You’ve probably heard of polyester fabric before: It’s commonly used to make clothes and home furnishings. But what is it and how does it compare to recycled polyester? Which is more sustainable?

Personally, I try to opt for natural fibers whenever I can. Synthetic materials shed microplastics over time, aren’t as durable, and can’t be composted at the end of their life. Plus, I don’t really like how synthetic materials feel on my skin.

However, there are certain items that are harder to find synthetic-free, like athletic-wear and period underwear. These clothing items tend to need synthetics to offer stretchability and enhance performance.

When I first started going zero waste, I wanted to live a completely plastic free lifestyle, even free of recycled plastic. But then I started learning a lot more about recycled plastic materials, emissions and looking at the bigger picture.

Recycling plastic, like recycled polyester, definitely has its place in the sustainability movement. If you’re wondering which is better for the environment, here’s everything you need to know.

what is polyester?

Polyester is a synthetic fabric made from petroleum-based chemicals, specifically polyethylene terephthalate (PET). Petroleum (aka crude oil) is a non-renewable material that is often extracted from the earth unsustainably.

To create virgin polyester, 70 million barrels of oil are used annually, and turning this oil into fabric releases a lot of toxins into the environment.

However, most of our clothes are made of polyester because of how cheap it is to make. If you check a clothing label, chances are it will contain a certain amount of polyester in it.

Polyester is non-biodegradable, meaning it can take hundreds of years to decompose in landfills.

Its widespread use in fast fashion exacerbates the issue, as discarded garments often end up as long-lasting waste. Not so fun fact: We have enough clothes on the planet right now to for the next six generations!

Polyester vs. Recycled Polyester: Which is More Sustainable?

what is recycled polyester?

Recycled polyester, often referred to as rPET, is made by repurposing existing plastic waste, such as used PET bottles or discarded fishing nets. This process reduces the need for virgin raw materials and diverts plastic waste from landfills and oceans.

The production of rPET uses significantly less energy compared to virgin polyester and results in lower greenhouse gas emissions. It’s a step towards a circular economy, where materials are reused rather than discarded.

Kayaness, a sustainable period company I co-founded with Shelby Orme, utilizes recycled polyester. The period underwear is made using ethical manufacturing and undergoes rigorous testing for safety.

Plus, period underwear is reusable and helps keep a lot of single-use period products out of landfills (the average pad contains four plastic bags worth of plastic in it!).

There is so much plastic in the world — we should be turning it into something. In fact, we shouldn’t be using any virgin plastic! After all, the most ecofriendly plastic is the one that already exists.

And plastic is only recycled 5-6% of the time, down from 9%. If we want to see that recycling rate go up, the best thing we can do is support brands that utilize recycled materials.

is recycled polyester a good material?

In comparison to virgin polyester, yes, recycled polyester is a good material.

RPET repurposes plastic waste, such as PET bottles, reducing the need for virgin resources and diverting waste from landfills and oceans.

It requires significantly less energy (59% less to be exact) to produce compared to virgin polyester.

Additionally, rPET retains the durability and versatility of virgin polyester, making it suitable for a wide range of applications.

does recycled polyester release microplastics?

Yes, recycled polyester does release microplastics. Like virgin polyester, it sheds tiny plastic fibers during washing and wear.

These microplastics can enter waterways and contribute to environmental pollution. While rPET reduces the need for new plastic production, addressing the issue of microplastic pollution remains a challenge for both recycled and virgin synthetic fabrics.

can recycled polyester be washed?

Yes, recycled polyester can be washed, and it is generally easy to care for. It can be machine-washed, but it’s recommended to use cold water and a gentle cycle to preserve the fabric’s quality.

For example, Kayaness (made from recycled polyester) can be machine-washed on delicate in cold water with a mild detergent. Just make sure to air dry them!

To minimize microplastic shedding with polyester fabrics, consider using a washing bag designed to capture fibers or washing less frequently. Always check the care label for specific instructions.

is recycled polyester cool in summer?

Recycled polyester is lightweight and moisture-wicking, which can help keep you dry in hot weather.

However, it is less breathable than natural fibers like cotton or linen, which makes it less ideal for staying cool in summer.

It’s a better choice for activewear or situations where moisture wicking is a priority, but for ultimate breathability and comfort, natural fabrics might be preferable.

Polyester vs. Recycled Polyester: Which is More Sustainable?

which is more sustainable?

In terms of polyester vs. recycled polyester, you may be wondering which is more sustainable. Recycled materials are always going to be more sustainable than virgin materials.

