The Hidden Harm: Why Florist Foam Isn’t as Green as It Looks
Florist foam, that familiar green block used to hold flowers in place has long been a staple in the floral industry. It’s convenient, inexpensive, and helps keep arrangements hydrated and stable. But behind its usefulness lies a serious environmental and health issue that many consumers and even florists are only beginning to understand.
Florist foam, also known as Oasis, is a lightweight, spongy block made from phenol-formaldehyde, a type of plastic derived from petroleum. It’s not biodegradable or recyclable — and yet it's often used once and thrown away.
At Bloom & Brush, we're passionate about beautiful blooms and protecting the environment. We’ve chosen to go foam-free and believe the floral world should move in a more sustainable direction.
Health Risks to Florists and Customers
Chemical Exposure:
Florist foam contains formaldehyde and carbon black, both of which are known to have potential health risks when inhaled over long periods or in large quantities.
Respiratory Irritation:
Cutting and handling dry foam creates fine dust that can irritate the nose, throat, and lungs. Without proper ventilation or protective equipment, this dust can become a regular health hazard in flower shops.
Skin Sensitivity:
Some people experience skin irritation from prolonged contact with the foam — especially when it's wet and breaking down.
Health Risks to Florists and Customers
Florist foam breaks down into tiny microplastic particles that can persist in the environment for hundreds of years. These particles can wash into waterways, harming aquatic life and polluting our ecosystems.
Single-Use Plastic:
Most floral foam is used once and then discarded. Unlike organic materials, it can’t be composted, and it doesn’t break down in landfill.
Toxic Waste:
As it breaks down, florist foam releases toxins that can be harmful to wildlife and contaminate soil and water.
