It was arguably a sea turtle that launched the plastic-free motion. A 2015 YouTube video of marine biologists pulling a bloody straw out of the nostril of a terrified sea turtle led to requires plastic straw bans, which morphed into proposed bans of all disposable plastic in international locations starting from India and France to Peru and Canada.
But few individuals know that it was a particular sort of plastic that helped save the hawksbill sea turtle from extinction.
Hawksbill sea turtles are graced with a shocking striated shell that, sadly, makes for luxurious jewellery, hairpieces, and glasses. Nine million hawksbill sea turtles have been scooped out of shallow tropical waters world wide between 1844 and 1992. This might need continued if European scientists hadn’t invented a plant-based plastic known as acetate on the flip of the final century. By the Nineteen Fifties, producers have been churning out a tortoiseshell dupe possessing a depth and richness of colour that, together with a world treaty within the late Seventies banning the searching and sale of hawksbills, gave the critically endangered sea turtle an opportunity at survival.
Now you will get acetate earrings and sun shades not simply in traditional tortoiseshell, however in an infinite variety of colours and patterns, starting from black to Caribbean turquoise to clear with a touch of pink.
But as international residents are confronted with photos of plastic spilling out of the center of whales and, sure, sea turtles strangled by plastic, acutely aware customers are taking a second have a look at their plastic sun shades. Some manufacturers like Proof Eyewear have tried switching to sustainably harvested wooden. The South African model Ballo provides in offcuts of African print material sealed with a bio-resin, for a trendy twist. Or you could possibly strive steel frames, like aviators made in Massachusetts by Randolph. Other manufacturers take the recycled plastic route. Sea2See upcycles ocean plastic into frames, and Genusee creates its sun shades out of disposable water bottles mined from the Flint water disaster. Still others like MONC London and Just Human change plastic lenses with glass lenses, which have the additional benefit of being scratch-resistant.
But eyewear manufacturers simply can’t stop acetate — even the sustainable model Shwood now makes use of wooden solely as an ornamental flourish on acetate frames. There’s cotton-based acetate in Proof, whereas Solo and Shwood have acetate, wooden, or bamboo combos.
In truth, a variety of “sustainable” sunglass corporations spend a variety of time crowing about their bamboo after which gloss proper over the acetate half. Nothing to see right here! Look over there! Trees! A charity program!
So, what is that this mysterious acetate? How is it made? And will it biodegrade if it falls off your head into the ocean whilst you’re crusing? I actually had really been confused about these questions for years, however I dug in to lastly get some solutions. What I discovered shocked after which fascinated me.
What Is Acetate and How Is It Made?
Acetate is a cellulosic materials, which makes it an in depth cousin to rayon viscose (which I’ve also done an explainer on—you must think about studying it should you haven’t but after which come again to this). That signifies that it’s a semi-synthetic materials.
Eyewear manufacturers like acetate a lot as a result of in contrast to injection-molded poly-plastics (used for sport and low-cost promo glasses) acetate is hypoallergenic. More importantly, it’s thermoplastic, which suggests your optician can warmth the frames and bend them to completely suit your face. “The glasses really get higher with age,” says Brian Vallario, co-founder of the boutique sun shades model Lowercase, one of many few plucky manufacturers — together with State Optical Co. in Chicago and Kala in California — who’ve made a go of producing acetate frames stateside.
Vallario had invited me to see the sunglasses-making course of at Lowercase’s one-room Brooklyn manufacturing unit, the place staff work alongside machines that carve, warmth, stamp, inject, embellish and polish their high-end frames to perfection. “They could be readjusted, repolished, reworked,” he says. “The colours and patterns that you could obtain with acetate from a pure design perspective are method nicer than injection molding.”
