Hoe duurzaam is menstruatieondergoed vergeleken met maandverband?

Moodies menstruatieondergoed heeft een aanzienlijk lagere milieu-impact dan wegwerpmaandverband, blijkt uit een onafhankelijk Life Cycle Analysis uitgevoerd door Stan Kremers (VU Amsterdam). Eén Moodies broekje vervangt 150 stuks maandverband over zijn levensduur. Daarmee is de CO₂-uitstoot 80% lager, het waterverbruik 76% lager en het afval tot 56 keer minder.

Is menstruatieondergoed van Moodies veilig voor mijn lichaam?

Moodies menstruatieondergoed is gemaakt van OEKO-TEX gecertificeerde stoffen en is 100% vrij van PFAS. PFAS zijn chemische stoffen die in sommige menstruatieonderbroeken zijn aangetroffen en schadelijk kunnen zijn bij langdurig huidcontact. OEKO-TEX-certificering betekent dat de stoffen zijn getest op meer dan 100 schadelijke stoffen. Moodies hanteert deze norm voor de volledige collectie.

Hoeveel afval bespaar ik als ik overstap op menstruatieondergoed?

Moodies-klanten hebben samen al meer dan 407.000 kg aan menstruatieafval bespaard (periode november 2021 – mei 2026). Een gemiddelde vrouw gebruikt jaarlijks zo'n 250 tot 300 wegwerpproducten — goed voor meerdere kilo's restafval per jaar. Eén Moodies broekje vervangt 150 stuks maandverband en gaat 2 à 3 jaar mee.

Waarom kiest Moodies voor bamboe in plaats van katoen?

Moodies gebruikt bamboe omdat de productie ervan minder water verbruikt en minder pesticiden vereist dan de teelt van katoen. Bamboe heeft van nature rondere vezels, waardoor het zachter aanvoelt en vocht beter absorbeert. Uit het VU Amsterdam Life Cycle Analysis blijkt dat het gebruik van bamboe in plaats van katoen een van de grootste factoren is achter het 76% lagere waterverbruik van Moodies broekjes.

Wat is een Life Cycle Analysis en wat zegt die over Moodies?

Een Life Cycle Analysis (LCA) brengt de totale milieu-impact van een product in kaart, van grondstoffenwinning tot afdanking. Moodies heeft een onafhankelijke LCA laten uitvoeren door Stan Kremers, afstudeeronderzoeker aan de VU Amsterdam (opleiding Science, Business and Innovation). De uitkomst: Moodies bamboe menstruatieondergoed stoot 80% minder CO₂ uit, gebruikt 85% minder fossiele brandstoffen, 76% minder water en 76% minder landgebruik dan wegwerpmaandverband. De humane toxiciteit is 65% lager.

Is menstruatieondergoed ook goedkoper dan tampons en maandverband?

Moodies menstruatieondergoed kost op de lange termijn minder dan wegwerpproducten. Gemiddeld geeft een vrouw zo'n €12 per maand uit aan tampons of maandverband, dat is ruim €140 per jaar. Vijf Moodies broekjes zijn genoeg voor een volledige menstruatiecyclus en gaan 2 à 3 jaar mee. In die periode bespaar je €150 tot €200 ten opzichte van wegwerpproducten.

sustainability and comfort in one solution

We have chosen bamboo instead of cotton for some of our panties. Bamboo has rounder fibers which makes it feel softer than cotton and bamboo can absorb moisture more easily, which makes it feel drier. That is nice.

Bamboo production also requires less water and uses fewer pesticides than cotton production. This also makes the planet a little happier.

We are continuously working on improving our products, both in terms of material, model and functionality.

how much does moodies save?

We have calculated how much waste, water, and disposable products you have saved by purchasing Moodies period underwear. We also calculated how many pairs of underwear we have donated to people who desperately need them.

These figures show the impact we are making together. We will update the figures every quarter so that we can continue to monitor and share our progress.

Period: 12/11/2021 - 31/05/2026

*When calculating the saved cubic meters of water, we made an assumption regarding the water savings associated with the nylon pants. Sales of our bundles are not included.

scientifically proven

Moodies commissioned the VU Amsterdam to independently investigate the environmental impact of period underwear — and the outcome is clear.

