1. Session #8: Environment / Waste
Waste as a Useful Circular Economy
Indicator
Sophie Theys, Bureau Veritas
Flora Moon, Expressworks

2. Session #8
Oil and Gas: A Linear Value Chain
Slide 2
Adapted from www.quora.com/topic/Natural-Gas

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. Session #8
How Do We Move from Linear to Circular?
Slide 4

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. 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. 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. 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

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
