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.

Almost 2000 degrees and diplomas conferred at Winter Graduation
2015-06-26

Live streaming will be available on: http://livestream.ufs.ac.za/

The 2015 Winter Graduations are almost underway. The highlight on the university calendar for every graduate will take place on the Bloemfontein Campus on 1-2 July 2015. On 1 July 2015, diplomas will be awarded by the Centre of Financial Planning Law (331 in total) and the School of Open Learning (376 in total). On 2 July 2015, a total of 1 220 master’s and doctoral degrees will be awarded to graduates from all seven faculties.

A highlight at this year’s Winter Graduation is the awarding of three honorary degrees by the university. Ambassador Lakhdar Brahimi, Dr Mercy Oduyoye and Mr John Samuel will receive honorary degrees.

On 17 August 2012, Ambassador Brahimi was appointed by the United Nations as the new peace envoy to Syria, replacing Kofi Annan. He is also a member of the Commission on Legal Empowerment of the Poor, the first global initiative to focus specifically on the link between exclusion, poverty and the law. Prof Heidi Hudson, Head of the Centre for Africa Studies at the UFS, will receive the honorary degree on his behalf.

Dr Oduyoye is widely regarded as one of the most influential women theologians Africa has produced in recent history. Currently, she directs the Institute of African Women in Religion and Culture at the Trinity Theology Seminary in Legon, Ghana.

Mr John Samuel, who will receive an honorary award, is also scheduled to be a guest speaker at the two ceremonies on 1 July 2015.

Wednesday 1 July 2015:

John Samuel will be the speaker at both ceremonies. He is one of South Africa’s leading education experts with international and national experience, covering a period of more than forty years. He was involved in the founding of the South African Campaign: Public Participation in Education Network (PPEN), established the Centre for Education Policy Development, the Joint Working Group (for The National Party Government and the ANC), the National Education Conference, and the National Education and Training Forum. He also made leadership contributions to the First Education and Training White Paper, the Transformation Strategy for the National Education Department, and the first Green Paper on Higher Education.

John is also Senior Programme Director of the WK Kellogg Foundation in the USA. He has also been the Chief Executive of the Nelson Mandela Foundation, and the CEO of the Oprah Winfrey Leadership Academy for Girls.

Thursday 2 July 2015:

Nataniël will be the speaker at both ceremonies. Nataniël is a singer, songwriter, and South African entertainer, who has crossed from the alternative circuit to the stage. For the past 10 years, he has become well-known for his outspoken Kaalkop column in SARIE magazine. His solo career was launched in 1987 and, since then, he has released 16 albums, staged more than 70 original theatre productions, and published 15 books. Over the past two decades, Nataniël has gained the title of South Africa’s leading exponent of the solo stage act. He manages Kaalkop Studio, his lifestyle retail company, and records on his own independent label, Nataniël House Of Music. He is an ambassador for Child Welfare SA, and also heads his own charitable foundation, The Nataniël Progress Project.
