Head to head
Menstrual cup vs tampons
One is medical-grade silicone you reuse for years. The other is plastic-containing single-use, roughly 11,000 times a lifetime.
Over a menstruating lifetime a person uses on the order of 5,000 to 15,000 disposable period products, most containing plastic: tampon applicators and strings, and pads that can be up to 90% plastic by weight. That is a large volume of single-use plastic in the most intimate contact possible.
A menstrual cup or disc replaces almost all of it with one reusable piece of medical-grade silicone that lasts up to ten years. There is a short learning curve, and it is genuinely worth reading the product notes on fit, but for cost, waste and plastic contact it is not close.
| Tampons and padsSingle-use, plastic-containing | Menstrual cup or discReusable silicone, up to 10 years | |
|---|---|---|
| Plastic content | Applicators, strings and pad layers are plastic | Medical-grade silicone, no plastic |
| Reuse | Single use, then binned | Reused for up to 10 years |
| Wear time before changing | 4-8 hours | Up to 12 hours |
| Cost per year | Recurring, every cycle | One purchase amortised over years |
| Waste | Thousands of items over a lifetime | One cup, occasionally replaced |
| Learning curve | None | A cycle or two to get insertion and fit right |
The verdict
For plastic, cost and waste the cup or disc wins clearly, and most people who push through the first cycle or two do not go back. Keep organic-cotton pads or period underwear as plastic-free backup for the very start, and choose between a cup and a disc on fit: discs sit higher and many find them less noticeable.
The plastic-free picks
Common questions
- Are menstrual cups safe?
- Cups are medical-grade silicone with decades of use behind them. Follow the cleaning and sterilising routine on the product page, and a single cup lasts up to ten years. Toxic shock is rare and the same basic precautions apply as with tampons.
- Cup or disc: what is the difference?
- A cup sits lower and seals against the vaginal walls; a disc sits higher behind the pubic bone. Many people find discs less noticeable and usable during sex. Fit is personal, so it is worth reading both product pages.
- How much plastic is in a tampon or pad?
- Tampons commonly have plastic applicators and strings, and studies put conventional pads as high as 90% plastic by weight across the top sheet, core and backing. Over a lifetime that is thousands of single-use plastic items a cup can replace.
