Allerton Waste Recovery Park: A Working Example of Integrated Waste Treatment in North Yorkshire
Allerton Waste Recovery Park is one of the UK’s best-known examples of an integrated waste management facility. Located at Allerton Park Quarry, near Knaresborough, it treats residual waste from North Yorkshire and the City of York and combines mechanical treatment, anaerobic digestion and energy from waste on one site.
The facility opened in 2018 and can process up to 320,000 tonnes of waste per year. It was originally developed in partnership with Amey, and North Yorkshire Council now describes it as being operated in partnership with Thalia Waste Management.
For anyone interested in how local authorities can move away from landfill, Allerton remains an important case study. It is not simply an incinerator. It is a waste recovery park designed to recover recyclable materials, treat the organic fraction through anaerobic digestion, and use the remaining residual waste to generate electricity.
Key Takeaways
- Allerton Waste Recovery Park opened in 2018 and remains a major waste treatment facility for York and North Yorkshire.
- The site can process up to 320,000 tonnes of waste per year, including household waste and some commercial and industrial waste.
- Three main technologies are used: mechanical treatment, anaerobic digestion and energy from waste.
- The anaerobic digestion plant treats the organic fraction separated from incoming residual waste and produces biogas for renewable electricity generation.
- The energy from waste plant treats the remaining residual waste and generates electricity from steam produced during combustion.
- The facility helps divert waste from landfill, with North Yorkshire Council stating that it reduces the amount of household rubbish sent to landfill by at least 90%.
- The policy context has changed since the original article was written, especially with England’s Simpler Recycling requirements from 31 March 2026, which require more consistent household recycling and food waste collections.
What Is a Waste Recovery Park?
The term waste recovery park is used to describe a site where more than one waste treatment or recovery process is brought together in a coordinated way.
In the case of Allerton, the word “park” is important. It does not describe a public open space. It refers to the co-location of different waste recovery technologies on one operational site.
A conventional materials recovery facility, often shortened to MRF and pronounced “murf”, is normally focused on separating recyclable materials so that they can be sent to end markets. A waste recovery park may go further by combining recycling, biological treatment, energy recovery and ash recovery in one system.
Allerton Waste Recovery Park is therefore more than a simple MRF. It includes:
- a mechanical treatment plant;
- an anaerobic digestion plant;
- an energy from waste plant;
- incinerator bottom ash recovery; and
- supporting infrastructure for emissions control, power generation and site operations.
Allerton Waste Recovery Park: Fully Operational Since 2018
Allerton Waste Recovery Park became fully operational in spring 2018 after construction, commissioning and independent testing. The facility now forms a core part of the long-term residual waste management strategy for York and North Yorkshire.
The site is designed to reduce reliance on landfill by recovering value from waste that remains after household recycling collections have taken place. Incoming residual waste is first treated mechanically. The process removes remaining recyclable materials, such as metals and some plastics, before the organic fraction is separated for treatment in the anaerobic digestion plant.
Energy from Waste Plant
The remaining material is sent to the energy from waste plant. There, it is thermally treated to produce steam, which is used to generate electricity. North Yorkshire Council says the plant produces enough electricity to supply about 66,000 homes.
The facility also includes a prominent 70-metre-high steel stack, which discharges treated flue gases from the energy from waste process. Modern energy from waste facilities use comprehensive flue gas cleaning and monitoring systems, and emissions are regulated through an environmental permit issued by the Environment Agency.
How the Treatment Process Works
The waste treatment system at Allerton can be understood as a sequence of recovery stages.
1. Mechanical Treatment
The first stage is mechanical treatment. This receives general residual rubbish, mainly from household bins, and separates out materials that can still be recovered. The process removes remaining metals and plastics where it is practical and cost-effective to do so.
This is an important point. Even when householders recycle carefully, some recyclable material still ends up in the residual waste stream. Mechanical treatment provides a second chance to recover some of that material before the remainder is sent for biological or thermal treatment.
2. Anaerobic Digestion
The organic fraction separated from the residual waste stream is treated in an anaerobic digestion plant. Anaerobic digestion breaks down biodegradable material in the absence of oxygen and produces biogas.
At Allerton, the biogas is used to generate renewable electricity. The original design referred to a biogas plant of around 1.1 MWe, and earlier project descriptions referred to annual renewable electricity generation from the AD plant in the range of several gigawatt-hours per year.
In the wider waste management industry, anaerobic digestion is increasingly important because England’s waste policy now strongly favours the separate collection and biological treatment of food waste. Under Simpler Recycling rules, household waste collectors in England are expected, by default, to collect food and garden waste separately from 31 March 2026, subject to transitional arrangements.
3. Energy from Waste
After mechanical treatment and anaerobic digestion, the remaining waste is sent to the energy from waste plant. The EfW plant uses combustion to produce steam, which drives an electricity-generating turbine.
The energy from waste facility has commonly been described as a 24 MWe plant. The wider project has also been associated with annual electricity generation figures of around 203 to 218 GWh, depending on the source and reporting period.
Energy from waste remains a debated technology. Supporters point to landfill diversion, energy generation and the recovery of metals from ash. Critics are concerned about carbon emissions, the risk of locking councils into long-term residual waste contracts, and the need to keep recycling and waste prevention as higher priorities.
Allerton is best understood in that practical context. It is a residual waste facility, not a substitute for recycling, reuse or waste prevention.
4. Incinerator Bottom Ash Recovery
The energy from waste process produces incinerator bottom ash, often called IBA. This material is largely made up of ceramics, glass, slag and similar mineral residues.
At Allerton, the bottom ash is processed so that metals can be removed and the remaining material can be used in construction-related applications, including highway and infrastructure projects.
