As one of the flagship amendments to the Plastic Waste Management (PWM) Rules, 2021, the pan-Indian ban on a group of single-use plastic products (SUPPs) introduced in mid-2022 provided a departure point towards more progressive plastic waste legislation. The amendments have mostly been welcomed, yet challenges persist to facilitate its implementation, assess potential environmental impacts of alternative materials, and socio-economic concerns raised by various stakeholders. Considering the recent amendments to the PWM Rules, we critically engage with and highlight key considerations and prevailing challenges with regards to phasing out SUPPs. We argue that to shape sustainable solutions that reduce plastic pollution, uncertainties related to the environmental fate of SUPP alternatives need to be better understood, whilst recognising and accounting for broader socio-economic impacts of SUPP bans, including industry concerns, impacts on socio-economically disadvantaged communities, and the informal recycling sector. A stronger knowledge base on these aspects can mitigate negative social and environmental externalities, including potentially harmful consequences of ambitious plastic pollution reduction measures.
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[…]
