Element Materials Technology: emissions monitoring specialist

Element Materials Technology is the leading provider of MCERTS-accredited stack emissions monitoring in the UK and Ireland. We provide emissions monitoring and calibration of CEMS at several EfW installations subject to environmental permits issued by their regulatory authorities satisfying requirements of the Industrial Emissions Directive (IED).

The IED aims to protect human health and the environment by reducing harmful emissions, particularly through better application of best available techniques (BAT).

Permit-monitoring requirements will change with the new Waste Incineration BREF BAT conclusions that cover the (co)incineration of waste, including municipal waste, other non-hazardous waste, sewage sludge, hazardous waste, and clinical waste.

Within four years, the environmental permits of all installations involved must be adapted to the new requirements, and emission limit values (ELVs) are set to ensure emissions do not exceed the BAT-associated emission levels (BAT-AELs); these work as a framework for authorities to set plant-specific ELVs.

Regardless of whether the BAT-AELs change or not, all existing incineration installations’ environmental permits need to be reviewed, which may cause changes in plant-specific ELVs.

Future permits will have ELVs based on both IED Annex VI and WI BAT conclusions. New installations must comply with the new requirements immediately without any implementation period.

ELVs will be set in permits to ensure emissions do not exceed BAT-AELs under normal operating conditions, and will apply to daily average values of continuously and periodically monitored substances, and continuous sampling.

Element performs emissions monitoring and in-house MCERTS-accredited analysis of samples, from stack emissions monitoring for periodic compliance and CEMS calibration (EN 14181 QAL 2 and annual surveillance test) to accredited standard reference and approved alternative methods.

Some studies suggest that for many sub- stances, BAT-AELs are set at concentrations that do not allow compliance with the uncertainty requirement of the relevant standard.

It is recognised that there will likely need to be improvements to standard measuring methods which need to be validated at lower concentrations and technical progress in instrumentation.

Element will be continually investing in and developing its emissions monitoring capabilities to meet changing uncertainty requirements and providing guidance on the WI BREF BAT conclusions.
