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.

“Breakthroughs depend on people believing in their own ideas”

2015-07-23

TED is a renowned international non-profit organisation dedicated to disseminating “ideas worth spreading” in the form compelling talks lasting up to 18 minutes.

Lerothodi Molete’s vision is to witness the youth of Bloemfontein emerge at the forefront of technological, scientific, and entrepreneurial innovations in both South Africa and the global arena.

Molete and Bonginkosi Leeuw are the organisers of TEDxUFS. Their duty is centered on inspiring people to believe in, and express, their ideas. These University of the Free State students have taken it upon themselves to inspire the youth to “push the boundaries of society.”

The second TEDxUFS event to be hosted by the university presents a unique opportunity for students, staff members, and the general public to mingle with influential speakers from across various disciplines.

Details of the event:

Date: Saturday 1 August 2015

Time: 08:00- 18:00

Venue: Albert Wessels Auditorium, Bloemfontein Campus

The keynote speakers include: Mmusi Maimane (Federal Leader: Democratic Alliance), Gareth Cliff (Radio personality: Cliff Central), Pieter Geldenhuys (Futurist), Brian Kally (Director: Arrow Logistics), Jonathan Jansen (Vice-Chancellor and Rector: UFS), Ricardo Peach (Director: Vrystaat Arts Festival, Pamela Nomvete (Former actor and writer), Gil Oved (Founder: Creative Counsel), Pepe Marais (CEO: Joe Public), Angelo Mockie (Senior Officer: Student Affairs and musician), Philippa Tumubweinee (Senior Lecturer in Architecture: UFS), and Melody Mentz (Psychology Senior Professor: UFS).

The reason behind the #AskWhy theme

"Why is a small word but it’s a quick, broad, sharp and abrupt one,” explains Leeuw. “It is the chosen word of the non-conformist, the defiant, and the visionary. It is a confrontational word. It challenges what is thought to be impossible.”

The ability to interrogate reality is what society and economies are built on. The absence of the fear to question encourages the capacity to progress.

Motivating young people to follow their dreams is the reason why the TEDxUFS team is persistent in their endeavours. Molete believes that, in order to change anything, people need to ask why.

Background of the innovation powerhouse called TED(x)

TED is a renowned international non-profit organisation dedicated to disseminating “ideas worth spreading” in the form compelling talks lasting up to 18 minutes.

In 1984, it was introduced as a conference exploring Technology, Entertainment, and Design. Three decades later, TED covers a wide variety of topics of global significance, reflecting the contemporary era in more than 100 languages.

TEDx events are under the TED umbrella. These events are organised independently, and create a platform for deliberating on local matters. The programme assists communities, organisations, and individuals to stimulate critical dialogue.

On 25 July 2014, the UFS hosted its inaugural TEDxUFS conference at the Odeion theatre on the Bloemfontein Campus, where eleven speakers addressed an audience of 150 people on interdisciplinary topics ranging from economics to entrepreneurship, technology, art, design, and theology.

This year, 200 seats will be available for innovative revolutionary individuals in search of inspiration.

Tickets are available at 0619284253 / 079 381 4126. Prices: R80 (Student/scholars) and R350 (Public/staff)
