The Circular Imperative in Oil & Gas
As global demand for reduced carbon emissions intensifies, the oil and gas industry faces increasing pressure to overhaul its operations. The key to accelerating decarbonisation may lie in innovative technologies and reimagining the entire value chain through the lens of circularity.
The circular economy offers a compelling framework for reducing the environmental footprint of the oil and gas sector while unlocking new value streams. By adopting circular principles, companies can minimise waste, optimise resource use, and extend the lifecycle of assets, all contributing to progress towards net-zero goals.
Climbing the R-Ladder: Circular Strategies for Oil & Gas
The R-ladder, or 10R framework, outlines a hierarchy of circular strategies applicable across the oil and gas value chain. From most to least preferable, these strategies include:
- Refuse
- Rethink
- Reduce
- Reuse
- Repair
- Refurbish
- Remanufacture
- Repurpose
- Recycle
- Recover
In this article, we’ll explore three key areas—circular design, industrial symbiosis, and decommissioning—and how they can leverage these strategies to enhance circularity and decarbonisation in oil and gas.
Designing for Circularity: Building Sustainability from the Start
Rethinking Product Design
Applying circular design principles can transform everything from drilling equipment to refinery components. By focusing on circularity, companies can:
- Reduce material use and waste
- Extend product lifespans
- Facilitate easier repair and remanufacturing
- Enable more efficient recycling at end-of-life
Example: Modular Rig Design
Imagine a modular drilling rig designed for easy disassembly and reconfiguration. Components could be swapped out, upgraded, or repurposed as needed, extending the rig’s useful life and reducing the need for entirely new equipment. This approach aligns with the “Rethink” and “Reduce” strategies on the R-ladder.
Sustainable Materials Innovation
The development and use of more sustainable materials can significantly reduce the environmental impact of oil and gas operations. This includes:
- Bio-based lubricants and drilling fluids
- Recycled and recyclable plastics for piping and components
- Advanced alloys designed for durability and recyclability
Example: Biodegradable Drilling Mud
A leading oilfield services company has developed biodegradable drilling mud from plant-based materials. This innovation not only reduces environmental impact but also aligns with the “Rethink” strategy by reimagining a key operational input.
Industrial Symbiosis: Turning Waste into Value
Industrial symbiosis involves creating mutually beneficial relationships between different industries or facilities, where one industry’s waste becomes another’s valuable input. This approach can substantially reduce overall resource consumption and emissions.
Waste Heat Recovery
Oil and gas operations generate significant amounts of waste heat. Nearby industries or communities can capture and utilise this heat through industrial symbiosis.
Example: Refinery-Greenhouse Partnership
A refinery in northern Europe has partnered with a nearby greenhouse complex. The refinery’s waste heat warms the greenhouses, reducing overall energy consumption and emissions for both facilities. This exemplifies the “Repurpose” strategy on the R-ladder.
Carbon Capture and Utilisation (CCU)
CCU technologies can capture CO2 emissions from oil and gas operations and convert them into valuable products, creating a circular carbon economy.
Example: CO2-to-Chemicals
A major petrochemical company has developed a process to convert captured CO2 into high-value chemicals like methanol and ethylene. This not only reduces emissions but also creates new revenue streams, aligning with the “Recycle” and “Recover” strategies.
Decommissioning: Giving New Life to Old Assets
As oil and gas infrastructure reaches the end of its operational life, circular approaches to decommissioning can minimise waste and environmental impact while creating new value.
Reuse and Repurposing
Many components of decommissioned oil and gas assets can find new life in other applications.
Example: Offshore Wind Conversion
Several projects are exploring the conversion of decommissioned offshore oil platforms into foundations for wind turbines. This innovative approach aligns with the “Repurpose” strategy, giving new life to existing infrastructure.
Advanced Recycling
Advanced recycling technologies can recover valuable resources from materials that can’t be directly reused.
Example: Artificial Reefs
Some decommissioned offshore structures are being transformed into artificial reefs, supporting marine ecosystems and biodiversity. This creative repurposing strategy avoids waste and contributes positively to the environment.
The Value Hill: Mapping Circular Opportunities
The Value Hill model provides a useful framework for visualising circular economy opportunities across the product lifecycle in the oil and gas industry:
- Pre-Use (Uphill): Circular design, sustainable material sourcing, modular equipment development
- In-Use (Top): Predictive maintenance, performance optimisation, product-as-service models
- Post-Use (Downhill): Remanufacturing, repurposing, recycling, and energy recovery
By mapping activities to the Value Hill, companies can identify gaps in their circular strategies and uncover potential areas for innovation or collaboration.

The Circular Future of Oil & Gas
As the world transitions towards a low-carbon future, the oil and gas industry must evolve. Embracing circular economy principles offers a powerful pathway to accelerate decarbonisation while unlocking new sources of value and innovation.
Circular strategies can be applied across the entire oil and gas value chain, from rethinking product design to fostering industrial symbiosis and reimagining decommissioning. Companies that climb the R-ladder and leverage the Value Hill framework can systematically identify and implement circular opportunities.
The journey towards a circular, low-carbon oil and gas sector is challenging but essential for long-term viability. With expert guidance from sustainability leaders like Evolveable Consulting, oil and gas companies can navigate this transformation, turning challenges into opportunities and waste into value.
As we look to the future, one thing is clear: circularity isn’t just an environmental imperative—it’s a business imperative. The oil and gas companies that embrace this circular revolution will be best positioned to thrive in the decarbonised economy of tomorrow.
