BAS CEN/TS 15440:2010

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.
