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.

Breeding of unique game requires a balance between conservation and sustainable use

2014-05-20

Game bred for qualities such as unconventional hair colour or horn quality, may on the long term have unexpected consequences for biodiversity and game farming.

This is according to the inaugural lecture of Prof Paul Grobler from the Department of Genetics at the University of the Free State (UFS).

Prof Grobler feels that the consequences of selective breeding should be examined carefully, as there is currently much speculation on the subject without sound scientific information to back it.

“At the moment, colour variation invokes much interest among game farmers and breeders. Unusual colour variants are already available in different game species. These unusual animals usually fetch much higher prices at auctions compared to prices for the ‘normal’ individuals of the species.”

Examples of these unusual variants are springbuck being bred in white, black or copper colours, the black-backed or ‘saddleback’ impala, and the gold-coloured and royal wildebeest.

A black-backed impala was recently sold for R5,7 million.

“Based on genetic theory, good reason exists why these practices need to be monitored, but one should also take care not to make the assumption that selective breeding will inevitably lead to problems,” warns Prof Grobler.

Grobler says that negative characteristics in a species can sometimes unwittingly be expressed during the selection process for a unique colour. “It is seen, for example, in purebred dogs where the breeding of a new race sometimes brings underlying genetic deviations in the species to the front.” He also believes that some of these animals may not be able to adapt to changing environmental conditions.

“However, one should also look at the positive side: because of the good demand for game, including unusual variants, there is much more game in South Africa today than in many decades. Balance should be found between the aims of conservation and the sustainable utilisation of game.”

Research at the UFS’s Department of Genetics is now trying to establish the genetic effects of intensive game breeding and predict the impact on biodiversity.
