In this paper, research was conducted to identify the main research areas while evaluating alternatives to agricultural plastics to promote more sustainable food production based on the circular economy. A bibliometric analysis was carried out in this study, where a sample of 2043 papers was analyzed. Results from the analyses reveal the growing interest of the scientific community in this field of research while establishing the need for investing in biopolymers that can replace plastic in cultivation techniques and packaging, which are the main contributors to microplastic pollutants. Microorganisms that synthesise bioplastics and biodegradable plastics are seen as feasible alternatives that, despite their drawbacks, have the potential to reduce the environmental burden of traditional plastics, thereby contributing to improving their life cycle. The implementation of the alternatives that stand out in this research can help to enhance the accomplishment of current and future environmental objectives and strategies furthered by the EU.
The current study examines the contamination of microplastics in three greenhouse types: abandoned, normal, and simple. The findings revealed that the abundance of microplastics was found to be the highest in the abandoned greenhouse, followed by the normal greenhouse and simple greenhouse. The mean abundance of microplastic organic fertilizer and irrigation water was also high.[…]
The study examines the distribution of residual film after eight years of film mulching in mid-April 2018. Results from the study revealed that eight years of mulching significantly increased the quantity of agricultural mulch film residues in the soil. The size of residual film fragments was found to vary from 0.25 cm2 to 109 cm2,[…]
A study in Yuanmou County, Yunnan Province, investigated microplastic pollution in different land uses, including facility farmland, traditional farmland, orchard, grassland, and woodland. Results showed a significant difference in microplastic abundance and characteristics between different land use types. Facility farmlands, traditional farmlands, and orchard lands had higher microplastic abundance than grasslands and woodlands. The main[…]
The study analysed 225 soil samples from maize planting zones in northern China, revealing that long-term plastic film mulching increases microplastic pollution in agricultural soils. The abundance of microplastics was significantly higher in mulched soils (754 ± 477 items kg-1) than in non-mulched soils (376 ± 149 items kg-1). The length of time with film[…]
The study examined the relative abundances and morphological distributions of microplastics (MPs) in water, sediments, and farmland soils in the Caohai Lake region. The estuary in the study area was considered a potential sink for MP transportation. Transparent and black MPs accounted for a large proportion of MPs in the five environments, with possible sources[…]
