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.

Central SRC constitution for UFS approved by Council
2005-07-20

University of the Free State Fact Sheet

1. The Council of the University of the Free State (UFS) on 10 June 2005 unanimously approved the establishment of a Central Student Representative Council (CSRC)  to constitute a legitimate basis for the democratic participation of students of all three of its campuses in the governance of the university.

2. In a major breakthrough and transformation step for student governance, the Central SRC will include representatives of the main campus in Bloemfontein, the Vista Bloemfontein campus and the Qwaqwa campus of the UFS.

3. The need to establish the Central SRC follows the incorporation of the Qwaqwa campus into the UFS in January 2003 and the incorporation of the Vista campus in Bloemfontein into the UFS in January 2004.

4. The constitution of the Central SRC is the outcome of a consensus reached during a lengthy process of negotiation between the SRCs of the three UFS campuses, indirectly involving diverse student formations such as Sasco, ANCYL, YCL, Pasma, SASO, SADESMO, AZASCO, SCO, HEREXVII, KovsieAlliance, ACDP, etc. Independent constitutional and political experts facilitated key parts of the negotiation process.

5. In this process, the UFS management went out of its way to ensure the participation of all student formations, especially Sasco and the ANC Youth League, as well as the duly elected SRC officials of the three campuses.

6. With the establishment of a Central SRC, the UFS has adopted a federal student governance model whereby the CSRC is the highest representative student body on matters of common concern for all students. The three campuses of the UFS will retain SRC structures for each campus with powers and responsibilities for matters affecting the particular campus.

7. The central SRC will have 12 members made up of delegates of the different campus SRCs, including the presidents of these three SRCs. In total, the main campus will have 5 representatives, the Qwaqwa campus will have 4 representatives and the Vista campus will have 3 representatives. This ratio ensures a strong voice for the smaller campuses in the central SRC.

8. This arrangement will be reviewed after a year to make allowance for the phasing out of undergraduate (pipeline) students at the Vista campus, as was agreed in the negotiations preceding the incorporation of that campus into the UFS.

9. From these 12 members a central SRC president will be chosen on a quarterly basis to represent the general student body at Executive Management, Senate and Council.

10. The historic official inauguration of the first Central SRC is scheduled to take place in early August 2005.

11. This event, like the adoption of a broadly negotiated new constitution for the main campus SRC, represents a  breakthrough in that all three campus SRCs delegations and all relevant student organizations have been part of the process and have accepted the outcome of the process.
