01 A real ban
It is worth placing it in time, because that is what makes the decision notable. In 2008, most European countries were still debating whether to charge a few cents per bag. Here the choice was to ban them outright, more than a decade ahead of much of the world.
The effect is visible before you have left the airport, and certainly on the first street. There are no plastic bags snagged on fences, in the drains, or in the ditches of the roads leaving the city. It is an absence you do not realise you were used to seeing until it disappears.
02 The last Saturday of every month
One day a month, repeated for three decades. Cleanliness is not a campaign: it is a calendar.
The second piece of the system is umuganda, institutionalised in 1995. It consists of a compulsory day of community work for people aged between 16 and 65, held on the last Saturday of every month across the country. The specific projects are decided locally by each community and its leaders.
What is done on those days varies: cleaning, building, repairing, improving something in the immediate surroundings. Cleaning is only one part of the programme, not the whole of it. But repeated month after month for three decades, the cleaning part accumulates a very visible effect on public space.
For the traveller there is a practical consequence worth noting: on the last Saturday of every month, much activity stops for the morning. Shops closed, reduced traffic and streets given over to the session. It is not a serious inconvenience, but it is a morning that has to be planned differently.
03 Why they work together
What is interesting about the case is not each measure separately, but how they hold each other up. Plastic bag bans have been passed in dozens of countries, and in many they have come to nothing because there was no way for the rule to sink into daily habit.
Here the ban landed on a country that had since 1995 had a fixed, monthly, compulsory appointment devoted to the shared environment. That repetition — a known date, every month, for almost three decades — is what turned an administrative rule into a collective habit.
The result is that Kigali appears repeatedly on lists of the cleanest cities in Africa, and frequently on lists of the cleanest capitals in the world. It is not a brochure impression: it is the first thing anyone arriving from another capital in the region comments on.
04 What it means for you
The first is a packing matter. It is worth taking plastic bags out of your case before leaving home: the ones around clothes, in the washbag, the shopping bags one drags around without noticing. If they arrive with you, they will probably be removed on entry, and avoiding that is straightforward.
The practical alternative is to carry fabric bags for what plastic usually solves: damp clothes, shoes, the day's shopping. In the country that is the norm, and you will not find a plastic bag in any shop to get you out of trouble.

And the second is about the calendar: check which day the last Saturday of the month falls on before closing your itinerary. If it coincides with your only morning in the city, it is better to leave that slot for something that does not depend on open shops or on moving around much, and keep the travelling for the afternoon.
