Habits formed early tend to last. That's the simple logic behind our schools programme, which brings hands-on lessons in the three Rs — reduce, reuse, recycle — directly into primary school classrooms and compounds across Kasarani, rather than waiting for waste habits to be formed, or not formed, later in life.
Why we start with primary schools
Adults are, frankly, harder to retrain than children. A household that has spent decades mixing all its waste into one bin has a habit that takes real, sustained effort to change, however clearly the benefits of segregation are explained. Children, by contrast, are still forming their basic habits around everyday tasks like disposing of waste, and lessons that stick at age nine or ten tend to carry into adulthood in a way that a single adult training session rarely achieves on its own.
There's a second, less obvious benefit too: children who learn to segregate waste and understand why it matters often bring that habit home, prompting household-level change that our adult-focused outreach alone wouldn't reach as effectively. A school session doesn't just teach one child; it often nudges an entire household.
What a typical session covers
Reduce
We start with the R that gets the least attention elsewhere: reducing waste before it's even generated. Simple, concrete examples work best with this age group — carrying a reusable water bottle instead of buying single-use ones, choosing snacks with less packaging, repairing rather than discarding a broken item where possible.
Reuse
Sessions include hands-on activities turning what would be waste into something usable — plastic bottles repurposed as planters, cardboard turned into craft materials. The goal isn't the craft itself so much as shifting how children see "waste" in the first place: not automatically rubbish, but sometimes a resource that hasn't found its next use yet.
Recycle
Finally, we cover practical segregation — the same three-bin system (organic, recyclable, general) we teach households, adapted to a classroom or school compound setting, along with an explanation of what actually happens to sorted waste after it leaves the school, including a look at how our plastic buy-back initiative turns sorted plastic into income.
Making it stick beyond a single visit
A single classroom session, however engaging, rarely changes behaviour on its own. Where schools are willing, we set up simple three-bin stations in the compound itself, so that segregation becomes a daily, practical habit rather than a one-off lesson remembered only in the abstract. We also encourage schools to nominate a small group of "waste monitors" among older students, who help keep the system running and answer younger students' questions between our visits.
This follow-through matters more than the initial session. Schools that adopt ongoing bin stations and student monitors see the habit persist; schools that treat the visit as a one-time event tend to see segregation fade within a few months, which is a pattern we've learned to plan around rather than ignore.
What schools need to bring, and what we provide
We provide the session content, basic demonstration materials, and guidance on setting up a three-bin system suited to the school's compound. Schools provide the space, a willing teacher or administrator to help sustain the habit after we leave, and, where possible, containers for the ongoing bin stations — often simple repurposed items rather than anything that needs to be purchased new.
Why this connects to our wider mission
Every other programme we run — door-to-door collection, the buy-back initiative, community clean-ups — depends on residents understanding why segregation matters and being willing to practise it consistently. Reaching children early means, over time, a growing share of the adults on our future collection routes will already understand and practise good waste habits before we ever knock on their door, rather than needing to be taught from scratch as adults.
How sessions differ across age groups
We adjust session content noticeably between younger and older primary pupils. Younger children respond best to concrete, sensory activities — sorting games, simple craft reuse projects — with less emphasis on abstract explanation of why segregation matters. Older pupils, closer to the age where they're forming lasting habits and beginning to understand systems beyond their own household, get more direct engagement with the fuller picture: where sorted waste actually goes, how the buy-back initiative works, and the basic health and environmental reasoning behind segregation. Matching content to age has made a noticeable difference in how well lessons actually stick, compared to a single generic session pitched at the whole primary range.
What we're planning to add to the programme
Based on feedback from participating teachers, we're developing a simple take-home component — a short activity pupils can do with their household, like starting a small compost container together, that extends the classroom lesson into an actual family habit rather than leaving that bridge entirely to chance. Early informal trials of this suggest it noticeably increases how often lessons actually translate into household-level change, which is ultimately the outcome we care about most.
How we measure whether a session actually worked
Rather than relying purely on how engaged pupils seemed during a session, we follow up with participating teachers a few weeks later to ask whether the classroom's bin station is still being used correctly, which is a more honest indicator of impact than immediate enthusiasm on the day itself. Schools where follow-up shows the habit holding are the ones we point to as models when introducing the programme to new schools considering joining.
Frequently asked questions
Is the schools programme free for schools to join?
Yes. We run sessions at no cost to the school, since expanding good waste habits among children is core to our mission, not a paid service.
How long does a typical session last?
Sessions usually run for a single lesson period, though we can arrange a longer or multi-visit programme for schools that want a deeper engagement across a term.
Can our school set up a permanent bin station with your help?
Yes, and we recommend it. Schools with ongoing bin stations and student monitors see far better long-term results than those with a single one-off visit.
If your school would like to book a session, reach out through our Get Involved page — we schedule sessions on a rolling basis across the term.
