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.

Various stakeholders pledged their support to the newly-appointed Vice-Chancellor and Rector of the University of the Free State (UFS), Prof Francis Petersen, during the first in a series of welcoming events that was held at the Qwaqwa Campus on Thursday 11 May 2017.

A message of support and welcome from the Paramount Queen of the Bakoena Royal Council, Mofumahadi Mathokoana Mopeli, took everybody in attendance back three decades to the time when the campus was first established.

“The Qwaqwa Campus of the then University of the North was created to swell this area and the broader Eastern Free State with intellectual capacity,” she said.

“It is with this in mind that we encourage you, Prof Petersen, to continue upholding the best of your predecessors. Search for what they could not achieve and learn from that. Traditional leadership in this area will always be a friend to the university,” she added.

The Thabo Mofutsanyana Education District was represented by the Acting District Director, Lindiwe Mabaso, who expressed the district’s pride in being associated with the university.

“Our district is excelling in Mathematics and Science, and this can be attributed to the educators that we get from the Qwaqwa Campus. We are proud to say that we are number one nationally when it comes to Mathematics and Science, and this is through the support we get from the campus. Our schools will continue to be centres of excellence under the new leadership of Prof Petersen,” she said.

Staff and students weigh in

Both Nehawu and Uvpersu expressed their optimism in working with Prof Petersen.

Branch chairperson of Nehawu, Teboho Pitso, said the union appreciated the fact that Prof Petersen was taking over the leadership of the institution at a very difficult time, both institutionally and nationally.

“As workers, we are faced with a lot of challenges and we hope that none of us will be retrenched under your leadership,” he said to an appreciative audience consisting of various internal and external stakeholders.

Acting Chairperson of UVPERSU, Khethiwe Biyo, said the workers’ union was happy that Prof Petersen believed in teamwork.

“Your commitment in working with us is appreciated. We look forward to learning from you about institutional innovation,” she said.

Students were represented by the Qwaqwa Campus SRC President, Njabulo Mwali, who expressed the need for a deeper and detailed transformation process.

“Your expertise and skills have set you above all other aspirant applicants for this position, and we hope that we will learn a lot on this journey,” he said.

“We at the UFS are actively, intentionally,
and continuously engaged in promoting
diversity.”

"Ensure fairness" 

In his response, Prof Petersen emphasised the importance of inclusivity and innovativeness. He said, “Staff and students at the three sites of learning must do all they can to ensure that the UFS realises its goal of being an inclusive institution, one that provides equal access and opportunities to everyone, makes a conscious effort to prevent discrimination, and ensure fairness.”

“Being committed to inclusivity means that we at the UFS are actively, intentionally, and continuously engaged in promoting diversity. This diversity is expressed through our people and through the curriculum, and in the way we work with our communities to promote awareness, empathy, and understanding of the complex ways individuals interact. As you know, our ultimate goal as a university is not only to educate young people up to the point that they graduate. What they learn during their time with us should help shape them into people who can think innovatively in order to address the challenges that face us in the 21st century,” he said.

The Qwaqwa Campus Chorale and the award-winning choir from The Beacon Secondary School in Phuthaditjhaba provided the entertainment.

Similar events will respectively be hosted on the South and Bloemfontein Campuses on 18 and 19 May 2017.