Lowercase glasses doubtless began their life in Tennessee, the place the chemical firm Eastman takes FSC and PEFC-certified sustainably sourced wooden pulp and dissolves it into an acid known as acetyl in a closed-loop course of, producing a fluffy white acetate flake. Some of that powder is shipped to Italy to the well-known family-owned Mazzucchelli manufacturing unit, the place it’s become a transparent goop, dyed, and chopped into pellets, that are hand-mixed to create a sample and baked into acetate blocks, that are purchased by high-end eyewear corporations.
Acetate glasses are chemically intensive to make. There are three acids wanted for this course of: acetic acid, acetic anhydride, and sulfuric acid. Acetic acid (vinegar) and acetic anhydride are reportedly fairly delicate and generally discovered across the house. Sulfuric acid could be harmful at excessive concentrations and when heated. Yes, a typical sheet of acetate is plant-based, however the different 40-ish% is petroleum-derived chemical UV stabilizers and plasticizers, together with the dreaded poisonous phthalates, which have been linked to breast most cancers, bronchial asthma, weight problems, and neurodevelopmental points.
In 2010, in response to those issues, Mazzucchelli launched what they name M49 or bio-plastic, a extra sustainable acetate sheet made with 68% plant-based elements that’s biodegradable. It’s nonetheless a tiny proportion of the general market, however you’ll discover it in eco-friendly sun shades by Stella McCartney.
[embedded content] [embedded content]If the acetate is expressly bio-acetate or manufactured in a regulated atmosphere (for instance, Italy, below the European Union’s strict REACH chemical guidelines), then you definately could be pretty assured that the employees are shielded from hurt.
But in accordance with Vallario, many low-cost eyewear factories in China will minimize prices by sharpening and gluing with acetone, the principle ingredient of nail polish remover, which can cause eye irritation, vomiting, cardiovascular failure and even demise at excessive and lengthy sufficient publicity. Eastman and Mazzucchelli each say they lengthen the well being and security requirements of their house international locations to their factories in China. But whether or not all Chinese staff at different factories obtain ample air flow and protecting gear, no person might inform me. Not a very good signal.
In brief: sure. Acetate sunglass frames can be sustainable and moral if they arrive from a vetted supply, and they’re a better option than virgin plastic. Here’s what to search for:
- Bio-based acetate produced from biodegradable plant sources.
- The acetate is manufactured in Europe after which molded into frames below moral working circumstances, or the corporate has visited the acetate manufacturing facility (not simply the body producer).
- The frames are prime quality and can final a very long time, both to your personal use or in an effort to donate them and they are often reused.
- Bonus: The sun shades are available in sustainable packaging that’s recycled/recyclable.
- Bonus: There’s a giveback component if you purchase a pair.
The most shocking factor I discovered throughout my journey via the eyewear world is {that a} pair of well-made acetate glasses is a sort of gradual style. The most eco-friendly factor you are able to do is spend money on a pair of lovely locally-made, recycled, or bio-acetate frames, maintain them, get them fastened by the model or a neighborhood optometrist in the event that they break, and donate them to somebody in want if you transfer on.
Vallario exhibits me some classic 80s acetate blocks in a striped gray sample. As a tiny firm, Lowercase likes to purchase deadstock acetate blocks from Mazzucchelli that have been sitting round unloved. I watch a robotic arm pluck a rectangle of acetate from a tray, place it inside a lit steel field, and slide closed the door. Another arm deftly carves the block into the tough form of an eyewear body. Vallario subsequent exhibits me the big, old-school picket barrels crammed with wooden chips, the place they tumble the glasses frames for a day to shine them.
“They’re lovely,” says Lowercase’s Vallario, pausing to introduce me to a craftsman who’s hand sharpening a pair that may promote for $350 on the location. “They may cost a little just a little extra, however the price per use over time is far decrease. If you’re shopping for a pair of glasses and you’re keen on them and may reside with them for 2 or three years, then you definately’re decreasing your consumption, and decreasing wasted plastic.”
The sea turtles would approve.
Acetate Sunglasses

