Creating Cleaner Cities: Policy Options for Solid Waste Management
This paper considers policy options for providing solid waste management services in low- and middle-income cities. It covers technologies for storage, collection and transport, and diversion or disposal; considers who should provide services; and examines different approaches to compliance and funding.

Solid waste management is an urgent, system-wide task as developing cities grow. Volumes are rising, the composition is harder to manage, and the costs of failure—for health, climate, and infrastructure—are high. It is also a visible test of municipal competence.
Experience from cities worldwide offers clear lessons on delivering effective solid waste management.
This paper highlights key considerations for city leaders:
1. Optimise access, cost efficiency, and reliability. Household or communal storage needs to be close enough to minimise walking distance, yet large enough—and supported by transfer stations—to lower transport costs. Predictable timetables improve household compliance but require operational discipline.
2. Retain value where markets allow, but dispose safely where they do not. Segregation at source and reliable pick-up raise the quantity and price of recyclables. Where markets are thin, sanitary disposal and emissions control need to be prioritised.
3. Match provider to task, and integrate informal capacity. Trunk collection and disposal require public coordination. Outsourcing or public–private partnerships can add capability where risks and performance are contractible, but need to be monitored and regulated. Recognising and equipping informal collectors expands coverage and recovery at low fiscal cost.
4. Make compliance the easy choice. Deterrence rests on the likelihood of enforcement, not simply the value of the fine. Awareness campaigns can address information gaps, and visible service builds trust. Simple, transparent rules limit discretion and bribery.
5. Price with a two-part logic and protect the poor. Cover fixed network costs with a modest fixed charge; add a variable element where enforcement is credible. Where capacity is low, start with existing taxes or flat fees to avoid pushing households to dump. Use rebates to safeguard low-income users.
Finally, sequencing matters. Municipalities’ SWM systems should evolve to align with local needs and enforcement capacity, willingness to pay, changing environmental objectives, and national-level priorities.
