Stack Emissions Testing

how it works

Yellow Tree conducts emissions testing from the boiler and process stacks of many industries in Southern Africa. We have tested refineries, foundries, sawmills, incinerators, power stations, food and beverage facilities and so many more.

We understand the South African listed activities intimately. We are able to test for all of the pollutants that are listed in the legislation including Particulate Matter (PM), SO2, NOx, CO, HCl, HF, NH3, Heavy Metals, TVOC’s – and even dioxins, furans and PAH’s!

Who can I speak to?

Francois oversees new business development and can help you define your emissions testing requirements and quote accordingly.

Consolidated Emissions Results

With our multiple testing teams and short lead times, we can conduct testing at all of your sites nationwide and provide consolidated feedback to head office. Our reports are comprehensive and simple to understand, even for non-technical people.

Engineering Advice

Our service doesn’t end when we hand over the report. We will meet with you to discuss ways to reduce emissions and to obtain compliance. We can also conduct upstream and downstream measurement to determine the abatement efficiency.

The Bridge Between You and Law

We know the legislation well. We will sit with you and share how the legislation applies to your site. We can assist you with your Atmospheric Emissions License (AEL), NAIES and Annual Reporting. And we can help you build a relationship of trust with your Air Quality Officer as we have worked with many of the AQO’s in SA.
