Abstract
Unilever has a longstanding strategic partnership with the University of Liverpool. To date, the focus has been on cocreating shared scientific capability. Over £100M has been co-invested since 2006 to drive knowledge leadership, improved productivity, reduced time to market, and high-value IP portfolios. This new partnership will address how to achieve the UK Government's 2019 target of Net-Zero by 2050, through disruptive innovation in the current chemical supply chain. It is a fundamental scientific step-change over our current collaboration, motivated by a shared commitment to achieve Net-Zero through new, targeted, co-developed chemical science.
The majority of chemicals currently used in consumer products (such as shampoo & laundry liquids) are derived from virgin petrochemicals, many are not biodegradable. Unilever has a strategic target to replace its current formulation ingredients with non-petroleum sourced materials designed for environmental degradation. Currently, its suppliers cannot supply this type of material in sufficient quantity. This Prosperity Partnership will address this, through its ambitious vision to co-create the science base for a radically transformed sustainable consumer products materials platform in a Net-Zero world.
The project has four tightly integrated technical work-packages. They will deliver a versatile suite of catalyst materials for sustainable production of surfactants, monomers, and polymers from waste, new tools for measuring and predicting polymer bio-degradability, state-of-the-art predictive digital methods, and high-throughput lab techniques. A dedicated work-package will undertake a detailed consideration of the wider social, ecological and economic consequences of the science programme, and how the outputs of the chemistry research can be translated into a wider Innovation Ecosystem.
The project will deliver a wide range of outcomes and impacts including new scientific platforms for designing and inventing renewable and bio-degradable materials, and new routes to make these materials. This fundamental research will greatly benefit the UK and Global scientific communities in the development of Net-Zero aligned chemistries.
Our 5Ps for PROSPERITY framework will be used to deliver key outcomes.
PEOPLE: High calibre research and innovation staff, with the ability to create and deploy new knowledge, are the human capital we will need to deliver Net-Zero innovation. The level of ambition of the project and the translational research environment of the Materials Innovation Factory will provide a unique training and professional development opportunity for students, researchers, Unilever staff, and other company staff involved in the project and wider ecosystem.
PARTNERSHIPS: new knowledge-based partnerships will be used to orchestrate an Innovation Ecosystem (TRL 1-9) that can maximise value creation and exploitation from the project.
PATENTS: Numerous high-value inventions, with wide applicability, including outside Unilever's core interests, will be used to galvanise investors into backing these innovative ideas with expertise and capital. A range of investment routes will be explored to exploit high-value IP (e.g. Unilever patent filings, UoL in-house filing/commercialisation, partnerships with commercial IP development teams).
PLATFORMS: Digital platforms package and exploit scientific know-how, underpin partnerships, monetise and exploit clever ideas. We will create new digital platforms to exploit project insights. Fully engineered platforms based on new digital assets from this project will be the focus of further funding and investment.
PUBLICATIONS: Seminal academic papers in high quality peer-reviewed journals.
The project is aligned to Global, National, and Regional agendas including: UN Sustainable Development Goals, UK Industrial Strategy, UK Chemistry Council Strategy, EPSRC delivery plan, and Liverpool City Region Local Industrial Strategy.

Description | Progress towards new synthesis platforms has been made with catalytic approaches for synthesis of long chain alcohols and monomers established. For example, a high-throughput synthesis and structural characterisation protocol has been developed to screen libraries of catalysts for long-chain alcohol synthesis from waste and to investigate the effect of components (supports and promotors). The synthesis of monomers from waste resources has identified new catalytic platforms and optimised application conditions using data-driven methodology. Alternative catalyst synthesis techniques have been developed. Future monomer targets have been defined by the interaction across the partners, combining catalytic platform capability with readiness for synthesis of appropriately functional polymers in the selection criteria. Over 50 new polymer candidates have been prepared, enabled by new earth-abundant catalysts, and evaluated for biodegradation properties. Work on data-driven models that relate material composition, structure properties, and biodegradability has generated an in silico Design of Experiments to integrate work packages, with further work underway. Automated polymer characterisation modules are being developed to increase polymer screening throughput, which will be integrated with existing synthesis platforms. An automated proxy biodegradation protocol has been developed and implemented to accelerate evaluation of biodegradability. A wide range of optimised workflows have been implemented. Focus is on 'design-make-evaluate-model loops' using workflow engineering to optimise efficiency (in some cases automated). Support for technology development investments to move candidate molecules (catalysts, monomers, polymers) to higher TRL is progressing, such as Flue2Chem investment by Unilever and a bid for a Sustainable Manufacturing Hub involving the project team. |
Exploitation Route | By application of the materials and catalysts and processes developed in the synthesis of molecules and polymers from waste starting materials and the integration of these outcomes into formulations and products, and by assessment of the processes developed in considering technology options for future consumer products. In the accelerated assessment of the biodegradeability of polymers. In the development of automated workflows and in the assessment of experimental data and improvement of experimental design using digital methods. |

