customers – Lower purchasing costs for «fresh» carbon (1 – 5 Euros/kg) – Lower disposal treatment costs – Reduction CO 2 emissions
