Differenciating between material fractions in refuse-derived fuels (RDF) is relevant to determining the climate relevance of RDF (fractions biomass and fossil matter). This differentiation associated with analytical challenges. A method was applied using balance equations, which contain elemental composition (C, H, N, S, O) sought for fractions. For first time this so-called adapted Balance Met...
