Reduce, reuse, recycle

Discover the beauty in minimizing material goods, repurposing your most well-loved things and intentionally (and sustainably) reducing your carbon footprint.

To eliminate waste, we need to rediscover thrift

There's no such thing as throwing something away, says Andrew Dent -- when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. Dent shares exciting examples of thrift -- the idea of using and reusing what you need so you don't have to purchase anything new -- as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.

Ink made of air pollution

What if we could capture pollution in the air around us and turn it into something useful? Inventor Anirudh Sharma shares how he created AIR-INK, a deep black ink that's made from PM 2.5 pollution. See how he hacked together a clever way to capture these tiny particles -- and make the world just a little bit cleaner in the process.

Creative houses from reclaimed stuff

In this funny and inspiring talk, Dan Phillips tours us through a dozen homes he's built in Texas using recycled and reclaimed materials in wildly creative ways. Brilliant, low-tech design details will refresh your own drive to make more with less.

How I'm making bricks out of ashes and rubble in Gaza

Majd Mashharawi was walking through her war-torn neighborhood in Gaza when an idea flashed in her mind: What if she could take the rubble and transform it into building materials? See how she designed a brick made out of ashes that's helping people rebuild their homes -- and learn about her new project: bringing solar-powered energy to families living in darkness.

When I die, recompose me

What if our bodies could help grow new life after we die, instead of being embalmed and buried or turned to ash? Join Katrina Spade as she discusses "recomposition" -- a system that uses the natural decomposition process to turn our deceased into life-giving soil, honoring both the earth and the departed.

A forgotten Space Age technology could change how we grow food

We're heading for a world population of 10 billion people -- but what will we all eat? Lisa Dyson rediscovered an idea developed by NASA in the 1960s for deep-space travel, and it could be a key to reinventing how we grow food.

Turning trash into toys for learning

At the INK Conference, Arvind Gupta shares simple yet stunning plans for turning trash into seriously entertaining, well-designed toys that kids can build themselves -- while learning basic principles of science and design.

My mushroom burial suit

Here's a powerful provocation from artist Jae Rhim Lee. Can we commit our bodies to a cleaner, greener Earth, even after death? Naturally -- using a special burial suit seeded with pollution-gobbling mushrooms. Yes, this just might be the strangest TEDTalk you'll ever see ...

A circular economy for salt that keeps rivers clean

During the winter of 2018-2019, one million tons of salt were applied to icy roads in the state of Pennsylvania alone. The salt from industrial uses like this often ends up in freshwater rivers, making their water undrinkable and contributing to a growing global crisis. How can we better protect these precious natural resources? Physical organic chemist Tina Arrowood shares a three-step plan to keep salt out of rivers -- and create a circular salt economy that turns industrial byproducts into valuable resources.

The warmth and wisdom of mud buildings

"There are a lot of resources given by nature for free -- all we need is our sensitivity to see them and our creativity to use them," says architect Anna Heringer. Heringer uses low-tech materials like mud and bamboo to create structures from China to Switzerland, Bangladesh and beyond. Visit an awe-inspiring school, an elegant office and cozy social spaces -- all built from natural materials -- in this delightful talk.

Old books reborn as art

What do you do with an outdated encyclopedia in the information age? With X-Acto knives and an eye for a good remix, artist Brian Dettmer makes beautiful, unexpected sculptures that breathe new life into old books.
