Waste Incinerators

Debate between Mary Creagh and Ben Obese-Jecty

Thursday 3rd April 2025 Westminster Hall

[Mary Creagh]

The right hon. Gentleman asked about a couple of things in his speech, so I will respond to those first. He asked about composition analysis—we are getting into deep technical detail—and it is about what is actually being incinerated. What is being burned? The right hon. Member for Islington North asked why we do not just put plastic in the ground, as it would just sit there, inert. What is going into incineration?

My understanding is that the emissions trading scheme was consulted on under the previous Government—that bringing local authority energy-from-waste facilities into the ETS from 2028 was consulted on in 2024, so it was an in-flight proposal—but I am very happy to be corrected if I am wrong. The residual municipal waste composition study, covering the period from May 2024 to May 2025, will be published later this year, and I know we cannot wait. It will be interesting, because it is essentially the baseline. It is where we will see if the changes are going to start feeding through.

We said in our manifesto that we would reduce waste by transitioning to a circular economy, which is one of the Secretary of State’s five priorities for DEFRA. I am really proud to be the Minister responsible for that.

The right hon. Member for Islington North asked why we cannot just landfill waste plastics, but there are wider environmental impacts from landfilling plastics than simply carbon emissions, including the issue of microplastics. We do not yet fully understand how plastics degrade in landfill in the long term. Emerging research is exploring the potential of plastic-degrading bacteria in landfills, which could break down plastics and in turn impact greenhouse gas emissions. However, I gently say that we cannot solve today’s problems by storing them up for future generations.

The UK emissions trading scheme is minded to expand the scope of the emissions trading scheme to include energy-from-waste facilities. A consultation on this was published in 2024, which included a call for evidence on incentivising heat networks. With the energy-from-waste plants, there is electricity generation, but there is also a massive excess of heat. Most of that heat just dissipates, but it would be much more efficient to use it, as Coventry city council has with its mile-long pipe under London Road, which heats the local swimming pool or Coventry University’s buildings. I understand that the authority will respond in due course.

At the end of last year, we set out that we will require proposals for new facilities to demonstrate that they will facilitate the diversion of residual waste away from landfill or enable the replacement of older and less efficient facilities. This position reflects the evidence and analysis we have published. It also reflects the waste hierarchy and is congruent with the transition to a circular economy.

Even after the successful delivery of our recycling reforms, there will be sufficient residual waste capacity to treat forecast municipal residual waste arising at national level. On that point, my hon. Friend the Member for Derby South is correct. However, there are five areas in England where more than half the residual waste collected by local authorities was sent to landfill in 2023-24. Landfill was also still relied on for an estimated 5.4 million tonnes of non-municipal, non-major mineral waste in 2022, which is the most recent year for which data is available.

We know about the waste that goes into our bins, but there is a lot of other stuff coming out of construction sites, and so on. My hon. Friend the Member for Rushcliffe (James Naish) and I had a chat about this issue in the Lobby, but the analysis the Government published at the end of last year sets out the regional disparities and the regional capacities. It is a good read.

[Ben Obese-Jecty]

I am listening to the Minister’s comments about capacity. I appreciate that she may not have the specific details in front of her, but I would be interested to know whether Cambridgeshire sits within one of the undercapacity regions, and whether that is why so many incinerators are being built in those constituencies.

My other point—I appreciate this is slightly tangential—is that residents of the village of Pidley in my constituency will find themselves equidistant from two incinerators if both are approved. Is there a minimum distance that a village can expect to be from an incinerator? If so, what is it?

[Mary Creagh]

In law, as I understand it, it is for local planning authorities to decide on planning applications. The hon. Gentleman will be surprised to hear that I have not memorised the full 60 pages—I do my best, but I am just not that good. I am very happy to write to him about the Cambridgeshire point, but he can see it online.

The consultation proposed aligning the ETS with the extended producer responsibility for packaging to allow local councils to pass the emission trading costs from the incineration of plastic packaging waste to the producers of plastic packaging. It also sought views on how best to support local authorities in managing ETS costs.

It is not for the Environment Agency to decide where an energy-from-waste plant is built, or whether it is the right solution for treating waste. It can revoke environmental permits only where there is clear evidence of ongoing non-compliance.

I have discussed simpler recycling, and we heard some excellent examples from the hon. Member for Sutton and Cheam (Luke Taylor) about food waste, including Too Good To Go. The Government have set up a £15 million food waste grant to tackle on-farm food surplus.

We have also set up the circular economy taskforce, bringing together experts from the Government, industry, academia and civil society. It will work with businesses on what they want to see to create the best possible conditions for investment. We are developing a new circular economy strategy for England, which will mean an economy-wide transformation in our relationship with our precious materials. It will kick-start the Government’s missions to have economic growth, to make us a clean energy superpower and to accelerate the transition to net zero. Through our efforts to tackle waste crime, of which there is a great deal in the waste sector, we will take back our streets.

On our capacity announcement, we know there is a need to minimise waste incineration, but it is still a better option than throwing rubbish into landfill. Energy-from-waste facilities provide around 3% of the UK’s total energy generation. They can support the decarbonisation of heating our homes and businesses, helping to cut customers’ bills. Energy from waste can both maximise the value of resources that have reached the true end of life and avoid the greater environmental impact of landfill, which creates its own problems.

I will conclude to give my hon. Friend the Member for Derby South time to respond. I encourage investors, financiers and businesses to invest in infrastructure that supports the movement of resources up the waste hierarchy. Our recycling infrastructure capacity analysis, published in partnership with the Waste and Resources Action Programme, alongside our packaging reforms identified forecast capacity investment opportunities of 1.7 million tonnes a year for paper packaging reprocessing and 324,000 tonnes a year for plastic packaging reprocessing by 2035.

We want to unlock investment, and last week my officials met the Lord Mayor of London, Dutch officials and members of the UK and Dutch financial sectors to agree to form a circular economy finance coalition to boost investment in the transition to the circular economy to which we are committed. That is no small task, but by working together we will keep our resources in use for longer.
