Returnable, reusable, or biodegradable wine glass: which one to choose for your parties?
For an eco-friendly evening, the choice of glass matters as much as the choice of wine. Deposit-scheme glass, reusable plastic, stainless steel, biodegradable or compostable: each option has its advantages and limitations. This guide compares them honestly to help you choose according to your context.
Why disposable glass is the worst choice
Disposable transparent plastic wine glasses (the great classic of parties) are a silent ecological disaster. In France, 4 to 5 billion disposable plastic cups and glasses are used every year, of which only a tiny fraction is recycled. The AGEC law (Anti-Waste for a Circular Economy) has prohibited single-use plastics in the catering industry since 2020—but individuals can still buy them for home use, even if it is strongly discouraged.
Disposable plastic glass has no practical advantage that its alternatives do not offer, and its environmental impact is catastrophic. We only mention it to say: move on to something else.
Option 1 — The deposit-scheme glass: the ideal for organized events
The deposit-scheme glass is a real glass (or reusable rigid plastic) rented with a deposit. At the end of the evening, guests return their glass and get their deposit back.
Advantages:
- Zero waste: everything is returned and cleaned.
- The tasting quality is identical to a real glass.
- Suitable for events of 20 people and more.
- Strong eco-friendly impression on guests.
Limitations:
- Requires a local association or rental service that offers this service.
- Logistics management (deposit, return, counting).
- Rental cost to be expected (often €0.20 to €0.50 per glass per day).
Where can you find deposit-scheme glasses? Inquire with your town hall, local social economy associations, or your network of organic caterers. Platforms like Consignity or Écocup networks offer this service in many French cities.
Option 2 — The reusable glass in polypropylene (PP) or Tritan
These are the rigid, transparent plastic glasses that look like real glasses. They are dishwasher-safe and can be used dozens of times.
Advantages:
- Unbreakable — ideal for outdoors, gardens, terraces, pools.
- Dishwasher-safe, so truly reusable.
- Affordable purchase price (starting from €1 to €2 each).
- Available everywhere.
Limitations:
- Tasting is slightly less pleasant than with real glass.
- Wears out after many washes and becomes cloudy.
- At the end of its life, rigid plastic goes in the recycling bin (recyclable PP).
This is the most practical option for house parties where you manage your own tableware. A few dozen PP glasses are enough for all occasions throughout the year.
Option 3 — Stainless steel and metal: no, really not for wine
Stainless steel cups are perfect for hot drinks or beer, but totally unsuitable for wine. Stainless steel slightly alters the aromas, makes it impossible to appreciate the wine's color, and the lack of transparency makes the tasting less pleasant. We mention them only to rule them out: no, stainless steel is not a good solution for serving wine.
Option 4 — Biodegradable or compostable glasses
The market offers single-use glasses made from bio-based materials: corn starch (PLA), sugarcane bagasse, bamboo cellulose... These products are often sold as "compostable" or "biodegradable." But beware of the nuances:
- Compostable ≠ biodegradable everywhere: most PLA glasses are compostable only under industrial conditions (60°C minimum). A garden compost bin is not enough. Thrown into nature, they do not degrade in a few weeks.
- Ordinary trash or recycling center: if you do not have access to industrial composting, these glasses end up in household waste—and their impact is no better than a conventional plastic glass.
- To be prioritized only if industrial composting is available: some municipalities collect biowaste for industrial composting. In this case, compostable glasses are a good option for outdoor events.
The honest conclusion: compostable glasses are a good idea in the right context (festival with an on-site compost stream, municipality with biowaste collection). In other cases, the reusable PP glass remains preferable.
What about real glass?
Let’s not forget: for a home party, real wine glasses remain the most ecological option if you already own them. No waste, maximum tasting quality, unlimited lifespan. The only limitation: the risk of breakage, and the dishwashing logistics when hosting many people.
For a party of 10 to 15 people, a 5L Bag-in-Box served in real glasses remains the most eco-friendly scenario: a single wine container for 10 people, zero bottles, and glasses washed by hand or in the dishwasher.
Summary: which option for which situation?
| Context | Best glass option |
|---|---|
| House party (10-20 people) | Real glasses or reusable PP glasses |
| Garden, terrace, outdoors | Reusable PP glasses (unbreakable) |
| Organized event (30+ people) | Deposit-scheme glasses (rental) |
| Festival / event with compost stream | Compostable glasses (PLA or bagasse) |
| To be avoided in all cases | Disposable transparent plastic glasses |
How to pair this with a Bag-in-Box for a truly eco-friendly evening?
The ideal combination for a committed evening: one or two organic or natural wine Bag-in-Boxes + reusable or deposit-scheme glasses. A 5L Bag-in-Box serves about 33 glasses of 15 cl—enough to cover a full evening with a single container, zero opened bottles, and less than 250 g of waste at the end of the night.

Frequently asked questions about glasses for eco-friendly parties
Are PLA glasses really eco-friendly?
Only if you have access to industrial composting. Otherwise, they end up as household waste and their carbon footprint is similar to a conventional plastic glass. Do not let yourself be seduced solely by "green" packaging.
Where can I rent deposit-scheme glasses near me?
Start by contacting your town hall or the intercommunal authority—many offer a dishware loan service for associations and individuals. Otherwise, search for "deposit-scheme glass" or "Écocup" followed by your city.
Can you serve red wine in reusable PP glasses?
Yes. Polypropylene does not alter the taste of the wine. The only difference compared to a glass is slightly sensory (weight, texture of the rim), but for a relaxed outdoor evening, it is perfectly suitable.
