Preparation of refuse derived fuel (RDF) sample was explored.
Preparation methods were related to the results of thermo-gravimetric analysis (TGA).
Analysis of 10 mg RDF samples by TGA was repeatable when samples were prepared by cryogenic milling.
With cryogenic milling, TGA could compete with AMS for determining RDF renewability.
With cryogenic milling, TGA could compete with selective dissolution for RDF renewability analysis.
