New Zealand on Tuesday passed into law a unique plan to phase out tobacco smoking by imposing a lifetime ban on young people buying cigarettes.

The law states that tobacco can’t ever be sold to anybody born on or after January 1, 2009.

It means the minimum age for buying cigarettes will keep going up and up. In theory, somebody trying to buy a pack of cigarettes 50 years from now would need ID to show they were at least 63 years old.

But health authorities hope smoking will fade away well before then. They have a stated goal of making New Zealand smoke-free by 2025.

The new law also reduces the number of retailers allowed to sell tobacco from about 6,000 to 600 and decreases the amount of nicotine allowed in tobacco that is smoked.

“There is no good reason to allow a product to be sold that kills half the people that use it,” Associate Minister of Health Dr. Ayesha Verrall told lawmakers in Parliament. “And I can tell you that we will end this in the future, as we pass this legislation.”

She said the health system would save billions of dollars from not needing to treat illnesses caused by smoking, such as cancer, heart attacks, strokes, and amputations. She said the bill would create generational change and leave a legacy of better health for youth.

Lawmakers voted along party lines in passing the legislation 76 to 43.

The libertarian ACT party, which opposed the bill, said many small corner stores, known in New Zealand as dairies, would go out of business because they would no longer be able to sell cigarettes.

“We stand opposed to this bill because it’s a bad bill and its bad policy, it’s that straightforward and simple,” said Brooke van Velden, ACT’s deputy leader. “There won’t be better outcomes for New Zealanders.”

She said the gradual ban amounted to “nanny-state prohibition” that would end up creating a large black market. She said prohibition never worked and always ended with unintended consequences.

The law does not affect vaping, which has already become more popular than smoking in New Zealand.

Statistics New Zealand reported last month that 8% of New Zealand adults smoked daily, down from 16% ten years ago. Meanwhile, 8.3% of adults vaped daily, up from less than 1% six years ago.

Smoking rates remain higher among Indigenous Maori, with about 20% reporting they smoked.

New Zealand already restricts cigarette sales to those aged 18 and over, requires tobacco packs to come with graphic health warnings and cigarettes to be sold in standardized packs.

New Zealand in recent years also imposed a series of hefty tax hikes on cigarettes.

The law change was welcomed by several health agencies. Health Coalition Aotearoa said the new law represented the culmination of decades of hard-fought advocacy by health and community organizations.

A South African researcher has developed a way to remove contaminants from water used in mining that could help clean up the dirty industry. The award-winning ion exchange method not only cleans the water but captures polluting metals that can then be re-purposed.

At a Johannesburg laboratory, researchers from the University of the Witwatersrand have developed a way to clean acid mine drainage (AMD).

AMD is the runoff of pollutants like sulfuric acid and heavy metals that secrete into waterways, affecting wildlife and rural mining communities.

AMD is often found at gold and coal mines, which are plentiful in South Africa.

Tamlyn Naidu is a post-doctoral research fellow involved in the project.

“What we wanted to do is minimize environmental impact for a lot of these communities that are afflicted by AMD. They have been born into mining communities, they work in mining communities, they’re either scared to report it or to complain about it, because this is their livelihood,” she said.

The ion exchange filtration system that Naidu and her colleagues have developed uses countless polystyrene beads, each the size of a pinhead, which the water passes through.

Unlike a coffee filter, which physically blocks coffee grounds from passing through with water, the beads grab the contaminants in the water chemically.

The passing water, which can be scaled up to clean 1,000 liters an hour, then comes out clear.

“This project though, does something extra. It also wants to extract from the water valuable materials. So what has been identified in some of these streams, especially coal mining streams, is that the acid that’s produced from the mine waters actually dissolves out some rare earth metals,” says Ed Hardwick, the owner of Cwenga Technologies, which is a partner in the research.

Rare earth metals are in huge demand globally because they can be used in new technology like electric vehicles. Being able to extract them adds a financial incentive to cleaning up AMD.

Naidu said she hopes this can empower communities by monetizing the extracted materials from the AMD.

“Ultimately, from this project, we want community members to be involved in something that’s easy for them to operate, that they can extract value from and start, you know, seeing the value that companies have been taking onto the land and taken away from them. And yeah, I guess adding to their quality of life,” she says.

A method to clean up AMD that can be monetized would be good news for the government and communities that are now burdened with the costly task.

“If this was going to be an incentive, it should be on the incentive of the state and that any monies that are obtained from the separation of those minerals that can be repurposed, that can be used, is then fed back into one rehabilitation, but also two, into creating sustainable economies for the communities that are impacted,” says Tarisai Mugunyani, an attorney with the Center for Environmental Rights in Johannesburg.

Researchers say they are hopeful their filtration system, which can be adapted to clean the unique chemistry of AMD at any site, will soon be adopted widely.

It has already gained international attention with Naidu taking the first prize for emerging talents breakthroughs at the Falling Walls Science Summit in Berlin last month.

Naidu said several companies in mining and technology sectors have contacted her about becoming involved.
