# Is compostable packaging worse for the environment if it's landfilled?

**Short answer:**  
No—compostables are generally _not worse_ than conventional plastic if landfilled, but landfill is **not their intended or best end-of-life**.

**Here’s the nuanced reality:**

Compostable packaging is designed to break down through biological processes into carbon dioxide, water, and biomass **when it reaches a composting environment**. That’s where it delivers its full environmental benefit.

If a compostable package instead ends up in a landfill:

* It does **not behave like conventional plastic**, which persists indefinitely and fragments into microplastics.
* It does **not introduce long-lived synthetic polymers** into soil or water systems.
* It typically remains biologically inert or degrades slowly, similar to other organic materials under low-oxygen landfill conditions.

In other words, **it does not create additional long-term harm compared to plastic**—but it also doesn’t deliver its intended upside.

**The key distinction is opportunity cost, not added damage.**

Plastic in a landfill creates a permanent environmental burden.  
Compostable packaging in a landfill represents a **missed opportunity** to:

* Capture food waste
* Reduce methane from organics diversion
* Return nutrients to soil

That’s why compostables are best paired with:

* Composting access
* Clear labeling and education
* Policies like EPR that fund composting infrastructure

When those systems are in place, compostables reach their highest and best use: **closing the organic loop rather than contributing to permanent waste.**
