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.

Physical Planning lives in recaptured space
2014-06-18

When the Department of Physical Planning decided on a new office premises, the team decided to tackle the project with an overarching theme – recycling.

It is important for Physical Planning to not only dictate to other departments on campus, but to set the example themselves,” says Nico Janse van Rensburg, Director: Physical Planning at the UFS. 

Recaptured space

New office space on campus is simply not available. It was therefore decided to recover space and a store room was identified. “Fortunately, the storage area had ceilings. However, it was dilapidated and was sagging all over. To divert attention from the ceiling, we painted it in a dark colour and the walls white.

“All wiring was also done superficially. It draws the attention away from the uneven surfaces and simplifies work on the wiring. Instead of trying to hide it, we made a focal point of it,” says Janse van Rensburg.

Recycled building materials

Lots of the building material that was used to convert the storage space into offices, was recovered from other building projects on campus. Material that would normally be discarded was utilised creatively to not only serve a practical purpose, but also an aesthetic one.

A laboratory basin was used as wash basin. Remaining parts of granite slabs from other sites were utilised as top for the basin. Existing toilets were also reused. To enhance the atmosphere, new taps in an affordable, but durable range were installed.

Recycled furniture

We rambled through every possible store room to find furniture. Tables were simply sanded and varnished and look better than new. Even the cabinet at the entrance was saved from wind and weather and reused.

Hot and smart

Only one screen wall was built. It was left in raw brick, unplastered and unpainted to contribute to contrasting textures. Existing walls were left painted or unpainted as it was before.

“The environment that was created breaks down several existing perceptions. Such as the perception that everything has to match; everything has to be plastered and painted and many others. This is an example of how different materials can be combined to create a lively environment.

“Staff members have already moved into their new offices and are very satisfied,” says Janse van Rensburg.
