Prof Maryna Boshoff from the Department of Sustainable Food Systems and Development, Lerato Mamabolo (UFS graduate, now employed at OPUS Cactus), and Sotirios Pilafidis, Head of Research and Development at OPUS Cactus, at the XI International Congress on Cacti as Food, Fodder and Other Uses, hosted by the FAO-ICARDA CactusNet in Tenerife, Canary Islands.

The University of the Free State (UFS) has formalised a collaboration with OPUS Cactus, a pioneering biotech company focused on sustainable cactus-based farming and biorefineries in semi-arid regions. This partnership builds on OPUS Cactus’ expansion at the historic Waterkloof Research Station near Bloemfontein and combines the UFS’ academic expertise with industry innovation to promote climate-smart agriculture and economic development.

OPUS Cactus, led by Joeri van den Bovenkamp-Hofman, CEO, and Sotirios Pilafidis, Head of Research and Development (R&D), specialises in transforming marginal, non-arable land into productive, resource-efficient ecosystems by cultivating the drought-tolerant Opuntia cactus. This versatile biomass supports renewable bioenergy, animal feed, food production, fermentation feedstock, and sustainable biomaterials, while contributing to carbon capture and climate mitigation efforts.

“Our mission is to unlock the full potential of Opuntia biomass for sustainable bioenergy, food, and biomaterials, advancing regenerative agriculture and climate action,” says Van den Bovenkamp-Hofman. OPUS Cactus operates dual hubs: its headquarters and R&D lab in Groningen, the Netherlands, and the flagship 1 000-hectare Waterkloof Research Centre in the Free State. The Waterkloof facility serves as a commercial farm, research platform, and demonstration site for regenerative farming techniques.

The UFS collaboration involves multiple departments, including Sustainable Food Systems and Development, Soil, Crop and Climate Sciences, and Microbiology and Biochemistry. Profs Maryna Boshoff and Carlien Pohl-Albertyn, alongside Dr Gesine Coetzer, provide academic leadership in the partnership.

Prof Boshoff explains, “This industry-academia collaboration aims to develop innovative projects utilising cactus-based products. It builds on decades of cactus research at the UFS, enabling the translation of scientific knowledge into real-world impact through scale-up and commercialisation.”

 

Bridging academic research and commercial innovation to promote climate-smart agriculture

At the core of the partnership is the Waterkloof Research Centre, home to 42 spineless Burbank cactus pear cultivars. The facility acts as a ‘living laboratory’, integrating empirical research with commercial-scale farming. “Waterkloof now offers students and researchers access to operational infrastructure that cannot be replicated in conventional academic settings,” says Prof Boshoff.

Continuing projects at Waterkloof include biogas production through an anaerobic digester, regenerative agriculture practices such as cover cropping and reduced tillage, advanced plant biotechnology to breed superior cultivars, fermentation research for alternative proteins, and the development of novel fermented foods and sustainable biomaterials.

The collaboration also plays a critical role in conserving Opuntia genetic diversity and evaluating cultivars across South Africa’s varied agro-ecological zones. “Research done by UFS and ARC scientists on cultivar selection and cultivation is applied and scaled up through OPUS Cactus’ commercial operations,” Prof Boshoff adds.

This partnership provides valuable hands-on experience and career pathways for postgraduate students and young researchers. “We offer internships and employment opportunities, with several recent UFS graduates already joining our R&D team,” says Pilafidis. “We actively seek motivated graduates passionate about sustainable agriculture and bioengineering.”

By converting semi-arid landscapes into productive, carbon-sequestering ecosystems, the UFS-OPUS Cactus collaboration exemplifies how scientific innovation, entrepreneurship, and environmental stewardship can drive climate resilience, food security, and sustainable economic growth.

“OPUS Cactus is a win for the environment, communities, and business alike,” concludes Van den Bovenkamp-Hofman.