Description | The project aim is to enable the use of sustainable carbon for consumer products. In addition to the technical insights that project research is providing to enable decisions about future commercial decisions regarding supply chains, carbon sources and viable products, the project is engaged with the wider community to raise the profile of the importance of sustainable carbon in the chemical industry. Members of the project team formed part of the Royal Society working group which released the 'Net zero aviation fuels: resource requirements and environmental impacts' policy briefing in February 2023 and met with considerable media attention, as it highlighted that at present there are no options at scale other than current fossil fuel technologies, emphasising the urgent need for research and innovation as well as the establishment of suitable supply chains. As the manufacture of fuels and of chemicals is at present closely interconnected, and there will be sector competition for carbon sources in future, this outcome is significant for the sustainable chemicals manufacturing area addressed by the project. Further, the team were part of the organising committee for the Royal Society event 'Green carbon for the chemical industry of the future', held in December 2023 in London. Our industry lead presented a talk titled 'Why we need non-fossil carbon for the chemical industry: The hidden footprint of consumer goods' at the event. The meeting was attended by the Chief Scientific Advisor Department of Energy Security and Net Zero, who was a member of the panel in the final discussion session. Project team members are involved in preparing a Royal Society policy briefing on carbon sources for a net-zero chemicals industry, engaging with multiple stakeholders to ensure a coherent assessment of the options is available. In September 2023, project team members jointly authored a report with experts in Environmental economics, led by Prof. Cameron Hepburn, and Unilever: 'Cleaning up Cleaning: Policy and stakeholder interventions to put household formulations on a pathway to net zero', K. A. Collett, E. Fry, S. Griggs, C. Hepburn, G. Rosetto, N. Schroeder, A. Sen, C. Williams; Oxford Smith School. The report is a combined technical, economic and policy analysis of the market for bio-derived polymers and chemicals for liquid formulations and calls for national strategies for sustainable bio-carbon feedstock to enable a pathway to net zero for these products. Further, the project lead investigators were invited as 1 of 5 Prosperity Partnerships, to present at the EPSRC Prosperity Showcase event in May 2023. The audience included representatives from the 47 current Prosperity Partnerships, chief scientific advisors, representatives from the Department of Science, Innovation and Technology, EPSRC staff, and the chair of UKRI. In addition to the extensive networking on the day, the response at this event highlights an opportunity to raise the profile of the challenge addressed by the project with key opinion formers in the UK research landscape. |

Impact | The report looked at four alternative fuels: hydrogen, ammonia, synthetic fuels (efuels) and biofuels, and examines each option against: equivalent resources that would be required for that option to replace fossil jet fuel; life cycle analysis and non-CO2 environmental impacts; likely costs; and modification or replacements needed to implement the option. It is evident that all alternative fuel options have advantages and challenges and there is no single simple answer to decarbonising aviation. The main conclusions of the report are: - Availability and accessibility of sustainable feedstock for all options is a key challenge. - Further R&D will be needed in the development of the efficient production, storage and use of green hydrogen, ammonia and efuels. - Further development of LCAs of all alternative aviation fuels is required which will be critical in clarifying emissions across the entire cycle and highlighting key mitigation opportunities. - R&D is required to understand and mitigate the non-CO2 climate impacts of all the alternative fuel options. - A holistic approach with regards to alternative fuel and engine and airframe development will be needed. - Considerations will have to be made on handling multiple technologies both in the airport and aircraft. - Staff and crew will need specialised training on handling alternative fuels, and the public will need to be informed about the relevant safety concerns within the airport and aircraft. |

PI Contribution | Unilever partnered with Econic in the BEIS Carbon Capture, Usage and Storage (CCUS) Innovation 2.0 competition to secure £1 million for the project. |
Collaborator Contribution | There is increasing imperative and demand for fast moving consumer goods, like household cleaning products, to be made sustainably, at price. Econic offers an innovative solution for surfactants producers, an integral component of cleaning products, to utilise captured waste carbon dioxide as a raw material in their production processes. The use of Econic's catalyst and process technology in the production of non-ionic surfactants allows captured waste CO2 to replace up to 40 wt% of traditional fossil fuel based and palm oil derived raw materials in a process that can be retrofitted onto existing production plants. |
Impact | Ongoing. This project is enabling the creation of a robust decision support package for technology development investments that move candidate molecules (catalysts, monomers, polymers) to higher TRL. |
