The manufacturing of paper cups involves many steps of sourcing, treatment, and long-distance transportation of materials, as well as the use of acids, bleach and plastic. Paper cups are lined with plastic to make them waterproof and therefore cannot be recycled as paper. Just like plastic cups, they end up in landfills for hundreds of years where they break down into even more harmful microplastics. Most paper cups marketed as “sustainable” are lined with renewable - but not recyclable or biodegradable - materials. And while some bioplastics may be compostable, this process is expensive and not commonly available in most geographies.

We use clay to manufacture our cups. Clay is an abundant natural resource and has been used by humans for thousands of years to package and transport food and drink. We only use clay that has been sustainably sourced. Other than that, the only ingredients we add are water and salt. Our cups come from the earth and can return to the earth without creating any harm or requiring any further treatment.
