Unveiling Microplastic Removal and Characteristics in Wastewater from Two Municipal Wastewater Treatment Facilities in Indonesia
Two Indonesian municipal wastewater treatment plants — one advanced, one using simple ponds — both achieved roughly 90% microplastic removal, bringing influent concentrations of around 16 particles per liter down to about 1.5 particles per liter in treated effluent. Despite high removal rates, the remaining microplastics (predominantly PP, PE, PET, and polystyrene fibers and fragments) still discharge into receiving waters continuously, highlighting the need for improved treatment technologies to protect Indonesian aquatic ecosystems.
Distribution and occurrence of microplastics in wastewater treatment plants
Researchers investigated microplastic distribution in three industrial wastewater treatment plants in Vietnam, finding average removal efficiencies of only 21-26%, with billions of microplastic particles discharged daily into receiving waters from the largest plant.
Plastic waste management in recycling facilities: Intentionally generated MPs as an emerging contaminant
Researchers characterized microplastic pollution in wastewater from four plastic recycling facilities in Turkey, finding that the recycling process itself generates significant quantities of microplastics. The dominant polymers detected were polyethylene and polypropylene, matching the materials being processed. The study suggests that plastic recycling facilities are an overlooked source of microplastic contamination and that better wastewater treatment at these sites is needed.
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.
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.
Occurrence and Characteristics of Microplastics in a Wastewater Treatment Plant
Researchers sampled the inflow, outflow, and sludge of a Chinese wastewater treatment plant, finding up to 44 microplastic particles per liter in incoming water — mostly polyester fibers. The plant removed about 96% of microplastics, but the remaining fraction was still discharged into receiving waterways.
Abundance and removal of microplastics in sewerage treatment plants: A case study of Ujung Menteng Flat House
Researchers evaluated microplastic characteristics and removal efficiency at the Ujung Menteng Flat House Sewerage Treatment Plant in Indonesia, sampling from influent, activated sludge, and effluent to assess how effectively existing wastewater infrastructure — not designed for microplastic removal — reduces contamination.
Distribution of Microplastics in Domestic Wastewater and Microplastics Removal Potential in Wastewater Treatment Plants
Researchers examined the distribution of microplastics in domestic wastewater in Indonesia and assessed the microplastic removal potential of wastewater treatment plants, using digestion, vacuum filtration, and microscopy to identify microplastics by concentration, shape, size, and color across treatment stages.

Abundance, characteristics, fate, and removal of microplastics during municipal wastewater treatment plant in the west of Iran: the case of Kermanshah city
A three-month study of a conventional activated sludge wastewater treatment plant in Kermanshah, Iran found that while the facility removed about 64% of incoming microplastics, large quantities still passed through into the effluent — making the plant a net source of microplastic pollution to the aquatic environment. Fibers dominated incoming samples while fragments were more prevalent in the treated effluent, and polyethylene was the most common polymer detected throughout.
Microplastics in wastewater and sludge from centralized industrial wastewater treatment plants in Ho Chi Minh City, Vietnam
Researchers measured microplastic levels in two industrial wastewater treatment plants in Ho Chi Minh City, Vietnam, finding concentrations up to 40 particles per liter in incoming water and up to 92 particles per gram in sludge, with fibers being the most common type. Despite high removal rates, the plants still discharged 1.7 million microplastic particles per day, highlighting the limits of current treatment infrastructure.
Global discharge of microplastics from mechanical recycling of plastic waste
Researchers found that the mechanical recycling process for plastics actually generates significant amounts of new microplastics, with global emissions from recycling projected to grow from 0.017 million tonnes in 2000 to 0.749 million tonnes by 2060. While recycling accounted for about 3.1% of total microplastic emissions in 2017, this share could grow as recycling increases. The study highlights an important paradox: efforts to reduce plastic waste through recycling can themselves contribute to microplastic pollution unless wastewater treatment at recycling facilities is improved.
