Insects on the menu
Beetle juice and bug flour; Drs Ismari van der Merwe and Cariena Bothma are researching the possibility of a high-protein diet consisting of insect ingredients.

You’ve just had a tasty milkshake made from grasshopper juice, now for a light snack. Your choice: Salty cricket cookies or a deep-fried ant delight?

One of these days the above delicatessen may just find its way to your local restaurant menu if Drs Ismari van der Merwe, Cariena Bothma, both lecturers in the Department of Consumer Science, and their enthusiastic team of students have their way. Insects as food are rich in protein, often tasty, and having them on a menu is not as far-fetched as you may think. After all, we know what culinary delights mopani worms – and yes – cooked land snails (enjoyed as escargots) have become over the years.

 

Cricket smackerals

 

When Dr Van der Mewe explains the benefits of her team’s vision for a high-protein diet consisting of insect ingredients (cricket flour as an example), one becomes aware that this could be the solution to a myriad of problems. Insects eat much less than our regular menu items such as cows (beef), sheep (lamb chops) or pigs (pork). Insects as an alternative diet will reduce the negative impact that larger animals have on the environment and greenhouse gases. Insects have faster life cycles and it takes less effort and space to breed and feed them.

“Ugh! Ick! Disgusting,” you might think. But picture the taste lab where volunteers are given regular chocolate cookies made with regular flour, and then asked to compare it with cookies made from cricket flour. Dr van der Merwe assures me that most people will be unable to distinguish between them, often even preferring the cricket smackerals.

 

Heathy alternative

 

Insect breakfast cereals, granola, and snack food is a real and viable solution for the developing world where food is scarce, and hunger is a real issue. But is it healthy? Dr Van der Merwe assures me that during the process of ‘bug to flour’, they are addressing the main concern: micro-organisms that might be detrimental to health. Once the insects or processed insect by-products arrive on your plate, it’s a healthy high-protein alternative that might become the next revolutionary diet.

So, stand aside Atkins, beware Banting, and be gone Gluten-free – there is a new diet on its way to the menu. Brace yourself for beetle juice and bug flour: a diet full of proteins, fat, energy, and essential amino acids.

University Estates at the University of the Free State (UFS) were recently awarded for their amazing initiative to install and operate photovoltaic (PV) and greywater systems on all three of its campuses. They were awarded by the Higher Education Facilities Management Association of Southern Africa (HEFMA), an association of facilities managers operating in the higher-education sector in the Southern African region. All universities and universities of technology in the country form part of this association, which promotes excellence in the planning, construction, maintenance, operations, and administration of educational facilities.

Nico van Rensburg, Senior Director of University Estates, says, “I want to thank HEFMA for this amazing award which motivates for much more and also opens up the doors for so many more opportunities.”

Solar and greywater systems installed at various buildings

In December 2016, 26 solar-driven LED street-light poles and a greywater system were installed at the Legae Residence on the South Campus. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.

On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the expected Afromontane Research Centre have freestanding solar solutions mounted on their roofs. These systems are designed to operate independently of the power grid (Eskom) during sunlight hours when the PV solar panels are heated by the sun.

Teamwork equals ground-breaking results

“This was truly a team effort with a variety of role players who contributed,” says Van Rensburg. He believes that higher education can do more to make use of other environmentally sustainable initiatives, and to go beyond just erecting and renovating buildings.

The UFS executive management is also extremely proud of the team that were involved in the project. Prof Nicky Morgan, former Vice-Rector: Operations, says, “It’s been extraordinary what we could achieve at all three campuses with such a small team.” Nadeem Gafieldien, Director: Property Services at Stellenbosch University, showered the UFS with praise. “This is truly ground-breaking for Higher Education (HE) and you are truly leaders in these renewable energy projects in the HE sector.” He says we need to demonstrate to other institutions in the HE sector that this is the future and that it makes the institutions both environmentally and financially sustainable.
