Waste as a Useful Circular Economy Indicator

  1. 1. Session #8: Environment / Waste
 
 
 Waste as a Useful Circular Economy Indicator
 
 Sophie Theys, Bureau Veritas
 Flora Moon, Expressworks
  2. 2. Session #8 Oil and Gas: A Linear Value Chain Slide 2 Adapted from www.quora.com/topic/Natural-Gas
  3. 3. Session #8 Oil and Gas Perspective – Waste Slide 3 •  Fragmented: defined as an inherent material resulting from operations to be eliminated, reused, recycled or recovered including office and commercial activity •  Regulated: hazardous waste components •  Selective: narrow in scope •  Historically waste is not a design consideration and does not indicate good or efficient design
  4. 4. Session #8 How Do We Move from Linear to Circular? Slide 4
  5. 5. Session #8 Oil and Gas Perspective – Perceptions & Barriers for Adopting Circular Practices Slide 5 •  Preference for buying new •  Non standard build of assets - custom equipment •  Risk of reusing material on oil and gas assets –  Health and safety –  Condition of equipment and products –  Insurance concerns •  Few industry precedents •  Environmental remediation and disposal costs can exceed construction cost
  6. 6. Session #8 Actual Barriers to Circular Economy Slide 6 •  Suitability of materials for reuse •  Marketplaces to facilitate reuse and recycling •  Information barriers –  Sectors work in silos •  Organizational/cultural obstacles •  Institutional barriers – Fiscal and regulatory
  7. 7. Session #8 Closing the Loop: Redesign for Reuse, Remanufacturing and Recycling Slide 7 •  Engage value chain stakeholders •  Substitute materials –  eg. in hydraulic fracking, liquified CO2 for water •  Use standard parts •  Apply technologies like “digital twinning” •  Design facilities and equipment for ease of maintenance, upgrade and reuse at FEED - Front End Engineering Design
  8. 8. Session #8 Closing the Loop: Redesign for Reuse, Remanufacturing and Recycling Slide 8 •  Assets are industrial nutrients •  Design for entire value chain synergies, especially handoffs between segments •  Leverage synergies and integrate with other industries that place a value on oil and gas industry outputs •  Steward all resources including human factors, community and the environment
  9. 9. Session #8 Maturity Progression Slide 9 Compliance Adhoc recycling Management tools Closed loop recycling Product/ packaging redesign Culture Synergies developing Eco-Industrial Infrastructure
  10. 10. Session #8 Closing the Loop: Create Road Map Slide 10 •  Identify “low hanging fruit” •  Map where you are in the maturity progression •  Understand capabilities needed to achieve goals •  Begin engaging with / creating “enhanced” value chain •  Create realistic timelines
