Sequestration potential of neo-fossils for global chemical industry

Details

Current analyses suggest that replacing traditional plastics with sustainably sourced renewable or regenerative carbon feedstocks could sequester up to 1 Gt of CO₂, potentially exceeding 2.5 Gt by 2050. While technologies for producing plastics from renewable feedstocks and managing single-use plastic consumption are established, the primary need lies in scaling these processes and developing robust end-of-life strategies to minimise carbon leakage from the techno-sphere to the atmosphere, biosphere, and hydrosphere.

This PhD project aims to develop a novel approach known as "neo-fossils," utilising biogenic carbon sources and captured CO₂ to enable carbon sequestration within the techno-sphere. By shifting from the conventional model of importing carbon feedstocks and exporting plastics, this research will focus on leveraging locally sourced biogenic materials and captured CO₂ for plastic production, ultimately contributing to carbon sequestration.

We seek a motivated candidate with a background in chemical engineering, materials science, environmental engineering, or a related field. A strong interest in sustainable development, carbon management, and process engineering is essential. Experience in life cycle analysis, carbon accounting, or renewable feedstock processing will be advantageous.

Entry Requirements:

• A degree in chemistry, chemical engineering, mechanical engineering, environmental engineering, or equivalent (MEng high 2.1 or above; exceptional BEng candidates will also be considered)
• Excellent technical written and verbal communication skills
• Strong time management and ability to meet deadlines
• Ability to work both independently and as part of a team

If English is not your first language then you must have an International English Language Testing System (IELTS) average of 6.5 or above with at least 6.0 in each component, or equivalent.
