Thousand plus hours dedicated to eliminate ‘trash blindness’

03 July 2019 | Story Leonie Bolleurs

KovsiesCare - Clean Up Read More — Tsietsi Ngobese, through the Wesolve4x Cleaning My Planet Campaign, motivated citizens to collectively fill over 23 000 refuse bags to date.

The mission: To collectively fill 20 million refuse bags every Saturday with the help of 20 million people who are cleaning their own communities and our planet for an hour. The message: My planet, my responsibility.

The mission and message that the Wesolve4x Cleaning My Planet Campaign wants to convey, is based on a simple premise: Get community members to donate one hour of their time to cleaning duties every Saturday for the next 20 years until 2039. At the same time provide a continuous educational programme about waste management to the general public and to schools in order to empower them to take responsibility.

Address trash blindness

Tsietsi Ngobese, Chief Executive Officer of this initiative and BSc Actuarial Science graduate, says he understands the transformative power of education and the role it plays in transforming diverse communities. Through outreach programmes in our community and schools, we are slowly eliminating generational trash blindness. We also tackle some of the social determinants of health by encouraging healthy living conditions within our communities through good waste management and recycling.

It is important for Tsietsi to add value to society. He believes that the Wesolve4x Generation will transform the world for the better through education and empowering all citizens.

The campaign – officially endorsed by Miss Earth South Africa, Catherine Constantinides – was launched on the UFS Bloemfontein Campus as well as the Abram Hlope Primary School in Katlehong on 4 May 2019.

“We want to promote the benefits of a clean and healthy environment for future generations,” said Tsietsi.

Since their inception, the group has collectively filled over 23 000 refuse bags with the help of active citizens.

Challenge accepted

When former lecturer, Jan Blomerus, once challenged his Actuarial students to protect the environment in order to decrease the mortality rate (from natural disasters because of the effect of climate change), Tsietsi accepted the challenge. “By inspiring excellence and transforming lives, the UFS plays an important role; I started to believe that I can address societal challenges in the communities I am an integral part of,” he said.

When Tsietsi saw trash piling up everywhere and children playing at illegal dumping sites, he became concerned about the health risk to society. He believes the dumping area is contaminating the air and water around the dumping site.

“I had to be part of the solution to start cleaning up, and most importantly, educating myself and others to continuously take responsibility for our own waste and change our thinking about littering. This is a generational issue and needs a generational approach to unlearn all habits of littering,” Tsietsi pointed out.

As part of his vision, Tsietsi plans to reduce the waste taken to landfill sites and to increase that which is taken directly from households to recycling plants. He also wants to encourage people to find creative ways of converting what has previously been wasted into something useful. “This action can encourage individuals to generate an income from waste,” he said.

Take action

Tsietsi invites all members of the Mangaung community to get involved in the project. This is your opportunity to make a difference on Mandela Day. You can;
• provide sponsorship for educational content on effective waste management, economic opportunities, and health issues to the general public and to schools;
• provide refuse bags, plastic gloves or hand-washing soap (used by community members in every clean-up session);
• join in a collective effort to clean your community by meeting at designated schools or any designated community assembly point on a Saturday (contact 011 307 2005 or info@wesolve4x.com for more information).

Carbon dioxide makes for more aromatic decaffeinated coffee

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way.

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night.

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants.

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
