FAQs

Who’s proposing to rebuild the Edmonton incinerator?

The North London Waste Authority is in charge. The NLWA arranges waste disposal for Barnet, Camden, Enfield, Hackney, Haringey, Islington and Waltham Forest. It says that part of its primary function is to “promote waste minimisation and recycling.”

Yet recycling rates in North London plateaued over the last decade, and even fell in the year ending 31 March 2019. The NLWA has a longstanding goal of reaching a 50 % recycling and composting rate by 2020, but it’s nowhere near reaching it — it’s stuck below 30%. The incinerator might be a reason for the low recycling rates (see p 9 of this document for more evidence, which applies to the impact of incineration in general and is not specific to the Edmonton plant). 

The NLWA is made up of 14 councillors, two from each of the boroughs. Twelve are from the Labour Party and two are from the Conservative Party.

How far along is the project?

Pre-construction phase. Construction on the incineration facility (‘ERF’) is not set to begin until very late in 2022. The construction contract hasn’t yet been tenured. We still have time to change the plan.

There’s no fixed expiry date on the current incinerator. We can take a moment to develop a different plan.

If this project moves forward, what will happen?

We predict that this project would end up as either (a) an environmental nightmare that London can’t escape from or (b) a financial albatross in which the facility has to be shut down, at great cost, because of future climate, recycling and public health laws.

Have such incinerator projects been stopped before?

Dozens of incinerator projects have been stopped in the UK in the past decade.

How can we oppose the incinerator rebuild without a fully-fledged alternative plan in place?

We advocate a stop and think approach. Six of the seven boroughs have declared a climate emergency. If these declarations are to mean anything, the councils will have to develop a better waste treatment plan.

The first step is to acknowledge that an incinerator is not the right way forward. Incineration goes directly against the EU’s circular economy goals, which call for all plastic to be recyclable or compostable by 2030. It is part of the linear economy — ‘make, use, dispose’. Some experts call it ‘skyfill’.

The next step will be to leverage the collective resources and intelligence of the seven boroughs and develop a better plan. A key element of the plan will be sorting. We need to sort rubbish into its constituent parts — metals, plastics, organic materials — to retain their value and keep them in the circular economy.

We have a general outline of a better plan (see more info in other FAQ) — including a plant that sorts materials first — and we’re working on a more detailed document, but we have only limited resources available to us, especially compared to the NLWA. 

The NLWA has had many years to plan the incinerator rebuild/expansion and has used a great deal of public money to do so. We propose the NLWA start redirecting its funds towards a plan that meets the environmental and public health needs of the 2 million residents that it works for. We need to come up with a better plan that treats our waste as a resource — a part of the circular economy — rather than a problem.

At the moment the NLWA is instead using our money to sell us its plan. Smooth communications are key to the boondoggle: the NLWA signed a £750,000 contract with a PR firm just for work on this new incinerator project.

Environment & Energy

What are the projected carbon emissions?

The NLWA has not released a climate impact assessment study, nor made an estimate of the incinerator’s expected carbon emissions, at least not in public.

However, the NLWA has said that the new incinerator would have the capacity to process 700,000 tonnes of rubbish per year. From this figure we can estimate that the carbon emissions will be roughly 700,000 tonnes per year (yes, it’s about one to one).[1] That’s more than the borough of Hackney emits in a year, according to official data.

[1] How we made this estimate: The current Edmonton incinerator burns more than one tonne of carbon per tonne of waste, according to data from the Environment Agency Pollution Inventory for 2016 (https://data.gov.uk/dataset/cfd94301-a2f2-48a2-9915-e477ca6d8b7e/pollution-inventory). There is no reason to believe this figure would change much when the new facility opens, as carbon emissions are determined mainly by feedstock (that is, what’s in our rubbish bins, not the technology used to burn it).

Isn’t incineration a way of recovering energy and powering London homes?

The incinerator would produce electricity or heat from the rubbish it burns. The NLWA calls the incinerator an ‘energy-from-waste’ or ‘energy recovery’ plant, and even calls the site Edmonton EcoPark.

However, incineration is a very inefficient way to create energy. It captures only a small amount of the calorific value of the materials it burns. This makes it hugely carbon intensive, even more so than burning traditional fossil fuels. Recycling plastic waste is actually a better way to ‘recover’ energy, as the energy saved by not needing to extract fossil fuels and create new plastics is more than that which can be gained from burning it.

Don’t we need incineration? Isn’t landfill the only alternative?

There are many alternatives, just in the narrow sense of ‘what type of plant do we want to build?’ These include material recycling facilities, ‘mechanical biological treatment’, steam autoclaving, underground storage of sorted materials, and anaerobic digestion.

The main idea is to have a system that sorts our rubbish and makes the best use of each type of material. A small portion, at least at first, might still end up landfill or incineration, but at nowhere near the scale NLWA currently has planned. 

