Almost a quarter of the plastic produced in Europe still ends up in landfills. In addition to the loss of valuable resources, this leads to the generation and accumulation of microplastics in landfills. The microplastics abundance in the refuse and their spatial distribution in the landfill body have not been practically studied. In the current work, changes in the abundance and characteristics of microplastics in landfill refuse from 3 age sections of the Lapės regional landfill, Lithuania, to a depth of 10–20 m were studied. A microplastics abundance of up to 55 particles/g or 52.8 g/kg was found. The lowest microplastics abundance was found in the old section, while the highest in the young (numerical) and the middle-aged (mass) sections. Moreover, microplastics abundance increased with the age of landfilled waste and depth, which may reflect the fragmentation of microplastics and their transport. Polyethylene and polypropylene were the dominant polymer types in all sections, while films were the dominant shape. The carbonyl index of PE microplastics was calculated to monitor microplastics oxidation. The analysis showed an increase of carbonyl index with landfill depth and landfill age, proving the intensive degradation of microplastics. Thus, landfills are large reservoirs of microplastics and their potential sources.

“…The average concentration of microplastics ranges from 4958 ± 439 particles/kg at a 0-1.5 m depth to 34,917 ± 1922 particles/kg at a 6-7.5 m depth. The abundance of microplastics in soil [41,42], green and food compost [43], and stabilized organic output from MBT [44] is usually lower than the abundance found in landfill bodies.…”

Landfills pose global challenges, notably in terms of greenhouse gas (GHG) emissions, pollution release, and extensive land occupation. The transformative practice of landfill mining has redefined these sites as valuable resource reservoirs. The fine fraction (FF), often constituting the majority of excavated waste, is currently underutilized but holds the potential for biocover construction to mitigate methane emissions. This study comprehensively analyzes the FF from the Kuršenai landfill, collecting samples from various depths, reaching up to 10.5 m. The most suitable layers for biocover construction were determined based on basic physical and chemical parameters, along with the concentration of heavy metals and microplastics. The findings unveil significant parameter variations across different depths. Moderate–high correlations (ranging from 0.5 to 0.84) between several parameters were observed. The layer at a depth of 4.5–6 m emerged as the most suitable for biocover construction. However, this layer is characterized by elevated microplastic concentrations (30,208 ± 273 particles/kg), posing a challenge for its use in biocovers as microplastics can be released into the environment during FF extraction and biocover construction. Additionally, microplastics become finer with depth, increasing the associated risks. Therefore, a balanced approach considering material properties and pollution concentrations is vital for sustainable waste management practices.

“…17,18 MPs could be stable in aquatic environments for a long time owing to special characteristics (light weight, small particle sizes, strong hydrophobicity, variable density and large specic surface area). [19][20][21] Moreover, owing to these unique properties, MPs can sorb numerous pollutants (e.g., heavy metals [22][23][24] and organic pollutants 25,26 ) from the surrounding aquatic environments and act as carriers owing to their long-term transport in aquatic ecosystems, thereby resulting in even more signicant hazards to organisms. 27 MPs in actual environments experience aging under the inuence of various factors, such as light and microorganisms, which may change the morphology and structure of MPs, thus affecting their environmental behaviors and interactions with pollutants.…”
