Although many assume compostable and biodegradable packaging are identical, they are not. In reality, they differ markedly, and understanding these differences will help you select the packaging material best suited to your needs.

Understanding compostable vs biodegradable differences helps you create a product that’s better for your business and the planet. Since many people still confuse the two, here are five key aspects that highlight their differences.
Packaging materials are often labelled as either biodegradable or compostable, but these terms are not interchangeable. Each has distinct breakdown processes, environmental impacts, and disposal requirements that affect how effectively they reduce waste and support sustainability.
Biodegradable products break down through the action of living microorganisms, such as bacteria or fungi, turning into naturally occurring compounds over time. However, the process lacks a defined timeframe, meaning some materials may take years to fully decompose under various conditions.
Unlike biodegradable, compostable products break down quickly into natural, non-toxic elements, much like typical organic waste. They require specific conditions to produce compost made of carbon dioxide, water, inorganic compounds, and nutrient-rich biomass.
Biodegradable materials break down through the action of microorganisms, but their decomposition lacks a defined timeline. Depending on the environment, they may take months, years, or even centuries to degrade, and the process does not guarantee a complete or harmless breakdown.
In contrast, compostable materials are designed to decompose within a specific period, typically around 180 days, under controlled conditions, such as those in industrial composting facilities. When properly treated, they decompose into natural components without releasing harmful residues.

Biodegradable materials may break down unevenly, often leaving behind harmful residues like microplastics or toxic compounds. This incomplete degradation is common when materials are exposed to unsuitable conditions, making them less environmentally friendly than the term might suggest.
Meanwhile, biodegradable materials are intended to completely disintegrate into non-toxic, natural elements. When processed correctly, they leave no harmful residue and even produce nutrient-rich compost that enhances soil health and supports sustainable waste management.
When looking at compostable vs biodegradable packaging differences, one major factor is the conditions needed for decomposition. Biodegradable materials can degrade in soil, water, or landfills, but often at unpredictable rates and sometimes incompletely if conditions aren’t ideal.
Compostable materials need specific conditions to decompose effectively, including controlled heat, moisture, oxygen, and microbial activity. These requirements are typically met in industrial composting facilities, while home composting may only work if the product is certified as “home-compostable.”
Biodegradable labeling is often vague and can mislead consumers, as it lacks standardised testing methods and defined timelines for breakdown. This ambiguity sometimes results in regulatory restrictions and creates confusion about the product’s actual environmental impact.
Compostable labeling, however, is subject to strict certification standards such as ASTM D6400, D6868, or EN 13432. These ensure the product decomposes within a set timeframe, leaves no harmful residue, and meets clearly defined environmental criteria for composting.

A survey of 487 U.S. grocery shoppers found that while 38% reported purchasing biodegradable packaging, 30% had purchased compostable packaging. This suggests growing consumer interest, even though awareness and availability may still be limited.
For this reason, a lingering question remains: which is better for packaging, compostable vs biodegradable packaging? While both are often seen as environmentally friendly, it’s essential to understand their differences and choose the one that best meets your product’s needs.
Both compostable and biodegradable describe how materials break down, but they vary significantly. Compostable items are always biodegradable; however, many biodegradable products cannot be composted. Compostable materials meet strict standards for safe decomposition, while biodegradable ones break down slowly.
Compostable packaging decomposes within a controlled timeframe, produces nutrient-rich compost, and avoids releasing harmful substances. Biodegradable packaging, lacking strict requirements, often cannot be composted effectively and is more likely to end up in landfills, providing fewer environmental benefits overall.

Choosing between compostable and biodegradable packaging comes down to understanding their true impact and proper disposal methods. Compostable packaging offers clearer benefits when managed correctly, while biodegradable options often lack defined standards.
Always check certifications, follow guidelines, and opt for solutions that genuinely reduce environmental harm. By choosing certified compostable options and encouraging local composting initiatives, you help protect the planet.
