How many cups does a 500-guest wedding throw away?

Nobody counts the cups at a wedding. So we did the maths for a typical 500-guest function, using simple assumptions you can change for your own event.

A simple count

• Welcome drink on arrival: 1 cup per guest.
• Water through the evening, with cups put down and forgotten: 2–3 cups per guest.
• Tea, coffee or a dessert drink: 1–2 cups per guest.

That’s 4 to 6 cups per guest, or roughly 2,000 to 3,000 cups for one 500-guest function. Most Indian weddings have more than one function, such as a mehendi, sangeet and reception, so the full wedding often uses several times that.

Now multiply by a wedding season

The Confederation of All India Traders estimated 46 lakh weddings in India between 1 November and 14 December 2025, with about ₹6.5 lakh crore of spending. Catering made up 10% of that.[3]

Not every wedding has 500 guests or uses disposable cups. But even at a conservative 300 cups per wedding, 46 lakh weddings would get through about 1.4 billion cups in six weeks. At around 3 g per plastic cup, that’s roughly 4,000 tonnes of plastic.

Where those cups go

Plastic cups and glasses have been banned in India since 1 July 2022. Yet a 2025 field survey found banned single-use plastics still in use at 84% of the sites it checked in four cities.[1][2]

After the event, cups go into mixed waste. They’re light, food-soiled and worth almost nothing to waste pickers, so few are recycled. Most are dumped or burnt.

What caterers and venues can do

• Make steel or glass tumblers standard in the catering package, not an upgrade.
• Count the cups at your next event to get a baseline.
• Wash glasses at the counter, not in a back room, so clean glasses keep up with the queue.
• Put ‘no disposable cups’ in the venue’s booking terms.

GILAS is built for this. It serves water in a steel glass and cleans each returned glass on the spot, with no plumbing, so it can stand right beside a wedding counter.
