Threatening Capacity Gap and a Billion-Pound Opportunity in British Plastics Recycling: Analysis of the “Reimagining Recycling” Report

The plastics recycling sector in the United Kingdom has reached a critical milestone. Although tightening environmental regulations mean that more and more plastic waste is being collected, domestic processing capacities are declining at an alarming rate. Commissioned by Viridor and prepared by Ceres Waste, Renewables & Environment, the independent report titled “Reimagining Recycling” highlights the current crisis with objective data. The document points out that if the UK eliminates the capacity gap through appropriate investments, it could generate up to £28 billion in Gross Value Added (GVA) and thousands of green jobs; otherwise, a deepening export reliance and significant climate-damaging impacts can be expected.

The Challenge: Rising Waste Volumes, Declining Capacities

Approximately 5.5 million tonnes of plastics are placed on the market or arise as waste in the UK annually, which is equivalent to the weight of every person living in the country. Meanwhile, the industry has suffered unprecedented infrastructural losses: between 2023 and 2025, the UK’s plastic recycling capacity fell by 22 percent. In concrete terms, the permitted and operational recycling capacity dropped from around 1.13 million tonnes per annum to roughly 0.89 million tonnes per annum due to a series of facility closures.

High-profile examples include the closure of Viridor’s Avonmouth facility, the UK’s largest multi-polymer recycling plant with a capacity of 80,000 tonnes per annum, which shut down in November 2024, only two years after commencing operations. Similarly, Berry bpi closed facilities in Renfrewshire and Bridgend, resulting in a combined loss of 142 jobs. Biffa’s 39,000 tonnes per annum Sunderland facility closed in early 2025 following a £7 million investment, and Viridor’s Rochester plant ceased operations in August 2025 after operating since 2014. These closures were driven by challenging market conditions, reduced demand for recycled polymers, high operational costs, and delays in policy implementation.

Threatening Capacity Gap on the Horizon

The UK government and devolved administrations have developed flagship environmental policies, such as Extended Producer Responsibility (EPR) for packaging, Simpler Recycling, the Deposit Return Scheme (DRS), and the upcoming inclusion of Energy from Waste (EfW) facilities in the Emissions Trading Scheme (ETS) from 2026 (with payments due from 2028). Together, these measures aim to drive plastics out of residual waste and drastically increase recycling rates. Currently, only 28 percent of plastics in household and commercial waste streams are recycled; environmental policies project this to rise to 58–69 percent, aiming for a 60 percent overall recycling rate by 2035.

However, if the UK intends to process all of this increased collected material domestically—projected to reach between 4.2 and 4.9 million tonnes separated for recycling by 2060—the capacity gap will widen significantly. Modelling results show that even under a Business-As-Usual scenario, waste growth alone would push the capacity gap to 1.5 million tonnes per annum by 2060.

Under full policy implementation and diversion from EfW, the domestic capacity gap is estimated to rise to 3.6 million tonnes per annum under Scenario 1 and nearly 4.3 or 4.4 million tonnes per annum by 2060 under Scenario 2. In the absence of urgent action, the UK will remain heavily reliant on overseas operators, increasing transport costs and losing local resources. In 2024 alone, the UK exported 600,000 tonnes of plastic waste to countries like Türkiye, the Netherlands, Vietnam, and Poland. Continued reliance on exports could see this figure soar to 4.9 million tonnes annually by 2060.

Infrastructural Needs: What Needs to be Built?

To eliminate the domestic capacity gap and treat all separated plastics within the UK, a substantial pipeline of new reprocessing infrastructure must be delivered quickly. The report quantifies the immediate and long-term facility requirements under Scenario 2 (Recycling Plus):

• By 2030: The UK will require an additional 18 Material Recycling Facilities (MRFs) for sorting, 38 mechanical recycling plants for rigid plastics, and between 13–25 chemical recycling plants to process hard-to-recycle plastic films and contaminated fractions. This immediate build-out requires £3.3 billion of private sector investment.

