Vital move to sharpen up recycling in KZN
Smoke and mirrors stuff must be cleanly dealt with
GLASS recycling in South Africa is a “disaster”, particularly in Kwazulunatal (KZN) where only a tiny fraction of the stuff is reprocessed.
Part of the problem is that producing glass from virgin materials remains too cheap.
Glass-makers do not bear the real environmental cost of extracting the raw materials – chiefly river sand – which is illegally mined.
That’s the view of Dr Andrew Venter, the outgoing chief executive officer of the Wildlands Conservation Trust (Wildtrust), one of the country’s largest environmental not-for-profit organisations.
Venter said it made little financial sense for the manufacturers to buy recycled materials to make new glass.
“There’s about 20 million kilograms of glass that come into KZN every month.
“Of that, less than 1 million kilograms get recycled.
“It’s smoke and mirrors from the industry – they don’t want you to know that in KZN, the recycling rate is less than 5%,” he said.
The good news is that there are alternatives, and Venter has committed himself to putting a few into action. The 51-year-old leaves the Wildtrust after 19 years at the helm and will be taking over the trust’s Recycling for Life project.
The project has over 500 “waste-preneurs” and an extensive network of schools and businesses that collect about 4 200 tons of trash a year. Glass accounts for about 50% of this.
“We’re trying to shift the glass recycling model to a model where glass is crushed and used as a substitute for filter-type mechanisms,” Venter said.
Currently filter glass is imported into South Africa.
When it comes to plastic, the recycling figures are on a par with glass. Again, Venter reckons a new approach was needed.
“About 60% of plastic is unrecyclable, the other 40% is recyclable, but of that only about 43% is actually recycled.
“If you start doing that 100%, you’re sitting at the reality that about 15% of plastic is recycled. The rest is not, either because it can’t be or it’s just not,” he said.
What can be done? “We’ve demonstrated that it’s possible, at a local level, to take ice-cream containers, margarine containers, yoghurt containers, put them in one end of a machine and get diesel out the end, which you can put into cars.
“The plastic started as fuel, so to get it back to that stage closes the loop,” said Venter.
Recycling for Life has been successful in taking unrecyclable plastic trash and combining it with glass to make building materials, such as bricks and pavers, says Venter.
In theory, you could put up a plant in a town and “that town can become litter-free because you just suck up that plastic material”.
Venter said he had been in talks with the Wildtrust over the past year to structure his departure. At the same time, the board had expressed doubts about its ability to continue with the recycling.
“And so, the conversation was whether I could take that with me to continue that,” said Venter.
Initially, he would work on restructuring Recycling for Life so that it could continue operations and then pursue “some really interesting innovations”, like the filter glass and plasticto-diesel ideas.
He suspects that he might still be involved with recycling when he’s “older and greyer” but insists it’s not his real aim.
“I’m not setting up a recycling business.
“My priority is to find and shape a new role where I have the ability to influence sustainability change at a business leadership and corporate level in South Africa into Africa,” he said.
“Like getting Unilever to say that they’re only going to use recyclable plastic. Roughly 35% of the material they put out is unrecyclable.
“If they switch that off, at the scale they’re operating, that requires massive change.
“So those policy shifts are vital, and where I would like to focus,” said Venter.
In recent public statements, Unilever has declared by 2025 all of its packaging will recyclable or decomposable. | Additional reporting, Matthew Hattingh and Fred Kockott, Roving Reporters