You can examine these factories and the manufacturing on their website. They additionally present consciousness and funding to treatment vitamin A deficiencies (which causes blindness) in growing nations.

Stella McCartney sun shades are female and trendy and are made utilizing bio-acetates, that means they’re produced from pure, renewable supplies and are no less than partially biodegradable.
Will Acetate Biodegrade?
There’s additionally not a variety of info on the market on this matter both.
This article is incredibly dense, however appears to be the most effective scientific evaluation obtainable. I’ll prevent the headache and summarize. It says that acetate movies and fibers (very skinny and tiny items of acetate) will biodegrade ultimately, although how lengthy it takes them to degrade relies on the place they’re discarded: within the soil, in water, in an anaerobic atmosphere (a landfill), in sunshine, amongst the best microbes or not. Oh, and including plasticizers might help it degrade quicker. There’s that environmental trade-off situation once more.
A cigarette butt filter made from acetate can apparently take anywhere from 18 months to 10 years to biodegrade. This report says that acetate will degrade, however too slowly to be formally licensed or known as “biodegradable.”
If you drop your sun shades within the ocean, after they do ultimately biodegrade, they are going to leech oil-based poisonous chemical compounds into the atmosphere. When I run my palms via a small bucket of colourful acetate waste pellets within the manufacturing unit and make a joke a few aspect enterprise promoting them to aquarium shops, Vallario says, “I don’t know if I’d need my fish swimming round on this stuff. All the oils from the fabric pull out of it and then you definately get these actually nasty movies within the water.”
Bio-acetate, which is created with out use of petrochemicals, might be higher than plastic, which may take tons of of years to dissolve into the soil or water. But within the meantime, the acetate bits completely can get eaten or choked on by a marine mammal. So they’re not an ideal answer. Just a less-bad one.
Can You Recycle Acetate Sunglasses?
One of the largest environmental points for eyewear is all of the waste. Up to 75% of acetate is usually wasted by an eyewear producer, according to the UK style community Common Objective. Mazzucchelli has began scooping up minimize items and recycling them into black sheets of acetate, and Lowercase offers a few of its waste to native artists. But many of the trade’s waste acetate goes proper to the landfill.
Technically, recycling acetate is feasible. When I used to be in Brussels on the Paradise City festival, a small native nonprofit confirmed me a block of acetate that had been created from recycling outdated cigarette butts — it regarded rather a lot like the fabric in tortoiseshell glasses, really. However, proper now there isn’t any service within the U.S. that may take your outdated frames for recycling.
The Swedish sustainable eyewear model EOE has discovered tips on how to take outdated acetate frames, chop them up into tiny items, and press them into funky patterned blocks of acetate, all of their manufacturing unit within the north of Sweden. Sorry zero-wasters, the one solution to get them your outdated frames is to drop them in a field at a Synsam optometry retailer in Scandinavia. But you possibly can signal as much as be notified when you possibly can pre-order a pair of recycled Regrind glasses.
Otherwise, the most effective factor to do along with your outdated acetate glasses frames is to make use of them for so long as attainable. If the lenses are scratched, you will get them changed via Boomerang. Or should you actually can’t stand them anymore, donate them.

Is your head swimming but? Maybe you want to overlook acetate altogether and go for different choices, comparable to wooden, bamboo, steel, and recycled plastic. And there are many choices!
Metal Sunglasses
You might go for steel sun shades, which I believe are a extra sustainable and long-lasting alternative. (My nice uncle has a pair of steel Ray-bans from WWII. They don’t look nice, however he’s nonetheless sporting them!) The aluminum ones are fully and simply recyclable, whereas the titanium ones are technically recyclable, however can’t go in your metals bin, sadly.

Recycled Plastic
Sunglasses produced from recycled plastic are a better option than virgin plastic, after all. If they fall off into the water, you possibly can consolation your self that the online impact on the quantity of plastic within the atmosphere is near zero.

Wood and Bamboo Sunglasses
I’ve been seduced by the siren name of fully picket and bamboo sun shades a number of occasions, and I can report that many of the fully picket ones break too simply. They’ve damaged on me, with the weak level being the bridge or lens body, they usually’ve damaged on my mates. So I don’t actually advocate them.
But if you’re excited by wooden and bamboo sun shades, listed below are some sustainable choices:
Founded in 2009, Shwood says its wooden comes from “licensed and supervised plantations throughout the globe.” From its unique wooden frames to stabilized seashells and oxidized metals, Shwood has experimented with a number of supplies to craft its pure sun shades. Many of its types now combine wooden and acetate for stronger, extra versatile and long-lasting frames.
