‘It is the worst of times, but it is also the best of times because we still have a chance.’
– Sylvia Earl
We have all heard of the term ‘pollution’, but what does it really mean? How do we impact it and how does it impact us? And how do we solve a problem that we aren’t even fully aware of? We are seeing the environmental threat, yet we continue to contribute to the mess?
There are many types of pollution, each with numerous contributing factors. Air pollution results from the burning of fossil fuels and carbon; ecosystems are destroyed by deforestation and overfishing; our lands and waters are being polluted as we continue to dump our everyday waste onto landfills or into rivers and oceans; and then there is the industrial impact of factories and mining. Mining is a material contributor to environmental degradation and indeed the communities that live off them. The video ‘Zimbabwe’s Gold Rush’ on YouTube is an example of what I see all over the African continent.
On the other hand, there are several success stories that demonstrate there is hope on the horizon.
Chile, for example, has had unbearable smog conditions from the burning of wood for warmth during the winter months. The government started replacing firewood heaters with gas heaters, paraffin, or wood pellets, which are not only cheaper but far more energy-efficient than wood. This has resulted in cleaner air during winter and an improved quality of life for citizens.
Deforestation requires drastic action, and Norway, for example, has banned deforestation entirely. As a consequence, Norwegian entities may not deal with international organizations that contribute to deforestation as part of their production process. This type of strict intervention is necessary if we are to make an impact on greenhouse gas emissions, or want to enjoy a flourishing biodiversity in our forests.
When it comes to water pollution, Sweden has implemented industrial wastewater management systems that remove waste and chemicals from water for re-use as fertilizer or biogas. The cleaned water is then returned to rivers and lakes.
Then there is the impact of mining on the environment. The South African government has introduced suitable legislation and our mining industry has responded well. We are seeing more and more evidence of rehabilitation work being performed by companies prior to the mining operation actually being terminated.
A material contribution has come from a company that re-treats residue dumps all around Johannesburg and the Central Rand. The treated material is managed in a far more environmentally friendly way, which significantly reduces toxic seepage into our groundwater. Land is rehabilitated and can be used again for other purposes.
These are only a few examples of the good things that people are doing in respect of caring for and rehabilitating our environment, but while we continue to find new and innovative ways to improve on these efforts, there remains much to be done, including reducing our reliance on coal as a primary energy generator for the southern African region.

President, SAIMM

At the AGM, I spoke about why the SAIMM needs to adapt to a new and more modern mining industry. To this end, we have developed a strategy aimed at repositioning the SAIMM brand in the minds of our members, and indeed all of our stakeholders. There are six key components (or ‘Pillars of Value’) in our overall value proposition, and I intend briefly elaborating on each one of these over the coming months. One of these pillars is the importance of Diversity and Inclusion in the Minerals Industry (DIMI).
We all know that people are different, yet we are not always willing to embrace the rich diversity that this introduces into our industry. Our places of work should be free from any form of discrimination around, inter alia, race, culture, sexual orientation, age, gender, religion, and disability. Our leaders should be able to challenge conventional thinking by exploiting the mix of ideas (i.e. creativity) that usually materialises with the wider variety of skills, experience, and cultural approaches that comes with diversity.
The DIMI Committee is currently chaired by Professor Selo Ndlovu. It is made up of passionate professionals from both industry and academia who are committed to making a real difference. They are particularly interested in the development of students and tomorrow’s leaders. Online webinars, seminars, and workshops will be used to guide and assist students, who are usually unprepared for the range of cultures encountered in the working environment. This will lead to better understanding, better integration, and enhanced performance, which will in turn help us to retain their potential in the mineral industry and more particularly in the SAIMM.
The data also highlights the shortage of registered professional engineers, with only one being available for every 2 800 people living in the country compared to international norms of one engineer for 40 people. This must be a concern, because the ability of our captains of industry to exploit the full potential of our orebodies and supporting resources on a sustainable basis will depend on the quantity and quality of the professional engineers available to them.