• By 2040: The cumulative requirement escalates to 38 MRFs, 65 mechanical recycling plants, and 17–29 chemical recycling plants, demanding an additional £1.3 billion of private investment between 2030 and 2040.

• By 2060: A total of 169 new plants (including 51 MRFs, 82 mechanical plants, and 36 chemical plants) will be required to fill the gap completely.

Huge Economic Benefits and Job Creation

Creating “investment-ready” conditions for the plastics recycling sector could unlock between £4.6 billion and £5.9 billion of private sector investment. This infrastructure network would serve as a major driver for economic growth, generating an estimated £25 billion to £28 billion of Gross Value Added (GVA) for the UK economy over the 2023–2060 period. This economic contribution is heavily driven by the permanent employment it creates. According to Office for National Statistics (ONS) metrics, one full-time employee in the waste management and remediation sector generates £137,566 of GVA per annum.

The proposed infrastructure expansion would create between 6,900 full-time positions (under Scenario 1) and 7,700 full-time positions (under Scenario 2) by 2060. Each sorting plant creates approximately 35 jobs, while mechanical and chemical recycling plants create 50 jobs each, many of which are highly skilled STEM positions.

The Climate Imperative: Treating 1 tonne of plastic packaging at an Energy from Waste facility without carbon capture releases an average of 1.7 to 1.8 tonnes of fossil CO2e into the atmosphere. Only closed-loop recycling results in a net carbon benefit. Diverting plastics away from incinerators could avoid between 85 million and 125 million tonnes of fossil carbon emissions (and up to an additional 143 million tonnes of CO2e overall) by 2060.

Saving Taxpayers Money on Net-Zero Infrastructure

Removing fossil-based plastics from residual waste feedstock has an extraordinary financial benefit for the decarbonisation of the energy recovery sector. Plastics are the primary source of fossil carbon emissions in EfW facilities. By diverting plastics to recycling, the proportion of biogenic waste in the remaining feedstock increases. Consequently, a greater proportion of the greenhouse gases captured by carbon capture and storage (CCS) systems will be biogenic in origin, allowing operators to monetize Negative Emission Credits or Greenhouse Gas Removals (GGRs), valued at an estimated £200 to £300 per tonne.

The report notes that without action, the cumulative cost of implementing CCS across all UK EfW facilities would reach approximately £95 billion by 2060. Increasing plastic recycling rates and reducing residual waste volume would reduce the required deployment of CCS, avoiding expensive retrofits on less cost-effective plants. Combined with GGR revenues, a strong domestic recycling sector could reduce the total net cost of achieving net-zero EfW by 42 to 52 percent, saving taxpayers and local authorities between £40 billion and £49 billion.

Reimagining Recycling: Strategic Recommendations for a Stable Offtake Market

While upcoming policies strengthen confidence around securing feedstock, the high volatility of the global offtake market for recycled polymers continues to undermine the business case for private capital. Legitimate recyclers face high operational costs and are frequently undercut by cheap virgin polymers or fraudulent imports misrepresented as recycled material. To unlock the required billions in investment, the report urges the UK government to implement the following interventions:

• Support circular demand: Drive predictable demand and discourage downcycling by setting mandatory recycled content targets for non-packaging plastics, encouraging applications where polymers are reused for the same purposes.

• Enforce traceability and eliminate fraud: Set strict standards for defining recycled polymers and implement mandatory certification schemes to lock out misrepresented material from overseas.

• Review financial penalties: Set Plastic Packaging Tax penalties at a level high enough to genuinely incentivize the adoption of recycled polymers over virgin materials (the tax rate stands at £228.82 per tonne from April 2026).

• De-risk advanced technologies: Provide commercialization support for chemical recycling in line with other emerging energy technologies, including establishing a national approach to “end of waste” status for pyrolysis oil.
