Microplastics: the shock study of ANSES on glass bottles

A recent study by ANSES reveals that Drinks packaged in glass bottles contain more microplastics that those in plastic, bricks or cans: contents [oaicite: 1] {index = 1}.

📌 Key results

• Soft drinks (cola, beer, lemonade, icy tea) in glass: approximately 100 particles of microplastics per liter, or 5 to 50 times more than in plastic or can: Contentreference [oaicite: 2] {index = 2}.
• For glass bottled with glass: 4.5 particles per liter, against 1.6 particle In plastic bottles or bricks: contents [oaicite: 3] {index = 3}.

🧪 Origin of contamination

The study shows that the particles come mainly from the Metal capsules paint. Micro-stakes on traffic jams, caused by friction, release paint in the form of microplastics: contents [oaicite: 4] {index = 4}.

🔬 Possible reduction of microplastics

Tests have shown that cleaning capsules before traffic jam (blowing + rinse with water/alcohol) reduces the contamination of:

• 287 → 106 particles/l (after blowing)
• → 87 particles/l (after blowing + rinsing): contents [oaicite: 5] {index = 5}

💧Water is the best choice ... even in glass

Only 4.5 particles/L, Glass bottle water remains little contaminated compared to other drinks: Contentreference [Oaicite: 6] {index = 6}.

⚠️ End clap: should we stop the glass?

No: glass remains safe packaging, especially for water. But this study shows thatUnexpected contamination can be avoided Thanks to simple good industrial practices.

💡 Practical advice

• Continue drinking water (limited contamination).
• Vary the containers: plastic, glass, filtered tap water.
• Favor tap water: less CO₂, more economical, without microplastics linked to capsules.
