What to know about Environmental Sustainability

Researchers at Griffith University have conducted an experiment using atmospheric plasma to extend the freshness of cut roses, gerberas, and dahlias. The study suggests that this chemical-free method can maintain flower integrity for up to two weeks, offering a potentially more sustainable alternative to traditional preservatives.

What happened

Plasma treatment keeps cut flowers fresher for two weeks without chemicals Gaby Clark Scientific Editor Andrew Zinin Lead Editor From long‑distance transport to chemical preservatives, most cut flowers come with a hidden environmental cost—something a new…

Why it matters

Griffith researchers used atmospheric plasma to extend the life of cut flowers, building on existing work in agriculture, seed treatment and food preservation.

Common ground

The team used three sets of flowers—roses, gerberas and dahlias—and separated them into five different test groups, ranging from no treatment to full treatment with atmospheric plasma, and monitored them over a two-week period.
