Every wellness brand on earth has a sustainability page.
In an industry where roughly 75% of supplement and nutrition packaging is plastic, we chose a different system: plastic-free packaging with very little packaging to begin with.
No plastic bottle. No secondary box. No layers of packaging around more packaging.
Your first order arrives in the mailer itself: a refillable stainless steel canister, our stainless steel Overnighter pendant plated in 24k gold, and your compostable refill packet. That's it.
We use noble materials, like stainless steel and gold, for the things designed to stay. The canister and pendant are permanent objects, chosen for their durability, reusability, and timeless quality.
The things that need replacing are designed differently. Your monthly capsules arrive in a compostable refill packet inside a lightweight recyclable paper mailer.
Permanent where permanence makes sense. Compostable or recyclable where it doesn't.
Our Packaging, at a Glance
- Plastic-free packaging
- No secondary packaging

- Stainless steel Overnighter plated in 24k gold
- Plant-based compostable refill packets, certified to ASTM D6400 for industrial composting, backed by a funded composting pathway, with home compostability certification in progress
- Lightweight recyclable paper refill mailers
- FSC-certified recycled paper shipping box
- Refills designed to replace disposable supplement bottles
Designed to Stay
Some things shouldn't be disposable.
Your starter kit includes a stainless steel canister designed to live on your counter and be refilled month after month. It's built to become part of your daily rhythm rather than something you throw out and reorder.
We chose stainless steel because it's durable, reusable, and timeless. It's a noble material, meant to be cherished rather than replaced.
The same philosophy applies to our Overnighter, the tiny stainless steel pendant plated in 24k gold that holds two capsules when you're away from home. It's functional jewelry, and jewelry doesn't go in the trash.
Your first order arrives with the canister, Overnighter, and refill pouch inside the shipping box. There isn't another product box inside it, because a beautiful box destined for the recycling bin is still another box.
Designed to Go
The packaging you do need to replace has a different job.
Your capsules come in a plant-based compostable refill pouch rather than a conventional plastic supplement bottle.Or really, plastic anything. When your monthly refill arrives, it comes in that pouch inside a lightweight recyclable paper mailer.
That's it.
The refill system lets us keep sending you the product without sending another canister, bottle, decorative carton, or pile of packaging along with it.
About Our Compostable Refill Pouches
"Compostable" can mean very different things depending on the material and how it's been tested, so this is one area where we think specificity matters.
Our refill packets are made from plant-based compostable materials (not petroleum plastic) and are certified to ASTM D6400, the U.S. standard for industrial compostability. They're also backed by a funded end-of-life composting pathway through a composting stewardship program, so the industrial-composting route isn't just a label on the package. It's a resourced program that actually reaches the material.
Home compost is a second option. The material can safely go in your backyard bin without leaving persistent plastic or microplastics behind. It will break down more slowly and less completely at home than in an industrial facility (similar to something like an avocado pit), which is why we're currently working toward a separate home compostability certification on the finished packaging. Once that certification is complete, we'll update this page and say so directly.
The microplastics distinction is one we take seriously. Conventional plastic doesn't disappear; it shatters into smaller and smaller pieces until it's in the soil, the water, the fish, and you. Multiple independent research teams have now found microplastics in human blood, lungs, placenta, kidneys, livers, and brains (Nihart et al., Nature Medicine, 2025). We chose plant-based compostable material specifically to avoid contributing to that trajectory.
Until then, here's what we can back honestly today:
- Made entirely from plant-based compostable materials
- Certified to ASTM D6400 for industrial composting
- Backed by a funded composting pathway that actually gets the material composted
- Safe to add to home compost, where it will break down more slowly
- Home compost certification on the finished packaging in progress
How We Sourced It
Finding packaging that could meet the less glamorous requirements of a daily supplement took time. Capsules have to be protected from moisture, humidity, shipping, and time. Most compostable materials on the market can't do that reliably.
We spent about two years finding the right material. Only a small number of manufacturers worldwide make home-compostable materials stable enough for supplements, and even fewer are in the US. When we found the one we wanted to work with, we also had to bring on a second vendor for the sealing step, since compostable film requires equipment most co-manufacturers don't have. They happen to be in the same city as our pill manufacturer, which keeps the freight footprint modest.
It's the operational story behind the packaging. Not glamorous, but it's why we can back what we say about it.
Why We Don't Use Plastic Supplement Bottles
Plastic is extraordinarily good at being durable. That works against you when the thing it's protecting lasts a month and the container can last for generations.
Many supplement bottles are technically recyclable, but "recyclable" and "recycled" aren't the same thing. The EPA has put the overall US plastics recycling rate at 8.7%, with HDPE bottles (the type most supplement bottles are made from) at 22.7% in the most recent estimate (EPA, 2023). Whichever number you trust, roughly three out of four bottles don't make it through the recycling stream even when people do everything right.
And it's getting harder, not easier. Collection volumes of PET and HDPE bottles dropped by 89.3 million pounds between 2022 and 2024 (Stina, 2026). The infrastructure this whole system depends on is shrinking while bottles keep on coming.
Supplement bottles fare worse than average even by these standards. They're small, and plenty of programs won't take anything under two inches. They're usually opaque or colored, which is worth less to a reclaimer than clear plastic and harder for sorting equipment to see. And each one arrives with a cotton plug, desiccant packet, foil seal, and a cap. None of those belong in the same recycling stream. You're supposed to disassemble a supplement bottle before recycling. Almost nobody does.
So, technically recyclable. Statistically, landfill.
Rather than build our packaging system around another disposable bottle, we chose one permanent canister and lightweight refills. You keep the canister. We send what you actually need.
Plastic-Free Packaging
Being truly plastic-free isn't just a material choice, it's a design discipline. We use mono-material packaging wherever we can, which eliminates one of the biggest barriers to recycling. Mixed-material packaging (a plastic bottle with a metal lid and a paper label) is one of the top reasons recycling actually fails in practice. Everything in our system is designed to be straightforward at end-of-life: one material, one destination.
Roughly 80% of a product's environmental impact is set at the design stage. Which means the choices we made when we designed Good Kitty (the container types, the material selection, the elimination of secondary packaging) are the ones that matter most.
Paper We Can Trace
Our starter-kit shipping box is made from post-consumer recycled paper and is FSC certified. FSC certification gives us traceability around the paper and the forests its virgin fiber comes from, rather than relying on a vague "responsibly sourced" claim.
Once you've unpacked your Good Kitty, recycle the box.
Monthly refills require even less material. The refill pouch ships in a thin recyclable paper mailer because its primary job is simply getting your capsules from us to you safely. No secondary carton necessary.
Our Packaging Philosophy, in Short
- Make the permanent things worth keeping.
- Use as little disposable packaging as possible.
- Choose compostable materials where they can reliably protect the product.
- Use recyclable, traceable paper where paper makes sense.
- Don't make claims we can't substantiate.
We're not claiming that manufacturing a product has zero environmental impact. It doesn't. This page is specifically about our packaging choices, not an overarching sustainability claim about our entire company.
What we can tell you is what we've actually done with our packaging and what we can verify. Permanent where permanence makes sense. Compostable or recyclable where it doesn't.

