Opinion article by Angela Vorster, Clinical Psychologist at the School for Clinical Medicine, University of the Free State.
Twenty-three people will die from suicide today in South Africa. Another 460 South Africans will try to end their lives today. They are from different cultural groups, different income groups, attained different levels of education, speak different languages, range in age from childhood through to elderly, have different genders and sexual orientations. These people have very little in common except that their lives all ended due to the final symptom of an illness. People who experience thoughts of ending their lives describe this mental space as feeling grey. Their thoughts tend to keep returning to the futility of being alive, what a burden they are to those around them, how nothing will ever get better and that nobody can help them. They tend to experience feelings of worthlessness, self-hatred, guilt, hopelessness, immense sadness and despair. Their suffering and emotional pain are excruciating. Nothing is enjoyable anymore. There is nothing to look forward to. Everything is difficult, boring, scary or meaningless. Inwardly they are drowning. But very often they smile, do their job and pass their exams, go on dates and vacations, make plans for the weekend and check up on their loved ones. They look happy in their photos. And when someone asks them if they are okay they say yes. Because they don’t feel like they deserve to feel better. They don’t want to be a bother. They might not call a helpline or make an appointment to see a psychologist or go to their GP for anti-depressants. Because they just don’t have the energy. It’s exhausting pretending to be fine all day. The one thought that brings relief is that they can end this pain. And one day they do. And their colleagues, friends and family are left reeling with shock and disbelief. How could this have happened? How could they have missed the signs? What should they have done differently to prevent this? 

The causes are as complex and varied

This is the purpose of World Suicide Prevention Day which takes place internationally each year on 10 September and through which the International Association for Suicide Prevention endeavours to increase awareness of suicidality, as well as to fight the stigma associated with suicide. Wanting to die can occur along with many other symptoms and disorders including, but not limited to, depression, post-traumatic stress disorder, bipolar disorder, psychotic disorders, personality disorders and substance dependence or abuse disorders. The causes are as complex and varied as the manner in which suicidality may present. It is dangerous to regard only certain signs and symptoms as indicative of suicide risk, because we know that suicide can be extremely unpredictable. There is no way to tell if someone is a suicide risk based purely on their behaviour. However there are certain factors which may indicate an increased risk for self-harm. These include, but are not limited to, having previously tried to end their life, having a psychiatric illness, being seriously ill or having chronic pain or the misuse of substances. Experiencing legal, relationship, financial or academic stressors may increase suicide risk, as well as having access to lethal means to end their life along with being unable to access mental health care. 

So what can you do if you think someone may be at risk of self-harm? Say something. Talk to them. Tell them what you are worried about and give them the space to express how they feel without judgment or condemnation. Reach out to their support system and share your concerns with them. Encourage the suicidal person to make contact with a health care professional – this can be a psychologist, GP, psychiatrist, social worker, psychiatric nurse, counsellor or a suicide prevention help line. Other important members of our community who provide a great deal of assistance to suicidal people and their families include religious and spiritual leaders, teachers, support groups and employee assistance programmes. There are actually so many ways and places to receive health care and support; however the most significant barrier to making use of these resources is sustained by the stigma associated with suicide and mental illness. In our culture of toxic positivity where our photos are touched up, our statuses updated and our successes plastered on various social media platforms, the authentic act of acknowledging when we feel defeated, unhappy or like a failure has become a rarity. The more real, honest and vulnerable we can be about our ‘undesirable’ emotions and experiences, the more space we create for those around us to do the same. When we normalise not being okay at all times, we give ourselves and others permission to speak up when we need help. And this is our greatest weapon against suicide – authentic connection.

What suicide is not

We’ve explored what it may feel like to be suicidal, now let’s focus on what suicide is not. Suicide is not a moral failing. It is not because the person was weak or selfish, it is not because their family was dysfunctional or their faith not strong enough. Suicide is the final symptom of mental illness – and every single person is vulnerable to experiencing suicidal thoughts. Each one of us will be affected by suicide during the duration of our lives, either directly or indirectly. This is irrespective of how successful you are, how supportive your family is or how strong your religious convictions are. Dying by suicide is not a shame. It is not a failure. It is no different to a patient dying from any other disease. And just like any other illness there are symptoms we can look out for and treatments and medications that can assist in recovery. 

Please think before you speak about someone who died due to suicide. I guarantee that at least one person in the conversation has suffered the pain of losing someone in this way. But you probably wouldn’t even know, because stigma silences. Stigma disconnects and alienates those who need support the most. Our words have the power to shame and silence, or to empower and encourage connection, which is lifesaving. Treat each conversation as though there may be someone present who is having suicidal thoughts or is working through the loss of someone they love due to suicide. Often we want to reach out and support families affected by suicide, but don’t because we are afraid of offending, or upsetting or because we ourselves are so uncomfortable with mental illness. But all these survivors of suicide need from you is your calm, empathetic, kind presence, a safe space to express difficult and messy emotions. Without being blamed or shunned or shamed. Support suicide survivors as though a terrible illness took the life of their loved-one. Because that is exactly what happened. 

On 10 September this year I encourage you to light a candle and place it in your windowsill around 8pm wherever you are. This is in remembrance of those lost to mental illness and to show your support to those they left behind. In the words of the International Association of Suicide Prevention: “By encouraging understanding, reaching in and sharing experiences, we want to give people the confidence to take action. To prevent suicide requires us to become a beacon of light to those in pain. You can be the light.”

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.
