The United Kingdom Without Incineration Network (UKWIN) has published a report that looks into the climate change impacts of waste incineration in the UK.

The 56-page report found that in 2017 the UK’s 42 incinerators released a combined total of nearly 11 million tonnes of CO2. Around 5 million tonnes of this CO2 was emitted through the incineration of fossil-based materials such as plastic. The 5 million tonnes of fossil CO2 released by UK incinerators in 2017 is estimated to have resulted in an unpaid cost to society of around £325 million.

The report highlights yet another way that plastic is harming our environment, with polluters getting away without paying their fair share for the climate damage that they are causing. The study says that over the next 30 years the total cost to society of fossil CO2 released by UK’s current incinerators equates to more than £25 billion pounds of harm arising from the release of around 205 million tonnes of fossil CO2.

Each tonne of plastic incinerated results in the release of around 1.43 tonnes of CO2. According to the report, a typical waste incinerator built in 2020 would release 2.8 million tonnes of fossil CO2 over its 30-year lifetime. Even when electricity generation is taken into account, this is equivalent to releasing around 1.6 million tonnes of CO2 more than sending the same waste to landfill.

Josh Dowen, Associate Coordinator of the United Kingdom Without Incineration Network (UKWIN), says: “The study shows waste is a rubbish feedstock for generating energy. Burning large quantities of plastics gives rise to a small amount of electricity that comes with a high climate cost. To add insult to injury, those profiting from waste incineration are not paying for the huge cost to society of emitting all these greenhouse gases, and so a UK-wide waste incineration tax is long overdue”.

Dowen continued: The climate change impacts of incineration are worse than landfill. Most of what is incinerated could and should be recycled or composted. It is time to stop thinking of waste as potential incinerator feedstock and time to recognise the urgent need to reduce, re-use and recycle“.

The United Kingdom Without Incineration Network (UKWIN) is a network comprising more than 100 member groups who oppose waste incineration.

UKWIN opposes the incineration of waste, including via gasification and pyrolysis, because incineration depresses recycling, destroys valuable resources, releases greenhouse gasses, and is a waste of money. Incineration has no place in the zero waste closed-loop circular economy towards which we should be working.

The IPCC recently released a report highlighting the urgent need to reduce climate change emissions. HM Treasury is currently considering a waste incineration tax as part of the forthcoming budget, which will be announced on Monday 29th October 2018.

This study is more evidence against the WH Malcolm proposal to build a gasification plant in South Street, Whiteinch.
