What's the difference between biodegradable and compostable? 🌱

In the world of sustainable packaging, the terms “biodegradable” and “compostable” are often used as synonyms. However, they do not mean the same thing. Understanding their differences is key to choosing the most suitable packaging, complying with regulations, and conveying the correct message to the consumer.

🔍 What does it mean for a material to be biodegradable?

A biodegradable material is one that can decompose naturally through the action of microorganisms (bacteria, fungi, enzymes), transforming into simple elements such as carbon dioxide, water, and biomass.

Characteristics:

• The process can take from weeks to years, depending on the material and conditions (humidity, temperature, oxygen).
• It does not always require a composter, but it does not guarantee that it leaves no toxic residue.
• A biodegradable plastic can still be plastic, even if it degrades faster.

Example: A biodegradable plastic bag may take months to disappear, but it does not necessarily turn into compost.

♻️ And what does compostable mean?

A compostable material is always biodegradable, but with more specific and demanding conditions:
It decomposes in a controlled environment (industrial or domestic) in a short period, and it does so without leaving toxic residues, generating compost useful as natural fertilizer.

Characteristics:

• The process must normally be completed in less than 180 days in industrial facilities.
• It leaves a clean residue, compatible with agriculture or gardening.
• To be considered compostable, it must be certified according to certain standards, such as EN 13432 in Europe, which guarantee that the material degrades under controlled conditions within a specific time (usually 90 to 180 days).

🧠 Visual summary: biodegradable vs compostable

Why is this difference important?

Choosing between biodegradable or compostable directly affects waste management, customer communication, and regulatory compliance. Some key points:

• Avoid greenwashing: Some brands use terms like “eco-friendly” or “green” without regulatory backing. That is why it is important to look for recognized certifications.
• Comply with the law: European regulations require specific certifications to use the term "compostable".
• Consumer education: your customers will know how to correctly dispose of the packaging if the message is clear.

   No. All compostable material is biodegradable, but not everything biodegradable is compostable.
2. How long does it take for a compostable material to decompose?
   Normally between 90 and 180 days under controlled composting conditions.
3. What happens if I throw a compostable item in the regular trash?
   It may end up in a landfill and not decompose properly. Ideally, it should be managed in composting systems.
4. How do I know if a product is truly compostable?
   Look for recognized certifications such as EN 13432, OK Compost, or Seedling.
5. Why is it not enough for something to be biodegradable?
   Because it may take too long to degrade or generate microplastics in the process.
6. Are Bicopack meshes compostable?
   Yes. They are made with natural fibers that comply with compostability regulations, turning into fertilizer at the end of their useful life.
