AIR QUALITY OFFSETTING PROGRAMME
AIR QUALITY ABATEMENT ACHIEVEMENT: PROGRESS OVER THE LAST YEAR
AIR QUALITY ABATEMENT ACHIEVEMENT:
TOWARDS 2025
We are committed to implementing the second
phase of our offsetting implementation plan which
is focused on the reduction of PM and SO2 pollution
in the surrounding communities.
In FY23, we progressed with the implementation of our air quality compliance roadmap, with the
following achievements:
PMs, NOx, SO2, VOCs
The plan includes a comprehensive education and
awareness campaign, covering the public and
schools. The school awareness campaign
consisted of 26 primary schools within the
communities of Govan Mbeki Local Municipality.
The campaign created a positive impact as learners
were introduced to in-depth concepts of air quality.
Engagements sessions and door-to-door campaigns
were conducted for 1 552 households for Embalenhle
and 2 400 for Lebohang. The impact of the
programme was bolstered by the publication of
these relevant topics, in local newspapers, in three
regional languages.
SEO's offset programme made good progress in
2023. It included the construction of a 1.6km road
in the Zamdela area, with an aim of reducing dust
pollution (particulate matter) associated with
vehicles travelling on the road. SEO and Natref cut
about 4.4 million m2 of grass and removed some
1 040 ton of biomass around the Sasolburg area.
This resulted in avoiding approximately 6.6 tons
of PM10, 5.2 tons of PM2.5 and 0.62 tons of SO2
emissions. Similarly,around 3 080 tons of domestic
waste was removed resulting in approximately 21.27
tons of PM10, 22.5 tons of PM2.5 and 2.95 tons of
SO2 emissions being avoided.
PM EMISSION REDUCTION
Improvements for PM reduction within Secunda, Sasolburg and Natref Operations include:
" At SO, we retrofitted 12 out of 17 ESPs and recorded an improvement of 17,6% from 2022; and
" At SEO9s Steam Station plants, we upgraded seven of the 12 ESPs, with one boiler being retrofitted at
our Steam Station 1 plant.
NOx EMISSION REDUCTION
" Three additional low NOx retrofits at our boiler fleet were completed during the reporting year at SO,
with the roll-out of the remainder of the fleet on track to be fully compliant with the MES limit.
" At SO, low NOx burners were installed on six of the 12 operational boilers, with two low NOx burner
installations currently in progress.
TOTAL VOLATILE ORGANIC COMPOUNDS (TVOC) REDUCTION
As part of Sasol9s overall VOC-reduction roadmap, we completed the SO TVOC drains project,
commissioning and reaching beneficial operations was achieved in all four phases of the project.
SO2 EMISSION REDUCTION
Our boiler turndown plan will result in reducing our demand for boiler coal, thereby realising the potential
to reduce our sulphur dioxide load release into the receiving environment. WWW For more information refer to
NAQO's decision on our Clause 12A appeal together with our response www.sasol.com/node/6026.
INCINERATOR REDUCTION
We continue to review the sustainable alternative method to incineration for the handling of the
Sasolburg waste streams.

We are on track with our air quality compliance
roadmaps to achieve compliance with the new
plant standards in 2025:
" Installing low NOx burners on the remaining
coal-fired boilers in SO and SEO aimed at
reducing boiler NOx emissions;
" Installing high-frequency controllers on the
ESPs of the remaining boilers in Secunda and
Sasolburg to reduce PM emissions;
" Installing abatement equipment at the
Synfuels catalytic cracker stack within SO;
" Streamlining of SO blending facilities to meet
the SO2 standard at SEO;
" Installing VOC abatement equipment at the
crude tar tanks within SO;
" Reducing hydrocarbon releases from our
phenosolvan and depitcher vents;
" Abating hydrocarbon release to atmosphere
via the coal tar filtration west stack at
Secunda;
" Finalising the routing of the biosludge from
incineration to gasification;
" Confirming the sustainable alternative
method to incineration for the handling of the
Sasolburg waste streams; and
" Finalising solution for our HOW waste stream.
