Future scenarios of global plastic waste generation and disposal
Open accessAbstract
The accumulation of mismanaged plastic waste (MPW) in the environment is a global growing concern. Knowing with precision where litter is generated is important to target priority areas for the implementation of mitigation policies. In this study, using country-level data on waste management combined with high-resolution distributions and long-term projections of population and the gross domestic product (GDP), we present projections of global MPW generation at ~1 km resolution from now to 2060. We estimated between 60 and 99 million metric tonnes (Mt) of MPW were produced globally in 2015. In a business-as-usual scenario, this figure could triple to 155–265 Mt y −1 by 2060. The future MPW load will continue to be disproportionately high in African and Asian continents even in the future years. However, we show that this growth in plastic waste can be reduced if developing economies significantly invest in waste management infrastructures as their GDP grows in the future and if efforts are made internationally to reduce the fraction of plastic in municipal solid waste. Using our projections, we also demonstrate that the majority of MPW (91%) are transported via watersheds larger than 100 km 2 suggesting that rivers are major pathways for plastic litter to the ocean.

TL;DR
This study projects global mismanaged plastic waste (MPW) at ~1 km resolution from 2015 to 2060 using country waste-management data with gridded population and GDP. It estimates 60–99 Mt of MPW in 2015, with business-as-usual growth to 155–265 Mt y⁻¹ by 2060 unless waste management improves and plastic demand is reduced.
Key findings
- Global MPW in 2015 was estimated at 60–99 Mt (midpoint 80 Mt), about 47% of global annual municipal plastic waste generation (midpoint 181 Mt for n = 188 countries).
- Under business-as-usual scenario A, MPW could nearly triple to 213 (155–265) Mt y⁻¹ by 2060; under scenario B, with waste management improving as GDP grows, global MPW could peak before 2020 and fall to 50 (22–94) Mt y⁻¹ by 2060; under scenario C, capping plastic in municipal solid waste at 10% by 2020 and 5% by 2040 plus scenario B improvements, MPW could fall below 25 Mt y⁻¹ before 2060, with 74% generated in Africa and 21% in Asia.
- 91% of MPW was generated inside watersheds larger than 100 km², suggesting rivers are major pathways to the ocean; 5% was discarded directly near the coastline (<10 km²) and 4% at 10–100 km², with over a quarter in 14 continental rivers.
- In 2015, Asia released 52 (42–58) Mt of MPW, 65% of the global total; Africa had the highest unsound disposal rate at 88.5%, producing 17 (10–20) Mt. Top countries were China (17.2 Mt y⁻¹), India (14.4 Mt y⁻¹), and the Philippines (4.52 Mt y⁻¹); Manila was the largest urban centre at 0.81 Mt y⁻¹.
Methods
- Country-level Waste Atlas data on per capita municipal solid waste generation, mismanaged fraction, and plastic fraction were combined with 30 × 30 arc-second (~1 km) Landscan 2014 population density and UNEP/DEWA/GRID-Geneva GDP distributions; future projections used UN, IMF, and OECD population and GDP projections to 2060.
- Empirical relationships estimated missing values: per capita MSW generation vs per capita GDP (a = 11.434, b = 0.3433, n = 160), mismanaged fraction vs per capita GDP (e = −3.13 × 10⁻³, f = 104, n = 95), and a global average plastic fraction of 10.9% ± 4.5% (n = 105).
- Three scenarios were modeled: A, business-as-usual waste management; B, mismanaged fraction declining with GDP growth; C, scenario B plus plastic fraction capped at 10% by 2020 and 5% by 2040. Watershed analysis used HydroSHEDS boundaries.
Limitations
- The paper states that waste data were reported at national level and may vary within countries; confidence intervals include uncertainties in per capita MSW generation, plastic proportion, and mismanaged fraction. Projections neglect subnational population redistribution, plastic waste exports/imports, exceptional economic or societal events, and changes in technology, product design, or behavior.
- The paper also notes that population density was assumed to grow at the same rate as the national average, which may bias projections, and that rural exodus could further reinforce urban waste production.
- Evident from the text: the Waste Atlas data are non-exhaustive (n = 160 for MSW generation, n = 95 for unsound disposal, n = 105 for plastic proportion), and the model assumes per capita solid waste generation scales with GDP within a country and that relative spatial distributions remain constant over time.

The authors state this as an assumption.
The proportion of plastic in solid waste (p) is the same for all unmanaged waste including litter.
“Value of p is assumed to be the same for all unmanaged waste including litter.”
The authors state this as an assumption.
Per capita solid waste generation scales with GDP inside a country.
“An important model assumption here, is that per capita solid waste generation scales with GDP inside a country.”
The authors state this as an assumption.
For future projections, the relative spatial distribution of population and GDP within countries remains the same over time; possible migration and sub-national variations are neglected.
“we neglected the possible migration of population or variations in domestic product inside countries for our future projections as we considered the relative distribution to remain the same over time.”
The authors state this as an assumption.
In scenario A, the mismanaged fraction reported by Waste Atlas (2016) is maintained into future years.
“For scenario A, we considered the case of business-as-usual where the mismanaged fraction reported by Waste Atlas (2016) were maintained into the future years”
The authors state this as an assumption.
In scenario B, waste management efforts improve with increased investment in infrastructure as economies grow.
“In scenario B, we assumed waste management efforts will improve with increased investment in infrastructure as the economies in individual countries grow in the future.”
The authors state this as an assumption.
In scenario C, the same assumptions as scenario B hold and the fraction of plastic in solid waste is capped to 10% by 2020 and 5% by 2040.
“Finally, in scenario C, we used the same assumption as in scenario B and further reduced the input of individual countries by capping the fraction p of plastic in solid waste to 10% by 2020 and to 5% by 2040.”
The authors state this as an assumption.
As the economy grows, waste management infrastructure improves.
“i.e., as the economy grows, waste management infrastructure improves”
The authors state this as an assumption.
Waste management data is mainly reported for urban centres and levels of per capita use may not be representative of rural areas.
“Waste management data is mainly reported for urban centres and we trust that levels of per capita use may not be representative of rural areas.”
The authors state this as an assumption.
Waste generation in small watersheds in arid or mountainous unpopulated regions is very small and can be neglected from inland inputs.
“As the waste generation in these areas is very small since they are generally unpopulated, we neglected the contribution of these regions from inland inputs.”
The authors state this as an assumption.
Population density grows at the same rate as the national average.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
