GAiA

Safer and greener
face masks

An Italian research project creating antimicrobial and compostable filters to reduce waste and infection risks.

Durable defense
Longer-lasting protection
GAiA filters aim to block viruses and bacteria and reduce their survival over time, making face masks safer for extended use.

Zero waste
Less plastic, less waste
The materials are designed to be compostable, so the filter can return to the environment at end-of-life without becoming hazardous waste.

What makes GAiA different

GAiA is not simply studying a new mask layer. Bringing together advanced materials engineering and biological validation, the project develops ultra-thin nonwoven fibres where filtration, antimicrobial action, user safety and environmental responsibility are designed together from the start.

Why GAiA?

The problem in facts

Millions of face masks used every day

The pandemic showed how high the demand for respiratory protective equipment can be.

Face masks are hard-to-dispose plastic

Many masks are made of non-biodegradable plastic and are often incinerated, releasing pollutants into the environment.

Risk of contamination

Used masks can retain microorganisms and become a potential infection source if not properly handled.

GAiA in practice

From Lab to face masks of the future

1

Design new filter

We develop fibrous materials using a process called electrospinning, with water-based polymer solutions.

2

Add antimicrobial particles

Tiny “bioglass” particles embedded in the fibres release ions with antimicrobial effects.

3

Test safety and performance

Filters are tested against bacteria and viruses and evaluated for user safety.

4

Assess environmental impact

We analyse the entire life cycle to reduce the environmental footprint.

Traditional filters mainly act as physical barriers. GAiA adds antimicrobial bioglass particles inside the fibre network, so the material is designed to help reduce the survival of microorganisms captured by the filter.

The project uses water-soluble polymer systems and avoids toxic solvents in the production of electrospun fibres, making the development route more compatible with sustainable manufacturing.

GAiA studies the environmental footprint of materials and processes through Life Cycle Assessment, helping identify the most relevant impacts and future improvement opportunities.
