If you’re searching for eco-friendly packaging solutions, you’ve likely come across the terms “compostable” and “biodegradable.” They might seem interchangeable at first glance, but there’s a world of difference between them. In this guide, we’ll break it down in simple terms—so you can make informed decisions, whether you’re a brand owner, wholesaler, or eco-conscious consumer.
What Does “Biodegradable” Really Mean?
Biodegradable simply means the product will eventually break down into natural elements like carbon dioxide, water, and biomass.
However:
- No specific time limit: A biodegradable bag could take 1 year or 100 years to degrade.
- Conditions vary: Some bags need industrial conditions to break down properly.
- Microplastics may remain: Some “biodegradable” plastics only break into tiny pieces.
In short, not all biodegradable bags are created equal. Some may leave behind residue or take years to degrade.
What Makes a Bag “Compostable”?
Compostable bags are a specific category of biodegradable materials designed to break down under composting conditions into non-toxic, soil-enriching matter.
Key features:
- Breaks down in 90-180 days under proper composting conditions.
- Leaves no toxic residue or microplastics.
- Often certified by reputable bodies like TÜV Austria, BPI, or EN 13432.
Compostable bags must meet strict international standards and are a safer choice for the environment.
Quick Comparison Table
| Feature | Biodegradable Bags | Compostable Bags |
|---|---|---|
| Breaks Down Into Natural Elements | Yes | Yes |
| Time to Degrade | Varies widely | 90-180 days (standard) |
| Leaves Microplastics? | Possibly | No |
| Certification Standards | Rarely required | Required (BPI, TÜV, EN 13432) |
| Suitable for Home Composting | Not always | Yes (if home compostable certified) |
Which Type Should You Choose?
If you care about reducing plastic waste responsibly and effectively, compostable bags are the better option.
- For businesses: Compostable bags meet more regulations and offer better branding.
- For consumers: They’re safer for compost bins, gardens, and pets.
Look for certifications when sourcing compostable bags. Avoid vague claims like “eco-friendly” or “biodegradable” without proof.
Why It Matters for Bulk Buyers
As plastic bans expand worldwide, choosing the right material matters more than ever. Wholesale buyers and importers should:
- Ask for TÜV or BPI certification
- Confirm if the bags are home or industrial compostable
- Request custom sizes or printing to align with brand values
