Compostable or Biodegradable: What's the Difference and Why Does It Matter?
Understanding the False Friends of Sustainable Development
Many products are labeled "biodegradable," but that doesn't mean they're actually environmentally friendly. The truly sustainable alternative? Compostable bags .
Biodegradable Bags: A Misleading Term
Not all biodegradable bags disappear completely!
- Many require specific conditions (temperature, humidity, bacteria) to decompose .
- Some fragment into microplastics , polluting soils and oceans.
- No clear standard : the term "biodegradable" does not guarantee rapid degradation.
Compostable Bags: The Real Eco-Friendly Alternative
🌱 Unlike classic biodegradable bags, compostable bags are EN 13432 certified , guaranteeing:
✅ Complete decomposition in a few months in industrial or domestic compost.
✅ Zero microplastics or toxic residues.
✅ A virtuous cycle that enriches the soil instead of polluting it.
| Features | Biodegradable Bags | Compostable Bags |
|---|---|---|
| Degradation time | Months to years | 3 to 6 months |
| Microplastics? | Possible | None |
| European standard? | No | Yes (EN 13432) |
| Impact on soils | Potential pollution | Soil fertilization |
