Utilizing Dynamic Probabilistic Material Flow Analysis (DPMFA) coupled to a release model, we comprehensively tracked emissions of macro- and microplastics in Switzerland from 1950 to 2022, covering 35 product categories and 183 release pathways for seven polymers (LDPE, HDPE, PP, PS, EPS, PVC, PET). The plastic usage exhibited a “Peak Plastic” around the year 2010 with a subsequent decrease in per capita use of plastics from 120±5 to 107±5 kg/cap in 2022. Over the considered timeframe, 27±1 kg/cap of macroplastics and 4 ± 1 kg/cap of microplastics were released to the environment, with the most substantial contributions coming from LDPE and PET. The overall emission factor was 0.66±0.07 % for macroplastics and 0.010±0.01 % for microplastics. The model can provide a crucial framework for crafting targeted interventions toward sustainable plastic lifecycle management.Keywords: Plastic; MFA; Release; Dynamic; Microplastics

Using dynamic release modeling to predict historic and current macro- and microplastic releases
AI summary Read the abstract
Using a dynamic material flow model, researchers tracked how macro- and microplastics have been released to the Swiss environment from 1950 to 2022 across 35 product categories and 183 release pathways. The model found that per-capita plastic use peaked around 2010 and has since declined slightly, but over the full period roughly 27 kg of macroplastics and 4 kg of microplastics per person were released to the environment — providing a quantitative baseline for designing more targeted reduction policies.
Advancing plastic release modeling: updating emission flows and extending the system boundary from Switzerland to Europe
AI summary Read the abstract
Researchers updated a Swiss plastic release model and extended its geographic scope to the European scale by integrating improved emission pathway data from recent studies and incorporating previously excluded plastic release sources. The revised model offers higher-resolution estimates of plastic flows across European countries, enabling better-informed policy decisions on reducing plastic emissions to the environment.

A proxy-based approach to predict spatially resolved emissions of macro- and microplastic to the environment
AI summary Read the abstract
Using land-use statistics, traffic data, and wastewater infrastructure as proxies, researchers created high-resolution maps of microplastic and macroplastic emissions across Switzerland at the regional level. The approach reveals that plastic pollution is concentrated near urban and high-traffic areas but varies substantially by polymer type and emission source.
