Capillum: Transforming Hair Waste into Eco-Friendly Resources

Capillum is France’s first hair recycling initiative, transforming hair waste into valuable resources. By collecting hair from salons, Capillum promotes sustainability and protects marine environments. With innovative applications, this project highlights the potential of hair as a resource rather than waste, contributing to a cleaner planet and supporting sustainable development goals.

What is Capillum?

Capillum® is the very first hair recycling initiative in France, pioneering a new way to turn hair waste into valuable resources. Every day, around 1 million French people visit hairdressers, producing a staggering 4,000 tons of hair waste annually. Instead of letting this hair end up in household garbage, Capillum steps in to collect it directly from salons or relay points. This project is all about transforming what was once considered waste into something useful and eco-friendly. It’s a fresh take on circular economy principles, aiming to make hair the fiber of tomorrow through innovative and ecological solutions.

Main Benefits of the Capillum Project

Capillum’s impact is impressive and wide-ranging. Here are some key facts and figures that highlight why this project matters:

  • 1 million French people visit hairdressers daily, generating 4,000 tons of hair waste each year.
  • Hair can absorb up to 8 times its weight in hydrocarbons, making it a powerful pollution absorber.
  • Hair contains 95% keratin, a precious natural protein with potential uses in skincare.
  • Collected hair helps clean waters in ports, oceans, and polluted soils.
  • Hair mulch nourishes soil, limits watering and weeding, and is 100% natural and usable in gardens, orchards, and open ground.

How Does Hair Recycling Work?

The process is straightforward but impactful. Hair is collected from salons or designated relay points using a complete recycling and communication kit provided to participating salons. Once gathered, the hair is processed and repurposed into various ecological products. This system not only reduces waste but also raises awareness among salons and customers alike. Plus, salons that participate get listed on an interactive map, encouraging more people to join the movement. It’s a community effort with a clear environmental purpose.

Innovative Applications of Recycled Hair

Hair isn’t just waste—it’s a resource packed with potential. Capillum explores several innovative uses for recycled hair, including:

  • Absorbents for pollution control, especially in water and soil clean-up.
  • Mulching material for agriculture that enriches soil and reduces the need for watering and weeding.
  • Research in medicine and skincare, thanks to the high keratin content.
  • Ongoing innovation projects to discover new applications that benefit the planet.

These applications show how a simple waste product can be transformed into something truly valuable and sustainable.

Why Protect Our Oceans?

One of Capillum’s core missions is to protect marine environments. Hair’s unique ability to absorb hydrocarbons makes it an excellent natural tool for cleaning polluted waters in ports and oceans. By diverting hair from landfills and using it to soak up harmful substances, Capillum helps reduce ocean pollution. This is crucial because healthy oceans support biodiversity, regulate climate, and provide livelihoods for millions. So, every strand of hair collected contributes to a cleaner, healthier planet.

Capillum’s Contribution to Sustainable Development Goals (SDGs)

  • SDG 12: Responsible Consumption and Production – by recycling hair waste and promoting circular economy practices.
  • SDG 14: Life Below Water – through pollution absorption and ocean protection efforts.
  • SDG 15: Life on Land – by improving soil quality and supporting sustainable agriculture.
  • SDG 13: Climate Action – by reducing waste and promoting eco-friendly innovations.

How Can You Get Involved?

Everyone has the power to make a difference. Whether you’re a salon owner or a customer, participating in Capillum’s initiative means turning hair waste into a resource for the future. Salons receive a full recycling and communication kit, making it easy to collect hair and educate clients. Plus, being listed on the interactive map helps spread the word and grow the community. Supporting Capillum means supporting innovation, sustainability, and a cleaner planet. So why not join the movement and help make hair the fiber of tomorrow?

What Capillum actually does

Capillum describes itself as the first hair recycling and recovery sector in France. Hairdressing salons collect their clippings, either at the salon or at a relay point, and Capillum takes them off the waste stream. Member salons receive a recycling and communication kit and are listed on an interactive map on the Capillum site.

The collected hair is turned into new materials. Agricultural mulch is already available to buy and is presented as a way to limit watering and weeding. An oil-spill absorbent and keratin-based technical materials are in development.

Where Capillum shows up

  • Hairdressing salons: a collection route and a kit to divert hair clippings from general waste.
  • Agriculture and gardening: hair-based mulch that reduces watering and weeding.
  • Pollution control: an absorbent for hydrocarbon spills, currently in R&D.

Proof, not just claims

The 4,000 tonnes figure sizes the waste stream Capillum targets. The absorbent and keratin figures are product characteristics Capillum publishes for materials still in development, not delivered volumes.

Why this belongs on a sustainability directory

Hair clippings are normally discarded with general waste. Capillum collects them and turns them into usable materials, which is a direct circular-economy mechanism for SDG 12 (responsible consumption and production). The oil-spill absorbent targets hydrocarbon pollution of water, which links to SDG 14 (life below water), though that product is still in development.

Frequently asked questions

Where is Capillum based, and who uses it?

Capillum is a French company founded in 2019 in Clermont-Ferrand, according to press coverage. Its main users are hairdressing salons that collect clippings, plus gardeners and farmers who use the mulch.

Which SDGs does Capillum support, and how?

SDG 12, by recovering hair waste and turning it into materials such as mulch. SDG 14, through an absorbent for hydrocarbon spills that is still in development.

How is Capillum verified as a sustainability project?

No third-party certification could be verified. The evidence is Capillum’s own published collection model, its product range, and independent French press coverage of its hair recycling activity.
