Everything You Need to Know About Compostable Liners

Composting is a simple yet impactful way to reduce waste and contribute to a healthier planet. For those who compost at home or in shared spaces, compostable liners can make the process more convenient, clean, and manageable. But what exactly are compostable liners, how do they work, and why should you use them? In this comprehensive guide, we’ll cover everything you need to know about compostable liners, so you can make informed and eco-friendly choices for your composting routine.

What Are Compostable Liners?

Compostable liners are bags designed specifically to line compost bins or containers. Unlike traditional plastic bags, compostable liners are made from materials such as plant starches or other biodegradable substances. These materials are formulated to break down naturally in a composting environment, leaving behind no toxic residue or microplastics.

Using compostable liners simplifies the task of managing food scraps and organic waste. They help keep compost bins clean while making it easier to transport waste to larger composting systems or municipal collection programs.

Why Use Compostable Liners?

There are several reasons to incorporate compostable liners into your composting routine:

• Convenience: Compostable liners make it easier to collect and transport organic waste without dealing with leaks or messes.
• Hygiene: Liners help keep compost bins clean and reduce unpleasant odors, especially in indoor or countertop compost bins.
• Eco-Friendliness: Unlike regular plastic bags, which can contaminate compost, compostable liners break down completely, aligning with sustainable living goals.
• Compliance: Many municipal composting programs require the use of certified compostable bags to ensure proper decomposition.

How Do Compostable Liners Work?

Compostable liners are designed to break down under certain conditions, such as those found in home composting systems or industrial compost facilities. These conditions typically include heat, moisture, and microbial activity.

When placed in a composting environment, the materials in compostable liners degrade into water, carbon dioxide, and organic matter. Depending on the type of composting system and liner material, this process can take anywhere from a few weeks to a few months.

Choosing the Right Compostable Liners for Your Needs

Not all compostable liners are created equal. When selecting a liner, consider the following factors:

1. Size

The size of your compostable liner should correspond to the size of your compost bin. For smaller indoor setups, such as countertop compost bins, opt for small compostable bags. For larger outdoor bins, choose liners designed to fit the volume of your container.

2. Material

Most compostable liners are made from plant-based materials like cornstarch or PLA (polylactic acid). Look for products that are certified compostable by organizations like the Biodegradable Products Institute (BPI) or meet ASTM standards for compostability. This ensures they’ll break down as intended without leaving harmful residues.

3. Thickness

Heavier-duty compostable liners are better suited for larger bins or situations where the waste may be wetter or heavier. For example, our 35-gallon compostable can liner is designed for durability and leak resistance, making it ideal for high-volume use.

4. Compatibility with Your Composting System

Some liners are better suited for industrial composting facilities, while others are designed specifically for home composting systems. Make sure to check the product’s specifications and certifications to confirm compatibility with your setup.

Best Practices for Using Compostable Liners

To get the most out of your compostable liners, follow these tips:

• Don’t Overfill: Overloading the liner may cause it to tear or leak. Leave enough room at the top to tie it securely.
• Avoid Excess Moisture: While compostable liners are designed to handle organic waste, excessive liquid can weaken the material. Drain excess liquid from food scraps before placing them in the liner.
• Use Promptly: Compostable liners can start breaking down if left in a damp bin for too long. Empty your compost bin regularly to maintain cleanliness and prevent premature degradation.
• Check Local Guidelines: If you’re using a municipal composting program, ensure that your liners meet local requirements. Some programs may have specific certifications they accept.

Compostable Liners vs. Biodegradable Liners: What’s the Difference?

It’s important to understand the distinction between compostable liners and biodegradable liners:

• Compostable Liners: These are specifically designed to break down in a composting environment and contribute to nutrient-rich compost. They are certified to meet strict standards for compostability.
• Biodegradable Liners: While biodegradable liners may eventually break down in the environment, they don’t necessarily decompose completely or safely in a composting system. Some biodegradable products may leave behind microplastics or other residues.

For composting, always choose liners labeled as compostable to ensure they align with your sustainability goals. Learn more about our selection of compostable bags to find the right option for your needs.