Here are the key differences.

environmental impact:

  • Virgin polyester relies on non-renewable fossil fuels and contributes to resource scarcity.
  • Recycled polyester reduces plastic waste and conserves resources, making it a more sustainable option.

energy and water consumption:

  • Producing recycled polyester uses about half the energy required for virgin polyester.
  • The extraction of virgin raw materials and manufacturing them into single use items uses up water. Recycling reduces the need for materials, thus creating a smaller water footprint.

durability and quality:

  • Both materials are durable, but recycled polyester offers comparable performance while being more eco-friendly.

microplastics:

  • Both virgin and recycled polyester shed microplastics during washing, which can pollute waterways. Innovations in fabric technology are needed to address this issue.

Recycled polyester is the more sustainable choice. By repurposing existing materials, it reduces the environmental footprint of production and helps tackle the global plastic waste crisis.

However, it’s not a perfect solution, as it still sheds microplastics and relies on synthetic materials. The most sustainable choice will always be to thrift natural fabrics and materials when possible. Or support sustainable, nontoxic clothing brands.

Outdoor Projects You Can DIY for Almost Nothing

Published

on

It always strikes us as amusing how many DIY projects you see online that seem to require more time and more money than it would take to simply buy the thing they’re trying to DIY in the first place. Are we missing the point?

We think that doing things ourselves and taking back the power to create instead of simply consuming is absolutely vital to the green movement. But if you don’t already have the materials and spend a lot of money purchasing craft supplies, does it really make sense to DIY?

These eight projects are true do-it-yourself masterpieces. One-of-a-kind outdoor projects you can make for almost nothing, with supplies you most likely already have or can easily pick up second hand for a song. Roll up your sleeves and let’s get started!

1. Teapot/Teacup Bird Feeder

Do you have one of Grandma’s old tea sets lying around that doesn’t quite fit into the sleek modern aesthetic you’ve been cultivating? Put it to great use by feeding the birds in your area — in style.

Thrift stores are always awash in old china, so if you don’t already have the old tea set, consider going wild and spending a few bucks for this DIY delight. You’ll find blogger Dinah Wulf’s instructions for the teacup bird feeder at DIY Inspired.

Safety note: Use sturdy twine or cord — not chain — to hang the feeder. Birds can catch their toes in chain links, which causes serious injury. The National Audubon Society also recommends cleaning seed feeders every two weeks (more often in hot, humid weather) by scrubbing with soap and water and soaking in a 50-50 vinegar-water solution to prevent the spread of avian disease.

2. Gardening Tool Storage

What on earth do you do with those rusty-as-heck, old-school garden rakes hanging around your garage? Well, if you’re any sort of DIY genius, you press them into service as a gardening tool holder.

The original inspiration for this project came from Beth Logan at Artstuff Ltd., whose blog has since gone offline. For a current walkthrough, see the Repurposed Rake Tool Rack tutorial at DIY n Crafts (project #14 in their roundup of 25 ways to reuse old garden tools). The concept is embarrassingly simple — remove the rake handle, mount the head tines-out on a fence or garage wall, and use the tines themselves as hooks for trowels, gloves, and pruners — but eye-catching enough to make you look like a DIY pro.

3. Bottle Tree

Do you like wine? No, I mean do you really like wine? Do you want a reason to drink more of it? And does your garden need a cute border? This sustainable, upcycled garden border may be just the project for you. You might have to expand your drinking list to include bottles of various shapes, sizes, and colors — but variety is the spice of life.

When friends ask how you managed to collect so many bottles, just laugh gaily and then distract them with your dainty teacup bird feeder. The bottle tree tradition itself runs deep — Mississippi garden writer Felder Rushing traces the practice back through African American Southern folk art and, by his own research, as far as ancient Egypt and Mesopotamia. See his bottle tree gallery and history for inspiration, or jump straight to his how-to guide for building one out of a cedar snag, rebar, or just about anything else.

4. Colorful Outdoor “Tiles”

If your backyard isn’t perfectly landscaped and manicured, with an impeccably tiled “outdoor living space,” don’t despair. You can use up all those half-empty paint cans and create a Pinterest-worthy colorful backdrop for evenings spent clustered around a fire or barbecue.

