Join the adventure!

Compostons Ensemble runs entirely thanks to its volunteers. You don't need to be an expert — just willing to pitch in.

🌍
Take action for the planet

Every caddy dropped off means less waste buried in the ground and more organic matter returned to the soil. A simple gesture with a real impact.

🏘️
Build local connections

Our open sessions are friendly moments of exchange. People come together, swap seeds, and share gardening tips over a shared passion.

📚
Learn by doing

Composting is a fascinating natural science. As a volunteer, you'll deepen your knowledge and pass it on to others.

⚠️ Windrow Alert

Is the windrow not heating up? The most likely cause is a lack of carbon. Wood chips are essential to balance the nitrogen-rich food scraps. Please always respect:1 part caddy waste  +  3 parts wood chips
