How do I donate hair, fur, wool, fleece and other fibers?

Clean Wave donations (even one-time hair donations) are all made through The Hum Sum.

We get a lot of wonderful fiber, and our cottage-industry mini-factories have limited space. We match donations with the nearest addresses and emergency spill needs.

Loose hair must be 1 inch (~3 cm) or longer, natural and unbraided. We are unable to accept wigs or synthetic extensions

Please see our short VIDEO for instructions on how to send hair.

We also always need ponytails that are 4 inches (10cm) or longer, separated from short hair (these are for scrims – the lacy frameworks we fill in with shorter hair, fur, fleece, etc.).

All fiber must be debris free – no garbage, (pins, rocks, rubber bands, extension tips, cigarette butts, foil, food… ) Just pure hair, fur, wool, fleece… If we see trash we have to throw away the whole box because it breaks the felting needles.

This VIDEO shows the steps for posting a GIFT of fiber on

1) Create an account if you don’t have one. It takes 30 seconds, and we do not spam or share our database.
2) Take a photo of your GIFT.
3) Log in so we know your city, etc.
4) Click on the + (on desktop: sidebar bottom left; on mobile: bottom center)
5) Select Donate a Gift -> Clean Wave / hair for oil spills -> type of fiber…
6) Fill out our form and click Publish.

Check your email and nearby hubs will contact you, usually within 72 hours, to accept your gift of fiber.

Thank you!

What is an Eco-Commitment?

Do you ride the bus, walk to work, recycle, garden, shop for secondhand clothes or sell antiques? Plan to install solar, drive a hybrid car or develop a green-job training policy?

Post guestimates for how much money and time your household, your business, your classroom, your nonprofit, your city department… plans to spend on environmental choices.

Add your hours / expenses, and watch the tallies grow on our map, which allows us to quantify the collective impact we are having locally and globally.

What are Eco Events?

Our local-to-global Eco-Events Calendar conveniently consolidates information for coordinators and attendees and showcases inspiring examples for building healthy environments. From climate summits to green-building open-house walking tours, celebrate eco-actions, great and small. Promote your restaurant’s climate-friendly menu, nonprofit’s volunteer day, school’s edible garden show, airport’s new recycling center, local shop’s sale on sustainable products, dog park’s model poo composting station, electric car parade, clean water art expo, bike-friendly neighborhood roundtable… Let’s gather momentum and build on each other’s ideas.

What are the Forums?

This is where we can get some real work done!

Let’s connect and discuss – peer to peer, boots on the ground, around the world, sector by sector – how to tackle pollution, green job creation, sanitation, composting, recycled material stockpiles, renewable resources, protecting old growth forests, over-fishing, affordable housing, climate refugees…

The challenges we face are complex, but we can solve them together. Our forum is a place where eco-enthusiasts can stay connected, get organized, and be heard.

What is FMV and Weight?

Fair Market Value (FMV) is generally considered the price for an item or material.

Please note: Your tax-deductible receipt may show an average, default FMV, but you are solely responsible for the depreciated amount of your donation, which you will deduct on your tax return.

How do I donate food?

Food donation instructions coming.

How do I donate compost?

Compost donation instructions coming.

Safety Tips

Personal Safety

Most people you meet online are worthy of your trust, but there is no denying that the digital world can be dangerous, especially when your online interactions lead to in-person exchanges. offers a platform for people to give or receive items that might otherwise end up in the waste stream. We anticipate that the vast majority of exchanges will be uneventful, but we also encourage users to exercise caution when giving or receiving items through our site. 

To avoid becoming a victim of a crime, please exercise caution when meeting another user from to pick up or drop off an item. When meeting another user from our site for the first time, please make sure that you: 

  • Meet, whenever possible, in a busy public place like a parking lot, coffee shop, a grocery store, or a shopping center. Don’t ever meet in a secluded area
  • Never invite a stranger into your home to look at an item. If you have to give a stranger your home address because the item is too large to carry to a public place, at least try to bring the item outside your front door before the user comes over
  • Before you meet with someone, tell a friend or family member where you are going
  • Bring your cell phone with you when you meet a user
  • Consider bringing a friend or a family member with you when you meet a user
  • Trust your instincts. If something seems off about someone you meet from our site, walk away 

Using is a wonderful way to keep reusable items out of the waste stream, but you should never put your personal safety at risk while giving or receiving an item listed on our site. Take sensible precautions each time you meet a user in person.

Why Has My Match Request Been Cancelled?

There are many reasons why matches may not get completed. Moving dates, breakage, picked-up by someone else, received from someone else… There are always more gifts and more wishes. Please remember that flow and keeping useful items out of the waste stream is very important. Thank you for being part of The Hum Sum- Humanity Adding Solutions!
