This section presents comprehensive country-level waste management data compiled in collaboration with the International Solid Waste Association (ISWA). The country dataset tracks municipal solid waste volumes across nations from 2023 through projected figures to 2050, documenting the anticipated increase from 2.1 billion tonnes to 3.8 billion tonnes globally. Each country profile within this dataset includes quantitative assessments of national waste management costs across multiple scenarios, utilizing life cycle assessment methodologies to calculate both direct operational expenses and externalized costs related to environmental degradation, public health impacts, and climate change contributions within specific national contexts. The country-specific analytics enable comparative analysis between current national waste management approaches and alternative scenarios, including improved management practices and circular economy implementation. Performance metrics for each country include waste generation rates per capita, management costs as percentage of GDP, environmental impact indicators, and intervention effectiveness measurements. This country data supports evidence-based national policy development, investment planning, and strategic decision-making for governments, municipalities, and organizations involved in waste management infrastructure and regulatory frameworks at the national level.
