Selfrag role in Circular Economy

  1. 1. SELFRAG’s contribution to Circular Economy May 21, 2013
  2. 2. Page 2 SELFRAG in a nutshell A new way to break rocks, slags and scrap  SELFRAG History: Swiss company, founded in 2007. Owned by PE firms, management, and institutional/private investors  Principles of Technology: Patented high voltage pulse power technology that fragments or weakens virtually any material. Proven in lab environments and solar silicon manufacturing (continuous 1 ton/h)  Target Market: Continuous 100-1000 ton/h, scalable pre-weakening system for mining and recycling comminution circuits, both greenfield and retrofit. Solution under development  Value Proposition: Significant reduction in comminution, in particular milling, energy consumption and operational costs and increasing efficiency and productivity 19 June 2013
  3. 3. t ~500 ns HV pulse power technology  Based on a HV physical specificity  At short pulse rise time water isolates more than solids  Discharge occurs through solid, causing strong internal shockwaves resulting in selective breakage Industrialized and patented Solid Water 19 June 2013 Page 3 Principles of Technology High voltage pulses to fragment or weaken virtually any material U(t) HV gen HV power supply HV pulse generator Process vessel with electrode in water HV power supply
  4. 4. Page 4 Minimize mass flows; Free-up valuable material at low energy From mine pit, through life cycle, down to landfill: SELFRAG adds value 19 June 2013
  5. 5. 19 June 2013 Step change in mining 1.5% of worldwide electrical energy saving potential SELFRAG long-term vision: a paradigm shift Standard Gravity Primary crusher SELFRAG unit Stirred media mill Thumbler crusher Conventional circuit at mine today Ball mill Floatation Ball mill SAG Primary crusher Pebble circuit Page 5
  6. 6. 19 June 2013 Step change in Urban Mining Save significant transport and processing cost  high CO2 releasing process  high fossil energy usage  transportation impact  transportation impact  landfill impact of waste material currentvalue chain environmentalimpactand related costdrivers CO2 certificates / taxes waste / disposal taxes raw materials extraction cement production construction site destruction site waste disposal  ground water damage  extraction of non- renewable resources  transportation impact aggregate taxes increasing (non-renewable) energy costs reduce / eliminate waste disposal process / costs reduce environmental footprint of the supply chain by recycling materials maintenance reduce material and transportationcosts reduce dependency on supply chain 1 2 3 4 Target SelFrag’s benefits SELFRAG Concrete recovery Extraction of Raw material Cement Production Construction site Demolition LandfillMaintenance • Reduction of CO2 emissions • Reduction of Transport • Reduction pore water damage • Better Energie balance • Increase life time of raw material Benefits: • Premium price for ecological products • Growth with sustainability Costs: • Lower cost for raw construction material • Lower transport costs • Reduced dependency on supplier and increase negociation power. $ Page 6
  7. 7. 19 June 2013 Step change in E-Scrap processing Recover more metals and plastics – less burning and less waste ~ 20% ~80% <10% <3% <3% <95% 100% Printed Circuit Board Furnace / Smelter Shredder SELFRAG Sorting Sorting PCB flakes Components Plastics Components Precious Metals Plastics + Exhaust treatment Shredder Precious Metals WIP Page 7 Furnace / Smelter (less landfill costs)
  8. 8. 19 June 2013 Only 17 % reduction in strength Step change in Composite material recycling Recover and reuse carbon fibers New helicopter fringe made of new carbon fiber material Fringe is fragmented with SELFRAG Fringe is re-built with SELFRAG output fragmented carbon fibers Page 8
  9. 9. 19 June 2013 Business update 9 SELFRAG markets supported by the megatrends Looking for sustainable growth SELFRAG riding the trends • scarcity of non renewable natural resources • Circular economy • increasing energy prices • environmental consciousness (customer and laws) mega-trends • new technology for e-scrap, construction material, high tech composite material recycling • fast growing markets • higher production efficiency • self produced raw material • 50% energy saving • yield increase • eliminate poluting steps
