Before we settled on teaching household-level composting, we tried a shared community compost site meant to serve several compounds at once. It didn't work, and it's worth being honest about why, since the failure directly shaped the programme we run today.
Why the shared site broke down
Without a single party clearly responsible for turning and maintaining the pile, contributions became inconsistent, some households added material without turning it in, others stopped participating once the smell became unpleasant from neglect. The core problem was diffuse responsibility: when a pile belongs to everyone in theory, in practice it tends to belong to no one in particular, and the daily maintenance a compost pile actually needs, turning, balancing wet and dry material, simply didn't happen consistently enough.
Within a couple of months, the site had become more of a nuisance than a resource, attracting complaints from nearby households rather than the enthusiasm we'd hoped for, and we made the call to shut it down rather than let it continue degrading goodwill toward composting generally.
What we built instead
The lesson we carried forward was that composting works best when responsibility sits with a single household or a very small, committed group, not a diffuse shared site where no individual feels direct ownership of the outcome. Our current model, teaching household-level composting directly through hands-on demonstrations at our monthly sessions, grew out of that failed experiment, and it has proven far more durable since, precisely because each household is responsible for, and benefits directly from, its own pile.
We share this story fairly openly at our sessions now, mostly because it's a useful, concrete example of why the model we teach looks the way it does, rather than an untested theory. Households considering composting can see our current session schedule on the Get Involved page.
