What we're looking for

This opportunity aims to fund interdisciplinary research to support a more sustainable overall plastics system and a move towards a circular plastics economy through developments in:

  • biological sciences
  • biotechnology
  • engineering
  • information and communications technology (ICT)
  • mathematical sciences
  • physical sciences

Plastics are an essential material within advanced societies. However, their extraction and production can have damaging impacts. Their low cost has led to a culture of disposal following limited use and their durability can be problematic at the end of their use-life.

Aligning to UK Research and Innovation’s (UKRI) strategic theme of ‘building a greener future’ and the UK’s net zero research and innovation framework, EPSRC and BBSRC are looking to support research into delivering a circular economy for plastics and harness the significant positive economic and environmental impacts it will enable.

The opportunity will directly deliver against EPSRC’s engineering net zero priority ambitions to collaborate across UKRI to deliver whole systems approaches and solutions to:

  • reduce resource used
  • eliminate pollution
  • deliver a sustainable zero carbon future

EPSRC and BBSRC welcome proposals from across the plastics research community. The whole of the product lifecycle is in scope from extraction and novel and conventional production, to maximising the longevity and value achieved while in use and finally to recycling and recovery at the end of life.

Interdisciplinary approach

We want to see interdisciplinary project proposals that commence by addressing a novel challenge relevant to delivering a more sustainable and, where appropriate, circular plastics system in one or more of the following areas:

  • bioscience
  • biotechnology
  • engineering
  • ICT
  • mathematical sciences
  • physical sciences

Plastics research can fall within the remit of any of the research councils and is often interdisciplinary by necessity. For this opportunity proposals must lie primarily within EPSRC’s or BBSRC’s remit, or both. Interdisciplinary projects that in part fall within the remit of other councils are welcome and encouraged. Participation by researchers from other disciplines will be eligible for funding.

Where relevant EPSRC and BBSRC will work with other councils to ensure a representative range of subject expertise is involved in the peer review process. However please note that proposals deemed to have a majority remit within another UKRI council will be rejected. EPSRC and BBSRC reserve the right to make such remit decisions without reference to peer review.

What we expect to see in proposals

Proposals should address research challenges that support a more sustainable overall plastics system and where appropriate, a circular plastics economy. Applications that look towards creating tighter loops and maximising value retention are particularly encouraged.

Your proposal should:

  • be adventurous and ambitious with the potential for high impact
  • address real-world challenges
  • be developed in partnership with relevant stakeholders such as industry or government. Proposals which connect and contribute to local innovation priorities are particularly welcomed

Proposals must present a credible potential translation pathway for the research outputs, demonstrating how the project will likely help deliver a sustainable plastics future through the practical application of the research.

You should consider and engage with wider stakeholders, including policymakers and where appropriate, the public.

The UK Circular Plastics Network (CPN) is willing to suggest relevant potential industrial partners wherever possible. To that end, you should approach CPN to explore possible collaborative opportunities as early as possible.

Before applying, you should:

  • read the background for this opportunity in the ‘additional info’ section
  • consider the broader context, sectors and plastics system or systems your proposed research outcomes sit within

Research challenges

This opportunity is open to any project addressing a research challenge related to accelerating the transition to a circular plastics economy. EPSRC and BBSRC particularly welcome proposals addressing the following priority areas where significant challenges remain:

  • tighter loops of circularity by designing for reuse, disassembly, remanufacture (from molecular to whole product levels), and repair including in-situ (self-healing)
  • novel approaches to recycling of the approximately 50 to 55% of plastics which currently are not recovered at the end of life
  • recovery and reuse of plastics currently lost to the environment, in particular micro- and nanoparticles and fibres including the use of bioremediation approaches
  • strategies for managing the impact of additives in plastics on recycling of plastic products. Additives can complicate or inhibit the bulk recycling of a single plastic type, but additives, including novel or innovative bio-additives could also be used to improve recycling rates without compromising the properties of the materials
  • effective tracking, transport, separation or sorting and recycling technologies for harder to tackle polymers
  • more efficient recycling technologies that maintain material properties over a greater number of lifecycles
  • novel approaches to the analysis of available plastics data, to enable tighter material and product circularity loops including methods for measuring and estimating the embodied or lifecycle carbon emissions of plastic materials and products
  • plastics constructed from bio-based and alternative feedstocks to petrochemicals, that contribute to a circular system

Any proposed new plastics, including novel bioplastics, must demonstrably conform to current and planned or anticipated regulatory controls, as well as aligning to the ambitions of the existing and predicted overall plastics system.

The substitution of plastics by other materials is outside the remit of this opportunity.

Proposals addressing plastic packaging are not excluded from this opportunity, but applicants must demonstrate how any project would be complimentary to other investments such as the smart sustainable plastic packaging challenge.

Whole system approach

You should consider the whole system (technological, economic, social, cultural and environmental) within which the proposed research outputs would sit.

You should consider:

  • how the different parts of a system, at different scales (material, product and sector) influence each other as a whole
  • the relationships and feedback loops between them
  • the wider social, legal, regulatory, economic and environmental context

Responsible innovation and environmental sustainability

All projects funded via this opportunity must:

  • follow the principles and guidance contained within UKRI’s environmental sustainability strategy (PDF, 1.5MB), regarding the sustainability of the research methodologies used
  • consider the responsible innovation and environmental sustainability aspects of the proposed research approaches, and the associated project outputs and outcomes

A shift to a more circular plastics economy provides an opportunity for the UK to achieve more sustainable and clean economic growth and prosperity. This should involve the consideration of the risks, costs and trade-offs associated with different materials, technologies and approaches and an appropriate degree of application of tools such as life cycle analysis.

