Recycled Acetate Explained — How Singularidad Sunglasses Are Made

When you slip on a pair of Singularidad sunglasses, you're holding something that took 40 hand-finishing steps and weeks of artisanal work to make — in a solar-powered atelier in northern Italy. The material at the heart of it all? Recycled acetate.

But what is acetate, really? And what does "recycled" mean in eyewear? Here's the story.

What is acetate?

Acetate — also called cellulose acetate — is a plant-based plastic. Unlike petroleum-based plastics, acetate is made from natural cellulose fibres extracted from cotton linters (the fluffy fibres that surround cotton seeds) or wood pulp. These cellulose fibres are combined with acetic acid and a small percentage of plasticizers to create a stable, mouldable material with the warmth of natural fibres and the strength of plastic.

It's been the gold standard of premium eyewear for nearly a century. Luxury houses use acetate for one reason: it has a depth of colour and a hand-feel that injection-moulded plastic cannot replicate. Each sheet is layered, pressed, and cured. Each pair of frames is cut from a unique part of that sheet — meaning no two pairs are visually identical, even within the same style.

What makes acetate "recycled"?

Traditional acetate manufacturing wastes a lot of material. When frames are cut from a sheet, the offcuts — the bits between the silhouettes — are usually scrapped. Recycled acetate changes that. The offcuts are collected, ground down, melted, and re-formed into new acetate sheets, which then go on to become new frames.

This isn't recycled in the consumer sense (used frames being broken down and remade). It's industrial recycling: closing the loop on production waste, which is the largest source of waste in the eyewear industry. The result is a material that's chemically identical to virgin acetate, with significantly less raw material consumed.

Some manufacturers — including ours — also use bio-based acetate, where the plasticizers are derived from plant oils rather than fossil-fuel sources. Combined with recycled acetate, the carbon footprint of a single pair drops dramatically.

Why our atelier matters

Singularidad isn't manufactured in one of the giant eyewear factories you might expect. Our partner atelier sits in a small Italian town near the foot of the Dolomites, where eyewear has been hand-finished for generations. The entire facility runs on solar power, with surplus energy sold back to the grid.

Each frame goes through 40 hand-finishing steps — from rough-cut sheet to polished frame:

  • Cutting from sheet on CNC, then re-cut by hand for sharpness
  • Hand-bevelling the inside surfaces for comfort against the temple
  • Tumbling in natural pumice for 48 hours to round edges
  • Hand-polishing with cotton wheels for the deep mirror finish
  • Hand-fitting hinges (the only metal in the frame)
  • Final hand-quality-check by a single artisan

This is the slowest possible way to make sunglasses. It's also why our pairs feel different on your face — substantial without being heavy, smooth where they touch skin.

The semicolon

Look at the inside of the right temple on any pair of Singularidad and you'll find a tiny semicolon etched into the acetate.

The semicolon is a writer's choice. It means: the sentence isn't over. The story continues.

We chose it as a quiet reminder — to ourselves and to whoever wears these — that we're not at the end of anything. Not the end of an outfit. Not the end of a wardrobe. Not the end of our personal story. Whatever just happened, whatever you're moving through — your sentence isn't over.

Two colours, two moods

Singularidad Black — the everyday classic. Deep, glossy, anonymous in the best way. The acetate sheet for the black frames includes a faint marbling that catches light differently at different angles.

Singularidad Burgundy — for the days you want to be looked at twice. A red-brown so deep it reads black at distance and burgundy up close. Pairs especially well with the Transformer Burgundy Leather Coat for full impact.

Both are unisex. Both are limited drops.

Care

Acetate is gentle. Clean with a soft microfiber cloth and lukewarm water with mild soap if needed. Avoid leaving frames in a hot car (extended heat softens acetate). Store in the provided case when not worn. Hinges can be tightened or loosened at any optician's bench — that's part of the design.

A well-cared-for pair of acetate sunglasses lasts for decades. We've seen vintage acetate from the 1950s in better condition than mass-market plastic from last year. That's the longevity argument.

Worth it?

Recycled acetate frames cost more than mass-market plastic. They take longer to produce. The atelier output is small. We can't make these by the thousands.

But you're not buying a pair of sunglasses. You're buying a piece of slow craft, made from a material that pulls less from the earth, in a facility powered by the sun, by hands that have been making eyewear longer than you've been alive.

Singularidad is sized one-pair-at-a-time. When this drop is gone, the next one is months out.
