Sustainability is no longer a niche ambition or a marketing angle – it has become a responsibility shared by growers, designers, and suppliers alike. Developed by Agra-Wool International, Sideau® sets a new benchmark for sustainable floral design. Not as a compromise, but as a fully functional, professional base that aligns with modern floristry.

Why Traditional Floral Foam No Longer Fits

For decades, floral foam has been the base of countless arrangements. Its downsides, however, are hard to ignore. Conventional foam is oil-based, non-biodegradable, and breaks down into microplastics that persist in soil and water systems long after use. Disposal offers no real solution - it simply shifts the problem elsewhere. As the sector moves toward more responsible practices, the need for a true alternative has become urgent. Sideau® answers that call.

100% Natural, Purposefully Developed

Sideau® blocks are made entirely from natural raw materials, with basalt- a volcanic rock - as their core material. There are no plastics, no petroleum-based components, and no hidden synthetics. After use, the material gradually breaks down into basalt meal, a mineral already present in healthy soils.

But innovation doesn’t stop at the choice of material. Sideau® was developed with direct input from floral professionals, ensuring the product works not only on paper but also at the design table. Every detail reflects practical experience: from handling and cutting to water behavior and stem support. This is sustainability designed for real-world use.

Precision Water Uptake: One Second Matters

One of Sideau®'s most striking characteristics is its water absorption. Only 1 second of submersion is enough to fully saturate the block.

 

 

That brief moment is essential. Sideau® absorbs water quickly, achieving an optimal internal balance almost instantly. Leaving the block submerged longer increases internal water pressure, which affects performance.

Stability Without Sacrificing Creativity

When used as intended, Sideau® delivers on the essentials professionals expect:

Whether used in bridal work, sympathy pieces, or expressive installations, Sideau® supports the design without influencing the style. It stays in the background - exactly where good mechanics belong.

No Waste by Design

Sideau® takes circular thinking seriously. Leftovers, off-cuts, and used blocks don’t become waste - they become a resource.

The material can be reused as a growing resource, replacing traditional potting soil. Small fragments serve as suitable substrates for plants; roots can grow in them. This transforms every remaining piece into part of a new lifecycle, eliminating waste entirely.

For a florist aiming to reduce their footprint without adding complexity, this is a practical advantage that fits seamlessly into daily workflows.

Trusted by the Trade, Ready for the Future

Early users - florists and designers already working with Sideau® - highlight the balance between sustainability and performance. Water control, stability, and handling meet professional standards, while compostability and natural composition answer growing environmental concerns. Certifications and material transparency further reinforce its credibility as a future-ready solution.

FAQ

For who is Sideau®?

Sideau® is perfectly suited for florists and flower arrangers who want to use a fully environmentally friendly base for their creations. Sideau® has the same use characteristics as floral foam. In contrast to floral foam, which is made from oil derivatives and phenol resin, which is plastic, Sideau® is fully biodegradable and made of Earthwool®, a natural product made from basalt, a volcanic igneous rock.

How fast does Sideau absorb water?

A standard Sideau block can absorb approximately 1.5 liters of water in just 1 second. It’s important not to submerge it longer than that, as over-soaking can cause surface softening. Correct hydration ensures optimal stem support and consistent performance.

 

What is the consists of Sideau®?

It consists of 97% basalt, a natural volcanic stone, bonded with a plant-based binder derived from sucrose (natural sugar). This means Sideau® is entirely natural and can be composted after use. The minerals in basalt enrich the soil, promoting healthy plant growth. Additionally, Sideau® is pH-neutral and free from harmful chemicals, making it suitable for use in natural cemeteries and recognized as a sustainable solution in many countries.
