Guide to Types of Biodegradable Floral Foam

In response to growing environmental concerns, biodegradable floral foams have emerged as eco-friendly alternatives to traditional floral foam. These new products are designed to break down more easily in composting or landfill conditions, reducing the impact on the environment. This florist guide explores the various types of biodegradable floral foam available, their benefits, limitations, and best uses.

What is Biodegradable Floral Foam?

Biodegradable floral foam is a plant-friendly alternative to conventional floral foam. While traditional foam is made from non-biodegradable plastic that breaks down into harmful microplastics, biodegradable versions decompose into organic matter under certain conditions.

These foams are suitable for florists looking to reduce their carbon footprint while maintaining the convenience of a stable base for floral arrangements.

Key Features of Biodegradable Floral Foam

• Compostable Components: Many are designed to break down into compostable material within a specific timeframe.

• Water Absorbent: Retains water to keep flowers hydrated.

• Structural Integrity: Offers support similar to traditional foam for arranging stems.

• Environmentally Friendly: Reduces long-term environmental impact.
