What a Waste 3.0: Latest Trends in Global Waste Management
The World Bank Group has released its flagship report, What a Waste 3.0. As the third edition of the series following the 2012 and 2018 reports, it presents a comprehensive overview of the current state of global solid waste management and the challenges ahead, with projections through 2050.
Based on data from 217 countries and economies and 262 cities, the report presents the current state and challenges of solid waste management, along with projections through 2050. Waste management is closely linked to urban sustainability, living conditions, and economic competitiveness, and its importance continues to grow globally. It is also a critical sector for economic growth, job creation, and resilience. Japan has long been engaged in this field, and its experience offers valuable insights for countries facing rapid urbanization and increasing waste.
Key Findings of “What a Waste 3.0”
• Waste will continue to grow: Without significant changes, global waste volumes are projected to increase by around 50% by 2050.
• A large share of waste is mismanaged: Approximately one-third of global waste is not properly collected or treated.
• Policy and investment can make a difference: With appropriate policies and infrastructure investment, countries can curb waste growth while supporting economic development.
• Waste management supports jobs and the economy: The sector already generates significant employment and has strong potential for further economic opportunities.
Japan’s Experience
Japan has developed an integrated waste management system combining policy, technology, and citizen participation. The report highlights examples such as waste separation with strong citizen participation, food waste recycling, and disaster waste management, which offer valuable insights for other countries.
The World Bank Tokyo Development Learning Center (TDLC), in partnership with the Government of Japan, promotes knowledge sharing in urban development. Waste management is one of its key focus areas, and through programs such as the Technical Deep Dive (TDD), TDLC has facilitated the exchange of Japan’s experience and global knowledge. What a Waste 3.0 serves as an important foundation for such knowledge sharing and is expected to support policymaking and practical implementation. TDLC has also supported the research and dissemination of the What a Waste series.
