THE EGGSHELL PROJECT

Giving new life to biowaste

MANUFACTURA, a Mexican design studio, has launched ‘The Eggshell Project’ with the aim of transforming organic waste into sustainable building materials. With food waste accounting for a third of global production, this project seeks to address both environmental and socio-economic issues by reusing discarded eggshells. The project focuses on using these eggshells in combination with bio-binders to create bioceramic bricks, eliminating the need for traditional firing processes. The mixture is 3D printed into various geometric shapes, resulting in building components suitable for a variety of architectural applications. The research led to the development of two primary structures: the Eggshell Wall, made up of 105 unique blocks that are assembled based on their geometry, and the Eggshell Column, made up of 26 interlocking pieces that provide stability through their shape. The eggshells used were collected over two months from various restaurants in Mexico City, ensuring a 100% sustainable and circular process. By integrating computer-aided design with digital manufacturing, the project demonstrates the potential to transform organic waste into valuable building materials.
