We owe you an apology. Our beloved Plant Protectors have been out of stock for longer than we'd like, and we know many of you have been patiently (and not so patiently) waiting.

We thought we were being clever. "Let's upgrade the production line, we've got plenty of stock to cover us in the meantime." Famous last words. Turns out the Aqua Plant Protectors are so popular that our buffer stock vanished faster than we could have planned for. A good problem to have, but a problem all the same, and one we're fixing right now.

Meanwhile, the equipment for our upgraded production line decided to take the scenic route A cruise around the pacific.

The good news? The upgraded line is ready and we have stock.

To everyone who has been waiting, emailing, calling, and messaging us, thank you. Your demand tells us we're onto something special.

We’re proud to see the PolyNatural team featured in the latest issue of Avenues magazine.

The story, “Naturally clever,” explores how our Christchurch-based engineers and scientists are using naturally occurring, fermentation-derived polymers to create high-performance alternatives to conventional petrochemical products.

From viticulture clips and plant protectors to wool w**d mats, our focus is practical: materials engineered to perform for their intended lifespan, then return safely to nature at end of life—without leaving persistent plastic or microplastics behind.

A big thank you to Avenues and Liam Stretch for telling our story, and to the growers, customers, partners and wider team helping turn better material solutions into real-world products.

Why is coffee chaff inside our Aqua Plant Protector?

We embed coffee silverskin/chaff inside a next‑generation biotechnology creating a bio‑composite that is strong in the paddock and designed to biodegrade in soil and water over time

The chaff acts as a lignocellulosic reinforcement, helping tune mechanical performance and processability while also providing an organic phase that microbes can readily digest at end‑of‑life.

For roasters, this turns a low‑value waste stream into a visible climate and biodiversity solution; for planters, it means robust protection today and no plastic legacy tomorrow.

This is circular design in action: we start with a problem material, and build a product around its strengths.

Tiny flakes, massive volume.

Coffee silverskin/chaff is only a small fraction of each bean by weight – typically around 2% of green or roasted coffee, depending on the process and variety.

New Zealand imports around 12,000 tonnes of coffee a year. That equates to approximately 240 tonnes of coffee silverskin/chaff.

When we talk about “waste to value” at PolyNatural, this is what we mean: taking streams like coffee chaff that already exist at scale and turning them into something that actively restores ecosystems. learn more at polynatural.nz

What actually is that ‘coffee silverskin’ we keep talking about?

Every green coffee bean has a thin, papery skin that clings to the seed inside the coffee cherry.

Roasters call it silverskin or chaff, and it flakes off during roasting, collecting in the chaff tray or cyclone as a very light, dry byproduct

Traditionally, chaff has been treated as waste and sent to landfill or burned, even though it’s a natural, lignocellulosic material rich in useful compounds like caffeine and polyphenols.

At PolyNatural, we see chaff differently: it’s not “waste”, it’s a circular ingredient.
