Dr Jana Vermaas and Ketshepileone Matlhoko are working on research that leaves your washing clean and fresh without the use of any detergents, which is also beneficial to the environment.

Cold water or hot water? Omo or Skip? Laundry blues is a reality in most households and when you add stains to the equation, then what was supposed to be part of your weekly household routine, becomes frustrating and time consuming. 

Researchers at the University of the Free State (UFS) are conducting research that is putting a whole new environmentally friendly spin on laundry day.

Sustainability and environmental conservation

Dr Jana Vermaas, Lecturer in the Department of Sustainable Food Systems and Development at the UFS, is passionate about textiles and sustainability – almost a decade ago, she conducted a study on the efficacy of anolyte as a disinfectant for textiles.

She describes the process: “During electrochemical activation, a dilute solution of natrium chloride/salt passes through a cylindrical electrolytic cell where the anodic and cathodic chambers are separated. Two separate streams of electrochemically activated water are produced. Anolyte as water was produced at the positive electrode and has a low pH, high oxidation-reduction potential and contains dissolved chloride, oxygen, and hydroxyl radical. It also has an antimicrobial effect.”

The benefits of this process are in line with her enthusiasm for environmental conservation. 

According to Dr Vermaas, the amount of water and chemicals used to clean textile articles is massive. “Chemicals used to disinfect, for example, hospital laundry, are hazardous. Not all laundries in the industry have a closed loop system or try to remove the chemicals before the wastewater is discarded.”

“Different amounts of detergents have various effects on our fauna and flora. Due to their low biodegradability, toxicity, and high absorbance of particles, detergents can reduce the natural water quality, cause pH changes in soil and water, lead to eutrophication (too many nutrients), reduce light transmission, and increase salinity in water sources.”

“But with the catholyte and anolyte process, water returns to its original status, which means that the water solution becomes inactive again after production where it existed in a metastable state while containing many free radicals and a variety of molecules for 48 hours. Thus, no chemicals are left in the wastewater. The water can therefore be recycled, not as potable water but, for example, to flush toilets or to water plants.

“We should do what we can to save water,” she says. 

Should you, like Dr Vermaas, also feel strongly about protecting the environment and want to obtain one of these machines that leaves your washing clean and fresh without the use of any detergents, you will be able to find such an appliance in South Arica. However, it does not come cheap. “It is a bit costly for residential use, but might be more accessible in the future,” states Dr Vermaas, who is of the opinion that it is a more sustainable option for commercial laundries.

Detergency properties and colourfastness 

Recently, more research has been conducted on this topic, but with a focus on the detergency properties of the catholyte to clean different textile fibres (natural and synthetic). Catholyte, she explains, is water produced at the negative electrode with a high pH, low oxidation-reduction potential, containing alkaline minerals. It also has surface active agents that increase the wetting properties, and it is an antioxidant. 

“A master’s student in the department, Ketshepileone Matlhoko, will be submitting her dissertation at the end of November on the possibility of using the catholyte as a scouring agent to clean raw wool,” says Dr Vermaas. 

The department is also conducting studies to investigate the influence of both catholyte and anolyte on colourfastness.

Official opening ceremony of the UFS Qwaqwa Campus
2006-02-15

Official opening ceremony of the UFS Qwaqwa Campus
11th February 2006 – Multipurpose Hall

Opening Speech:
Prof. Peter A. Mbati
Campus Principal

Successfully rising to the challenges of incorporations and mergers – developing a vibrant and academically stimulating satellite campus of the University of the Free State.

Thank you Mr. Program Director and good morning ladies and gentlemen.

I wish to once again welcome all of you to the official opening ceremony of the University of the Free State QQ campus.  Thank you for taking time to share with us an important date in our campus academic calendar.  I bring you greetings from our Rector and Vice Chancellor Prof. Frederick Fourie.

During such occasions we try and reflect on important matters that have affected us as an institution in the preceding year, commit ourselves to specific objectives for the current year, while planning for the proceeding year.

Today I shall be talking on Successfully rising to the challenges of incorporations and mergers – developing a vibrant and academically stimulating satellite campus of the University of the Free State’.

SRC inauguration
I would like to congratulate the SRC President and the entire SRC leadership for being elected into important positions of student leadership and authority. 

As a university we are proud of the quality of our student leadership on the Qwaqwa campus.  I am confident that you young leaders will rise to the challenges of your office and discharge your duties with diligence and without fear or favour.  That you will rise above your party affiliations and provide effective leadership to the entire student body on campus.
                              
Leadership is complex and requires you to be objective, just and fair in your approach to the many challenges that you will encounter.  You will be judged not by the populist decision that you take when confronted with difficult choices, but rather, on the wisdom that you exercise in reaching consensus in decision making processes.

The era when management and student leadership viewed each other with suspicion and as adversaries is long gone.  Management, academic and administrative staff, parents and students must have common agendas in as far the  quality growth and development of our university is concerned and to strive towards academic excellence.  I leave the challenge to you students, and more so to the inaugurated student leaders to define your agenda in achieving this noble objective.  I trust that you will make the right choices.

