Waste regulation considerations
Does IBA get tested when it is delivered to Saxon Pit?
All IBA waste arrives from Incinerators at any permitted Installation site. The IBA is tested by accredited technicians who sample the waste from the incinerators and pass it, if acceptable to move to a waste operator. In this instance, Johnsons receive IBA from many incinerators across the country. Some Incinerator Bottom Ash will consist of municipal solid waste such as wood, plastics, paper food that can be industrial or medical material. You cannot burn waste that falls outside of the specified waste codes. https://assets.publishing.service.gov.uk/media/5a7c909ced915d48c24109e5/pb13889-incineration-municipal-waste.pdf
There is also a 'Quarantine area' where IBA could potentially be stored if test results have been delayed. This quarantine area has never needed to be used to date.
The quarantine is separate and away from the tested IBA area and would be tested by the installation teams whilst in quarantine.
Are there IBA/IBAA Dust emissions from JARL outside of the permit boundary. Could IBA/IBAA build up inside the Pit
Johnsons Aggregate Recycling Limited (JARL) have a Dust Emission Management Plan (DEMP) that is written by the operator in line with their dust modelling submission prior to permit authorisation and is sanctioned by the EA.
JARL have three sampling areas across site with their monitoring devices, these are regularly visited by our team and we can also request the findings of the sampling being carried out. To date, there has not been any substantiated IBA dust escaping from the permit boundary. We are aware that continuous sampling of dust surrounding the Pit is essential. We are deploying a Mobile Monitoring Facility (MMF) in the summer of 2026. This device will measure dust volume, direction and give us more data to ensure that both operators are working with the permit conditions.
IBA/A could build up in the Pit, currently there is no evidence that it is, but we are monitoring the dust situation on a regular basis. Our dust monitoring outside of the permit boundary has shown dust particles, but nothing containing IBA/A. With the MMF deployment, we hope to capture more detail on dust falling outside the permit boundary.
