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.
NOTE In 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.
