When upgrading your home’s insulation, one of the biggest questions homeowners face is: Can old insulation be recycled? Whether you’re dealing with aging fiberglass, outdated cellulose, or deteriorating spray foam, understanding your options for eco-friendly disposal is key. At Koala Insulation of Chicago-Western Suburbs, we’re committed to sustainability and helping homeowners make informed, responsible choices for their home and the environment.

This blog will explore the different types of insulation, whether they can be recycled, how the recycling process works, and how to responsibly handle insulation removal and replacement.

Why Replace Old Insulation?

Insulation doesn’t last forever. Over time, it can become less effective due to:

• Moisture damage (especially in basements and attics)
• Pest infestations
• Compression or settling
• Mold or mildew growth
• Aging and deterioration

If your insulation is more than 15–20 years old or your energy bills have been rising, it may be time for an upgrade. But once it’s removed, what happens to that old material?

Common Types of Insulation and Their Recycling Potential

Let’s break down the recyclability of the most common insulation materials:

🟪 Fiberglass Insulation

Can it be recycled?
Yes—fiberglass insulation is technically recyclable, but it’s not always accepted by standard curbside recycling programs.

How is it recycled?
Fiberglass can be melted down and reformed into new insulation or other fiberglass-based products like roofing tiles or reinforcement materials. However, the process is energy-intensive, and not all recycling centers are equipped for it.

Challenges:
Contamination with dust, mold, or debris may disqualify old fiberglass from recycling.

🟨 Cellulose Insulation

Can it be recycled?
Yes, cellulose—typically made from recycled newspaper—is one of the most eco-friendly insulation options. However, once installed, it’s difficult to extract and recycle again due to its loose-fill nature and potential contamination.

Best option:
Composting or repurposing as mulch or packing material (if clean) is sometimes possible. Industrial-scale recycling facilities may accept larger volumes.

🟥 Spray Foam Insulation

Can it be recycled?
Unfortunately, spray foam is not recyclable in the traditional sense. Once cured, it becomes a rigid plastic material that cannot be melted down or reformed.

Disposal methods:
Spray foam must be carefully removed and disposed of in accordance with local construction waste regulations. Some facilities can incinerate it for energy recovery.

🟦 Mineral Wool (Rockwool) Insulation

Can it be recycled?
Yes, mineral wool can be recycled, but only in specific facilities. It is made from molten rock or slag spun into fibers and can be reused in manufacturing new insulation.

Limitations:
Like fiberglass, it must be clean and uncontaminated to be eligible for recycling.

How Koala Insulation of Chicago-Western Suburbs Handles Old Insulation

At Koala Insulation of Chicago-Western Suburbs, we take great care in properly removing and disposing of old insulation. Here’s how we approach it:

1. Evaluation and Safety

Before removal, our technicians assess the condition of the insulation to determine if it’s salvageable, recyclable, or requires special disposal due to contamination (e.g., mold or rodent droppings).

2. Professional Removal

We use HEPA-filtered vacuums and proper protective gear to safely extract insulation while minimizing airborne particles and environmental impact.

3. Eco-Conscious Disposal

Where possible, we coordinate with local recycling centers or waste-to-energy facilities to divert insulation from landfills. In cases where recycling isn’t an option, we ensure the materials are disposed of in accordance with Illinois environmental regulations.

Tips for Homeowners: Recycling and Disposal Do’s and Don’ts

If you’re considering removing insulation on your own (which we typically don’t recommend for health and safety reasons), here are a few do’s and don’ts to follow:

✅ DO:

• Contact local recycling centers or your city’s waste management office to ask about insulation disposal options.
• Keep removed insulation separated by type to increase recyclability.
• Wear proper protective equipment (gloves, mask, goggles) when handling insulation.
• Use heavy-duty bags and label them clearly.

❌ DON’T:

• Throw old insulation into your regular trash bin without checking local guidelines.
• Attempt to recycle contaminated or moldy insulation.
• Burn insulation—it can release toxic chemicals, especially spray foam.
• Assume all insulation types are recyclable—check with a professional like Koala Insulation.
