A second life for every café’s waste stream.

Grounded — In development

Grounded turns spent espresso pucks into a workable composite material — pressed into reusable cups, plates and small homewares, then returned to the cafés they came from. The whole loop closes inside a city.

01 · Brief

A waste stream every café in the country produces, every single day.

A busy café in Cape Town generates 8–15 kg of spent coffee grounds a day. Multiplied across the country, that’s tens of thousands of tonnes of high-quality organic feedstock heading to landfill.

The brief: turn that waste into a material the same café will gladly buy back — in a form their customers actually want to use.

02 · The process

From café waste back to café shelf.

The process is deliberately simple: a small dry-mix-press line that fits inside a workshop. Each batch traces back to the cafés it came from, so partners can see exactly how their grounds re-enter the world.

  • 1. Collect. Spent grounds picked up daily from partner cafés, kept dry and uncontaminated.
  • 2. Dry. Low-temperature tumble-drying drops moisture below the binding threshold without scorching the grounds.
  • 3. Bind. Mixed with a plant-based resin sourced locally. No petroleum-based plastics in the recipe.
  • 4. Press. Heat-pressed in a tooled mould; finished, branded and shipped back to the café network.

03 · The range

Built for the café counter first.

The first product line covers the formats a barista uses every shift. Each piece carries a faint coffee scent and a fine speckled finish — the material doesn’t pretend to be ceramic, and that’s the point.

When pieces wear out, they go back to Grounded for grinding and re-pressing. Material stays in circulation; nothing earns a one-way trip to landfill.

8 oz cup

The everyday espresso-and-flat-white format. Brand-stampable lid optional.

12 oz cup

Cappuccino, latte, cold brew. Pairs with a saucer or stands on its own.

Saucer

Same material body as the cup; nests in stacks of twelve for back-of-house storage.

Homeware

Plates, planters and small bowls for cafés that want the material on the retail shelf.

Pilot loop forming — partner cafés open

We’re building the first Grounded pilot loop with a small group of independent cafés in Cape Town. Roasters, café groups and material designers welcome.
