This Technical Specification specifies two normative methods and one informative method for the determination of the biodegradable/biogenic fraction in solid recovered fuel. The methods are the selective dissolution in sulphuric acid, the manual sorting method and the informative reductionistic method. The methods estimate the biodegradable/biogenic content of solid recovered fuels by determination of the biomass content.This Technical Specification is not applicable to:-pure fractions of waste, products and by-products classified as CO2-neutral biomass according to Annex G;-charcoal, peat and solid fossil fuels like hard coal, coke, brown coal and lignite and to mixtures of these and solid recovered fuels;-solid recovered fuels that contain more than 10 % of natural and/or synthetic rubber residues;-solid recovered fuels that contain a combination of more than 5 % by weight of:-nylon, polyurethane or other polymers containing molecular amino groups;-biodegradable plastics of fossil origin;-solid recovered fuels that contain a combination of more than 5 % by weight of:-wool or viscose;-non-biodegradable plastics of biogenic origin;-oil or fat present as a constituent of biomass.NOTEIn typical municipal and assimilated waste the content of nylon, polyurethane, biodegradable plastics of fossil origin, wool, viscose, non-biodegradable plastics of biogenic origin and oil/fat present is rather small and the error is negligible.
