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.

Excellent facilities, pleasant weather and hospitality attract international teams

Three international hockey teams have used the practice facilities of the university since the beginning of the year to prepare for the Olympic Games in August this year. The German and South African hockey teams have practiced here on four previous occasions.

Due to the cold weather in Europe, Austria also held its hockey training camp at the university this year. In addition, four of Austria’s triathlon athletes used the cross country track and swimming pool on the Bloemfontein Campus to prepare for the Olympic Games.

Germany’s national hockey team practised at the university from 3 to 12 March 2012. South Africa made use of the facilities from 5 to 10 March and Austria’s national team has been practicing in Bloemfontein since 24 February. From 3 to 10 March, a club team from Austria also made use of the university’s facilities, including the astros, the swimming pool, the athletics track and the Biokinetics Centre. SV Arminem also played two matches against the men’s hockey team from Kovsies. The first match end 2-2. With the second match Kovsies won 4-1.

Other international hockey teams who have made use of the astros over the past six years include Russia, Argentina, Belgium, China, Azerbaidjan and the Netherlands.

Staff ensured that everything ran like clockwork during the different training camps. Ms Annemarie Ludick and Mr Frans van der Watt, under the guidance of Mr Mickey Gordon, Head: Institutional Promotion, Fundraising, Marketing and Sport, were responsible for the logistical arrangements and finances. Mr Johan Gerber saw to the maintenance of the astros. The university boasts some of the best equipped astros in the world. “Germany, for example, did not bring along any exercise balls, cones, or beds (for use by physiotherapists) because the astros are fully equipped,” said Ms Ludick.

The fact that international teams such as Germany (ranked second in the world), South Africa and Austria made use of the university’s facilities is significant. “The university’s first team got for example the opportunity to play practice games against these players. The training camps also contributed to the economy of Bloemfontein,” said Ms Ludick.
