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.

Next UK prime minister must ban microplastics, says drainage group

Envirotec Magazine

The UK’s next prime minister should ban manufacturers from intentionally adding microplastics to consumer or professional use products, according to a new environmental campaign from the drainage experts at Lanes Group plc. Microplastic particles measure less than 5mm and are incorporated into a wide variety of consumer products.

Tannins: A possible answer to microplastic pollution?

Envirotec Magazine

Scientists at UBC’s BioProducts Institute find that if you add tannins to a layer of wood dust, you can create a filter that traps virtually all microplastic particles present in water, according to recently reported research. per cent of plastic particles in a column of water, depending on plastic type. per cent to 99.9

Using microbes to remove microplastics

Envirotec Magazine

Researchers at Hong Kong Polytechnic University have developed a seemingly new technique to trap and recover microplastics. The method uses bacterial biofilms, a sticky substance created by micro-organisms, to trap microplastic particles. In bioreactors, this makes the microplastics more convenient to collect, according to Liu.

Brazilian group presents novel method of analyzing microplastic pollution

Envirotec Magazine

The last decade has seen some progress with studying plastic pollution, but there are still significant challenges, such as a lack of comparability of reported results, especially when it comes to microplastic particles. River landscape in Pantanal, Brazil. We measure particle size in all samples.

LDIR microplastic analysis used in the Indian Ocean

Envirotec Magazine

Methods for the analysis of microplastic particles in a sample (of water) are beset by challenges such as high error rates and a high time requirement. The chemical characterization of the microplastic particles is based on their absorption of infrared light. Near-surface analysis.
