How Long Does Fiberglass Take To Decompose? Manufacturer’s Guide

Offering sustainable products is mandtory in today’s climate (literally). Many of our stakeholders want to know – how long does fiberglass take to decompose and is it environmentally friendly? In fact, Fiberglass can take up to 50 years to decompose, making it a great long-lasting product and perfect for a number of professional applications.

But why does it last so long? And are there any downsides such as being non-biodegradable? As a manufacturer offering fiberglass products, our customers often ask these important questions.

In this article, we’ll take a look at why you should use fiberglass, whether fiberglass is biodegradable, ways to make it decompose faster, and how you can make your fiberglass products last longer.

What Is Fiberglass, And How Is It Used?

Fiberglass production involves very fine glass fibers bound together using a polyester resin.

Both the manufacturing process and recycling process of fiberglass are not as energy intensive as other materials like aluminum and produce much less carbon dioxide.

With unique properties such as high tensile strength, fiberglass is used in a variety of products, including planters, insulation, boats, and cars. Because of its durable nature and sleek design, fiberglass is a very popular product and a more natural choice than other plastics and metals.

Fiberglass is made by spinning molten glass into very fine fibers. These fibers are then woven together in the production process to form a fabric that has many uses.

We use fiberglass in our plant pot manufacturing process with a number of other environmentally friendly materials such as natural resin to create a planter collection renowned for its durability, professional appearance, and high performance in both commercial and residential applications.

For these reasons, fiberglass is also used for:

1. Boats

Fiberglass is a popular material for boat hulls because it is strong and durable, yet lightweight. Fiberglass boats are resistant to fire and chemicals, making them a good choice for use in saltwater environments.

2. Cars

Fiberglass is often used in the construction of car bodies because it is lightweight and strong. It is also resistant to fire and chemicals, making it a good choice for use in racing environments.

3. Insulation

Fiberglass is often used as insulation material in homes and businesses because it is an excellent conductor of heat. Fiberglass insulation is also resistant to fire and chemicals, making it a good choice for use in many different environments.

4. Roofing

Fiberglass is a popular material for roofing because it is strong and durable, yet lightweight. It is also resistant to fire and chemicals, making it a good choice for use in many different environments.

5. Other construction materials:

Companies manufacture fiberglass for use in construction materials for pipes, gutters, and ceiling tiles. It is also sometimes used as a building material and in the production of glass fiber optics.

Is Fiberglass Biodegradable?

Yes, fiberglass is biodegradable and can be 100% recycled. Many industries generally accept fiberglass as a sustainable material due to its durability, recyclability, and biodegradability.

Fiberglass is a sustainable material, especially when compared with other materials like plastic, as it can last for decades without needing to be replaced.

Because it has a long lifespan, is durable, energy efficient, and is made from recycled materials, fiberglass is an environmentally friendly choice for construction and other applications.

However, the recycling and reuse of fiberglass is often the most sustainable option. This keeps the material in use for longer and reduces the need for new glass fibers to be produced.

Fiberglass can take up to 50 years to decompose, making it a great long-lasting product. However, the rate of decomposition depends on a number of factors including:

1. The type of fiberglass

Different types of fiberglass will decompose at different rates. The larger and thicker the fiberglass, the longer it takes to decompose. Lightweight fiberglass will decompose faster than heavier fiberglass.

Learn more about the fiberglass materials and resins we use in all our planter products.

2. Environmental conditions

Harsher climates will expose fiberglass to the elements and reduce its lifespan. If your fiberglass product is stored indoors or in a dryer environment, however, it will last longer.

Discover how we ensure our planters are great for outdoor use.

3. Maintenance and upkeep

Although fiberglass is low-maintenance, it’s still important to upkeep your planter. If neglected, your fiberglass product will not last as long as it could.

When you are finished using your fiberglass product, it is important to recycle and dispose of it in a safe and sustainable way. Fortunately, there are many ways to do this, so let’s take a look at them now!

Is Fiberglass Sustainable?

In the face of a growing climate crisis, sustainability is growing in importance. The good news is many industries generally accept fiberglass to be a sustainable material because of 3 main reasons: materials, production process, and its durability.

Although plastic polymers are used in the fiberglass production process, the main raw material used is silica (sand). Abundant and non-depleting, mining silica is far less energy intensive than processing other materials like metals and concrete, or crude oil to make plastic.

Production process

Fiberglass has an extremely low thermal expansion, so it has lower indoor energy consumption than other materials. This means that during the production process, less energy is required. Overall, the net result is fewer greenhouse emissions. Fiberglass requires less than 50% and 30% of the energy used to make concrete and steel, respectively.


Fiberglass is designed for long-term use, and it lasts for decades without needing to be replaced. Its long lifespan makes it a great investment that continues to provide value – the same can’t be said about cheap plastic planters and other products.

How To Dispose Of Fiberglass In A Safe And Sustainable Way

Here are some of the best sustainable solutions to dispose of fiberglass planters!

1. Recycling, reusing and repurposing

  • You may recycle fiberglass into new products so you can give it new life. Recycled fiberglass is environmentally friendly.
  • Reusing fiberglass in other applications can also be helpful in reducing waste.
  • Finally, repurposing fiberglass for other uses can provide a durable and sustainable solution for disposing of the material.

2. Composting

The high temperatures generated by the composting process helps to break down the glass fibers. Though the environmental impact of decomposing fiberglass is low and doesn’t affect human health, it is important to note that fiberglass must be properly disposed of in a commercial composting facility in order for this method to be effective.

3. Thermal degradation

This process uses high temperatures to break down the glass fibers into smaller pieces. Thermal degradation can be done in a specially designed furnace or kiln. Once the fiberglass has been broken down, it can be disposed of in a variety of ways. It can be recycled, used as fill material, or even used to make new products and doesn’t add to greenhouse emissions.

4. Decomposition through micro-organisms

This process is often used in industrial composting facilities, where fiberglass is mixed with other organic waste and then broken down by microorganisms. The end product is nutrient-rich compost that can be used to improve soil quality.

Fiberglass can also be decomposed through the action of microorganisms. This process is typically slower than composting, but it is still an effective method for breaking down this material.

These methods help to reduce the amount of waste that is produced and sent to landfills or incinerators. To learn more about recycling fiberglass, please contact your local recycling center.
