Opus Cactus
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.

Where are they now?

On good days, most of us battle to set our personal finances straight,  let alone be responsible for a large enterprise. So we are extremely proud of the well-trained and talented Kovsie alumni who fill prominent shoes. Operating mostly away from the public eye, they make decisions to improve the economy on various levels. It is heartening to know that the UFS contributes to financial matters and training all across the globe.  

Marina Marinkov


Courses: BCom (Economics), BCom Hons (Money and Banking), and MCom (Economics) (2000-2004)
Current position:
Economist at the International Monetary Fund
Biggest career obstacle: I once worked for an organisation with poor leadership which negatively affected employee morale and job performance. It still proved to be a great learning experience, though. Bad bosses can teach us powerful lessons.
Best career advice:
Stop doubting yourself, work hard and be humble.
Fondest memory of UFS: Time spent on campus with my classmates, whether studying for finals at the library or just catching up between classes. The UFS was also my first employer and I have plenty of wonderful memories with colleagues at the Department of Economics.


Evangelina Nailenge

Courses: BCom Hons (Money and Banking) MCom (Money and Banking) (2005-2006)
Current position: General Manager: Investment Institutions at Namibia Financial Supervisory Authority
Biggest career obstacle: At times, being one of the youngest requires you to work twice as hard to earn your voice and cue at the decision-making table.
Best career advice: “Whatever your hand finds to do, do it with all your might, for in the realm of the dead, where you are going, there is neither working nor planning nor knowledge nor wisdom.” Eccl. 9:10
Fondest memory of UFS: Walking around the campus. Its well-manicured lawns and gardens had a calming effect in the midst of academic pressures. I will forever treasure the moment I first saw my name engraved in the walls of FGG, as the best postgraduate student for both 2005 and 2006.

Vuyelwa Vumendlini

Course: BCom Hons (Economics) (1996-1999)
Current position: Chief Director: Global and Emerging Markets, National Treasury
Biggest career obstacle: Doubting your own capabilities.
Best career advice: The sky is the limit, go for it all out, but most importantly, do something that you are passionate about it. It makes your work much more meaningful.
Fondest memory of UFS: Working as a tutor in my honours year and being able to help other students. I also enjoyed hanging out at Mooimeisiesfontein on Saturday afternoons.


Prof Meshach Azaikpono

Course: PhD in Economics (2004-2008) “The Depth of Financial Integration and its Effects on Financial Development and Economic Performance of the Southern African Customs Union Countries”. He received the Founders’ Medal for the best PhD dissertation in Economics in South Africa.
Current position: Professor of Development Finance, University of Stellenbosch.
Biggest career obstacle: I was fortunate to never have experienced a major career obstacle.
Best career advice: Pursue and focus on your passion.
Fondest memory of UFS: Being a part-time student, I had very limited interaction with the broader university environment. But I really enjoyed the support provided by the library staff and the staff from the Department of Economics. It was always like coming to see friends.


Anton Nicolaisen

Course: BEcon (1986-1989), MBA (1999-2003)
Current position: Provincial Head for the Free State Province, Standard Bank
Biggest career obstacle: Earlier in my career, I fell into a comfort zone and had to acquire the willingness to change.
Best career advice: Continuously challenge yourself to be the best possible person you can be, and run your own race. Learn through difficult times, and be open to change.
Fondest memory of UFS: Although I was not the biggest academic, I enjoyed interacting with lecturers … their stories and unique characteristics. Back then, I interpreted some as funny or awkward, only later did I realise how much I had learned from them. And of course, I’ll always remember the team spirit at athletics meetings and intervarsity.