I Don't Think We're Going to Save the Planet
My daughter would probably roll her eyes at this entire section. To her generation, we've already blown it. The climate is warming. Fires are now a season in California. Oceans have plastic reefs. AI data centers consume staggering amounts of electricity and water. Cow burps emit a third of our methane, but at least we got steak. Environmental protections get rolled back every election cycle depending on who's in office. Governments argue. Companies greenwash. We adults keep our TVs tuned to sitcoms because this is all too dire to ever fix.
I understand why she feels that way.
I don't think Good Kitty is going to save the planet. Neither is most of what we buy. Anyone claiming otherwise is selling something else.
But I've also reached the age where I think small decisions matter, especially when millions of people make them.
Choosing packaging that won't become microplastics. Building something durable instead of disposable. Manufacturing closer to home when we can. Using paper that's actually certified instead of hoping no one asks. Spending money on the harder choice when the cheaper choice was right there.
None of these decisions reverse climate change. None of them stop sea levels from rising or erase decades of bad policy and corporate indifference. They are simply the things we can control.
I don't know whether these choices move the needle in any measurable way. I do know I'd rather contribute a little less to the problem than shrug my shoulders because the problem is too big.

Frequently Asked Questions
Is Good Kitty packaging plastic-free?
Yes. Our packaging system is designed without conventional petroleum-plastic bottles or secondary plastic packaging. Our permanent canister and Overnighter are stainless steel (the Overnighter plated in 24k gold), our refill pouch uses plant-based compostable material, and our shipping materials are paper-based.
What certifications does the refill pouch carry?
Our refill packets are certified to ASTM D6400, the U.S. standard for industrial compostability. They're backed by a funded composting stewardship program that provides a real end-of-life pathway to industrial composting. We're currently working toward a separate home compostability certification on the finished packaging so we can back home-compost language with independent verification. When that certification lands, we'll update this page.
Can I put the refill pouch in my home compost?
Yes. The material is made from plant-based compostable ingredients that can safely go in a backyard compost bin. It will break down more slowly and less completely than in an industrial composting facility, similar to how something like an avocado pit takes longer than a leaf. It won't leave microplastics or persistent plastic behind in your soil.
Why use stainless steel instead of disposable packaging?
Because the canister isn't intended to be disposed of. We chose stainless steel as a noble material for its durability, reusability, and longevity. The canister is designed to be refilled repeatedly rather than replaced every month. The Overnighter follows the same principle: stainless steel plated in 24k gold, designed as a functional piece of jewelry rather than disposable packaging.
Why don't you use a traditional supplement bottle?
Because we don't need to send you another container every month. Your canister is the container. Your monthly refill pouch replenishes it. That lets us use dramatically less packaging with each refill.
Is your paper packaging recyclable?
Yes. Our starter-kit shipping box is FSC-certified and made with post-consumer recycled paper. Our monthly refill ships in a lightweight recyclable paper mailer.
Is Good Kitty a sustainable company?
We're careful with that word. This page is specifically about our packaging choices. Sustainability across an entire company involves manufacturing, ingredient sourcing, transportation, energy use, and many other factors. Rather than make an overarching claim, we're telling you what we've actually done with our packaging and what we can verify. Permanent where permanence makes sense. Compostable or recyclable where it doesn't.
