Did you know that a woman uses an average of 11,000 disposable period products in her lifetime? Every year, 45 billion tampons and pads end up in landfills or the oceans, where they can take up to 500 years to decompose. And that’s without even mentioning their often questionable composition: plastics, pesticides, endocrine disruptors…


Fortunately, there’s a healthy, budget-friendly and eco-conscious alternative: period underwear. At Louloucup, we’ve reinvented intimate protection to make it 100% reusable, toxin-free and planet-friendly. In this article, we explain why and how period panties are the zero-waste solution for your period!


So between greenwashing and genuine efforts for the planet, how can you really know what the environmental benefits of menstrual panties are? Is your favorite period underwear brand truly eco-friendly? In what way is absorbent underwear better for the planet and nature than a tampon?

Today, we’re chatting about ecology, plastic, the planet and recycling. Something that concerns every one of us!

🌿 The ecological benefits of period panties

Faced with the plastic continent (the vortex of waste floating in the North Pacific Ocean), our overflowing bins, and the pollution from microplastics in our air, our water (and even our clouds), every action (even the smallest) counts! 


The ecological transition happens in our daily lives when we buy an electric car, choose the train over the plane, etc. These eco-friendly efforts, some more accessible than others, are really important. They can also extend to our intimate lives and, in particular, to our menstrual cycle and period routine by avoiding single-use disposable menstrual products that pollute.  

DID YOU KNOW? 


Every year, 45 billion disposable menstrual products end up in landfills. What if the solution was right here, just a few clicks away? 🙃

What are the environmental benefits of the Jade heavy and very heavy flow period panties?


  • Jade is a period panty that’s perfect for intense and very intense periods. It can absorb the equivalent of 5 tampons!

  • They can be worn for lochia during postpartum, for light urinary leaks or for hemorrhagic periods caused by a copper IUD.

  • Jade is truly amazing because it’s made of 95% GOTS-certified organic cotton. It’s healthy, pesticide-free, ultra-soft and super breathable.

  • The Jade heavy-flow menstrual panty can be found in the teen range, heavy-flow range, plus-size range and postpartum range! Don’t hesitate to add it to your cart with your next order!

Zero waste

  • The Louloucup organic menstrual panty generates no plastic and/or non-recyclable waste. No plastic packaging, no plastic strips, nothing to throw away when you take it off! Menstrual lingerie is durable: you rinse it, wash it and reuse it cycle after cycle, year after year. It’s truly an everyday zero-waste product that we love for its simplicity and practicality (as is often the case with zero-waste products).

  • In this way, menstrual lingerie is the complete opposite of all disposable menstrual products like disposable pads, tampons or panty liners, which can only be used once and must be thrown away after use.

  • Eco-friendly period panties are therefore perfect for anyone wanting to reduce their waste and plastic consumption in particular. Washable, hygienic lingerie is ideal for those who are sensitive to plastic pollution. By choosing durable, reusable items, we pollute less.

  • At Louloucup, our packaging is minimal and mainly made from recyclable materials.

Gentle washing

When we say long-lasting period protection, we mean washable. For optimal care, organic menstrual panties need a gentle wash:

  • a cold-water rinse, 
  • a short machine cycle at max 30°C with an extra-gentle detergent, free from harsh chemicals, 
  • air drying.

In short, you need to follow an eco-friendly washing routine with no overly hot water and no harsh chemicals. This is essential for your eco period panties to keep all their absorbent power. They contain technical fabrics that need special care.

Moreover, for effective care of your reusable menstrual panties, neither the dryer nor the iron is necessary. Simple air drying is best. This way, you save electricity and energy.

“I love it! The (wide) absorbent area comes up high at the back, so you can sleep peacefully in the Jade panties. I can confirm that the panties protect you for 12 hours, for a worry-free night.” Elodie, delighted with the Jade very heavy-flow menstrual panties in organic cotton.

🌿 Why is Louloucup an eco-friendly brand?

