We manage the impacts of our waste streams by aligning our policies and procedures with sustainability principles and leading practice. We are transforming our business into a circular mining economy so that the waste we produce is reused and recycled with sustainable benefits for host communities that depend on Exxaro for their livelihoods.
By recycling and reusing the waste we produce, we uphold our licence to operate with a cradle-to-cradle approach that minimises waste production.
Exxaro understands that our sustainability journey should embrace the cradle-to-cradle principle where we can attain zero waste operation. We are evaluating the opportunities presented by the circular economy concept which focuses effort on the management of material to eliminate the need to dispose of unused material. Cradle-to-cradle waste management is a closed cycle: waste from one process is used in other processes to encourage elimination or minimisation of waste.
Exxaro's BUs apply the "avoid, reduce, reuse and recycle" waste management hierarchy to prevent and avoid waste as much as reasonably practicable. Exxaro is working on initiatives such as:
Exxaro's evolving environment policy and management standard for hazardous and non-hazardous waste governs our approach. We ensure prevention, minimisation, reuse, recycling, energy recovery and safe waste disposal in compliance with the National Environmental Management: Waste Act, 2008 (Act 59 of 2008) and supporting legislation.
We regularly review the policy and management standard to ensure relevance and alignment with legislation. As requested by our investors, we are set to release individual policies, separate from the overarching environment policy, for waste management and related disciplines in 2023.
Our management procedures include waste classification and efficiency reporting, as required by waste management licences, informed by sustainability KPIs aligned with ESG indices to drive continuous improvement.

In line with leading practice, Exxaro supports the proximity principle (treat and dispose of waste in reasonable proximity to the point of generation), duty of care (we are ethically responsible for waste management) and the precautionary principle (we are proactive in mitigating environmental risks).
BUs are responsible for managing their general and hazardous waste. General waste comprises:
BUs manage hazardous waste and report volumes monthly. Examples of hazardous waste emanating from our operations include used oil, contaminated soil, medical waste, used personal protective equipment and sewage. In compliance with the South African Waste Information System, sites producing more than 20kg/day of waste are registered and maintain compliance certificates. As we do not have on-site waste treatment processes, we receive the certificates when certified contractors take hazardous waste (including used oil, hydrocarbons and sewage) to licensed facilities. Medical professionals manage waste produced by on-site clinics at Matla and Grootegeluk.
Material waste at Cennergi's facilities includes general waste, oil rags and used oil. Cennergi implements waste separation at source to increase recycling, where possible, and minimise waste sent to landfill.
|We pursue innovative waste handling, transportation and disposal solutions at Grootegeluk where a waste tyre processing contractor assists in converting used tyres into reusable material in compliance with legislation and to reduce our liabilities.|
Exxaro stores used off-the-road tyres in a facility with controlled access, stacking plans and fire prevention measures at Grootegeluk before removal by a specialist recycling contractor for beneficial reuse:
The success of the Exxaro project elicited further corporate participation with all stakeholders such as government, local communities and other mining industries. This is the first time in the mining industry that such a project was conducted, giving Exxaro an opportunity to lead in waste tyre management. The project was rolled out at Leeuwpan to remove its waste tyres. The project also showed that while mining will impact an area, a responsible approach enables us to meet our commitment to sustainability and reduce long-term environmental liabilities while operating the mine.
To expand the Grootegeluk waste tyre management initiative with a service that will benefit South Africa's mining industry, we are evaluating proposals to establish an integrated waste management facility in Lephalale, Limpopo. The Impact Catalyst was appointed to conduct the prefeasibility study for the integrated waste management solution.
Further to this, we pursue responsible waste management through:
Our sustainability managers, supported by on-site environmental specialists, under the leadership of the executive head: sustainability, oversee the implementation of our policy and practices at operations.
As part of Business Unity South Africa, we approached the DFFE to address our concerns about the definition of waste in the National Environmental Management Laws Amendment Act, 2022 (Act 2 of 2022). On 27 June 2022, the DFFE agreed to send an explanatory note with government's definitions that would assist proposed sectoral engagements.
In its grievance register, Exxaro did not report any waste grievances, fines or penalties and did not receive any environmental fines and penalties related to non-compliance on waste management during the financial year.
General waste recycled decreased by 9% to 2 768t (2021: 3 018t) due to less ferrous and non-ferrous scrap produced at Grootegeluk.
Hazardous waste sent to landfill (t)
|General waste recycled (t)||2022||2021||2020|
|Ferrous and non-ferrous scrap||2 620||2 950||2 860|
|Total||2 768||3 018||2 914|
The total weight of hazardous waste generated at our managed coal operations and sent to landfills in 2022 increased by 68% to 1 624t (2021: 520t) due to clean-up operations in May, June and August at Grootegeluk. This resulted in a 30% increase in the amount of hazardous waste taken away and disposed of in a registered landfill.
|Waste management in 2022|
|Head office||Renewed contracts for recycling and general waste disposal at head office|
|Grootegeluk||Completed the fire protection system installation in the temporary waste tyre storage area and stacked tyres as per the approved layout at Grootegeluk||
|Matla||Began appointing a new service provider (currently TL Ideas, an ESD beneficiary) to manage our waste recycling station at Matla|
|Leeuwpan||Took ownership of the optimised sewage treatment plant at Leeuwpan|
|Belfast||Appointed Phambili Services, an ESD beneficiary, to manage general and hazardous waste|
Cennergi's operation and maintenance contractors are responsible for waste management at both wind energy facilities. Cennergi did not report any waste grievance, fines and penalties during the year.
We will optimise our 2023 reporting to set targets that will enable us to divert 80% to 85% of recyclable waste from landfill sites by 2025. We plan to use alternative waste reduction or avoidance technologies and opportunities to procure equipment that supports our commitment to the circular economy concept.
At Grootegeluk, we will continue the successful waste tyre reclamation project with a new service provider, establish partnerships with other NGOs and seek access to additional project funding.
As advised by FTSE Russell, we will include additional KPIs in our reporting.
Our new waste management policy will be approved and published in 2023. The policy outlines waste reporting, management and mitigation. Detailed procedures and KPIs will ensure we honour our commitments. The dashboard that tracks waste volumes generated, recycled and sent to registered landfills will include KPIs such as total costs of environmental fines and penalties, as recommended by FTSE Russell. This will enable us to improve our disclosure.
Assessments across our operations determined the scope of work needed to achieve these targets. Data collected on recyclable materials from the waste stream assessments will optimise our 2023 reporting.
