GCX Africa logo We are experiencing one of the biggest innovation waves of our time. The last major innovation wave was really characterized by technology i.e. IT, internet and biotechnology. During each transition to a new innovation there has been a paradigm shift. Businesses have had to change  the manner in which they did business otherwise they risked failure.

Kodak is probably the poster child of the collateral damage that happened in the last technology wave, whereby, they didn’t transform fast enough, they weren’t innovative enough and they just literally never made it with small garage-type operations eclipsing them and becoming the leaders of industry in that space.

Now today, the current innovation wave is characterized by things like renewable energy, radical resource productivity, carbon neutrality, zero waste. These concepts  have been borne out of necessity leading from the damage that has been done over the past decades since the industrial revolution. This age has been termed the ‘Green-ICT’ age.

When GCX Africa started in 2007, with our former name as Global Carbon Exchange, our tag line was “Grow and be Green”.  Over the years  this  has evolved from “Making Business Sense of Climate Change” then to “Measured Sustainability” and finally “Making Business Better”. During this last rebranding, we got rid of the carbon in our name because we realized, that this is not about sustainability nor is it about responding to climate change. What we were doing with our clients was actually driving efficiencies, getting zero waste, renewable free energy, sharing value across the entire value chain, creating more profits, more value in business, creating long-term shareholder returns. We were just actually making business better.

When people ask, “what do you mean you make business better?” Our response has been, we make Business Better for the benefit of the shareholder. What we do at GCX Africa is, we position companies on that innovation wave to make sure that they have the visibility and the ability to manage their risks effectively, but more importantly, to be able to capitalize on what is the biggest opportunity of our lives.

IPW Integrated Production of Wine (IPW) is a voluntary environmental sustainability scheme established by the South African wine industry in 1998. The 2000 vintage was the first to be certified under this scheme. Certification of IPW compliance falls under the jurisdiction of the Wine and Spirit Board (WSB), with a dedicated IPW office responsible for administering the scheme since its promulgation in 1998.


The CSIR is one of the leading scientific and technology research, development and implementation organisations in Africa. Constituted by an Act of Parliament in 1945 as a science council, the CSIR undertakes directed and multidisciplinary research, technological innovation as well as industrial and scientific development to improve the quality of life of the country’s people.

The WRC was established in terms of the Water Research Act (Act No 34 of 1971), following a period of serious water shortage. It was deemed to be of national importance to generate new knowledge and to promote the country’s water research purposefully, owing to the view held that water would be one of South Africa’s most limiting factors in the 21st century. In 1971 when the WRC was founded, water research and development (R&D) in South Africa was limited to a few institutions and the funding level inadequate.

Biolytix logo

    Biolytix is a household wastewater treatment system, which converts waste into a re-usable resource in the garden. Not only is this a waste of precious resources, but also most municipal sewage treatment facilities in South Africa cannot keep pace with existing residential and commercial demand. This failure results in a poor quality of wastewater being released back into the natural system from these facilities. Treating wastewater at the source of its creation and converting it into a reusable resource for watering the garden is the ideal way to conserve water and minimise the strain household consumption places on municipal treatment facilities.  

Winelands UV

Winelands UV Technology is based in Stellenbosch and is dedicated to bring the latest UV technology to South Africa. The UV market has been growing considerably over the last few decades because of the development of efficient UV systems suitable for high flowrates and water with a low UV transmission. This has caused UV to become the first choice for disinfection for drinking and waste water in Europe and the USA.

The South African market is fast realising the value of UV treatment as an affective, environmentally friendly and sustainable alternative to Chlorination and the use of other Chemicals.

In some situations UV is used in conjunction with low dose Chlorination to sterilize the water for Cryptosporidium and Giardia, which are not effected by Chlorine.

PRS, originally started in 1996, undertook many studies focusing on the aerobic and anaerobic remediation of water, air and soil contamination. Most of these projects involved a major proportion of site specific investigation and research and ranged from paper mill effluent bio-degradation, waste classification and delisting, EIA specialist investigations to wetlands design. One major project involved the relative effectiveness of treatment of a highly complex mine water with permeable reactive barrier(PRB) technology.
