 What’s the More Eco-Friendly Choice When We Take a Sip? One day, I ordered an iced coffee at a café. When I picked up my drink, I noticed something different—the straw wasn’t plastic but paper. “I guess they switched for environmental reasons,” I thought. At first, it didn’t seem like a big deal. But after a few sips, the paper straw started absorbing moisture, becoming soft and flimsy. “This is really inconvenient,” I muttered. Nowadays, many cafés and restaurants are replacing plastic straws with paper ones for a single reason: plastic straws are seen as an environmental hazard. But is plastic really such a major environmental problem? And is paper truly a better alternative? Are Plastic Straws Really the Main Culprit of Environmental Pollution? Plastic straws became a symbol of environmental destruction in 2015 when a viral video shocked the world. A marine biologist in Costa Rica filmed a sea turtle with a plastic straw lodged in its nostril, struggling to breathe as researche...

 Snack bags—technically classified as “recyclable waste.” But are they really recyclable? If you’ve read my previous post, you already know the harsh reality: snack bags are one of the least recyclable packaging types. So what can we do about it? Let’s explore the most common ideas people suggest. Rinse and Recycle—A Solution or a Waste of Time? First, rinsing and recycling. Some believe that if you rinse out snack bags before throwing them away, they have a better chance of being recycled. That sounds logical at first, but let’s take a closer look. Rinsing wastes water, it takes time and effort, and most importantly, even if you clean them perfectly, they still won’t be recycled. Be honest—how many people in the world actually wash their snack bags before throwing them away? Probably fewer than ten in a million. Even if someone does, it doesn’t change the outcome. In the end, they still end up in landfills or incinerators. Washing snack bags is nothing more than a false hope. It m...

Summary Snack bags are nearly impossible to recycle due to their fused plastic-aluminum layers. Even if rinsed, most facilities can’t process them, with recycling rates under 10%. While rinsing may reduce contamination, it doesn’t make them truly recyclable. So, if recycling isn’t the answer, what’s the alternative? The search continues in the next post.  I was standing in my kitchen, holding an empty bag of chips, staring at the oily crumbs left inside. I hesitated. Do I need to rinse this out before throwing it away? I had heard it before—"Snack bags are hard to recycle, but if you wash them first, they have a better chance of being processed properly." It sounded logical. After all, food residue can contaminate recycling batches, right? But then I paused. Wait… does rinsing actually help? Or is it just something we do to feel better about throwing things away?  So, I decided to find out. Why Are Snack Bags So Hard to Recycle? Unlike simple plastic bottles, which can be mel...

  While scrolling through the internet, I stumbled upon an interesting photo. On the left, people were tossing all their household waste into a large metal dumpster. On the right, there was no dumpster at all—just an open area where trash was left in piles. The stark contrast made me pause. What kind of waste management system is this? That question stuck with me. It made me reflect on how recycling works in Korea, where I live, on the system in Germany, which genuinely surprised me during my visit to Munich last year, and finally, on the system in the USA, where this photo was taken. How different are these three countries when it comes to recycling? Germany – When Money Drives Recycling When I first traveled to Munich, Germany, I wasn’t thinking about waste management. I was there for football—to see Kim Min-jae play in Germany and Son Heung-min in England. But one day, while staying at a guesthouse, I went to a local supermarket for water and snacks. The moment I checked out, I ...
