Zola Valashiya
Nearly a decade ago, Zola Valashiya completed his LLB at UFS and is currently working towards his second LLM in Technology and Innovation at the Seattle University School of Law.

Zola Valashiya graduated from the UFS almost ten years ago with an LLB. Since then, amid life’s twists and turns, he obtained an LLM from the University of Washington, secured a job with a successful law firm in the US, and married the love of his life. Currently, Zola is pursuing a second LLM in Technology and Innovation with the Seattle University School of Law.

Following the advice of a dear friend, Zola figured out what drives him and pursued it relentlessly. “This very simple piece of advice taught me the value of my time, and how much power you take back when you prioritise and protect it,” he remarks.

Advancing the greater good

Fast forward nine-plus years since UFS graduation day, Zola works as a strategic adviser at Coopersmith Law + Strategy, a boutique firm in Seattle specialising in health care, global health, gender/racial equality, and climate health.

“The legal work I do involves various tasks, from drafting legal contracts to conducting data analysis, and developing business strategies for deploying new technologies in health systems or addressing climate change. I value this environment because our efforts are focused on advancing the greater good. I have the opportunity to work on projects that I know will benefit individuals, communities, and the planet,” says Zola.

One of the highlights of his career occurred during the pandemic when he played a key role in preserving one of the largest US training programmes for physicians from diverse backgrounds who serve marginalised communities.

He explains, “The pandemic placed a strain on health-care systems worldwide, leading to cost-cutting measures in private hospitals, the termination of community health programmes, and the closure of small clinics in remote areas, in order to recover from the financial losses. However, these programmes and clinics are vital to the communities they serve because the nurses and doctors are often the only health-care providers for miles around. My contributions have helped to ensure the programme’s continuation, and the continued delivery of quality health care to underserved communities.”

Diversifying his skill set

For the future, Zola says he is working towards diversifying his skill set. “The modern-day lawyer needs to know more than just the law. I have learned coding skills, and I am currently focused on expanding my knowledge of artificial intelligence. In so doing, I am equipping myself with the necessary tools and expertise to thrive in this rapidly evolving field, thereby future-proofing my career.

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.
