Continuous Emission Monitoring Systems (CEMS) describes the instrumentation that monitors and records emissions from our stacks. The monitoring and reporting process involves many stages of data transfer from the stack analysers, to the process control systems, to the reporting software, before being passed to this public website as a live feed. Each stage is a necessary step in presenting the data in an easily interpreted format.

Whilst CEMS monitoring captures many stack qualities the data displayed on these web pages relates to stack particulate mass concentration and stack particulate mass flow rate. These two data sets are presented and should be interpreted together to get a full understanding of the possible impact an emission incident may have. Your feedback on how easily this data is understood is welcome.

Dust or Steam?

Members of the community advise us that from time to time, they can see a visible plume coming from our kiln stack(s) and they ask if the plume is steam or dust?
