Study maps human uptake of microplastics across 109 countries

Envirotec Magazine

Indonesians eat more microplastics per month than any other country, said the study, with most of it coming from seafood (image credit: raulbaldean / Shutterstock.com). That is a 59-fold increase in daily microplastic consumption from 1990 to 2018, the date range used for the models. grams per month, while the lowest is Paraguay at 0.85

Shredding is unappreciated microplastics source

Envirotec Magazine

Line for washing shredded PET plastic at a recycling facility. Australian researchers have identified a new, or previously overlooked, culprit in the release of microplastics into the environment: The shredding process used to recycle plastics. They subsequently discussed this in a commentary published in Science.

Pathogens which cling to microplastics may survive wastewater treatment

Envirotec Magazine

Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a new study appearing in the open-access journal PLOS ONE. Wastewater treatment plants are designed to remove contaminants from wastewater, but microplastics persist and can become colonized by a sticky microbial biofilm.

How old is that microplastic? A new way to estimate the age of microplastics in the upper ocean

Envirotec Magazine

Researchers have developed a new way to estimate the age of microplastics found in the upper oceans. The method involves a combination of analyzing plastic oxidation levels with environmental factors such as UV exposure and ambient temperature. As plastic waste is exposed to the elements they eventually break down and fragment.

Microplastic pollution in landfill leachate: A few drips of progress?

Envirotec Magazine

The microplastic pollution that turns up in landfill leachate has received much less attention than the stuff appearing in wastewater, and there seem to be far fewer studies exploring it. According to the OECD, in 2019, 50% of the world’s plastic waste was landfilled, 19% was incinerated, 9% was recycled and 22% was mismanaged.

Microplastics: Six surprising everyday things that contain and release them

Envirotec Magazine

Microplastics have become so widespread that they have been discovered in fresh Antarctic snow. Something as seemingly innocent as Halloween decorations or gum can be a source, says Sulacpac, a producer of bio-based alternatives for conventional plastics. However, typical plastic waste isn’t the only source of microplastics.

Washing machine filter captures microplastic without the need for disposables

Envirotec Magazine

Bristol based microplastic technology company Matter is launching Gulp, “the first sustainable, long-lasting washing machine microfibre filter” on Kickstarter from 11 October. and recycling of microplastics, and says it is focused on “cradle-to-cradle solutions”, with a mission to stop microplastic pollution at source.
