Inspiration
It started with a simple question one of our team members couldn't shake: why does the same market that grows food also produce a dump right next to it?
In many communities across Africa and the Global South, organic waste — fruit peels, crop residue, food scraps — piles up in open dumps. Those dumps rot under the sun, releasing methane gas and breeding disease. And just a few kilometres away, the same farmers who generated that waste are spending money they don't have on synthetic fertiliser to replace the nutrients they just threw away.
That gap — between waste and need, between damage and value — is what inspired EcoLoop. We didn't want to build another app. We wanted to build a loop that didn't exist yet: a system that takes what communities are throwing away and gives it back to them as something they actually need.
What it does
EcoLoop is a community-run circular economy system that turns organic waste into compost, biogas, and income — keeping the value inside the communities that generate it.
It works in three steps:
Collect. Community waste hubs at local markets and farms — simple labeled bins managed by local youth volunteers or women's cooperatives — gather organic waste separately from other trash.
Convert. That waste is either composted using low-tech proven methods, or fed into small biodigesters that produce clean cooking gas for nearby households.
Redistribute. The compost goes back to local farmers at low or zero cost. Biogas goes to households. Any surplus revenue — or future carbon credits — funds the loop's operation and local priorities, decided by the community itself.
The key insight is simple: the same community generates the waste and needs the outputs. EcoLoop just builds the bridge between them.
How we built it
We didn't start with tech. We started with people.
We spent the first part of the hackathon mapping the actual stakeholders: market vendors, smallholder farmers, youth who need flexible income, local government waste officers, and women's cooperatives that already operate informal collection systems in many communities. We asked: who actually touches the waste? Who needs the output? Who has the trust of the community?
From there we built:
A full system design — stakeholder map, waste flow diagram, and value redistribution model showing exactly how money and resources circulate through the loop.
A community engagement playbook — how to recruit the first local operator, set up the first collection hub, and earn community trust within 30 days.
A basic financial model — cost per tonne of waste processed, compost revenue projections, and a break-even timeline that shows the loop can sustain itself by month 6 without external grants.
A pilot selection framework — criteria for choosing the right first community, including waste density, existing cooperative structures, and soil need.
We grounded every decision in what already works: biodigestion and composting are proven, low-maintenance, locally repairable technologies. We chose tools over novelty.
Challenges we ran into
Governance was the hardest part. Who owns the hub? Who controls the revenue? We went through three different models before landing on a community co-operative structure where decisions are made collectively and no single outside party holds the money.
We also had to fight the "NGO trap" — the risk that EcoLoop becomes another well-intentioned programme that communities depend on but don't own. Every design decision had to pass one test: would this still run if we left after year one?
There was also the challenge of scope honesty. We had bigger ideas — a digital tracking platform, a carbon credit marketplace, a city-wide rollout plan. We cut all of it. The honest version of EcoLoop, the one that could actually be piloted in 30 days, is simpler. That simplicity is a feature, not a compromise.
Accomplishments that we're proud of
We're proud that EcoLoop requires no exotic technology, no internet connection, and no imported spare parts to run its core loop. That was a deliberate goal and we hit it.
We're proud of the financial model showing self-sufficiency by month 6 — because a system that needs grants forever isn't really a system, it's a dependency.
We're proud that equity isn't a section at the end of our proposal — it's the architecture. Women vendors and smallholder farmers aren't beneficiaries of EcoLoop. They are its operators and owners.
And honestly? We're proud that when we traced the journey of one cassava peel from a market stall to a farmer's field and back — it actually made sense. The loop closes. That felt like the real accomplishment.
What we learned
The biggest lesson: the technology is not the bottleneck. Composting works. Biodigesters work. They've worked for decades. The real challenge is trust, governance, and the incentive structure. Communities need to see that value flows back to them — not to an outside organisation, not to a startup, not to us.
We also learned that "circular economy" is an abstract phrase until you map one specific person's day. The moment we zoomed in on a single market vendor, a single cargo bike collection, a single farmer receiving compost — everything became concrete. Abstract language loses judges. Specific stories win them.
And we learned that simplicity is a design choice that requires more discipline than complexity. It's easy to add features. It's hard to remove them.
What's next for EcoLOOP
30 days: Partner with one market association and one farmers' cooperative to run a proof-of-concept collection point. Measure waste volume, collection reliability, and community uptake. No biodigester yet — just collection and composting. Keep it honest.
6 months: Run a full loop — collection, composting, redistribution — across 3 community hubs with 20+ participating vendors. Measure soil improvement, methane reduction estimate, and whether the financial model actually holds.
Year 2: Introduce biogas conversion at the highest-volume hubs. Begin documenting carbon impact with the goal of registering under a voluntary carbon standard. Use carbon revenue to expand — not to pay outside consultants, but to fund the next community hub.
The goal is not to scale EcoLoop into a company. The goal is to make EcoLoop replicable enough that communities can copy it without us. That's what a real loop looks like.
