Compost as Curriculum: What Soil Can Teach Us About Systems Thinking
“Nothing is waste, only misplaced potential.”
There’s a quiet alchemy that happens when we stop trying to control the death and decay. When we let carrot tops, eggshells, and coffee grounds soften back into the earth, they whisper something we forget in classrooms and economies alike: nothing is waste, only misplaced potential.
The Lesson Beneath Our Feet
Compost is not just rot - it’s relation.
Every pile tells a story of what we consume, what we discard, and what we imagine can be transformed. In a culture obsessed with growth, compost reminds us that thriving is not the same as expanding. The most fertile soil is not the one that grows forever, but the one that knows when to rest, to return, to release.
“The most fertile soil is not the one that grows forever, but the one that knows when to rest.”
This is what economist Kate Raworth calls the Doughnut Economy - a model that defines a safe and just space for humanity between the social foundation and the ecological ceiling. Too little, and people fall short of meeting their needs. Too much, and ecosystems collapse under excess.
Compost, balanced and patient, shows us what enough looks like in practice.
“We are all compost in training,” a farmer once told me, grinning through a handful of damp soil. Learning itself is a kind of decomposition - ideas break down, mix, ferment, and, with time, give rise to something fertile.
Education as Decomposition
Traditional schooling often treats knowledge like a sealed package - pre-measured, standardized, delivered on schedule. But the real world doesn’t work like that, and neither does soil.
When students engage with composting, literally or metaphorically, they witness a pedagogy of process. They learn that “waste” is socially constructed, that cycles matter more than straight lines, and that renewal comes through release. Compost doesn’t demand endless accumulation; it teaches enoughness.
Just as Raworth argues that economies must thrive without growth, our classrooms must learn to transform without excess. Education, too, can overproduce - more content, more testing, more metrics - while starving what matters most: connection, creativity, and care. Compost invites us to slow down, to re-imagine learning as nutrient cycling instead of extraction. Boundaries can make us more creative rather than less.
Circular Systems, Living Classrooms
In a linear economy, things move one way - from extraction to disposal. Composting flips that script, revealing that decay and regeneration are part of the same process. What if our classrooms, schools, and communities worked that way too?
A circular (doughnut) classroom reuses experiences, reflections, and mistakes as raw material for new growth. Lessons compost into projects; failures feed inquiry. Knowledge returns to the soil of community, ready to sprout again in new forms.
The soil doesn’t grow endlessly upward; it deepens. So should we.
Practices for Educators & Communities
If you want to start small:
Observe the process. Invite learners to draw, touch, and smell compost at different stages.
Map material flows. Where do classroom or community resources begin and end? Where could they loop back?
Create a reuse hub. Turn scraps, paper, or leaves into living metaphors for systems repair.
Rethink waste and rest. Degrowth isn’t deprivation; it’s design. It’s the wisdom to stop when systems are full and honor balance over expansion.
Toward a Regenerative Pedagogy
Compost is the ultimate (de)curriculum: it unlearns hierarchy, decentralizes control, and insists that even the smallest organisms have value. It models what Duck on the Fox believes at its core: that education, like soil, is alive - and that nothing can grow forever without breaking the circle that sustains it.
When we stop treating learning as something to extract and start seeing it as something to cultivate, the classroom begins to smell like earth: damp, hopeful, and full of life.
