ZERO WASTE NOTES · PART 08 Upcycling vs. Downcycling: Not All Recycling Is Equal

The word “recycling” covers a wide range of outcomes. A plastic bottle turned into new clothing and a plastic bottle turned into carpet are both technically recycling — but they're moving in opposite directions.

1. What Upcycling Means

Upcycling takes discarded materials or byproducts and, through design and craftsmanship, turns them into something with more value than the original. In Korea it's also called saehwalyong (“new use”).

The key isn't just changing the shape of something — it's improving the material's quality or usefulness. Making new fabric from scratch involves extracting raw material, spinning, dyeing — multiple resource- and energy-intensive steps. Upcycling skips all of that by working directly with material that already exists, which is why it's credited with reducing overall resource consumption.

Swiss bag brand Freitag is a well-known example, cutting up old truck tarps to make bags. Every panel has a different pattern, so every bag is one of a kind — a textbook case of upcycling.

2. Downcycling — Recycling That Loses Quality

Downcycling is recycling that produces a lower-quality material or product than the original. Grinding up used plastic bottles into carpet fiber or low-grade filler material is a common example.

There's a reason this happens. Every time plastic gets recycled, the polymer chains that hold it together break down a little more. So the same plastic bottle loses strength and purity with each recycling pass. What started as a beverage bottle becomes fiber, then filler, and after a few rounds of downcycling, it can no longer be recycled at all — at which point it's incinerated or landfilled. Which is exactly why “this got recycled” isn't the reassurance it sounds like.

3. Upcycling in Practice

Upcycling isn't hard to find in Korea.

·         Pleats Mama — spins recycled plastic bottles into yarn for bags. One shoulder bag reportedly uses about 16 500ml bottles.

·         RE;CODE — Kolon FnC's upcycling brand, which breaks down unsold clothing inventory over three years old, along with military tents, parachutes, and defective airbags, and rebuilds them into new products. It's a clear example of giving new purpose to material that was headed for incineration.

·         Seoul Upcycling Plaza (Seongdong-gu, Seoul) — a space where you can see and buy products made from industrial byproducts like used banners and leather scraps.

·         Reworked denim — cutting up old jeans into bags or pouches is a form of upcycling anyone can try at home.

4. What Consumers Should Know

A “recycled” label alone isn't enough to call something a good choice. How resources circulate — and how many times — depends on whether it's upcycling or downcycling.

Downcycling isn't inherently bad. Getting one more use out of material headed for a landfill or incinerator still matters.

Upcycling isn't a perfect answer either. Disassembling, cleaning, and redesigning materials by hand takes labor, which makes mass production difficult and prices comparatively high. Realistically, it's less “the easy answer for everyone” and more one option among several.

Downcycling has real limits. Upcycling genuinely extends a resource's life, but with limited accessibility. Knowing that much already gives you one more standard to weigh when making a purchase.

A reasonable starting point: look around your home today for something that could have a second life as an upcycled object.

Is there something at home you'd want to try upcycling?
