McDonalds sells a lot of coffee. Over a billion cups a year, to be exact. All that coffee leads to a lot of productive mornings, but it also leads to a lot of waste. Each year, millions of pounds of coffee chaff (the skin of the coffee beans that comes off during roasting) ends up getting turned into mulch. Some coffee chaff just gets burned, leading to an increase in CO2.
Now, that chaff is going to get turned into car parts. Ford is incorporating coffee chaff from McDonalds coffee into the headlamps of some cars. Ford has been using plastic and talc to make its headlamps, but this new process will reduce the reliance on talc, a non-renewable mineral. The chaff is heated to high temperatures under low oxygen and mixed with plastic and other additives. The bioplastic can then be formed into shapes.

Debbie Miewelski, senior technical leader of materials sustainability for Ford, describes it as a "win-win-win-win-win-win." The process reduces food waste, turning it into a useful, greener product. The parts are 20% lighter than the old headlamps, yet they're stronger. They also require 25% less energy during the heating and molding process.
"[Chaff] would be compostable, but in this case, we're making a high-end composite with it," Miewelski told Fast Company. "You're making a higher-end material rather than putting it back into the ground, or worst-case, creating CO2 by burning it."
The Ford x McDonald's coffee waste headlamps are an example of the circular economy. Miewelski wants to see more companies repurpose the waste from other companies in this sustainable way. "My hope is that many parts on vehicles, and many home goods, can utilize some of these materials. I'm convinced that it can happen," Miewelski told Fast Company. "We need to get people in the mindset, this is not waste, these are valuable products . . . the whole circular economy is something we should have been working on for the last 30 or 50 years, but now we have to catch up.

This bioplastic will be first used in the Lincoln Continental sedan in 2020. Ford hopes to use the material in more cars and more parts. The company has a goal to use only recycled and renewable plastics in its cars. The transportation sector is currently responsible for over 25% of all carbon emissions, so the greener we can make our vehicles, the better.

Grieving couple comforting each other
This response to someone grieving a friend might be the best internet comment ever
When someone is hit with the sudden loss of a friend or loved one, words rarely feel like enough. Yet, more than a decade ago, a wise Redditor named GSnow shared thoughts so profound they still bring comfort to grieving hearts today.
Originally posted around 2011, the now-famous reply was rediscovered when Upvoted, an official Reddit publication, featured it again to remind everyone of its enduring truth. It began as a simple plea for help: “My friend just died. I don't know what to do.”
What followed was a piece of writing that many consider one of the internet’s best comments of all time. It remains shared across social media, grief forums, and personal messages to this day because its honesty and metaphor speak to the raw reality of loss and the slow, irregular path toward healing.
Below is GSnow’s full reply, unchanged, in all its gentle, wave-crashing beauty:
Why this advice still matters
Mental health professionals and grief counselors often describe bereavement in stages or phases, but GSnow’s “wave theory” gives an image more relatable for many. Rather than a linear process, grief surges and retreats—sometimes triggered by a song, a place, or a simple morning cup of coffee.
In recent years, this metaphor has found renewed relevance. Communities on Reddit, TikTok, and grief support groups frequently reshare it to help explain the unpredictable nature of mourning.
Many readers say this analogy helps them feel less alone, giving them permission to ride each wave of grief rather than fight it.
Finding comfort in shared wisdom
Since this comment first surfaced, countless people have posted their own stories underneath it, thanking GSnow and passing the words to others facing fresh heartbreak. It’s proof that sometimes, the internet can feel like a global support group—strangers linked by shared loss and hope.
For those searching for more support today, organizations like The Dougy Center, GriefShare, and local bereavement groups offer compassionate resources. If you or someone you know is struggling with intense grief, please reach out to mental health professionals who can help navigate these deep waters.
When grief comes crashing like the ocean, remember these words—and hang on. There is life between the waves.
