Apple to use zero-emission recycled aluminum in iPhone SE

By Simon Sage March 24, 2022

Apple has announced that its iPhone SE will use aluminum that has been smelted with zero greenhouse gas emissions.

Canadian manufacturing partner Elysis has been able to crank out aluminum ingots at a commercial scale and purity while only producing oxygen emissions. Since Quebec is flush with hydroelectric power, the energy used in the process is renewable too. Apple first used this aluminum with its 16-inch 2019 MacBook Pro. Research into the smelting technology was made possible by Apple’s Green Bonds. These bonds have been able to funnel investment into eco-friendly projects since 2016.

The fund is a whopping $4.7 billion, so lots of other projects are on the way. The 50 currently on the books from the 2019 fund are expected to offset 2.9 million tons of CO2. One of these projects will be building wind turbines in Denmark. These will in turn power a local Apple data center. Apple boasts that with the help of its Green Bonds, more than 175 manufacturing partners across 24 countries have pledged to only use renewable energy when making Apple products. With any luck, this will help it claim carbon neutrality along its entire production line by 2030.

Apple has been using recycled aluminum in its products since at least 2015, and claims that since then it has reduced its carbon emissions from aluminum production by almost 70%. That’s great, but recycling aluminum is low-hanging fruit. Much of commercial aluminum is already recycled since mining bauxite ore is expensive and our recycling infrastructure for aluminum is well-established.

E-waste is a much tougher problem to solve. To that end, we’re eager to see how Apple’s upcoming self-repair program pans out and expands. The longer we can keep using our devices, the longer we can keep them out of landfills.

Android does this one thing so much better than iOS, and it drives me crazy

Individual volume control sliders on a Samsung Galaxy S23

I’ve long been an iPhone user and always will be — it's just what's in my blood. Even though I’ve been dipping my toes into various Android devices since I started here at Digital Trends, my primary device is still an iPhone 14 Pro. There are a few reasons behind this decision: I’m heavily vested in the Apple ecosystem already, I bought the 1TB model to not worry about storage, and some apps I use don’t have a good enough Android equivalent.

Despite my personal choice of using iOS primarily, the more time I spend with Android, the more I notice things that it does way better than Apple’s iOS. And one of those things is how Android handles volume controls compared to iOS’ rather rudimentary and infuriating system. It may sound like a small thing to home in on, but it's something I just can't overlook.

The iPhone 14 now comes in this yellow color, and I’m obsessed with it

The iPhone 14 in yellow.

Apple announced a new iPhone this morning. No, not the iPhone 15 or the rumored iPhone 15 Ultra. Apple is refreshing the iPhone 14 and iPhone 14 Plus for 2023 with a brand-new yellow color. Rumors of the yellow color began circulating a couple of weeks ago, and on Tuesday, March 7, Apple made it official.

Reading through the press release on its website, Apple says this new yellow hue adds "even more color choices to the lineup." Per the company's vice president of Worldwide Product Marketing, Bob Borchers, "People love their iPhone and rely on it every day for all that they do, and now there’s an exciting addition to the lineup with a new yellow iPhone 14 and iPhone 14 Plus."

iPhone 15: release date and price predictions, leaks, rumors, and more

As great as the iPhone 14 and iPhone 14 Pro are, they're both already a few months old at this point, and the rumors about the iPhone 15 are well underway. We still have several months before the iPhone 15 models drop, though, as Apple usually makes iPhone announcements in the fall. In other words, there's still a lot of time for rumors to circulate around the internet.

We're keeping all of the reports and rumors of the iPhone 15 here in a single place for your convenience, but do remember to keep in mind that these are all still just speculation. Nothing is final until Apple confirms it during an official announcement. Still, a lot of the rumors give us an idea of what to expect each year, which is unfortunate if you like surprises. Here's everything we know of the iPhone 15 so far!
