Sasolburg
In Sasolburg, key air quality initiatives were
successfully implemented. Local small, medium
and micro enterprises (SMMEs) continued to
provide waste recycling services, community
waste skips were regularly serviced, and vehicle
emissions testing was introduced following
the retraining of municipal staff. Vegetation
management was resumed in collaboration
with the municipality during the winter season,
with a structured handover of previously
Sasol-managed areas to ensure sustainability.
Road construction projects within the community
areas, initiated in April 2025, were completed
at the end of June 2025. Additionally, the
commercialisation of low-smoke coal stoves,
developed in partnership with North-West
University, progressed steadily.
The community education and awareness
campaign was expanded to include early
childhood development centres, extending
the programme’s reach and impact.
Secunda
In the Lebohang area of Secunda, phase two
of the housing insulation and liquified petroleum
gas (LPG) rollout continued. Since October 2024,
four local SMMEs were onboarded, 239 homes
were upgraded and handed over to the owners
with an additional 44 houses completed by the
end of June. Sasol’s environmental education
campaign reached approximately 15,000
households through door-to-door outreach,
enhancing awareness of clean energy and
air quality.
These initiatives reflect Sasol’s continued
commitment to improving air quality in partnership
with local communities and stakeholders.
Sasol has achieved significant milestones in air quality
management, delivering on our commitment to environmental
compliance and sustainability.
• Since 2018, we have invested nearly R16 billion in
environmental initiatives, with approximately R10 billion
dedicated to air quality projects – highlighting our focus
on reducing emissions and improving air quality throughout
our operations.
• We retrofitted 27 boilers with particulate matter abatement
technology. These installations were part of a comprehensive
programme to meet regulatory requirements and enhance
operational reliability.
KEY ACHIEVEMENTS INCLUDE THE FOLLOWING:
Particulate Matter (PM) emission
reduction
At SO:
• More efficient transformers were installed
on the ESPs of all the boilers.
• The Synfuels catalytic cracker’s PM
abatement system was completed and
commissioned during November 2024.
At SNO:
• At the Steam Station plants, we upgraded
ten of the 12 ESPs as at the end of
June 2025, while two boilers have been
decommissioned.
• The upgrade of the carbon monoxide
boiler – enabling sustainable compliance
with the PM emissions limits from the
fluidised catalytic cracking unit – at Natref
has been successfully commissioned.
Nitrogen Oxides (NOx) emission reduction
At SO:
• 15 coal-fired boilers were retrofitted with
low NOx burner (LNB) abatement technology
to align with the MES for new plants.
• LNBs were installed on two gas turbines
during FY25.
At SNO:
Decommissioning of incinerators
• Upgrades were completed on nine boilers, as at
the end of June 2025.
At SO:
• Two boilers were decommissioned due to lower
regional steam demand. The remaining boiler
is scheduled for abatement during the second
quarter of FY26.
Sulphur Dioxide (SO₂) emission reduction
• Implementation of a turndown boiler strategy
enables compliance with load-based SO2 emission
limits at Secunda Operations.
• Coal blending has been implemented at SNO to
ensure that the SO2 emissions remain compliant
with licence requirements.
Volatile Organic Compounds (VOC) reduction
At SO:
Significant progress has been made in reducing VOC
emissions, contributing to improved air quality and
compliance with environmental standards.
• The installation of internal floating roofs were
completed on two tar tanks the third and final
tank is in construction.
• At the Phenosolvan unit, VOC emissions from the
sandfilters and depitchers were abated via the
regenerative thermal oxidisers.
SASOL INTEGRATED REPORT 2025
78
• The four bio-sludge incinerators were
decommissioned prior to 1 April 2025,
with commissioning of the thermal lysis units
and facilities facilitating alternative waste
treatment methods.
• The high organic water project was completed
to divert the stream from incineration and
route it to the existing bio basin infrastructure
for treatment.
At SNO:
• Thermal oxidation incinerators remained
non-operational, with higher hierarchy waste
management solutions under consideration.
Low-carbon boilers
Natref progressed the implementation of its
low-carbon steam supply project to secure a
reliable, self-generated steam supply for
operations. The project includes installing
three high-pressure steam boilers powered by
advanced, energy-efficient technology. The
system will cut coal-derived steam imports
to zero – driving a reduction in Natref’s
greenhouse gas emissions.
