Expanded polystyrene (EPS) is the most common filling used in modern bean bags — but is it environmentally friendly? As more Australians look to reduce plastic use and shop responsibly, bean bag filling often becomes part of that conversation.
The answer isn’t as simple as yes or no. It depends on how the material is manufactured, used, maintained and ultimately disposed of. Let’s take a closer look at EPS bean bag filling, plant-based alternatives and the real environmental considerations.
What Is Bean Bag Filling?
Most high-quality bean bags use expanded polystyrene (EPS) beads. These lightweight white beads are made by expanding polystyrene with heat, creating air-filled spheres that are approximately 98% air and 2% plastic.
EPS is widely used in packaging, insulation and construction due to its durability, shock absorption and moisture resistance. It is also the standard filling used in many bean bag chairs in Australia because it offers long-lasting support while remaining lightweight.
Alternative fillings include:
- Plant-based bio beads (such as Ingeo-based Envee beans)
- Shredded foam
- Recycled textiles or soft plastics
- Natural materials such as dried beans or cedar shavings
Each has different environmental trade-offs.
How Is EPS Manufactured?
EPS begins as expandable polystyrene — a petroleum-derived plastic containing a safe expansion agent. During production, the material is heated with steam, causing it to expand into lightweight beads filled with air pockets.
The manufacturing process:
- Uses steam (often generated from natural gas)
- Produces minimal solid waste
- Recycles production scraps back into manufacturing
- Consumes relatively low water compared to many other materials
While EPS is derived from fossil fuels, it represents a very small percentage of overall petroleum production. The environmental impact comes primarily from energy use during manufacturing and end-of-life disposal.
Environmental Advantages of EPS Bean Bag Filling
1. Lightweight = Lower Transport Emissions
Because EPS is 98% air, it is extremely lightweight. This reduces transport emissions compared to heavier materials, particularly when shipped in bulk across Australia.
2. Long Lifespan
Quality EPS beads resist compression and maintain structure for years. A durable product that doesn’t require frequent replacement can reduce overall material consumption.
If your bean bag begins to flatten, topping it up is often sufficient. Our guide on how many bags of beans you need explains how to calculate refill quantities.
3. Recyclable Material
EPS is 100% recyclable. In Australia, recycling availability varies by council, but many facilities accept expanded polystyrene through dedicated drop-off programs.
Recycled EPS is often repurposed for:
- Construction insulation
- Packaging materials
- Composite plastic products

4. Energy Recovery Potential
EPS can be safely converted into energy through controlled waste-to-energy systems. When properly managed, this process produces minimal ash and controlled emissions.
Environmental Concerns About EPS
Despite its benefits, EPS does have limitations.
- It is petroleum-based and not biodegradable.
- If improperly disposed of, it can contribute to plastic pollution.
- Recycling infrastructure is inconsistent across regions.
Like many plastics, the environmental impact depends heavily on responsible disposal and recycling behaviour.
Plant-Based Alternatives: Are They Better?
Plant-based options such as Ingeo-derived Envee beans offer a renewable alternative. These beads are made from fermented plant starch (typically corn) rather than petroleum.
Advantages include:
- Reduced greenhouse gas emissions during manufacturing
- Non-toxic composition
- No harmful additives
Some plant-based materials generate up to 80% fewer greenhouse gases during production compared to traditional polystyrene. However, availability and cost can vary.
Other Eco-Friendly Filling Options
Recycled Materials
Repurposing old clothes, shredded foam or soft plastics can reduce landfill waste. While this is practical for DIY projects, it often results in uneven comfort and faster compression.
Natural Fillers
Dried beans, hay or cedar shavings are biodegradable and renewable. However, they can:
- Attract pests
- Break down quickly
- Absorb moisture
- Become heavy over time
These materials are rarely suitable for long-term indoor furniture use.
Lifecycle Thinking: The Bigger Picture
Environmental impact isn’t just about the raw material. A proper lifecycle assessment considers:
- Energy used in manufacturing
- Transport emissions
- Product lifespan
- Recyclability
- Disposal method
A long-lasting bean bag filled with EPS that is responsibly recycled at end-of-life may have a lower total impact than a biodegradable alternative that needs frequent replacement.

So, Is Bean Bag Filling Environmentally Friendly?
The honest answer: it depends on how it’s used and disposed of.
EPS filling can be environmentally responsible when:
- Manufactured to accepted standards
- Used in durable products
- Maintained properly
- Recycled at end-of-life
Plant-based alternatives may reduce manufacturing emissions, but availability, durability and end-of-life processing should also be considered.
No material is completely impact-free. The most sustainable choice is often the one that lasts longest and is responsibly managed at disposal.
Frequently Asked Questions
Is EPS bean bag filling toxic?
High-quality EPS beads are non-toxic and contain no harmful additives when manufactured according to Australian safety standards.
Can bean bag filling be recycled in Australia?
Yes, but availability varies by council. Many areas offer dedicated polystyrene drop-off locations.
Are plant-based beans biodegradable?
Some plant-based alternatives are industrially compostable, but check manufacturer specifications, as conditions may vary.
Bottom Line
Bean bag filling is not inherently harmful — but like any material, its environmental footprint depends on production, longevity and disposal. EPS is lightweight, durable and recyclable, while plant-based options reduce reliance on fossil fuels.
For environmentally conscious buyers, the most responsible approach is choosing high-quality filling, maintaining it properly and ensuring it is recycled at the end of its usable life.
