Description
A butter churn transforms cream into butter by stirring/agitating it. The rotating mechanism separates the fats from the liquid contained in the cream.
Introduction
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, which highlighted the vulnerability of our butter supply.
In light of this crisis, we have designed an accessible solutio - a low-tech butter churn. Our aim is to give back the control to the people for the production of this staple product, offering a simple, affordable + environmentally-friendly alternative. This project aims 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 and resilience within communities.
Unfortunately, this project was not completed, but it's a promising start for the future. The project requires very little equipment and costs just €3 instead of €50.
