Introduction

Welcome to the presentation page for our butter churn project! In a modern world often reliant on sophisticated technology, we've chosen to return to simple, sustainable solutions for essential everyday needs. Our inspiration stems in particular from the French Butter Crisis of 2017, an event that highlighted the vulnerability of our butter supply.


Faced with this crisis, we set out to design a solution accessible to everyone, through the creation of a low-tech butter churn. Our aim is to give people back control over the production of this staple product, by offering a simple, affordable and environmentally-friendly alternative. Through this project, we aim to demonstrate that low-impact technologies can be just as effective, if not more so, than their high-tech counterparts, while promoting greater food autonomy within communities.


Unfortunately, this project could not be completed, but it is a promising start for the future. The project requires very little equipment and costs just €3 instead of €50.
