Sanitation

Roles: waste, collector, bin, route, disposal-site, recycling, accumulation, pickup-schedule

Municipal waste management — the infrastructure of collecting, transporting, and disposing of things a community no longer needs. As a source domain, sanitation provides a rich vocabulary for automatic cleanup systems: garbage accumulates, collectors run on schedules, bins have capacity limits, and the distinction between trash and recyclable material maps onto questions about what can be reclaimed versus what must be destroyed.
