The UK's bioeconomy could generate £204 billion in annual revenue from sustainable bio-based materials, but regulatory barriers and policy fragmentation are preventing the sector from reaching its potential, according to a new report from BB-REG-NET, the UK's regulatory science network for bio-based and biodegradable materials.

The report, Growing the UK's Modern Industrial Bioeconomy, identifies fundamental misalignments across government policies that create barriers to market entry for bio-based alternatives to fossil-based materials. With 56 of the UK's 606 government departments involved in bioeconomy regulation, often with conflicting priorities, the sector struggles to find coherent policy support despite £450 million in government R\&D funding and £517 million in private investment over the past five years.

The network presented its findings at UK Parliament yesterday (3 December), calling for a National Bioeconomy Plan with dedicated ministerial oversight, reform of Extended Producer Responsibility (EPR) and Plastic Packaging Tax (PPT) frameworks, and establishment of a UK Bio-Preferred Procurement Scheme modelled on successful international programmes.

Dr Jen Vanderhoven, COO of the Bio-based and Biodegradable Industries Association (BBIA) and project lead for BB-REG-NET, commented: "The UK has all the ingredients for bioeconomy success - world-class research, innovative companies, and ambitious climate targets. What we lack is policy coherence. This report provides a roadmap for government to unlock £204 billion in economic value whilst advancing net zero goals."

The report notes that the current UK bioeconomy comprises 1,200 businesses employing 20,300 people and generating £12.5 billion annually, representing significant untapped potential for growth. Between 2018 and 2024, UKRI invested £450 million in bioeconomy research, yet fewer than 10 per cent of funded projects reached commercial production in the UK, with companies frequently relocating to more favourable regulatory environments.

EPR and tax policies disadvantage sustainable materials

Current UK policies create what researchers describe as a "policy trap" where bio-based materials face higher costs than fossil-based alternatives despite environmental benefits. Under EPR regulations implementing from 2026, compostable packaging receives a RED classification through the Recycling Assessment Methodology (RAM), resulting in fees approximately £520 per tonne higher than conventional packaging.

The Plastic Packaging Tax applies its £225 per tonne charge to bio-based materials whilst exempting fossil-based plastics containing 30 per cent or more recycled content. This creates a situation where sustainable alternatives face additional charges totalling up to £1,600 per tonne, according to previous BB-REG-NET research published in September.

The report identifies the hardest-to-recycle plastic packaging - films, single-use tableware, and flexible materials - as representing 50 per cent of total plastic packaging waste by volume. These materials have the highest cost premiums for bio-based alternatives yet face the most punitive regulatory treatment.

Rachel Rothman, Professor of Sustainable Chemical Engineering at the University of Sheffield and a report author, said: "We're creating regulatory barriers precisely where we need innovation most. Bio-based materials designed for composting are penalised because assessment frameworks were built for fossil-based materials destined for incineration or landfill."

Assessment standards favour fossil-based materials

The report calls for mandatory use of EN 18027:2025 "Bio-based products - Life Cycle Assessment" in policy decision-making, a standard designed to eliminate bias when comparing fossil and bio-based materials. Published in April 2025, the standard addresses structural flaws in existing ISO frameworks that systematically disadvantage materials designed for composting, biodegradation, and carbon sequestration.

Current Life Cycle Assessment (LCA) standards treat biogenic carbon emissions identically to fossil fuel combustion, failing to recognise the closed carbon loop created by plant-based materials. BB-REG-NET research found that when assessing bio-based and fossil-based bottles using existing ISO standards, environmental scores could vary by 103 per cent purely due to methodological choices.

The report recommends bringing forward the planned RAM review from 2029 to 2026, aligning UK ETS, EPR, and PPT frameworks, and establishing an interdepartmental bioeconomy taskforce to coordinate policy across DEFRA, DESNZ, and DSIT.

NHS procurement offers £5.5bn opportunity

The report also identifies public procurement, particularly within the NHS, as a significant market development opportunity. The health service spends £8 billion annually on medical equipment and consumables, with £6.7 billion across 670 contracts identified for single-use plastics.

Analysis suggests 60 per cent of these contracts - worth £5.5 billion - have high substitution potential for bio-based alternatives. During the COVID-19 pandemic, the NHS spent £4 billion on single-use protective clothing, equipment potentially suitable for bio-based materials that could biodegrade or compost after use.

The report proposes a Bio-Preferred Procurement Scheme requiring government departments to purchase certified bio-based products where feasible, modelling on the US BioPreferred Program which mandates federal procurement of over 7,000 certified bio-based products. The US programme has driven market demand and stimulated private sector investment in bio-based manufacturing.

Lord Vallance, Minister of State for Science, Research and Innovation, recently recognised the sector's potential, stating at the BBIA's Demeter Awards that the bioeconomy offers "a unique opportunity to have the design, development and manufacture of new products and materials secured through a thriving bioeconomy."

International competition intensifies

The report contrasts UK fragmentation with coordinated international approaches. The EU published its Strategic Framework for a Competitive and Sustainable EU Bioeconomy, whilst Japan targets a 100 trillion yen (£500 billion) bioeconomy market by 2030.

France's RE2020 policy mandates increased bio-based material use in construction, creating stable demand that drives investment and industrial scale-up. The policy fragmentation across UK government departments creates contradictory regulations that stifle innovation whilst international competitors advance with structured support frameworks.

The report notes that responsibility for bioeconomy policy is fragmented across DEFRA, DESNZ, and DSIT with no single department ownership since the 2018 "Growing the Bioeconomy" strategy was withdrawn. Each department approaches the bioeconomy differently - DEFRA emphasises environmental boundaries, DSIT focuses on scientific innovation, and DESNZ prioritises biomass for energy - creating regulatory conflicts that hinder sector development.

Dr Adrian Higson, Managing Director of NNFCC and report contributor, explained: "The bioeconomy's complexity is its strength. Grasping the opportunity requires collaboration and common thinking across government, without which strategies and regulations will remain fragmented."

The report recommends establishing a designated Minister for the Bioeconomy to coordinate policy across departments, developing a National Bioeconomy Plan aligned with Labour's five missions, and creating investment structures to support biomanufacturing facilities at scale.

Rt Hon Alistair Carmichael MP, Chair of the Environment, Food and Rural Affairs Committee, wrote in the report's foreword that transitioning to a circular economy represents "a great industrial and economic opportunity for the UK" and called for government action to realise the bioeconomy's potential.