UFS launches history book
2007-02-02

 

Attending the launch of the UFS history book were, from the left: Prof Stef Coetzee, Prof Francois Retief, Prof Wynand Mouton, Mr Pieter Cox (Chairperson on Sasol) and Prof Frederick Fourie (Rector and Vice-Chancellor of the UFS). Profs Coetzee, Retief and Mouton are former rectors of the UFS.
UFS launches history book
 
The University of the Free State (UFS) today launched its history book titled, From Grey to Gold, on the Main Campus in Bloemfontein.
 
“The history of the UFS is one of faith, hope, struggle and determination. The book tells a fascinating story that stretches over a 100 years. It is divided into five main phases, which tells about the growth of the UFS from a poor Free State community to a mature university. Interesting stories about student days, sport, rag and hostel activities are included in each phase,” Prof Frederick Fourie, Rector and Vice-Chancellor said during the launch of the book.
 
“One cannot know where you are going if you don’t know where you are coming from. You have a clearer idea of the issues facing an institution if you know the history. A book like this one is also an important source of reference for staff on the campus,” said Prof Fourie.
 
The first research for the book was done from 1999-2003 by Prof Leo Barnard from the Department of History and a team of researchers. They also compiled the first manuscript. 
 
During the last three years, Prof Fourie was closely involved with the writing of the final phase and finishing off the history book project. “It was an honour to be so closely involved with the story of the UFS because now I have a better understanding of the institution, its people, its culture and its way of thinking. For any rector of a university, such an understanding of its institution is a requirement,” Prof Fourie said.
 
The book is partly sponsored by Sasol. During the launch of the book, Mr Pieter Cox, Chairperson of Sasol said the company and the UFS have been partners for 57 years. “Both Sasol and the UFS are striving for excellence – Sasol for excellence in technology and the UFS for excellence in education,” said Mr Cox. 
 
“It was an easy decision when the UFS approached Sasol for financial support of the history book. Its a formidable piece of work, something Prof Fourie and the UFS can be proud of,” said Mr Cox.
 
The book consists of more than 500 pages with hundreds of photos and a wide range of supplements of office-bearers, awards and achievements (including national and sporting colours). A timeline framework, putting the history of the UFS in context with the history of the Free State, South Africa and of the world, is also included.
 
Besides the supplements, the history book also tells the story of amongst others the establishment of the UFS; the role of its founding fathers; black pioneers of transformation; the establishment and development of academic departments and faculties; student numbers; pioneers and trends in research; academic entrepreneurs; campus issues and campus politics; interesting facts and stories about student life (rag, intervarsity and cheerleaders, sport and the Springboks, hostel traditions); the admission of black students and anguish about race; language and culture; the development of the Main Campus; the Tickey and the Banana and much more.
 
Emphasis is placed on a very high level of quality. “It is not every day that the university becomes hundred years old and the institution will be measured by the quality of the book. We cannot say the UFS is a university of excellence if the book does not reflect that,” Ms Edma Pelzer, Director: Physical Resources and Special Projects said. Ms Pelzer managed the project as part of the last mentioned part of her portfolio.
 
The search for photographs was an important aspect of the book and it was a big task to find photographs and write captions. It took almost a year to translate and prepare the English edition and almost ten months to ensure the accuracy thereof, especially to correctly translate the typical Free State and UFS terminology and naturally to complete the English manuscript’s layout and proofreading. In the mean time the cover pages were designed and in September 2006 the manuscript went into the final print process. The Afrikaans title is: Van Sink tot Sandsteen tot Graniet.  
 
The cost of the book is R380 per copy. Those who already ordered the book will soon receive their copy. Orders can be placed by contacting Mr Dawid Kriel at UFS Marketing on 051 401 3409 or on the UFS web site at www.ufs.ac.za. The book is also available at Van Schaik Book Store on the Thakaneng Bridge, UFS Main Campus and at Fascination Books in Mimosa Mall, Bloemfontein.
