The dynamic expansion of the Agricultural Plastics (AP) use has allowed for improved agricultural products quality, yields, and enhanced sustainability along with multiple benefits for the Agrifood sector. The present work investigates the relationship of AP characteristics, use and End-of-Life (EoL) practices with degradation and potential generation of micro-, nanoparticles (MNP) in soil. The composition, functionalities, and degradation behaviour of the contemporary conventional and biodegradable AP categories are systematically analysed. Their market dynamics are briefly presented. The risk and the conditions for the AP potential role in soil pollution and possible MNP generation are analysed based on a qualitative risk assessment approach. AP are classified from high to low-risk products with respect to their probability for soil contamination by MNP based on worst-best scenarios. Proposed alternative sustainable solutions to eliminate the risks are briefly presented for each AP category. Characteristic quantitative estimations of soil pollution by MNP generated by AP are presented for selected case studies reported in the literature. The significance of various indirect sources of agricultural soil pollution by MNP is analysed allowing for appropriate risk mitigation strategies and policies to be designed and implemented.

A review of agricultural plastic waste generation and consolidation in Europe is presented. A detailed geographical mapping of the agricultural plastic use and waste generation in Europe was conducted focusing on areas of high concentration of agricultural plastics. Quantitative data and analysis of the agricultural plastic waste generation by category, geographical distribution and compositional range, and physical characteristics of the agricultural plastic waste per use and the temporal distribution of the waste generation are presented. Data were collected and cross-checked from a variety of sources, including European, national and regional services and organizations, local agronomists, retailers and farmers, importers and converters. Missing data were estimated indirectly based on the recorded cultivated areas and the characteristics of the agricultural plastics commonly used in the particular regions. The temporal distribution, the composition and physical characteristics of the agricultural plastic waste streams were mapped by category and by application. This study represents the first systematic effort to map and analyse agricultural plastic waste generation and consolidation in Europe.
