Background
Urban solid waste management in Cambodia is a public service system that covers waste generation, collection, transport, and final disposal through municipal authorities, service operators, and national policy coordination. In Phnom Penh, daily waste volumes are a practical indicator of city sanitation demand and the performance of collection and disposal infrastructure.
Cambodia’s environmental administration has increasingly linked waste reduction to public behavior, plastic-use reduction, and local cleanliness campaigns. The Ministry of Environment has promoted nationwide awareness initiatives on waste sorting, proper disposal, and reduced plastic bag use, while also supporting sub-national administrations with cleaning equipment and waste bins for public institutions.
Key Developments
The Ministry of Environment stated that 2,335.06 tonnes of waste were collected and transported to disposal sites in Phnom Penh on 15 April 2026, the second day of the Khmer New Year holiday. According to the ministry, this represented a 44% decrease compared with the daily waste volume collected on normal days in the capital.
Ministry spokesperson Khvay Atitya said the decline was associated with stronger public participation in proper waste disposal and reduced plastic use during the 2026 Khmer New Year period. The ministry said the result reflected wider public awareness of the effects of waste and plastic waste.
The ministry also outlined broader cleanliness efforts involving relevant authorities, the private sector, youth groups, associations, civil society organizations, students, and residents. It said these efforts included behavior-change campaigns, school-based awareness linked to families and communities, and mass public participation in campaigns such as “Today I Will Not Use Plastic Bags,” “Clean Cambodia, Khmer Can Do,” and a national road anti-litter initiative.
The ministry further said it has supported sub-national administrations and local authorities by providing materials for waste transport and cleaning activities, as well as gradually distributing waste bins to health centers, schools, and pagodas across the country.
Implications
The reported decline in waste collected in Phnom Penh provides a reference point for Cambodia’s urban sanitation management during major public holidays, when population movement and consumption patterns can differ from normal days. For policymakers and municipal service planners, changes in collected waste volumes can inform assessments of collection demand, public behavior, and the reach of waste-reduction campaigns.
The update also indicates how environmental policy implementation in Cambodia combines infrastructure services with public-awareness measures. Businesses, local administrations, and development partners tracking municipal services and plastic reduction policy may use such figures as an operational signal of how behavior-change campaigns interact with waste management systems.
