What is ISO 21644- Methods for the determination of biomass content about?
ISO 21644 specifies three methods for the determination of the biomass content in solid recovered fuels: the 14C content method, the selective dissolution, and the manual sorting methods.
The biomass content gives an estimation of the content of the biogenic fraction in solid recovered fuel.
Who is ISO 21644 - Methods for the determination of biomass content for?
ISO 21644 on the methods for the determination of biomass content is beneficial for:
- Waste recycle management
- Manufacturing plant
- People who work for magnetic and refining separation
- Biorefinery researchers
- Biomass organizations
Why should you use ISO 21644 - Methods for the determination of biomass content?
The biomass content of solid recovered fuels is relevant for the evaluation of the impact of energy production on greenhouse gas emissions.
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 14C content while manual procedures are based on the separation of different fractions by visual inspection. The wet chemical procedure differentiates biomass from non-biomass materials as a 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
ISO 21644 is primarily intended for laboratories, producers, suppliers, and purchasers of solid recovered fuels, but is also useful for the authorities and inspection organizations.
Overall, ISO 21644 is helpful as it provides guidance to the user for the determination of biomass content by sampling, applicable methods, test reports.
