At the launch of NovaLogix, a company co-owned by the UFS and ZZ2, were, from the left, Dr Tommie van Zyl, CEO of the ZZ2 Group, and Prof Philippe Burger, Dean of the Faculty of Economic and Management Sciences, and Prof Francis Petersen, Vice-Chancellor and Principal.

The University of the Free State (UFS) recently (17 January 2024) launched NovaLogix in collaboration with ZZ2, a well-known South African fresh produce company.

This new company, co-owned by the university and ZZ2, aims to develop and produce a probiotic used in the production of fresh produce to enhance plant health and growth. Projects include a focus on improved production techniques, product registration, commercialisation, and improved recipes.

Members of the university’s management structures were present at the formal launch of NovaLogix – which took place on the UFS Bloemfontein Campus – including the Vice-Chancellor and Principal, Prof Francis Petersen; the Deputy Vice-Chancellor: Research and Internationalisation, Prof Vasu Reddy; and the Senior Director of the Directorate Research Development, Dr Glen Taylor. The deans of the two faculties that will be mainly involved in this partnership were also present, namely Prof Paul Oberholster, the Dean of the Faculty of Natural and Agricultural Sciences, and Prof Philippe Burger, the Dean of the Faculty of Economic and Management Sciences.

Among the attendees representing ZZ2 were Dr Tommie van Zyl, the Chief Executive Officer of the ZZ2 Group, Piet Prinsloo, Executive Manager at ZZ2, as well as Wiam Haddad, the new CEO of NovaLogix.

Co-creation and more sustainable outcomes

In his welcoming remarks, Prof Petersen stated that this event marks the culmination of a five-year journey that began in 2019 when he, Prof Burger, and Prof Danie Vermeulen, former Dean of the Faculty of Natural and Agricultural Sciences, first visited ZZ2 to initiate closer collaboration and cooperation.

He is of the opinion that the relationship with ZZ2 is ideally suited to assist the university in realising the core values of Vision 130, the university’s strategic intent to reposition the institution as one of the leading universities in South Africa by 2034.

The knowledge, experience, and expertise that ZZ2 brings to the partnership, complement the exciting and impactful research done by the university’s academics across a range of disciplines. - Prof Francis Petersen

Prof Petersen said that the UFS values partnerships with the private sector, and he considers ZZ2 to be a knowledge partner with co-creation as a key component in this collaboration.

“Working together on a challenge makes the solution more sustainable. I believe that innovation and this co-creation approach will generate outcomes that transform the agricultural sector and impart knowledge to the next generation,” he stated.

“The knowledge, experience, and expertise that ZZ2 brings to the partnership complement the exciting and impactful research conducted by the university’s academics across a range of disciplines. I am looking forward to a partnership that will grow from strength to strength,” concluded Prof Petersen.

Breakthrough developments in the pipeline

According to Dr Van Zyl, ZZ2 would like to continue building a future with the university based on a symbiotic relationship. “We want to ensure that our strengths as an organisation are put to good use,” he said, expressing a strong conviction that there will be breakthrough developments with this initiative.

This work will align with ZZ2’s ‘Work with nature’ journey that began more than two decades ago, steering away from conventional, industrial agriculture towards a system that aims to farm in harmony with nature. “It is important that we nurture nature while using her resources,” he said.

He is excited to work with the university, exploring improved techniques and technologies to find more effective ways towards a sustainable future. “Knowledge partners are important in this journey,” he stated.

Building on existing collaborations

In September 2022, the university entered into a collaboration agreement with ZZ2. The partnership between the two entities included the establishment of FreeFarm Innovation, a company that in turn has a holding in NovaLogix and is designed to leverage the strengths, capabilities, skills, and resources of both parties. Part of the operations of FreeFarm Innovation included opportunities for research, commercialisation, and the enhancement of agricultural products. This has come into effect in projects on, for example, business operations, agricultural sustainability, and innovative approaches to growing fruit and vegetables, to name but a few.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
