This machine pulverizes glass bottles, turns them into fine-grain sand in just 5 seconds

How do you dispose of a bottle of beer once you’re done drinking it? You crush it into fine-grain sand, right?

Well, thanks to a smart new promotion created by New Zealand brewers DB Breweries — working alongside the ad agency Colenso BBDO New Zealand — it’s possible to do exactly that.

“Two thirds of the world’s beaches are retreating as people across the world use non-renewable beach sand for construction, roading and other uses,” Simon Smith, brand PR and digital manager for DB Breweries, told Digital Trends. “We had some [conversations] over beers, and came up with an idea to crush glass bottles into a sand substitute that can be used in things such as construction, roading, even golf bunkers; meaning that we can keep our beautiful beach sand where it belongs: on our beaches.”

New Zealand, Smith said, has a pretty impressive recycling rate, although there’s always room to do more. To that end, DB Breweries has built several machines able to take empty bottles and turn them into substitute sand. All a drinker needs to do is deposit his or her bottle in the machine, which then uses miniature steel hammers to crush it into 200 grams of sand in only five seconds — after extracting the plastic labels with a vacuum system.

“Our sand will be processed through a screener which sorts it into a fine grades between 1.1 – 0.4mm particle sizes,” he continued. “Over the next few months, we’ll be creating up to 100 tons of sand, which is the equivalent of 500,000 DB Export Bottles. The resulting sand substitute will then be given to our construction and retail partners to use in place of beach sand.”

The ultimate goal is to provide a way of prompting people to recycle by giving them an image of what exactly it means to do so, rather than leaving it as an abstraction. “Our ambition for the campaign is for people to have something tangible to think about, such as the love of our beautiful beaches, as a reminder to recycle,” he said.

Hey, if it means we get to drink and save the planet, who’s losing out? Aside from our liver and bank balance, that is…

Robots just ran the Beijing half-marathon faster than the world record holder

A humanoid robot just ran a half-marathon faster than the world record holder. It might not seem impressive at first, but considering last year, the fastest robot at Beijing's humanoid robot half-marathon finished in two hours and 40 minutes, this is a huge achievement. 

As reported by the Associated Press, the winning robot at this year's Beijing half-marathon crossed the finish line in 50 minutes and 26 seconds, comfortably beating the human world record of 57 minutes recently set by Jacob Kiplimo.

AI is already changing how the world works, but it’s also quietly making one of our biggest environmental problems even worse. And no, this isn’t about energy consumption this time. It’s about the hardware. Because every smarter AI model comes with a physical cost.

AI is about to supercharge the e-waste problem

Smart glasses are finding a surprise niche — Korean drama and theater shows
Urban, Night Life, Person

Every year, millions of people follow Korean content without speaking a word of the language. They stream shows with subtitles, read translated lyrics, and find workarounds. But live theater has always been a different problem — you can't pause or rewind it. That's the problem: a Korean startup thinks it's cracked, and Yuroy Wang was one of the first to try it. The 22-year-old Taipei retail worker is a K-pop fan who loves Korean culture but doesn't speak the language. When he went to see "The Second Chance Convenience Store," a touring play based on a Korean novel that was a bestseller in Taiwan, he expected supertitles. What he got instead was a pair of chunky black-framed AI-powered glasses sitting on his nose, translating the dialogue in real time directly on the lenses. "As soon as I found out they were available, I couldn't wait to try them," he said. Wang is part of a growing audience discovering that smart glasses, a category of tech that has struggled to find mainstream purpose for years, might have just found their calling in the most unexpected of places: live Korean theater.

How do the glasses work?
