UFS Department of Chemistry to bring relief to many with invention of reusable sanitary pads

A new reusable sanitary pad (RSP) will bring relief to many women during their menstrual cycle.

Dr Marietjie Schutte-Smith, Senior Lecturer in the University of the Free State (UFS) Department of Chemistry, together with Prof Deon Visser, Head of the Department of Chemistry, and Prof Lizette Erasmus, Associate Professor in the same department, are leading a diverse team that decided 18 months ago to do something about the challenge of not having access to conventional sanitary ware and water due to poverty and infrastructure challenges – a challenge many young women in South Africa face every month.

The team included Prof Katinka de Wet, Associate Professor in the Department of Sociology, in this process in an effort to gain a better understanding of the current perceptions, experiences, and preferences of those who will ultimately use these sanitary products.

“We wanted to do research that has a direct and tangible impact on our immediate society,” says Prof Erasmus.

New technology

The research team turned their focus to reusable sanitary pads (RSPs), specifically the invention of a product that can be cleaned without being exposed to direct sunlight.

Dr Schutte-Smith explains that most RSPs must be exposed to direct sunlight to dry and prevent bacterial growth. “Exposing RSPs to sunlight is challenging for users residing in densely populated areas, besides the fact that many people find the public display of sanitary products embarrassing.”

She believes a product that can be washed and left indoors to dry, one that has antibacterial and antimicrobial properties under normal light conditions, and with durable superabsorbent inner layers, could alleviate some of these challenges.

The team then started working on technology including nanoparticles (NPs) that affix to textiles and will kill germs and fungi when exposed to normal light.

Prof Erasmus says, “Attaching NPs to materials is not a new concept, however, the use of nanoparticles that are activated by normal light conditions is new… Also, we have synthesised several absorbent materials using natural fibres and biopolymers as the main constituents. This is an ongoing process to enhance their absorbent properties and durability so that they can be included in our product.”

She adds that when the RSPs are eventually discarded (after four to five years) they will break down in the environment and not contribute further to the plastic waste problem the world is facing. Most disposable sanitary pads (DSPs) are not environmentally friendly and take 500 to 800 years to decompose.

Dr Schutte-Smith goes on to explain that the sanitary ware will be manufactured by sewing different layers together. “The outer lower layer will consist of a hydrophobic (fluid-repellent) layer to prevent leaking, and the inner layer will consist of the synthesised and biodegradable superabsorbent polymer (SAP).”

The product will be mixed into cotton and will be removable (for better cleaning). “It will also contain NPs that use natural indoor light to disinfect. The top layer also contains our nanotechnology and will relay fluids to the absorbent inner layer.”

Social implications

Besides the important work being done by chemists to incorporate technology that will ensure the product makes sense scientifically, it is also important that the experiences, perceptions, and ideas of end users are kept in mind.

Prof De Wet says social scientists were included in the design and development of this product to ensure that the actual needs of the end users are taken into consideration. The idea is to collaborate with school learners and university students to get their feedback on the development and eventual use of these newly developed RSPs.

“The aim, therefore, is to sensitise menstruating individuals as to the possible personal advantages of using reusable sanitary pads, including that it is less expensive in the long run, thus eliminating the problem of access to quality and reliable sanitary ware. There could even be some potential health advantages to using such products, as current disposable products contain phthalates that have been shown to have adverse health effects on individuals,” she states.

Prof De Wet also points out the environmental benefits of using reusable sanitary products, and the importance of sensitising young people to the environmental costs of single-use plastic consumption, of which sanitary ware is a major contributor. “Environmental consciousness is part of the social side of the project, given the pressures globally on the human-induced impact on our planet, and its devastating consequences,” she says. “We want the science (chemistry) to have a real social impact in people’s lives individually, socially, and environmentally.”

Future steps

According to Prof Visser, the team already has a prototype in place, which now needs to be perfected through inputs from end users. They hope to have an industry partner within the next six months that will help to get this product on the market.

The team of chemists worked hard to develop a product that will have the potential to change many lives for the better, allowing young girls and women to thrive in life.

UV vestig hom afgelope eeu as leier op verskeie terreine

2004-05-11

Michelle O'Connor - Volksblad - 11 Mei 2004

Ondank terugslae nou 'n 'gesonde volwassene'

HOEWEL die Universiteit van die Vrystaat (UV) vanjaar sy eeufees vier en met 23 000 studente die grootste universiteit in die sentrale deel van die land is, was dié instelling se geboorte glad nie maklik nie. MICHELÉ O'CONNOR het met prof. Frederick Fourie, rektor, oor die nederige begin van dié instelling gesels.

DIE behoefte aan 'n eie universiteit in die Vrystaat het reeds in 1855, kort ná die stigting van Grey-kollege, kop uitgesteek.