Stan Kremers (VU Amsterdam, Science, Business and Innovation) conducted a Life Cycle Analysis on Moodies bamboo briefs, compared to disposable pads. The results:

80% less CO₂ emissions
85% less fossil fuels
76% less water consumption
76% less land use
65% lower human toxicity

These figures are calculated over the annual use of period underwear compared to sanitary pads. The study shows that 150 disposable products are equivalent to 1 pair of period underwear.

your period without waste

An average woman uses approximately 60 to 90 kg of tampons and sanitary pads in her lifetime, which amounts to about 250 to 300 disposable products annually. This creates a large amount of waste, because:

Sanitary pads consist of approximately 90% plastic
Tampons contain approximately 6% plastic
Nature needs more than 500 years to break down these products

Period underwear structurally solves this problem. One pair of Moodies underwear lasts 2 to 3 years and replaces 150 disposable products.

Besides period underwear, there are also other sustainable alternatives, such as a menstrual cup, reusable sanitary pads, or reusable tampons. Which choice is best depends on your needs and flow. Moodies offers period underwear in every absorbency level, so you always have a suitable option.

For a cleaner future, the biggest gains can be made with young girls who are developing their first menstrual routines. They are not yet accustomed to disposable products and are therefore more likely to switch.

Menstrual underwear offers girls concrete benefits:

Up to 8 hours of wear without changing or leaking
No hassle with bringing tampons or pads to school
Comfortable during sports - barely distinguishable from regular underwear
Less waste - good for the planet and for their self-esteem

Sustainable materials and packaging

All Moodies panties are made from OEKO-TEX certified fabric and are 100% PFAS-free.

What does that mean in concrete terms?

OEKO-TEX certified - the fabric has been tested for over 100 harmful substances, including heavy metals, pesticides and allergens
PFAS-free - no use of chemicals that have been found in some period underwear and can be harmful with prolonged skin contact
Recycled materials - a large part of our nylon products are made from recycled nylon

Our packaging is also consciously chosen:

FSC-certified materials - sourced from responsibly managed forests
Recycled cardboard - incorporated into the packaging where possible
No unnecessary plastic - we keep the packaging as simple and light as possible

We are continuously working to further improve both our products and packaging, in terms of people and the environment.

Moodies period underwear is made of OEKO-TEX certified fabrics and is 100% free of PFAS. PFAS are chemical substances that have been found in some period underwear and can be harmful with prolonged skin contact. OEKO-TEX certification means that the fabrics have been tested for over 100 harmful substances. Moodies applies this standard to its entire collection.

Moodies customers have collectively saved over 407,000 kg of menstrual waste (period November 2021 – May 2026). An average woman uses about 250 to 300 disposable products annually — accounting for several kilograms of residual waste per year. One Moodies panty replaces 150 sanitary pads and lasts for 2 to 3 years.

Moodies uses bamboo because its production consumes less water and requires fewer pesticides than cotton cultivation. Bamboo naturally has rounder fibers, making it feel softer and absorb moisture better. The VU Amsterdam Life Cycle Analysis shows that using bamboo instead of cotton is one of the biggest factors behind Moodies briefs' 76% lower water consumption.

A Life Cycle Analysis (LCA) maps out the total environmental impact of a product, from raw material extraction to disposal. Moodies commissioned an independent LCA from Stan Kremers, a graduate researcher at VU Amsterdam (Science, Business and Innovation program). The result: Moodies bamboo period underwear emits 80% less CO₂, uses 85% less fossil fuels, 76% less water, and 76% less land than disposable sanitary pads. Human toxicity is 65% lower.

Moodies period underwear costs less in the long run than disposable products. On average, a woman spends about €12 per month on tampons or sanitary pads, which is over €140 per year. Five pairs of Moodies are enough for a full menstrual cycle and last 2 to 3 years. During that period, you save €150 to €200 compared to disposable products.

Sustainable Development Goal 12

We contribute to sustainable production and consumption, with more efficient use of raw materials. This reduces the pressure on the environment and reduces dependence on those raw materials.

Sustainable Development Goal 5

The degree of equality is measured, among other things, by the difference in pay for work and position, but also by the labor participation of men and women in business and administration. With our products we ensure improved labor participation of women.