Air pollution control residues, sometimes called fly ash, are different. These residues come from the flue gas cleaning system and are classed as hazardous waste. They require specialist handling and disposal at appropriately permitted facilities.
Why the Allerton Model is Significant
When it was developed, Allerton Waste Recovery Park was promoted as a leading example of integrated municipal waste treatment. Its significance lay in the fact that several technologies were combined on one site rather than being developed as completely separate facilities.
The project was designed to:
- treat residual household waste from North Yorkshire and the City of York;
- recover additional recyclable material from residual waste;
- treat the organic fraction using anaerobic digestion;
- recover energy from waste that could not otherwise be recycled; and
- reduce long-term dependence on landfill.
North Yorkshire Council now states that the facility is reducing the amount of household rubbish going to landfill by at least 90%. That is a major landfill diversion claim and explains why the project continues to attract interest from waste professionals, local authorities and environmental commentators.
Funding and Project Background
The project was developed as a public-private partnership involving North Yorkshire County Council, City of York Council and private sector partners. The original sponsors included AmeyCespa, Aberdeen UK Infrastructure Partners and Equitix.
The UK Green Investment Bank announced a £33 million investment in the project in 2014. The European Investment Bank also agreed to provide £150 million of backing. At the time, the project was notable as the first joint investment between the UK Green Investment Bank and the European Investment Bank.
Other lenders associated with the project included Nord/LB, Sumitomo Mitsui Banking Corporation, Siemens Bank and KfW-IPEX.
One point that now needs updating from older descriptions is the reference to the UK Green Investment Bank. The bank was sold by the UK government in 2017 and became part of what is now known as Green Investment Group. So, while the Green Investment Bank was an important original funder, it should no longer be described as a current government-owned green investment bank.
Construction and Delivery
Construction began in 2015 at the Allerton landfill and quarry site. Vinci Environment UK was involved in construction, while Taylor Woodrow provided civil engineering works.
The facility moved into its operational phase in 2018 following a lengthy build, commissioning and testing programme. A visitor and education centre is also associated with the site, allowing educational and community groups to learn more about waste treatment and landfill diversion.
Allerton and the Changing UK Waste Policy Landscape
The original article referred to the UK government’s “zero waste” ambitions from the David Cameron era. That wording now feels dated and should be treated as historical context rather than current policy language.
The more relevant modern policy context is the move toward a circular economy, landfill reduction, higher recycling rates and more consistent household collections. In England, the Simpler Recycling framework requires, by default, the separate collection of key waste streams from households from 31 March 2026. These include:
- food and garden waste;
- paper and card;
- glass, metal and plastic, including cartons;
- residual waste for energy recovery or landfill.
Food waste collection is particularly important for anaerobic digestion. Government guidance states that the preferred method for treating separately collected food waste is anaerobic digestion, provided the digestate is of sufficient quality for use on land as fertiliser.
This creates an interesting tension for older integrated residual waste facilities. Plants such as Allerton were designed to recover value from mixed residual waste. Newer policy is pushing more recyclable and organic material out of the residual stream before it reaches such facilities. Over time, that may change the composition of waste delivered to residual waste treatment plants.
Is Allerton a Model for the Future?
Allerton Waste Recovery Park remains a useful model of how a local authority area can reduce reliance on landfill. It shows how mechanical treatment, anaerobic digestion and energy from waste can be combined in a single integrated facility.
However, the “model for the future” argument needs to be handled carefully. Since the project was conceived, the policy conversation has moved on. Waste prevention, reuse, higher-quality recycling, separate food waste collection and carbon reduction have become even more important.
That does not make Allerton irrelevant. It means the site should be viewed as part of the transition away from landfill, not as the final destination for waste policy.
The strongest future waste strategy is likely to combine:
- waste prevention;
- reuse and repair;
- better source-separated recycling;
- separate food waste collection and anaerobic digestion;
- residual waste treatment for genuinely non-recyclable material;
- carbon-conscious planning of future energy from waste capacity.
Final Thoughts
Allerton Waste Recovery Park is still an important UK waste infrastructure project. It demonstrates how local authorities can move large volumes of residual waste away from landfill and recover useful energy and materials from what remains.
At the same time, the waste sector has changed significantly since the project was first proposed. The strongest message for today is not simply that more facilities like Allerton should be built. It is that waste infrastructure must keep evolving as recycling systems, food waste collections, carbon policy and public expectations change.
In that sense, Allerton is both a working facility and a useful case study. It shows what integrated residual waste treatment can achieve, while also reminding us that the best waste is still the waste that is prevented, reused or recycled before it ever enters the black bag stream.

On the heels of a discussion concerning recycling some unopened meals are thrown in the bin, What would certainly occur if we simply tossed these platefuls out the window? Youw ould not do that would you? Responsibly recycling things is a great way to maximize resources. When people think of green energy they think of alternative energy. However, it is just as important to get the most from the non-renewable resources that we use as it is to minimize our use. Recycling electronics prevents unnecessary polluting of landfills as well as reuses resources that non-renewable.
On the heels of a conversation about reusing some broken dishes to make a birdbath, I said, “Hey lets see if we can find a website to show you what would happen if we just threw these plates out instead.” This was perfect! My 5 year old says, “We really love your page/ video. Thank you!”?
I did not like slow videos your video is best and very innovative.
Thanks for making the principle of waste recycling as well as reusing so easily accessible to little us uneducated ones.
Bravo?
Awesome writing and entertaining to read.
My passion for the environment is similar to yours. At Allerton let’s hope they can keep some of the plastic out of our oceans by what they are doing?.
