The success of the Eco-Vehicle Programme and future steps

Eco Vehicle Race 2024 — This year's Eco-Vehicle Skills Programme saw remarkable participation. A total of 148 students completed the programme successfully.

For the past seven years, the University of the Free State’s (UFS) Kovsie ACT has proudly hosted the successful Eco-Vehicle Race. This event has grown into a major highlight, thanks to the significant support from MerSETA (Manufacturing, Engineering and Related Services), which has enabled the development of a comprehensive skills programme focused on sustainable energy and eco-vehicle technology.

In 2020, MerSETA's funding allowed Kovsie ACT to create a detailed skills initiative culminating in the exciting 2021 eco-vehicle race. Over nine months, 150 students received extensive training in eco-vehicle technology. This programme provided students with both theoretical knowledge and practical experience, preparing them not only for the competition but also for real-world applications of sustainable energy solutions.

Dr WP Wahl, Director of Student Life, emphasises the value of this initiative, saying, “This effort provides students with a set of skills that will help position them in the labour market. They are equipped with basic knowledge and abilities in sustainable energy, enabling them not only to compete in the eco-vehicle race but also to comprehend the inner workings of the vehicle.”

CUT Team 4: Overall winner of Kovsie ACT’s Eco-Vehicle Race 2024

According to Teddy Sibiya from the Kovsie ACT office, this year's Eco-Vehicle Skills Programme saw remarkable participation and achievements. A total of 148 students - 118 from the UFS and 30 from the Central University of Technology (CUT) - completed the programme successfully. Additionally, 10 engineering mediators completed the Mediated Learning Experience course, providing mentorship essential to the students.

In the 2024 Kovsie ACT Eco-Vehicle Race, CUT Team 4 emerged as the overall winner. Kovsie Q secured second place and East College took third place. North College won the Spirit Cup and was announced as the pitstop winner alongside East College.

In the Obstacle Race, which tested teams' control over their cars through various challenges, CUT Team 4 claimed the winning title. They also came in first place in the Endurance Race, where the objective was to complete as many laps as possible using the least amount of energy in 45 minutes.

The race took place at the UFS’s Bloemfontein Campus on Akademie Avenue, next to the George du Toit Administration Building, with spectators watching from the Red Square parking area.

Eco-Vehicle Sustainable Skills Programme 2.0 introduced

Sibiya announced the next phase of the journey - the Eco-Vehicle Sustainable Skills Programme 2.0. “With continued support from MerSETA, we have expanded our partnerships to include Nelson Mandela University and will continue to involve students from the Central University of Technology.”

“In the next phase, the focus is on developing a new eco-vehicle prototype and creating an advanced skills programme around it,” adds Sibiya. “We aim to debut and race this new eco-vehicle by 2025, continuing our commitment to innovation and sustainable energy education.”

Dr Wahl elaborates, “Students will be taught the same skills, but the learning experience will be deepened. The skills programme consists of five cycles. In cycle one, the students build a race car on a small scale that includes a charging station and a small solar panel. In cycle two, students learn to programme the small-scale racing car from their cell phones or laptops. In cycles three and four, they build the larger race cars with battery packs and solar panels. All of these come together in cycle five during the Eco-Vehicle race when the energy conservation of the cars is tested.

Support from sponsors

Several sponsors were involved in this year’s Eco-Vehicle Race. OFS Fire supported the race with equipment and certified training for all the participating students. Several of the teams also secured sponsorships: East College from Deluxe Grills, South Campus from SA Truck Bodies, West College from Mpeki Tsh Trading and Project, and the CUT Teams from the South African Institute of Electrical Engineers (SAIEE). Haval also exhibited a car at the event.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.

What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
