About the Net2Zero Centre for Doctoral Training

The EPSRC and BBSRC CDT in Negative Emission Technologies for Net Zero (Net2Zero) is a partnership between Aston University (lead), the University of Nottingham, Queen’s University Belfast, and the University of Warwick. The CDT trains future research leaders capable of developing technologies that remove greenhouse gases from the atmosphere and replace fossilâbased systems with sustainable alternatives. Research expertise spans direct air capture, COâ utilisation, biochar, biomass conversion, and BECCS.

As a CDT doctoral researcher, you will:

Build networks across academia, industry, policy, and the third sector.Access stateâofâtheâart facilities and international collaboration opportunities.Undertake training in engineering, communication, entrepreneurship, and business skills.Complete a threeâmonth placement with industry, policymakers, or research collaborators.

Project Overview

This PhD offers an exciting opportunity to develop sustainable, biogenic materials for use as road construction binders. Current road infrastructure depends heavily on petroleumâderived bitumen and nonârenewable aggregates, contributing significantly to carbon emissions, land use, and resource depletion.

Biobased binders are emerging as promising alternatives, offering potential benefits in carbon reduction, durability, and ageing resistance. However, widespread adoption is limited by inconsistent performance data, insufficient understanding of longâterm behaviour, and a lack of standardised testing.

This project will investigate new technological pathways for producing renewable, biogenic road binders that, when used in asphalt mixtures, could transform pavements into longâterm carbon sinks. The research will assess mechanical performance, durability, carbon reduction potential, economic feasibility, and alignment with circularâeconomy principles.

The studentship is mainly funded by the Net2Zero CDT with additional support from Core Additive Technologies Ltd, which will offer opportunities for industrial placement and collaboration.

Applicant Requirements

You should hold, or expect to hold, a Master’s degree with a minimum 60% average and/or a First or Upper Second Class Honours degree (or international equivalent) in materials science, chemistry, chemical engineering, civil engineering, biochemistry, microbiology, or a related field.

The Net2Zero CDT is committed to equality, diversity, and inclusion and particularly encourages applications from groups underrepresented in higher education.
