Standards Development
This document specifies a laboratory method for the extraction of microplastics from compost matrices originating from industrial or home composting. The method outlines various extraction steps assuring polymer stability, and high recovery rate. This extraction process separates microplastics from the compost matrix that can be further analysed either by number-based or by mass-based techniques.
The method is applicable for microplastics up to 1 mm in size.
The method is applicable for microplastics with densities lower than 1,4 g/cm3.
This document will not specify downstream detection methods for the identification and quantification.
The method in this document has not been validated for microplastic extraction from other matrices, except for composts.
