United Kingdom testing durable roads made of recycled plastic

Despite the fact that road vehicles have changed enormously over the past 70 years — in both quality and quantity — the roads they drive on have advanced surprisingly little.

U.K. entrepreneur and engineer Toby McCartney has been working to change that, courtesy of technology that allows for the creation of high quality road asphalt out of recycled plastic waste. With the innovative tech, he now wants to use discarded plastic from landfills to transform millions of kilometers of roads around the world.

“We take waste plastic that is destined for landfill sites and recycle it,” McCartney told Digital Trends. “What we’re able to do is to take this plastic that has been thrown away, and use a special formula to clean it off, create pellets using it, and then use those pellets to add to a mixture of rocks and bitumen to make longer-lasting roads.”

So far, the scheme has won the approval of Virgin founder Sir Richard Branson, and McCartney’s company MacRebur has gotten the support of two local governments in England to start using its MR6 product to build their roads.

McCartney describes the technology as a “real win-win across the industry.” It lessens the reliance on fossil fuels due to the reduction in oil that needs to be used as part of the formulation, helps cut down on waste plastic going to landfill, and improves the streets we drive on. The plastic-based road asphalt made by MacRebur is 60 percent tougher than standard asphalt. By tweaking the recipe, the surface can also be modified for different environments.

In addition, it saves money for all involved. Companies that sell the waste plastic to McCartney save money by not being taxed for sending material to landfill. Local governments save money because they get a longer-lasting road which needs less maintenance. Drivers save money because they’re driving on better roads, with fewer potholes. And McCartney and his colleagues save money because, well, they’re being paid for their work.

Next up, he says the plan is to expand to new countries — although he noted that this must be done the right way.

“Something we’re very conscious of is that we’re still classed as a startup,” McCartney said. “We don’t want to grow too quickly, because we want the infrastructure in place to produce our pellets. We’re aware of dealing with over-demand, which would leave us unable to fulfill orders. As a result, we’re being very careful in selecting the countries that we’re expanding into.”

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