Grey se manne het hulleself teen 1890 begin voorberei om die intermediêre B.A.-eksamens af te lê. Dié eksamen het hulle toegang gegee tot die tweede jaar van 'n B.A.-graad aan die destydse University of the Cape Good Hope, nou die Universiteit van Kaapstad.

"Presidente F.W. Reitz en M.T. Steyn het destyds albei die stigting van 'n universiteit hier bepleit. Die grootste rede was sodat die seuns van die Vrystaat nie weggestuur word nie.

"Dié twee se droom is op 28 Januarie 1904 bewaarheid toe ses studente hulle onder dr. Johannes Bril, as hoof/rektor van Grey-kollege, vir die graad B.A. ingeskryf het. Dié graad is aanvanklik deur die Kaapse universiteit toegeken.

"Net die klassieke tale soos Latyns en Grieks, die moderne tale, Nederlands, Duits en Engels, filosofie, geskiedenis, wiskunde, fisika, chemie, plant- en dierkunde is aanvanklik aangebied.

"Die UV se geboue het gegroei van 'n klein tweevertrek-geboutjie wat nou naby Huis Abraham Fischer staan, en verblyf in die Grey-kollege se seunskoshuis," sê Fourie.

Volgens hom is die universiteit se eerste raad en senaat tussen 1904 en 1920 saamgestel. Die eerste dosente is aangestel en die eerste geboue opgerig. "Dié tyd was egter baie moeilik.

"Die instelling het teen 1920 net 100 studente gehad en was geldelik in die knyp. Daar was geen vaste rektor nie en geen vooruitgang nie. Vrystaatse kinders is steeds na ander universiteite gestuur.

"Ds. J.D. Kestell, rektor van 1920 tot 1927, het egter dié instelling finaal gevestig.

"Hy het self studente van oor die hele Vrystaat gewerf en geld by onder meer kerke en banke ingesamel. Kestell het selfs Engelse ouers oortuig om hul kinders na die Greyuniversiteitskollege (GUK) te stuur en teen 1927 het dié instelling met 400 studente gespog.

"In die tydperk tussen 1927 en 1950 het die GUK weer verskeie terugslae beleef.

"In dié tyd was dit onder meer die Groot Depressie en die Tweede Wêreldoorlog. Die armblanke-vraagstuk het regstreeks op studente en dosente ingewerk en die politieke onderstrominge van dié tyd het die instelling ontwrig.

"Die GUK het egter oorleef en die Universiteitskollege van die Oranje-Vrystaat (UKOVS) is in 1935 gebore," sê Fourie.

Hy sê in dié tyd is verskeie fakulteite gevestig en teen 1950 het die UKOVS met 1 000 studente gespog.

Teen 1950 het dit 'n onafhanklike universiteit geword en die naam is verander na die Universiteit van die OranjeVrystaat (UOVS).

Dié tydperk is gekenmerk deur Afrikaner- en blanke selfvertroue en heerskappy. Studentegetalle het tot 7 000 in 1975 gegroei en heelwat vooruitgang het in dié tyd plaasgevind.

"Tussen 1976 en 1989 sukkel dieuniversiteit weer met onder meer ekonomiese krisisse, die land se politieke onstabiliteit en word die UOVS geï soleer.

"Een ligpunt in dié tyd is die toelating van die eerste swart studente, die nuwe Sasol-biblioteek en die fakulteit teologie wat die lig sien.

"Tussen 1990 en vanjaar het die UOVS verskeie op- en afdraandes beleef. Die universiteit doen nie net die eerste stappe van transformasie nie, maar begin ook aan 'n beleid van multikulturaliteit werk.

"Die UOVS se naam verander in 1996 na die Universiteit van die Vrystaat/University of the Free State en in 2001 word die Sotho-vertaling bygevoeg.

"Geldelike druk en probleme neem drasties toe en personeel word gerasionaliseer.

"Teen 2000 begin die UV met 'n draaistrategie en studentegetalle neem tot meer as 23 000 toe," sê Fourie.

Hy sê die UV het die afgelope eeu nie net verskeie terugslae oorleef nie, maar homself ook op verskeie gebiede as 'n leier gevestig.

Die universiteit behaal sy eie geldelike mikpunte, neem 'n nuwe taalbeleid van veeltaligheid aan en herbelê in personeel.

Die instelling inkorporeer die kampusse van die Vista- en Qwaqwa-universiteit en groei internasionaal.

Die UV vestig ook fondamente van 'n institusionele kultuur van verdraagsaamheid, geregtigheid en diversiteit.

"Die baba het in die afgelope eeu 'n gesonde volwassene geword."
