Introduction
The biomass content of solid recovered fuels is relevant for the evaluation of the impact of energy
production on greenhouse gas emission. Instrumental methods, wet chemical and manual procedures
are available for the calculation of the renewable energy fraction. Instrumental methods are based on
the determination of C content while manual procedures are based on separation of different fractions
by visual inspection. The wet chemical procedure differentiate biomass from non-biomass materials as
function of the acid dissolution behaviour.
The fraction of biomass is expressed:
— by mass;
— by energy content (gross or net calorific value);
— by carbon content.
This document is primarily intended for laboratories, producers, suppliers and purchasers of solid
recovered fuels, but is also useful for the authorities and inspection organizations.