And this isn’t merely a question of what type of plant to build. It’s about the type of waste management system that North London boroughs should have. The NLWA wants to spend £100s of millions on a new incinerator when it could invest that money not only on high-tech sorting and recycling facilities, but also in its people — roughly half of the rubbish going to Edmonton could be recycled if people simply threw it in the right bin.[1] If more money were spent on education and awareness raising, much of this ‘rubbish’ could be recycled. In the two-year period ending 31 March 2019, the NLWA spent about £4.3 million developing plans for the new incinerator and less than £2 million on education and waste reduction efforts.[2] And of course we don’t have to rely on education alone. Tax policy — levies or rewards — could encourage people to recycle more.

[1] A 2015 report from Barnet — one of seven boroughs that send their rubbish to Edmonton — showed that about 55 to 57 percent of the waste in black rubbish bags (‘residual waste’, in the lingo) is recyclable — and that’s using a very narrow definition of ‘recyclable.’ (If technology improves and/or global commodities markets shift so that it’s not so cheap to make virgin plastics and so on, many more used materials will become valuable and thus widely recyclable.)

Won’t it capture some of the carbon? Won’t it use state-of-the-art technology?

No, there’s no plan to capture the carbon, and there’s nothing sophisticated about burning all incoming materials en masse. The incinerator will not have any sorting mechanism, such as high-tech scanners that detect the molecular structure of plastics — and sorting materials is the best way to start the process of retaining their value.

In fact, incineration kills innovation. Last year, in testimony before Parliament, the chief scientific advisor to DEFRA said that ‘incineration is not a good direction to go in’ because we should be finding better ways to use the value of materials, rather than turning them into carbon dioxide.

What comes out of an incinerator’s smokestack?

In addition to greenhouse gases, incineration releases nitrogen oxides, sulphur oxides, hydrogen chloride, dioxins, furans, heavy metals, and particulate matter.

The Edmonton incinerator released more than 10 tonnes of particulate matter in 2017. DEFRA says that there is ‘increasing evidence’ that particulate matter leads to respiratory and cardiovascular problems, which can be fatal.

Finances

How much will this new incinerator project cost?

The construction alone is expected to cost about £650 million. This figure doesn’t include operating costs. More importantly, it doesn’t include environmental and public health costs, which, among other problems, lead to financial expenditures.

Who’s paying for this? Will it affect my council tax?

Yes, it will. The project is funded by council taxes. The NLWA is taking loans from a public borrowing fund, and the seven boroughs will pay back those loans with money from council taxes.[1]

The NLWA has not provided an estimate of how much the project will affect council taxes.

[1] Source: David Cullen, Programme Director for the NLWA incinerator rebuild/expansion. He explained this in response to a question during an Edmonton ward meeting on 25/9/2019. The NLWA has not responded to emails asking for clarification on how the project is being funded (among other questions). 

Aren’t the environmental costs already being accounted for?

No. The UK has a landfill tax, but no incineration tax. This policy gap is one reason why incineration has become so common in the UK over the last 10 to 15 years.  

Incineration is also — somehow — exempted from the European Union Emissions Trading Scheme (cap and trade). So while gas-fired power plants pay for the carbon they emit, incinerators do not, even though they emit more carbon per unit of energy created.

How long will the new incinerator run?

The NLWA says it will run for at least 25 years (until 2050). It could run for half a century, like the current plant.

This doesn’t fit with climate goals. There’s an urgent need to reduce emissions to net zero by 2030 — the Labour party recently passed a motion to do so.

If the rebuild goes ahead, the seven boroughs will be paying for the plant — paying back the incinerator loans — for decades, and will have little ability or incentive to fund an alternative waste management program at the same time. This means going green on waste will have to wait another 30 to 50 years.

My Council

Is my Council keeping close track of the carbon emissions coming from the rubbish we send to the Edmonton incinerator?

Apparently not. The incinerator is in the borough of Enfield, so its emissions are counted as Enfield’s in the official government tally, even though only a small portion of the rubbish comes from that borough.[1]

The other six boroughs should of course be keeping track the carbon emissions produced by their rubbish, but it’s unclear if they do.

Hackney Council, at least, does not appear to take account of these emissions. In an email exchange with this campaign in late August, a Council representative said that he was not sure whether Hackney’s contributions to the incinerator feedstock were being accounted for in official emissions figures.[2] (Our campaign has since confirmed with BEIS that they are not counted.)

[2] The representative was Paul Dobbs, Waste and Environment Manager, Hackney Council. ‘Unfortunately I have no idea about your…question and don’t know who at the council would,’ he wrote in an email to Edward Carver on 30/08/2019.

I trust the judgment of my Councillor. If s/he supports the incinerator rebuild, why should I oppose it?

The plan, which has been in the works for many years, is now out of date: the Government’s Resources and Waste Strategy has a 65% recycling target a strong focus on the circular economy. We should avoid institutional inertia and scrap the plan.