Knowing that the textile and fashion industry is one of the most polluting in the world, we at Louloucup wanted to do everything we could to limit our environmental and carbon impact. Several measures have been taken and are applied so that Louloucup’s reusable menstrual products (menstrual cups, period swimsuits and period panties) and all our activities respect our environment and our planet as much as possible.

80% French or European production

Our menstrual cups are made in France. 100% French and local. 80% of our menstrual panties are made in Portugal, a European country renowned for its textile expertise. 

By focusing on local production, we drastically reduce our carbon footprint compared to other brands that produce entirely in China. By choosing Europe over India or China, we also ensure decent working conditions for employees in the workshops. 

Certified organic cotton with GOTS certification

Without a doubt, this is Louloucup’s greatest strength: the inside of all our period panties is lined with GOTS-certified organic cotton. Choosing a natural, organic fabric was a top priority for us.

“Once you know how bad and toxic the composition of tampons and disposable pads is, you have to offer the exact opposite: clean, healthy, traceable, tested and safe menstrual products.”

At Louloucup, the part in contact with your intimate area is made exclusively from organic cotton. A natural material that respects your health and your body, and is also very soft and pleasant to wear. Nothing but positives!

Good to know: using the right materials in our long-lasting period underwear is a top priority for us. We stay completely transparent by clearly listing their composition on every product page. You’ll see that fabrics and materials can vary a lot from one style to another.

All our period panties are regularly tested by independent laboratories that guarantee the non-toxicity of our products. The reports are available online on our website. All our fabrics are guaranteed free from silver nanoparticles, PFAS and pesticides, and are certified Oeko-Tex Standard 100. They are therefore neither harmful to your health nor to the environment. They are free from harmful and toxic substances. 

Road transport rather than air freight

We have chosen road transport rather than air freight to ship our precious eco-friendly menstrual panties from Portugal. Knowing the carbon impact of air freight, road transport, while still polluting, is always a more responsible choice than flying.

Recyclable packaging

If you’ve already ordered from us, you may have noticed that the packaging for our period panties as well as for our menstrual cups is made from recyclable cardboard and paper. This is a given for us. 

Vegan and cruelty-free products

A simple but important reminder that helps preserve our resources and all living beings on our planet: all Louloucup products are vegan and certified cruelty-free. No animal fibers or animal-derived materials are used in the making of our menstrual products.

🌿 In a nutshell. All the environmental benefits of period underwear

Here’s a recap of all the environmental benefits of period underwear:

Reusable and zero waste: one Louloucup period panty can last several years, preventing thousands of plastic and chemical waste items every year.

Mainly European and/or French manufacturing: Louloucup strives to limit its carbon footprint by producing within a 1,200 km radius and choosing partners committed to ethical working conditions.

Safe, certified materials: the menstrual cups are made in France from medical-grade silicone, free from phthalates, bisphenol A, latex and fragrance. The menstrual panties are produced 80% in Portugal, using fabrics certified STANDARD 100 by OEKO-TEX (no harmful substances) and lab-tested to guarantee the absence of PFAS, silver nanoparticles, glyphosate or petroleum derivatives.

Eco-friendly alternative to disposable products: Conventional products (tampons, pads) often contain plastics, pesticides (for cotton) and chemicals, and generate tons of non-recyclable waste every year. Louloucup offers a zero-plastic, zero-pollution solution, with products designed to be washed and reused, significantly reducing environmental impact.

Durability and circular economy: By choosing long-lasting products, Louloucup promotes a circular economic model: less waste, fewer resources consumed, and a reduced carbon footprint from production and transport.

The period panty, or washable period underwear, is an intimate protection for women and teens that offers many advantages: reliability, effectiveness, practicality, comfort, aesthetics, and above all, serious environmental benefits! Thong, high-waisted brief, shorty or string, menstrual lingerie lets you have a much “greener” period than with disposable tampons and pads. That’s undeniable.

1 tampon with applicator = a few hours of use for 800 years to decompose / 1 organic Louloucup period panty = at least 5 years of use, every month!
