Moving towards a more circular economy – which is based on the principle of using, recycling, and reusing in an (almost) closed loop – could deliver opportunities including reduced pressures on the environment; enhanced security of supply of raw materials; increased competitiveness; innovation; growth; and jobs. However, the shift also poses challenges such as financing; skills; consumer behaviour and business models; and multi-level governance.
Bubele Nyiba, the CEO of the ROSE Foundation (Recycling Oil Saves the Environment) says that the used oil industry in South Africa is an example of a sector that would greatly benefit from becoming an entirely closed circular economy through re-refining, but this will take time.
“Internationally, there is a significant trend towards re-refining of used oil back to base oil and it is thought that 70% to 80% of used oil will be re-refined back into base oils in Europe by the end of 2020.”
Environmentally, re-refining used oil is the ultimate solution for several reasons:
- Less utilisation of natural resources;
- Emissions of carcinogenic compounds through re-refining are 15 times lower;
- CO2 emissions from re-refining are two times lower; and
- Re-refining offers an effective conservation of synthetic base oil compounds.
“Coupled with the obvious environmental benefits of re-refining, there are economic benefits to creating a closed loop economy – South Africa has an over-reliance on base-oil imports, which can carry long lead times and are impacted by exchange rates, logistics, weather patterns, port operations etc. All of which make re-refining an appealing choice for us,” says Nyiba.
However, South Africa will struggle to transition towards a closed loop model. “The local market is driven on price and it is very expensive to set up a plant to produce high quality re-refined base oil. Installing the re-refining infrastructure runs into millions and very few businesses can afford an outlay of this magnitude. Coupled with this, we have a very high demand for burner fuels in South Africa – out of 350 million litres of new oil sold per annum, 120 million litres is collected for recycling; 90% of this is processed into fuel oil, to be used in furnaces, boilers, and other industrial heating requirements.”
There are also no government incentives supporting re-refining or products made from re-refined base oil; and power costs are high which impacts on the energy intensive processes involved in re-refining. “Whereas Europe has a very high level of environmental awareness amongst consumers – they label their re-refined base oil with environmental endorsements – our market is primarily driven on price and re-refined oil needs to compete on price with virgin oil,” says Nyiba.
What does the future look like for SA?
South Africa is most probably the most developed re-refined oil market in Africa, followed by Egypt. Its market is estimated to be worth half a billion Rand per year and is staffed by a combined workforce of 1,500 people. There are however currently only three re-refiners in the country that produce base oil from used lubes: FFS Refiners, Flexilube, and Motolube.
“Looking ahead, ROSE would like to see South Africa follow in the footsteps of the global movement towards re-refining most used oil collected back to base oil and thereby create a closed loop system. We hope to see a growth in re-refining in South Africa, and indeed in Africa as a whole, as re-refining could be the key to unlock many doors on the continent: sustainability, job creation, reducing reliance on imports and lowering the continent’s environmental impact,” concludes Nyiba.