Pop a few coats of paint on cement tiles and you have a one-of-a-kind flooring solution. If you rent, the same effect could be achieved on a more temporary basis by letting the kids go wild with sidewalk chalk and create a mosaic masterpiece. Check out Elsie’s Painted Patio Tiles at A Beautiful Mess for the back story on this DIY idea. (Heads up: the original author noted she had to touch up the paint each spring in Missouri winters — a porch and patio floor enamel will hold up better than wall paint.)

5. Home Sweet Gnome

Okay, this one might be the least practical idea of the bunch, but that may be why I love it oh so much. If you have a stump in your backyard and you’re not willing or able to pay the truly insane amount it costs to have it ground down and removed, how about making it into a little gnome home? This is the perfect outdoor project if you have small children in your life.

Construct the trappings of a little house — door, windows, winding garden path — from found objects or natural materials, and affix them to the stump. Bonus points if you don’t tell the kids about this particular DIY project and allow them to simply stumble upon it one day in the garden. My mind would have been blown if I had come across one of these as a seven-year-old. For a step-by-step build, see this Gnome Tree Stump Home tutorial on Instructables.

Safety note: Don’t use an angle grinder to gouge windows or doors into a stump. Use a chisel and mallet for shallow detail work, or attach decorative pieces (driftwood, bark, polymer clay) to the outside instead.

6. Mosaic Stepping Stones from Broken China

Every household eventually accumulates a small graveyard of chipped mugs, a single survivor from a four-piece dinner set, or a beloved teapot with a hairline crack. Rather than tossing them — broken ceramics generally aren’t accepted in curbside recycling — embed them in concrete stepping stones for a garden path that’s genuinely one of a kind.

This pairs beautifully with the teacup project above: any teacups that don’t make it past Project #1 (you will break a few) can come back as paving. The DIY mosaic stepping stones tutorial at Gardening.org walks through the full process — breaking ceramics safely inside a drop cloth, sizing pieces to half-inch to one-inch fragments, pressing them into wet concrete, and sealing the surface so sharp edges don’t cause injury underfoot. Basic mold options include an old cake pan, a plastic plant saucer, or a purpose-built stepping stone form from a craft store.

Safety note: Wear safety glasses and heavy gloves when breaking ceramics. Once cured, run a finger over the surface to check for protruding edges and file or sand any down before placing the stone where bare feet might land.

7. Vertical Pallet Herb Garden

Shipping pallets are one of the world’s most abundant near-free materials. Small businesses, garden centers, and feed stores often have stacks of them out back, and asking politely beats the alternative of seeing them landfilled. Mounted vertically against a sunny wall or fence, a pallet becomes a stacked planter that holds enough herbs to keep a kitchen in basil, thyme, parsley, and chives all season.

Grit Magazine published a clear how-to for a vertical pallet planter — line the back and sides with landscape fabric or heavy plastic to hold soil, fill through the slats, and plant each gap as its own row. The gaps act as natural divisions, so different herbs don’t fight for the same root space.

Safety note: Use only heat-treated pallets for anything edible. Look for the IPPC stamp with the letters HT (heat treated) and avoid any stamped MB (methyl bromide — a fumigant restricted under the Montreal Protocol). Unstamped pallets are unknowns; skip them for food crops. The same heat-treated pallets are fine for ornamental flowers either way.

8. Punched Tin Can Lanterns

Steel food cans — soup, tomato, coffee — are one of the most recyclable materials on Earth, but the recycling-then-buying-something-decorative loop has plenty of slack in it. With nothing more than a hammer, a few nails of varying sizes, and the freezer, an empty can becomes an outdoor lantern that throws constellation patterns across a patio at dusk.

HGTV’s tin can lantern tutorial covers the trick that makes this project work: fill the can with water and freeze it solid before punching, so the ice supports the can wall and prevents denting. Sketch your pattern on paper, tape it to the frozen can, punch through with a nail at each marked dot, and let the ice thaw. Drop in a battery tealight (much safer outdoors than a real flame) and group them along a walkway or down the center of an outdoor table.

The Point of All This

None of these projects requires you to buy more than a tube of waterproof adhesive, a bag of concrete, or maybe a stepping stone mold. The materials — chipped china, leftover wine bottles, empty cans, a forgotten pallet, an old rake — are already in your house or someone else’s. That’s the point. The greenest project is the one that uses what already exists, and the best part is that yours will look like nobody else’s.

Best of Sustainability In Your Ear: Author Nadina Galle on The Nature of Our Cities

Published

on


More than half the world’s population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina’s book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

Nadina Galle, an ecological engineer and author of The Nature of Our Cities, is our guest on .

From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities, is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell’s Books.
