Gaseous products and particulate matter emissions of biomass residential boiler fired with spent coffee grounds pellets

- Agropellets produced from spent coffee grounds or blended with pine sawdust.
- Agropellets physicochemical characteristics and energy contents were determined.
- Combustion performances, gaseous and particulate emissions of pellets boiler.
- Although an interesting energy content, pure SCG is not adapted for pellets boiler.
- Sawdust/SCG blend is an attractive alternative fuel to reach NF agro-pellets label.
