Viridor has been providing the emission reports since March 2019 (it has been burning long before this, but considered testing) They are hidden on their website https://www.beddingtonerf.info/emissions-archive.html updated twice a month (around 10 days after the end of the month and 10 days after the mid-month cut off they pick)
Between 1 March 2019 and 30 September 2024 (67 months) there have been 60 breaches of the TP3836CT permit.

The Environment Agency permit has seen 23x CO (Carbon Monoxide), 20x VOC (Volatile Organic Compounds), 10x SO2 (Sulphur Dioxide), 3x EPR Compliance Assessment Report, 2x HCI (Hydrogen Chloride) & 1x PM (Particulate Matter) exceedances.
So far the incinerator has not reported any breaches in NOx (Oxides of Nitrogen) or NH3 (Ammonia), the other two emissions monitored.
On the 13th March 2022 the Croydon Council (under new administration after a Conservative Mayor had been elected, replacing Labour) has written to Viridor about the high number of emissions exceedances (five) at the plant during just 6 weeks of May and the first fortnight of June 2022. The subsequent SLWP South London Waste Partnership meeting that had already been postponed was not broadcast publicly as every single meeting (not cancelled) since the beginning of data had been published.
On the 16th October 2023 there was a power outage by UK Power Network, backup power failed to operate leaving the normal cleansing of the emissions from the incinerator non-operational resulting in dark plumes of polluted smoke emitting from the chimneys. Viridor failed to report the incident to the Environment Agency resulting in three separate breaches of the permit for the incident. Luckily concerned residents who live under the emissions zone of the regular permit breaching incinerator reported the visual and olfactory conditions to the Environment Agency incident hotline on 0800 80 70 60, so they became aware and visited the incinerator and witnessed the failure for themselves.
An Environment Agency Consultation proposing to increase the waste processing amount (and therefore pollution) by 10% was held between 10 November 2022 and 23 December 2022. The South London Waste Partnership representation along with the councils of Merton and Sutton used incorrect data compiled by the South London Waste Partnership to oppose the application. Only AFTER the consultation ended, and yet ANOTHER breach before the final comment had been submitted to the consultation, the South London Waste Partnership conceded the information they have been quoting was wrong, and that the evidence published by Merton.TV website is accurate.
