Compostable vs Biodegradable Packaging: Understanding the Differences
In response to the increasing consumer preference for environmentally friendly packaging, many brands are now exploring sustainable packaging options such as compostable and biodegradable packaging. While these terms are often used interchangeably, they have distinct differences that are important to understand when making sustainable packaging decisions.
What is biodegradable packaging?
Biodegradable packaging is made of materials that can break down naturally through the action of microorganisms.These microorganisms can include bacteria, fungi, and other living organisms that organically break down into simple, non-toxic substances such as carbon dioxide, water, and biomass. The breakdown process takes time and is influenced by factors such as temperature and humidity.
Biodegradable packaging can be a suitable alternative to traditional plastic packaging, which can take hundreds of years to decompose and have harmful effects on the environment. Plant-based and petroleum-based materials that have been modified for easier breakdown are often used in biodegradable packaging.
What is compostable packaging?
Compostable packaging is designed to break down completely in a composting environment within weeks or months. Composting occurs naturally when organic materials are broken down by microorganisms and turned into nutrient-rich soil. Compostable packaging is typically made from plant-based materials, such as cornstarch, sugarcane, or bamboo, and other natural fibers and binders that contribute to the composting process.
Key Differences Between Compostable vs Biodegradable Packaging
There are several important differences between compostable and biodegradable packaging, including time frame, end result and materials.
Time frame
Compostable packaging breaks down much faster than biodegradable packaging.
End result
Compostable packaging breaks down completely and becomes soil, while biodegradable packaging breaks down into smaller pieces of inorganic material that never fully decomposes.
Materials
Compostable packaging is typically made from plant-based materials, while biodegradable packaging can be made from various materials, including petroleum-based ones.
How To Choose Between Compostable vs Biodegradable Packaging
When deciding between compostable and biodegradable packaging, there are several factors to consider:
Environmental impact: Biodegradable packaging is often made from petroleum-based materials, while compostable packaging can be made from plant-based materials. Although biodegradable packaging has a smaller carbon footprint than plastic, it doesn’t break down completely and still leaves some inorganic waste behind.
End-of-life options: If a consumer brand decides to go with biodegradable packaging, they should detail the consumers with information on how to dispose of the product properly. If a brand uses compostable packaging, they should also provide clear instructions on how the product can be composted at home.
Product requirements: Some brands may have specific product requirements that make biodegradable and compostable packaging more difficult to use. For example, if a brand needs to keep its products cold for an extended period of time, the packaging may need to be made from materials that can insulate heat. If the product is highly acidic or alkaline, this can also make biodegradable and compostable packaging more difficult to use.
Brands using compostable packaging should provide clear instructions on how to compost the product properly, while those using biodegradable packaging should provide instructions on how to dispose of it.
In conclusion, understanding the differences between compostable and biodegradable packaging is important for making informed packaging decisions that are both sustainable and suitable for the needs of the product and customers.
