Why Cassava? The Plant Behind Our Litter

There is a plant that grows in the red soils of Southeast Asia, across sub-Saharan Africa, through the river basins of South America. It has fed communities on three continents for thousands of years — not because it is rare or remarkable to look at, but because it is quietly, unusually good at what it does.

Cassava grows where other crops struggle. It tolerates drought, thrives in poor soil, and asks for very little in return. From the moment it is planted, it is ready to harvest in eight months. That cycle repeats, season after season, without depleting the ground beneath it.

We built Petabite around this plant.

From root to granule

After harvest, the roots are peeled, washed, and milled into a fine white starch — the same ingredient found in tapioca, in bread flour, in biodegradable packaging. It is one of the most versatile plant starches in the world, and it has a particular quality that caught our attention early: it absorbs moisture quickly and clumps firmly on contact, without the need for chemical binders or synthetic additives.

That behaviour is not engineered. It is simply what cassava starch does.

In Snow, we paired it with baking soda — nothing more. The starch draws in liquid and holds it. The baking soda neutralises odour at its source, not by masking it with fragrance, but by breaking down the compounds themselves. Two ingredients, each with a clear role, working closely together.

What cassava makes possible

When we began developing Petabite, we were drawn to cassava for a reason that had nothing to do with novelty. We were drawn to it because it is renewable in a way that most litter ingredients are not. It regrows each season. It biodegrades at the end of its life. And because it is light relative to mineral-based materials, it carries a smaller footprint from field to front door.

That lightness shaped Snow — a litter made entirely from plants, designed for cat owners who want the simplest possible formula.

But not every household needs the same thing. Some use automatic litter systems that demand a heavier, more structured granule. That is where mineral becomes essential — and where Terra begins.

Two expressions of one ingredient

Terra pairs cassava with natural mineral to create a granule built for precision. The cassava starch provides absorption. The mineral provides weight and structure — qualities that matter deeply in automatic systems, where each granule must behave predictably. BASF dust-binding technology holds loose fines to the surface, so they stay where they belong rather than drifting into the air around them.

It is a different formulation with a different purpose, but the starting point is the same. Cassava sits at the centre of both products because it earned its place there — through performance, through renewability, through the kind of quiet reliability that does not call attention to itself.

A plant that has sustained communities for centuries, now doing one more small thing well.
