reusable sanitary pads
A team of researchers from the UFS is part of a project to invent a reusable sanitary pad that is safe, hygienic, comfortable, easy to use, and friendly to the environment. From left are: Prof Katinka de Wet, Dr Marietjie Schutte-Smith, Prof Deon Visser, and Prof Lizette Erasmus.

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.

UFS plans to improve undergraduate pass rate
2005-01-13

The University of the Free State (UFS) will introduce a new foundation programme this year 2005 in an effort to improve the academic performance of undergraduate students.

According to Mr Francois Marais, Head: Centre for Higher Education Studies and Development (CHESD) at the UFS, the programme will assist students by providing for the development of cognitive and critical thinking skills by means of the integration of appropriate thinking skills (such as creative thinking, decision-making, problem solving, reasoning, and how to learn), into the subject content of university courses.

“The foundation programme will benefit students from disadvantaged school backgrounds and, in future, those whose performance in proficiency tests points to the need for additional development in, for example, language proficiency, mathematical literacy, computer skills and life skills,” says Mr Marais.

Based on their level of achievement in the final Grade 12 examination (Senior Certificate), students will be referred to the foundation programme.

In order to improve students writing and reading abilities for higher education studies, foundation programme students will be offered academic language courses in English and Afrikaans.

Kovsie Counselling will render appropriate services, eg career guidance and support to these students.

The new foundation programme will be implemented in the faculties of Natural and Agricultural Sciences, Economic and Management Science, the Humanities and Law.

The duration for this programme differs from faculty to faculty. In the Faculty of Law it will take five years, while in the faculties of the Humanities, Natural and Agricultural Sciences, and Economic and Management Sciences it will take four years.

The national Department of Education will fund the foundation programme for three years. Funding for such programmes was made available to all higher education institutions in South Africa.

The welcoming function for all new first-year students and their parents will take place on Saturday 15 January 2005 at 11:00 in the Callie Human Centre on the main campus in Bloemfontein.

The registration of first-time entering first-year students who applied before 30 November 2004 to study at the Bloemfontein campus will take place from Monday 17 January 2005 to 21 January 2005 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 to 29 January 2005.

Postgraduate students, first time entering first year students and other students who applied for admission to the main campus after 30 November 2004 must register at the Callie Human from 31 January 2005 to 4 February 2005.

Due to the limitations placed by government on student numbers, the applications of students who applied late will be regarded as pending and will be processed as places become available.
