Renata van Reenen
Renata van Reenen has been a South African Sign Language (SASL) champion since primary school, and she is using her postgraduate degree to further SASL in higher education.

Renata van Reenen, a master’s student at the University of the Free State (UFS), recalls how a school talk in 1998 by Deaf activist Johan Gouws instilled in her a kind of ‘duty’ to become a champion for Deaf people. Van Reenen, who in 1987 became the first Deaf child in South Africa to receive a cochlear implant, says it was at this talk that she realised that, as a Deaf person, she has her own language, identity, and culture – and that she is not “a person with a disability”. 

Van Reenen is currently a language facilitator in the UFS Department of South African Sign Language (SASL) and Deaf Studies, and she believes that Deaf students should be empowered to embrace their attributes. Her interests include exploring different sign languages around the world, Deaf issues, and how Deaf children are supported in schools for the Deaf. “One of my hobbies is to put my creative ideas on paper, and I would like to develop and record these stories in SASL so they can be accessible to Deaf schools as resource materials,” she says. “These materials would then also be accessible when teaching the subject South African Sign Language as a Home Language.”

Van Reenen, who worked as an assistant teacher at a school for the Deaf for seven years, is passionate about SASL and the lived experiences of the Deaf. We asked her to share some views on empowering the Deaf and SASL: 

Why is it important to empower Deaf students?

When I was 17, I had no Deaf identity. I did not understand sign language and how it was used – when the Deaf person gave a speech at the school, it changed my life. I realised that I am a Deaf person with my own language, identity, and culture, and that I am not a person with a disability. I strongly believe that Deaf students need to be empowered to fully embrace their identity, language, and culture, and through this expectance show the world who we are. My favourite motto I always share with my Deaf learners is: “Believe in yourself, show them what you can do.” I also encourage them to continuously teach Hearing students the beautiful language, as the famous Deaf quote states: “Sign language is the noblest gift God has given to Deaf people.” George Veditz, the former president of the National Association of the Deaf of the United States, said, “As long as we have Deaf people on Earth, we will have signs.” He protected our language at a time (the early 20th century) when the world strongly believed that Deaf people had to learn through oralism and had to learn spoken language in order to function as a “normal person” alongside hearing people.

As a Deaf person, do you believe the UFS community is doing enough to accommodate you, and how do you feel about being part of the Department of SASL and Deaf Studies? 

When I received a link for a workshop I had to attend, I was so overwhelmed when I saw the interpreter on the video link, and knew that it would be extremely helpful for me during my research. The UFS Centre for Universal Access and Disability Support made sure I have full access to any workshops the university provides. It is amazing that my supervisor can also sign. That made me feel at home, being in a Deaf world without communication barriers. The department is an amazing team that supports and encourages me during my studies.

What will you be doing in honour of Deaf Awareness Month?

The SASL Department and I, along with Deaf Studies, have organised a “Signing Space” event in September to bring Deaf and Hearing students together to socialise with each other. This event will give Hearing students the opportunity to learn about the Deaf world. During this event I will give a small presentation such as “Poetry in SASL” that will show that Deaf people have their own literature, and that it forms part of their language, SASL. We will not only focus on presentations but also on fun activities, such as games that are prominent within the Deaf community. 

Why did you decide to pursue your MA at the UFS? 

During the coronavirus pandemic I applied to the University of Gallaudet in Washington, DC to study for a Master of Education in Sign Language degree. Gallaudet is the world's only university in which all programmes and services are specifically designed to accommodate deaf and hard of hearing students. I was accepted to study further and to ultimately become a teacher or lecturer. My aim was to train Deaf adults to qualify in different areas of SASL, ranging from SASL Linguistics, SASL Pedagogy, SASL Media Production, and so forth. In an ideal world these could be offered as short courses through some tertiary institutions which already offer SASL on undergraduate and postgraduate levels. Unfortunately, I did not have enough support, but I did not let it stop my dream. I decided to change my university of choice and applied at the University of the Free State. I am pursuing my MA degree and continuing my studies as a Deaf person. The University of the Free State is providing and recognising SASL. This is a positive step, as South African Sign Language will soon be the twelfth official language of South Africa.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
