C2C Coffee Cup Made From Spent Coffee Grounds

If you’ve ever sipped coffee from a disposable cup and wondered where it ends up, you’re not alone. Most paper coffee cups aren’t truly recyclable, and billions are landfilled yearly. But what if your cup could be made from yesterday’s coffee waste — right in the cafe where you’re drinking?

The C2C coffee cup is made from 15–95% used coffee grounds, depending on the cafe setup, blended with paper pulp and corn-based polylactide resin. It’s molded in-store, fully biodegradable, and designed for a circular cafe waste system.

Coffee shops produce a constant stream of used grounds — often seen as a nuisance. But Canadian designer Saleem Khattak saw potential. His solution? The C2C (“cradle-to-cradle”) coffee cup, which turns this waste into a functional, tactile product with minimal environmental impact.

How the C2C Cup Is Made

The C2C cup is produced on-site at the café using the cafe’s own spent coffee grounds. These are mixed with paper pulp and a polylactide resin derived from corn dextrose. This mixture is then pressure-molded into cup form. After molding, the cups are dried and cooled, often during transport or storage, saving additional energy.

This local production method means no unnecessary fuel is burned transporting raw materials or finished goods — a direct strike against the waste and emissions of conventional disposable cup supply chains.

Design Features and User Experience

The C2C cup isn’t just sustainable — it’s thoughtfully designed. Its shape includes a directional feature for easier handling, especially for those with limited grip strength. When paired with a lid, the drinking opening is always intuitively positioned. The overall form is meant to feel more secure and user-friendly than a typical disposable cup.

The designers also prioritized visibility in the making process. The production method was conceived to be part of the customer experience inside the café.

C2C Maker: On-Site Manufacturing Unit

The C2C cup is produced using a device called the C2C-Maker. This unit is designed to fit under or behind the café counter, with parts of the machinery left visible. The main mold, forming, and cooling elements are typically positioned above the counter for easy observation.

The manufacturing becomes part of the café atmosphere — a small-scale, visible cycle of reuse that engages customers with the full lifecycle of their cup.

What’s Actually In Your C2C Cup?

Ideally, the coffee grounds used to make your cup would come from your own brew. Due to necessary steps like mixing, forming, drying, and cooling, that’s not usually possible — your cup’s grounds will likely come from another customer’s coffee. But functionally, every brew has the potential to create its own cup.

If every café installed a C2C-Maker, the coffee ground content in each cup would average around 15%. The rest is mostly paper pulp and polylactide resin. In high-profile cafes that source extra grounds from elsewhere, the coffee content can rise to 90–95%, with the resin used only as a binder and sealant.

Frequently Asked Questions

What is a C2C coffee cup?

A C2C coffee cup is a disposable cup made from used coffee grounds, paper pulp, and polylactide resin (a plant-based plastic derived from corn dextrose). It is produced on-site at cafés using their own spent coffee waste.

How much coffee grounds are in a C2C cup?

If every café has a C2C-Maker, the coffee ground content is around 15%, with 85% pulp and resin. In high-volume setups that import extra grounds, coffee content can reach 90–95%, with resin only as a binder.

What is the C2C-Maker?

The C2C-Maker is the on-site machine that produces the C2C cup. It is installed under or behind the café counter, with visible parts such as the mold and cooling tree positioned above the counter for transparency.

Is the C2C coffee cup biodegradable?

Yes, the C2C coffee cup is fully biodegradable and compostable. All its components — coffee grounds, paper pulp, and polylactide resin — break down naturally without toxic residue.

Where is the C2C coffee cup designed?

The C2C coffee cup was designed by Saleem Khattak from Canada. It was conceived as part of a cradle-to-cradle waste reduction philosophy, aiming to eliminate unnecessary transport and landfill contribution.

Why use coffee grounds in a disposable cup?

Using coffee grounds repurposes cafe waste that would otherwise be discarded. It reduces reliance on virgin materials, cuts transport emissions, and creates a circular system where waste becomes a useful product.
