This section presents the GWMO global and regional waste management data compiled in collaboration with the International Solid Waste Association (ISWA). The dataset provides macro-level analytics tracking municipal solid waste volumes across regions from 2023 through projected figures to 2050, documenting the anticipated increase from 2.1 billion tonnes to 3.8 billion tonnes globally.
The global outlook analytics incorporate quantitative assessments of waste management costs across multiple scenarios, utilizing life cycle assessment methodologies to calculate both direct operational expenses (USD 252 billion) and externalized costs related to environmental degradation, public health impacts, and climate change contributions (bringing the total to USD 361 billion).
The regional comparative analytics enable assessment between current waste management approaches and alternative scenarios, including improved management practices (USD 270.2 billion) and circular economy implementation (net annual gain of USD 108.5 billion). Performance metrics for global and regional analysis include aggregated waste generation trends, comparative management costs, environmental impact indicators, and intervention effectiveness measurements across geographic regions.
This global outlook data supports evidence-based international policy development, cross-regional investment planning, and strategic decision-making for multinational development banks, international organizations, and governmental bodies involved in waste management infrastructure and regulatory frameworks at the regional and global levels.
Principal Evidences
Increased waste generation strains
Existing waste management systems and depletes resources for proper waste processing
Rising waste generation
Underscores the urgency for sustainable waste management practices globally
Promote circular economy
Enhancing recycling and reuse strategies to reduce waste generation
Principal Indicators
Principal Evidences
Rapid urbanisation
Leads to excessive waste generation that overwhelms urban waste management infrastructure
Rising waste generation
Underscores the urgency for sustainable waste management practices globally
Implement targeted policies
For urban waste management, including incentives for waste reduction and recycling
Principal Indicators
Principal Evidences
Policy frameworks
Extended producer responsibility and landfill taxes significantly improve recycling performance
Economic incentives
Deposit return schemes and pay-as-you-throw systems have increased recycling rates by up to 40%
Consumer behavior
Awareness campaigns and accessible recycling infrastructure correlate with higher participation rates
Principal Indicators
Principal Evidences
Infrastructure gaps
Limited funding and technical capacity prevent development of sanitary landfills
Health impacts
Communities near uncontrolled dumpsites face increased rates of respiratory and waterborne diseases
Technology transfer
Implementing basic landfill management practices could reduce environmental impact by 60%
Principal Indicators
Principal Evidences
River systems
Ten major river systems account for 90% of plastic waste entering oceans from land-based sources
Waste management correlations
Countries with inadequate waste management infrastructure contribute disproportionately to marine plastic pollution
Microplastic contamination
Microplastics have been detected in 94% of water samples from major oceans, affecting marine food chains
Principal Indicators
Principal Evidences
Income level correlation
Higher-income regions produce more paper, plastic, and metal waste; lower-income regions generate more organic waste
Seasonal variations
Waste composition fluctuates seasonally, with organic content increasing by up to 15% during growing seasons
Treatment optimization
Understanding waste composition enables targeted strategies like composting for organic-rich waste streams
Principal Indicators
Principal Evidences
Methane dominance
Methane constitutes 60% of waste sector emissions, with a global warming potential 28 times that of CO2
Landfill gas capture
Implementing landfill gas capture systems can reduce methane emissions by up to 85% while generating energy
Food waste reduction
Halving food waste could reduce waste sector emissions by 15% while addressing food security challenges
Principal Indicators
Principal Evidences
Rapid growth rate
E-waste is the fastest-growing domestic waste stream, increasing at 3-5% annually due to shorter product lifecycles
Resource value
E-waste contains precious metals at concentrations 40-50 times higher than naturally occurring ore deposits
Policy effectiveness
Countries with extended producer responsibility legislation achieve recycling rates up to 40% higher
Principal Indicators
Principal Evidences
Informal sector significance
Informal waste workers collect up to 60% of recyclables in many developing countries, often working in hazardous conditions
Economic multipliers
Each job in waste management and recycling creates an additional 1.5-2 jobs in the broader economy
Formalization benefits
Integrating informal workers into formal waste systems can improve incomes by 30% while improving working conditions
Principal Indicators
Principal Evidences
Funding models
Mixed public-private funding approaches have increased waste management budgets by up to 40% in transitioning economies
Cost-benefit ratio
Each dollar invested in waste management yields $4-5 in avoided health and environmental costs, plus economic benefits
Budget allocation gaps
Even where waste management is prioritized, operation and maintenance funding often remains insufficient for long-term sustainability