Project partners

You should include at least 1 appropriate project partner (industrial, government or third sector), to demonstrate that:

  • the project will address a tangible need
  • a credible potential translation pathway for the research output is in place

Both sector specific and multi sector proposals are welcomed.

Project partner engagement must demonstrably extend beyond an advisory role, such as by providing:

  • a cash contribution to the project, such as a direct investment to support a project research activity
  • ‘in-kind support’, for example:
    • access to equipment or other resources
    • employee time allocated to involvement in research activities

It should be clear that each project partner has a clear interest in the project achieving outcomes and impacts relevant to its business or mission.

You will need to have secured a commitment to collaborate on the proposed project from at least one project partner for the outline stage of your application.

Funding and duration

We have up to £7 million to fund a number of projects.

Your project can be up to £1.75 million at 100% full economic cost. We will fund 80% of the full economic cost.

Projects can be up to 36 months in duration.

Equipment over £10,000 in value (including VAT) is not available through this opportunity.  Smaller items of equipment (individually under £10,000) should be in the ‘Directly Incurred – Other Costs’ heading.

How we will assess your application

Assessment process

Full proposals will undergo internal checks by EPSRC staff to ensure that they meet the opportunity requirements.

Peer review and prioritisation panel

The full proposals will then undergo postal peer review, where they will be assessed by relevant independent experts, identified by EPSRC, who will score the proposal against the assessment criteria and provide comments.

When you submit your proposal, you should nominate 3 reviewers from different organisations with the expertise to review your proposal, see ‘Nominating reviewers’ for detail. We usually select 1 of your nominations as a reviewer (although this isn’t always possible if we identify a conflict of interest or if your nominated reviewers are unavailable).

You will receive a copy of the reviewer comments and be given the opportunity to provide a written response. We reserve the right to reject proposals at this stage if reviews are unsupportive.

A peer review panel will then be formed including a mix of independent academic and industry members, with a range of expertise relevant to this opportunity. We will provide the panel in advance with your full proposal, the reviews of it and your written response to the reviews. The panel will discuss the written reviews and your response to them, subsequently assigning the proposal a numerical score against the assessment criteria. They will then produce a rank ordered list of proposals.

EPSRC and BBSRC will use the rank ordered list to determine priority for funding.

We expect to contact applicants with the outcome of their application within 2 weeks of the prioritisation panel meeting.

Additional info


Plastics are an essential material within advanced societies. Worldwide, approximately 370 million tonnes of plastics are produced each year.

In 2025, plastic production is expected to reach over 600 million tonnes per year (Plastic Atlas, facts and figures about the world of synthetic polymers). Primarily developed from fossil fuel feedstocks, they have a broad range of applications from preserving food to lightweighting of components to improve energy efficiency of advanced technologies.

Plastics are cheap to produce, have often unrivalled functional properties and are durable. However, their extraction and production can have damaging impacts, their low cost has led to a culture of disposal and their durability can be problematic at the end of their use-life. A circular economy for plastics could help:

  • reduce resource use and the damage this causes
  • reduce waste
  • improve recycling and recovery processes

Plastics recycling is a flourishing industry globally, but it is focused primarily on solid packaging. Approximately 50 to 55% of unwanted plastic products are incinerated (energy from waste), go to landfill or become fugitive in the environment.

Where options do exist current recycling technologies also vary in efficiency and effectiveness. For instance pure polyethylene terephthalate waste can be recycled repeatedly without markedly impacting on the properties of the material.

However for many polymers current approaches to recycling degrade the material over time. Current methods for recycling of plastics can also be very energy intensive and limited in their ability to process mixed materials.

The UK and devolved administrations have a number of policies of relevance to the area setting out a number of ambitions over the coming decades. These include:

Grant additional conditions

Grants are awarded under the standard UK Research and Innovation (UKRI) grant terms and conditions.

Responsible innovation

EPSRC is fully committed to develop and promote responsible innovation. Research has the ability to not only produce understanding, knowledge and value, but also unintended consequences, questions, ethical dilemmas and, at times, unexpected social transformations.

We recognise that we have a duty of care to promote approaches to responsible innovation that will initiate ongoing reflection about the potential ethical and societal implications of the research that we sponsor and to encourage our research community to do likewise.

Links to wider programme or area

There are many different definitions of a circular economy. At its heart UKRI considers it to be about:

  • producing less
  • keeping the products, materials and resources we do use and produce in circulation at their highest value for as long as possible
  • recovering them after use

The UKRI 2022 to 2027 strategy aims to drive the development, adoption and diffusion of green technologies, building a sustainable circular economy and a greener future for the UK as we move to net zero. More circular use of resources is crucial to:

  • achieving net zero carbon emission targets
  • reducing resource consumption, waste and pollution harmful to biodiversity
  • enhancing health and resource security
  • offering the UK significant economic, social and environmental benefits

Supporting the interdisciplinary, whole systems, engineering, physical sciences, maths and information and communications technology research and innovation needed to deliver a circular economy is a priority for EPSRC. It directly delivers against EPSRC’s engineering net zero priority ambitions to collaborate across UKRI to deliver whole systems approaches and solutions to:

  • reduce resource use
  • eliminate pollution
  • deliver a sustainable zero carbon future

BBSRC supports multistakeholder bioscience funding that generates economic, environmental and social benefits through a circular bioeconomy.

This opportunity follows the UKRI £20 million Plastics Research and Innovation Fund and runs concurrent to the UKRI £60 million smart sustainable plastic packaging Industrial Strategy Challenge Fund initiatives.
