The natural evolution of plastic

Vivomer enables brands to move beyond plastic, without compromising on performance, aesthetics, or sustainability. Ideal for unrecyclables, it offers the function of plastic without the waste. Better for health, better for the planet.

No compromises, just innovation that looks good and does good.

Made with plants not plastic

At Shellworks, we’re reimagining materials for a non-toxic, waste-free future.

Over the last five years, we’ve collaborated with nature to create Vivomer™, the natural evolution of plastic. Made from waste biomass, for example from plants, Vivomer is crafted through fermentation and formulation to behave like plastic, but without the harmful legacy.

Vivomer is plastic as it should be - versatile, beautiful, and functional. It can be rigid or flexible, matte or glossy. But unlike conventional plastics, it's always home-compostable, microplastic-free, and free from toxic chemicals like BPA and PFAS.

Safe for our bodies. Gentle on the planet. Ready for the next generation.

Made
at scale

We do what others call impossible, and we do it at scale. Our materials aren't theory, they're products. In the real world. At real volumes. Transforming the future of materials doesn't happen in a vacuum - it happens through relentless testing, iteration, and the belief that there is a better way.

We're here to build it.

Vivomer is completely natural

Plastic Free

Vivomer is a natural biodegradable polymer. Vivomer is free from fossil-based, conventional synthetic plastics and their bio equivalents.

100% Bio-Based

100% bio-based polymer. Vivomer contains minerals and pigments suitable for home composting.

Home compost certified

Vivomer is certified as OK HOME compostable by TUV Austria. All products are designed to break down in healthy home compost within 52 weeks.

Shelf stable + zero waste

Vivomer products are entirely stable in use and will only break down once disposed of. Vivomer has been tested to demonstrate home compostability (TUV OK HOME), Industrial compostability (EN13432), Marine biodegradability (ASTM D6691) and will biodegrade in landfill conditions (ASTM D5511).

No toxins

Vivomer does not contain any toxic
additives as per REACH SVHC lists.

No microplastics

Vivomer will not create persistent microplastics and will biodegrade entirely into elemental compounds (water + CO2) once disposed of.

No petrochemicals

There are no petrochemical derivatives, additives
or polymers present in Vivomer. This includes dyes and pigments.

No Phthalates, PFAS, BPA

We do not add phthalates, PFAS
or BPA in Vivomer formulations.

Engineered to last.
Designed to disappear.

Vivomer pushes the boundary of what is possible in terms of physical properties and shows that sustainable biomaterials can achieve longevity and high performance. No toxicity and no compromises.

Our Promise

When you see Vivomer™ on a product, you're choosing a material made with care and intention. It's made from plants, not plastic. Free from toxins, petrochemicals, and anything that doesn't belong in or on your body. It's our seal that promises it's always home-compostable, microplastic-free, and safe for the world it returns to. It's proof that performance, safety, and sustainability can all live in one material.

a. Our in-house composters filled with products and food waste that provide us with real-world data.

b. No matter the formulation, rigid or flexible, matte or glossy, every version of Vivomer is tested to the same rigorous standards. Some degrade faster than others, and some surprise us along the way, but one thing remains constant: they all break down, exactly as nature intended.

Holes in a bottle from biodegradation are measured using calipers.

c. We combine qualitative data with quantitative data to understand how each product form we create breaks down in real-world conditions.

d. At Shellworks HQ, we run our own compost system, powered by our team's food waste, to replicate real-world home composting conditions. It's how we turn the everyday art of composting into a rigorous science.

e. Every degradation pattern is beautifully unique, highlighting nature's variability and the organic process at work. The end result, however, as certified by TÜV Austria, is always complete degradation - back to it's original organic building blocks, ready to restart its cycle of life.

Degradation samples are taken out of an oven to dry out the product and pause the biodegradation process for inspection.

f. Pulling pieces from home compost pauses the process, a snapshot of biodegradation frozen in time. We keep these fragments to document the journey, and honestly, we think they're beautiful. A quiet momento of what the future of materials is.
