Fury as Scotland’s councils burn 30,000 tonnes of recyclable waste
Huge increase in carbon-emittingb incineration ‘driven by Government attempts to reduce landfill’
MORE than 30,000 tonnes of waste – 12 per cent of the country’s overall amount for recycling is being burned annually in incinerators.
Scotland’s climatedamaging incinerator boom ‘being driven by Government attempts to prevent waste from being disposed at landfill’
MORE than 30,000 tonnes of waste put out every year for recycling in Scotland end up being burned in incinerators and causing climate pollution, according to an investigation by The Ferret.
Over 12 per cent of waste collected for recycling by 17 councils is sent to energyfrom-waste combustion plants. In Edinburgh, the figure is 29%, in West Lothian 27%, in Glasgow 16% and in Aberdeen 15%.
Campaigners have criticised councils for “sending valuable resources up in smoke” and “harming recycling”.
Experts cautioned that incineration could no longer be regarded as a “low-carbon” industry. Councils pointed out that a proportion of the waste collected for recycling was contaminated by food, nappies, plastic wrappers and other items that couldn’t be recycled. It was better to convert this into energy than to dump in landfill sites, they argued.
Incinerating waste to produce energy has been booming in Scotland, with the annual amount of waste being burned increasing more than sixfold between 2013 and 2019 to nearly half a million tonnes.
This looks set to keep rising steeply, as there are now 11 new energy-from-waste plants being built or planned.
In the next few months, waste company Viridor is due to apply for planning permission for a huge new plant near Stonehouse in South Lanarkshire.
If it gets the go-ahead, it would burn up to 330,000 tonnes a year and become the largest waste incinerator in Scotland.
The incinerator boom has been driven by Government attempts to prevent waste from being disposed as landfill.
In 2019, the Scottish Government delayed a proposed landfill ban from 2021 to 2025, following concerns that councils would fail to meet the deadline.
But independent news organisation The Ferret reported in September 2020 that plans to treble the amount of waste burned in incinerators could prevent Scotland from meeting its targets to increase recycling. Environmental groups were concerned that a large proportion of waste would be burned rather than recycled.
Combustion plants
NOW figures from councils reveal that many have been sending significant proportions of waste they collect in recycling bins to combustion plants. For 17 of the most populated areas, it’s an average of one in every eight bins, amounting to well over 30,000 tonnes in 2019/20.
The highest was Edinburgh, which sent three-tenths of its recycling waste totalling 6,960 tonnes to be incinerated in 2019/20.
The council helps run an energy-fromwaste plant at Millerhill, near Musselburgh, which can handle up to 155,000 tonnes a year.
West Lothian sent more than one-quarter of its waste collected for recycling – 5,061 tonnes – for incineration. The council said it went to plants in Latvia, Sweden, Denmark, Yorkshire, Lanarkshire and East Lothian. In 2019/20, Glasgow sent 4,664 tonnes of recycling waste — 16% — to Viridor’s waste treatment plant at Polmadie. There it was processed and burned to produce electricity.
Aberdeen sent 4,025 tonnes — 15% — to be burned in plants in Scandinavia, England and Shetland. Several councils declined to say how many tonnes of waste collected for recycling were incinerated.
Dundee City Council claimed that none of the waste it collected for recycling was incinerated. Three other councils said none of their waste was burned: Falkirk, North Lanarkshire and Fife.
Summary data on Scottish local authority incineration rates was released on social media after a UK-wide investigation by Channel 4’s Dispatches programme. The Ferret asked councils to say what was happening in their areas. Environmental group Friends of the Earth Scotland is now warning that incineration is spiralling out of control.
‘Appalled’
FOES campaigner Sarah Moyes said: “People will be appalled to find out that many councils across Scotland are sending the materials they put in their recycling bins to burn in incinerators instead.
“There are serious environmental concerns around the burning of waste, but now councils are wasting valuable recyclable materials by burning them too. Instead, the focus should be on reducing the waste we produce.”
Ms Moyes is now calling on councils to urgently address the contamination of recycling waste with better education, clearer labelling, and more consistent collections. She added: “We need swift and decisive action to introduce a moratorium on the building of new incinerators before we lock ourselves into decades of sending valuable resources up in smoke.”
The UK Without Incineration Network has written to the Scottish Government insisting that incineration can’t be described as recycling energy.
The network’s co-ordinator Shlomo Dowen said: “Much of what is currently incinerated could and should have been recycled or composted.”
“It is important to ensure that the widest range of materials are accepted for recycling or composting, and that material is only disposed of if there is genuinely no way to recycle it. If Scotland is to fulfil its ambitions for a more circular economy then Scotland needs to stop building any new incineration capacity. If something cannot be recycled or composted it should no longer be sold.”
Incinerators, unlike other climate polluters, have been omitted from a new post-Brexit trading scheme designed to cut carbon emissions.
The omission, which was agreed by the Scottish and other UK governments, is currently being challenged by campaigners in the High Court in London.
There is growing concern among experts about the carbon pollution from incinerators.
‘Highly sensitive’
Chief executive of the governmentfunded agency Zero Waste Scotland, Iain Gulland, said: “While energy from waste may have been ‘low carbon’ in previous decades when Scotland, and the UK, had a much more carbon-intensive energy system, rapid and continuing decarbonisation has changed the equation.
“Energy recovery remains slightly preferable to landfill under current conditions, but this is highly sensitive to relatively small changes in waste composition, and ongoing grid decarbonisation will further weaken the case. For now, incineration remains the least bad option for treating municipal solid waste currently practised in Scotland. The challenge, as always, is to continually look to reduce waste as much as possible, recycle as much of what remains as possible, and treat the residual waste which is left in the manner with the lowest impacts.”
Professor Sir Ian Boyd, a former UK Government scientific adviser from the University of St Andrews, thought it was inevitable that people would put the wrong material in recycling bins.
“Whether it is better to incinerate low-grade waste materials or to dispose of them in other ways, such as putting them in landfill, will depend of the material and the quality of incinerators available,” he said. “Wet organic waste could be used to generate methane for power generation. Other waste can be burned to directly generate heat. But because both these contribute to emissions they should be minimised and highly stable materials such as plastics may be better stored in landfill.”
The waste industry defended the role of incinerators in dealing with some waste. “It is simply wrong to imply that material collected for recycling is instead sent straight to energy-from-waste plants,” said Stephen Freeland, policy adviser to the industry body the Scottish Environmental Services Association.
“Contamination of material presented by householders in their recycling bin is a chronic problem and for some councils this can be in excess of the 12.5% pointed to in the research. This is material that, despite all best efforts, simply cannot be recycled and for which an alternative treatment option must be found.”
He added: “The non-recyclable residues from sorting plants are often sent to energy-from-waste facilities, which provide the most practical and cost-effective solution, and ensure that this material can still be put to good use by powering Scotland’s homes and businesses instead of being lost to landfill.”
