En populär guide till hållbar städning och tvätt har uppdaterats med nya råd om mikroplaster och säkrare produkter.
Den uppdaterade artikeln från Earth911 belyser hur tvätt släpper ut miljontals plastfibrer i vattendrag vid varje tvätt. Den noterar att cirka 35 procent av mikroplasterna i haven kan härröra från tvätt av kläder.
A study from the University of Bonn shows that kitchen sponges shed microplastics during regular use. Emissions vary by sponge type, but water consumption drives most of the environmental impact from hand dishwashing.

Researchers at the University of Vienna have determined that land releases more than 20 times as many microplastic particles into the atmosphere as the oceans, challenging prior assumptions. Their study, published in Nature, used global measurements to correct overestimated emission models. The findings highlight land as the dominant source, though uncertainties persist.
Researchers at the University of Gothenburg found that feelings of disgust from dirty recycling stations lead to poorer waste sorting. An experiment showed clear improvements when stations received extra cleaning. The study was published in the Journal of Environmental Psychology.
