From mining impact to environmental solutions

Only 16% of plastic gets recycled in South Africa, despite technological advancements. While the Extended Producer Responsibility (EPR) Regulation of 2021 assigns post-consumer recycling responsibility to producers, substantial efforts are needed to develop effective waste management strategies, heighten public awareness, discover practical solutions, and hold plastic-producing companies accountable.

Prioritising environmental sustainability

Dr Maryam Amra Jordaan co-founded SA Rebuilders with her husband, Yasar Amra, in 2016. By combining 3D printing, chemistry, and plastic recycling, they tackle socio-economic issues while prioritising environmental sustainability. As the daughter of a miner from Kimberley, Dr Jordaan is committed to mitigating the negative effects that industries have on the health, environment, and social aspects of local communities. She was honoured with an Alumni Cum Laude Award from the University of the Free State (UFS) for her work in this regard.

Dr Jordaan’s academic journey at the UFS from 2001 to 2013 includes a BSc in Chemistry and Physiology, BSc Honours, MSc, and a PhD in Organic Chemistry. She dedicated five years to lecturing and research on the Qwaqwa Campus and four years at the Mangosuthu University of Technology (MUT). During this time, she authored 19 pharmaceutical and environmental chemistry research papers and won numerous national and international awards. She entered the UFS with dreams of assisting in some way and ended up helping to solve the Sustainable Development Goals (SDGs).

“Remarkable potential for rapid prototyping and supply chain resilience through digitisation exists, but the current energy crisis hampers the full realisation of 3D printing’s potential,” Dr Jordaan explains. Added to this, is the complex endeavour of becoming a 3D engineer. “Expertise in materials science and project management is equally essential. Creativity, quick learning, and meticulous attention to detail are all characteristics necessary to excel as a 3D engineer.”

Seeking out biodegradable product alternatives

Dr Jordaan stresses the need for effective waste management, awareness, practical solutions, and accountability for individuals and plastic-producing companies. Therefore, she promotes reusable and recyclable shopping bags, among others, and instils this behaviour in her children. The Amras actively seek out biodegradable product alternatives, as they are fully aware of the environmental impact of the manufacturing industry.

They incorporated this ideology in the manufacturing process of organic butter by transforming the plastic waste from this process into a 3D filament. This product is currently undergoing SABS testing, after which it will be available to the local market.

Two scientists part of team that discovers the source of the highest energy cosmic rays at the centre of the Milky Way

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
