Michelle de Lange
Michelle de Lange was placed fourth in the world in the Chartered Global Management Accountant exams.
A letter from the Vice-President of Examinations at the Association for International Certified Professional Accountants, Stephen Flatman, reads: “The Chartered Global Management Accountant (CGMA) Examination Board has determined the highest achievers at this level and I am pleased to inform you that you have obtained fourth position in the world for the May 2019 Chartered Institute of Management Accountants (CIMA) Gateway Exam.” The letter was addressed to Michelle de Lange, lecturer at the University of the Free State’s (UFS) School of Accountancy.

This achievement in the tough Chartered Institute of Management Accountants (CIMA) examination is a step in the right direction for De Lange who has been tasked with assisting in coordinating and presenting a new Financial Management qualification next year. “I want to be somewhere where I can make a difference, change a life, plant a dream in someone’s heart and help guide our future generations,” says De Lange. 

Taking local and global footsteps

Prof Frans Prinsloo, Director at the UFS School of Accountancy, has only praise for De Lange and says he looks forward to her influencing the climate and culture of academics. “It is noteworthy that we will be offering the BCom Honours in Financial Management in 2020 and all course content will be aligned to the CIMA Management Level outcomes in order to prepare students to write this exam next November. De Lange will be one of the lecturers on this programme,” Prof Prinsloo says. 

For the love of Accounting

“When I eventually qualified and started working as a financial manager of a large company in Bloemfontein, I realised just how much I loved the field of management accounting – blending leadership, cost and management accounting and strategic decision-making,” says De Lange. 
Although her passion for the field of accounting can be traced back to high school, it was the corporate world that re-ignited the strong spark. This passion has undoubtedly contributed to her international acclaim.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
