An ignored potential microplastic contamination of a typical waste glass recycling base
Summary
Researchers found that a typical waste glass recycling facility is an overlooked source of microplastic contamination, releasing plastic particles into the surrounding environment through its operations.
The service life of glass is limited, leading to a large amount of waste glass generated. The waste glass recycling base, as an essential municipal supporting facility of a sustainable city, has a significant impact on the surrounding ecological environment. This study conducted a comprehensive investigation and analysis of the potential pollutants in a large waste glass terminal recycling base. It was found that the waste glass treatment process may produce various pollutants such as particulate matter, heavy metals and so on, which might cause pollution to surrounding areas. Microplastics (MPs) of particulate matter, which were widely distribute in the study area, had high abundance and interact with heavy metals. Its release is related with different treatment processes. MPs were found in all sampling sites, a total of 59 polymer types were identified. The relationship between MPs and process characteristics is mainly reflected on the polymer types. The crushing and screening process are more likely to produce Acrylic, while the label-eliminate process is more likely to produce PMMA. It was estimated that the annual load of MPs in the waste glass recycling site is about 3.211 tons.

Mechanical recycling of plastic waste as a point source of microplastic pollution
Researchers found that mechanical recycling of plastic waste is a significant point source of microplastic pollution, releasing plastic fragments into wastewater during washing, shredding, and processing stages of the recycling chain.
Microplastics Identification in Plastic Recycling Facility: Removal Efficiencies of the Treatment Plants and Its Potential Release to the Environment
A plastic recycling facility in Indonesia was found to release significant quantities of microplastics into its wastewater, with nearly 500 particles per liter entering the treatment system and smaller fragments persisting even after treatment. The findings highlight that recycling operations — often considered part of the solution to plastic waste — can themselves be a meaningful source of microplastic pollution in local waterways.
Ignored microplastic sources from plastic bottle recycling
Researchers measured microplastic generation and fate in three facilities that recycle post-consumer PET bottles into flakes, finding microplastic concentrations in production wastewater ranging from 23 to 1,836 milligrams per liter. Overall wastewater removal ranged from 53% to 99.6% by mass, with the remainder concentrated in sludge, revealing plastic recycling facilities as a poorly recognized source of microplastic pollution.
The potential for a plastic recycling facility to release microplastic pollution and possible filtration remediation effectiveness
Researchers conducted a pilot study at a mixed plastics recycling facility in the UK and found that raw wash water contained extremely high concentrations of microplastic particles. They tested filtration systems and found that while most particles larger than 5 micrometers were successfully removed, smaller particles still passed through. The study highlights that recycling facilities themselves can be significant point sources of microplastic pollution to waterways if proper filtration is not in place.
Identifikasi Mikroplastik pada Air Sungai Akibat Limbah Pabrik Daur Ulang Plastik di Gresik dan Sidoarjo
This Indonesian study identified microplastics in the Kali Pelayaran River caused by wastewater discharged from a nearby plastic recycling factory. The findings show that recycling facilities — while beneficial for waste reduction — can themselves be a significant source of microplastic contamination in nearby waterways.
