Compostable Bags vs. Biodegradable Bags: What's the Difference?

In the quest to lead a more sustainable lifestyle and minimize their individual environmental impact, many homeowners and renters in the U.S. are actively seeking alternative solutions to traditional plastic waste bags. Two of the most popular terms that they may have encountered are "compostable bags" and "biodegradable bags." While they may seem interchangeable at first glance, these terms refer to distinct properties and decomposition processes that make a significant difference when it comes to eco-friendly waste management at home.

Understanding the key differences between these two types of bags is crucial to make informed, environmentally responsible decisions when choosing a product for household waste disposal. Compostable bags, like those provided by Plastno, are specifically designed to break down into nutrient-rich compost under the right conditions, making them a superior choice for sustainable waste management. 

In the following sections, we will explain in detail the distinguishing features of compostable and biodegradable bags, explore the benefits of compostable bags for home waste management, and provide tips on how to successfully implement the use of compostable bags in your daily life. By the end of this article, you will have a comprehensive understanding of why compostable bags are the ultimate choice to help you minimize your environmental impact and contribute to a more sustainable future.

Understanding Compostable Bags

Compostable bags provide an eco-friendly alternative to traditional plastic bags, specifically designed to decompose into nutrient-rich compost in a relatively short timeframe when exposed to appropriate composting conditions. Key features of compostable bags include:

  1. Material Composition: Compostable bags are made from non-GMO, renewable plant-based materials, ensuring a sustainable and environmentally friendly product.
  1. Decomposition Process: Properly disposed of compostable bags will break down into carbon dioxide, water, and biomass within 90 to 180 days under industrial composting systems or within a larger timeframe under home composting conditions.
  1. Certification Standards: Certified compostable bags, like the ones by Plastno, adhere to stringent ASTM D6400 standards, ensuring their ability to compost fully and safely without leaving harmful residues.
  1. Applications: Compostable bags can be used for various purposes like collecting food waste, disposing of yard debris, and lining wastebaskets, impacting the environment positively when used correctly.

Understanding Biodegradable Bags

Biodegradable bags are often marketed as an environmentally friendly alternative, but their decomposition process can be inconsistent and potentially detrimental to the environment. Key features of biodegradable bags include:

  1. Material Composition: Biodegradable bags can be made from various materials, including plastic blends, and may contain additives that enable the breakdown of the material.
  1. Decomposition Process: Unlike compostable bags, the decomposition process for biodegradable bags doesn't have a specific timeframe and can vary widely. Also, biodegradation can result in the generation of harmful microplastics.
  1. Certification Standards: Biodegradable bags lack a universal standard for certification, leading to confusing claims and unreliable performance.
  1. Applications: Biodegradable bags may be used for a range of applications, but their inconsistent decomposition can cause issues in recycling and composting systems.

Key Differences Between Compostable and Biodegradable Bags

Now that we've outlined the characteristics of compostable and biodegradable bags let's explore their key differences:

  1. Material Composition: Compostable bags are made from renewable plant-based materials, whereas biodegradable bags may consist of plastic blends or materials that don't decompose as efficiently.
  1. Decomposition Process and Timeframe: Compostable bags are designed to decompose into nutrient-rich compost under specific conditions, while biodegradable bags lack a definitive timeframe and may leave harmful microplastics in the environment.
  1. Standards and Certifications: Compostable bags have stringent certification standards that guarantee their eco-friendly performance, while biodegradable bags lack such regulations, leading to unreliable claims and inconsistent results.
  1. Environmental Impact: Compostable bags contribute positively to the environment by producing valuable compost, while biodegradable bags can cause harm due to their potential to form microplastics that negatively impact ecosystems.

Choosing Compostable Bags for Home Waste Management

For homeowners and renters in the U.S. committed to sustainable waste management, choosing compostable bags over biodegradable bags is an environmentally responsible decision. Here's how to use compostable bags successfully in your household:

  1. Select Certified Compostable Bags: Choose bags with valid certifications, like the ASTM D6400 standard, to ensure a truly eco-friendly product.
  1. Use Compostable Bags for Suitable Waste: Plastno's compostable bags are ideal for collecting and disposing of food waste, yard debris, and other compostable materials.
  1. Establish a Home Composting System: Set up a composting system at home or participate in a community composting program to ensure that the compostable bags break down efficiently.
  1. Educate Family Members: Teach household members about proper waste disposal and the importance of using compostable bags to minimize environmental impact.


Understanding the crucial differences between compostable and biodegradable bags enables homeowners and renters to make informed, eco-friendly decisions when it comes to waste management.