Brief history of incorporation
On the recommendations of the National Working Group of Higher Education, the Qwaqwa Campus of the then University of the North was incorporated into the University of the Free State on 1st January 2003.  We suddenly had to move from a campus that was originally semi-autonomous and with its own culture developed over almost 20 years, into a campus that had to operate as a fully integrated campus of the UFS, a 100 year old institution with its distinct culture.

Following incorporation, we not only had to continue with our core business of teaching, learning, research and community service, but we also had to engage in other important aspects such as exploring the most appropriate models of governance for the campus, encouraging dialogue and interactions at all levels between personnel at the different campuses with a view to developing trust between colleagues. And with the added dimensions such as participation in the transformation task team we in effect are at the fore front of developing a new institutional culture at the UFS and a truly South African University.

UFS Strategic objectives
The strategic and transformation priorities of the University of the Free State for 2006 – 2008 as approved by the Executive Management at its retreat in January 2006 are:

  • Quality and Excellence
  • Equity, diversity and redress
  • Financial sustainability
  • Regional co-operation and engagement

Central to this priority is the integration of the Qwaqwa campus as a valuable constituent part of the UFS, and the strategic reconfiguration of the campus in order that the UFS can play a meaningful role in regional engagement and development.

  • National leadership

The five strategic objectives cannot be viewed in isolation and run simultaneously and in concert with each other. 

The Question must therefore be what we on the QQ campus, staff and students, parents and our broader community are willing to do to achieve these strategic objectives. The reconfiguration and strategic planning of this campus, and therefore its success, must be a collaborative effort between colleagues at QQ and on the main campus.  We must all be ready to work together, to plan together, to shoulder responsibilities together and sometimes, to share the pain and disappointments together. 

The second question must therefore be: are we prepared to go that extra mile for our campus to ensure that we claim our rightful stake within the ranks of well respected academic institutions of higher learning in this country?  At this point in its history this campus requires committed men and women from across the cultural spectrum who appreciate the challenges ahead of us and who are ready to give of their best and to constructively engage at all levels to make this dream a reality.  Because this dream is possible and this dream will be realized!

Quality and Excellence (1st strategic objective)

As mentioned by the Rector in his speech at the official opening ceremony of the university on the main campus on Friday 3rd February, the university will in 2006 pay extra attention to Quality and Excellence.  This is informed by the Higher Education Quality Committee’s (HEQC) institutional audit which is scheduled to take place this year.  Our university as well as several other HEI’s will be subjected to this audit.  This will call for a lot of hard work on your part in preparation for a successful audit and in this regard therefore I request for your cooperation.

As a further step in confirming our commitment to quality and excellence, we have simultaneously introduced on the QQ campus and the main campus workshops on performance management systems to a cohort group.  This will be expanded in 2006 to a wider group of managers on the QQ campus to include among others all Program Heads and Subject Heads. PMS is an invaluable tool for fair, effective and efficient management of a very important resource on campus – the human resource.  Benefits of PMS include among others:

  • Instilling and enriching a culture of performance management (quality assurance) as an integral part of the day to day functioning of staff at the campus
  • Improving staff performance through mentoring, development and training

Tri campus project
One of the more important projects that we as a university undertook in 2005 was the Tri Campus Project which was coordinated by the Free State Higher Education Consortium (FSHEC) through Niel Butcher and Associates consultants.

The Tri-Campus project focused on the strategic planning for higher education campuses in the Free State that have been incorporated with UFS and CUT during the reshaping of the South African higher education landscape. The Bloemfontein Vista campus and the Qwaqwa campus of the University of the North were incorporated with the UFS, and the Welkom Vista campus with the CUT.

The planning process involved a range of research and consultation activities during the course of 2005. This included:

  • Conducting situational analyses of the Qwaqwa campus during which staff and students were widely consulted;
  • Consulting with the campus and with a range of stakeholders in the sub-region
  • Review of the Free State Provincial Growth and Development Strategy and Integrated Development Plans (IDPs) of the regions and other research of relevance to the sub-regions, province and country.

An operational framework for the reconfiguration of the campus with a range of possible Program Qualification Mixes has been produced.  In December 2005, the Rector, the Vice Rector Academic Planning Prof. Magda Fourie and I discussed this document with senior members of the DoE in Pretoria, and we will soon be meeting with the National Minister of Education Me Naledi Pandor for her guidance and to seek support in the further refinement of the document and subsequent implementation.

Recapitalization
This year a further R 6 M has been budgeted for recapitalization.  In about two weeks time the third of phase of renovations on campus will commence and attention will be given to the administration building, the humanities and the outstanding work in the lecture hall complex.  There- after the library, sciences and education buildings will follow.  As you will recall a substantial portion of the R 8.4 million in 2005 was used to upgrade the student residences and the lecture hall complex.

I am certain that the renovations and upgrading of our infrastructure and physical facilities including landscaping will create an enabling environment for you to enjoy your work and studies on this campus.

Renovations come with some measure of inconveniences and I therefore wish to request for your patience and support during this period.

Closing remarks
There is a heightened spirit of optimism on what the future holds for this campus.  This is evident when I talk to a large cross section of staff and students of this campus – and I therefore invite all of you to come and be partners with us on this journey of optimism and hope of what the future holds for the UFS – QQ campus.

Thank you and God bless!
