Municipal solid waste (MSW) composting is rapidly growing globally as a sustainable approach to valorize the organic fraction of municipal (OFMSW) into compost for agricultural use. However, MSW use in agriculture threatened by physical contaminants, mainly plastics, glass, metals, and stones compost, exceeding legal thresholds some cases. This study comprehensively reviews literature on various contaminants focusing sources, occurrence, environmental implications, fate amended soils. The review shows that are highly heterogeneous depending origin, source separation, sorting sieving practices before after composting. Plastics most widely occurring abundant contaminant reaching up 15,300 mg/kg capable inputting 536 kg plastics/ha/year Glass, stones, metals also regularly occur 17.2%, 18.2%, 1.5% mass respectively. Repeated application contaminated increases accumulation soils, severely impacting soil's physical, chemical, biological performance. Synthetic plastics compost-amended soils tend have long residence time, slowly degrading releasing small-sized plastic particles their metabolites. Further, they may be transported from point biotic or abiotic agents, posing secondary pollution effects. Microplastics (MPs) significant emerging present detection challenges regulatory laxity marketing. strategies mitigate include proper biowaste improved separation screening composting, adherence monitoring adoption compostable biodegradable collection.

Strawberry, a globally popular crop whose fruit are known for their taste and health benefits, were used to evaluate the effects of polyethylene microplastics (PE-MPs) on plant physiology quality. Plants grown in 2-L pots with natural soil mixed PE-MPs at two concentrations (0.2% 0.02%; w/w) sizes (⌀ 35 125 µm). Plant physiological responses, root histochemical anatomical analyses as well biometric quality features conducted. subjected ⌀ μm/0.2% exhibited most severe terms CO2 assimilation due stomatal limitations, along highest level oxidative stress roots. Though no differences observed biomass, impact traits was MPs treatment resulting drop weight (–42%), soluble solid (–10%) anthocyanin contents (–25%). The smallest sized PE-MPs, adsorbed surface, impaired water status by damaging radical apparatus, which finally resulted alteration Further research is required determine if these alterations also occur other understand more deeply influence physio-chemistry. Anthropocene characterized an unprecedented surge plastic use, leading global microplastic (MP) proliferation terrestrial/aquatic environments. This study delves into topic MP interactions terrestrial plants, using spread (polyethylene [PE]) agricultural strawberry, strategic crop. Beyond impacts, this unveils potential strawberry PE-MP contamination soil. Herein demonstrated damage relation size concentration, providing scientific pieces evidence about risk exposure strawberries cultivated MP-polluted soil-system.
