This report summarise the work made in order to understand the potential waste biomass in Europe and to select among them the waste biomass most suitable for gasification considering availability on significant scale (t/year), good technical (physical (low water content and high bulk density) and chemical (high Caloric Value, high volatile substances, low ash, high Carbon to Nitrogen ratio, low Chlorine and Sulphur content)) and economic (selling cost at production site plus transport cost) characteristics and to characterise (proximate and ultimate analysis, elements determinations, ignition and burn-out temperatures, ashes characterization) the waste biomass selected as representative. In particular, this report, shows the work undertaken under the Task 2.1, Biomass supply led by USGM and the Task 2.2, Feedstock characterisation led by ENEA of the WP2, Gasification & conditioning tests, of the BLAZE project by USGM (5 MM), ENEA (4 MM), EUBIA (4 MM) and UNIVAQ (1MM).

This report is composed of the following parts:

  • Chapter 2, Introduction, quotes a brief introduction on biomass and gasification definitions and related characteristics;
  • Chapter 3, Biomass specifications for gasification, quotes a short description of the main biomass specifications for gasification;
  • Chapter 4, Biomass feedstock, describes the biomass availability and cost on the EU 28 countries by groups and subgroups and regions;
  • Chapter 5, CHP potential, summarises CHP plants widespread over EU in the capacity range from 25-100 kWe (small scale) to 0.1-5MWe (medium scale);
  • Chapter 6, Supply chain cost, describes the supply cost for different biomass category;
  • Chapter 7, Biomass selection, selects 10 samples and 5 mixtures representative of the most available European biomass species that will be characterized in chapter 8 and gasified in Task 2.3 (D2.2) in order to asses syngas composition and contaminants that affect SOFC and related gasifier parameters and bed materials to reduce SOFC hazardous effects;
  • Chapter 8, Biomass characterization, quotes the chemical and physical characterization of the waste biomass selected, illustrating the protocols used, the proximate/preliminary and ultimate/elemental analysis, the elements determinations, ignition and burn-out temperatures, ash melting behaviour and thermophysical characterization;
  • Chapter 9, Conclusions, quotes a comprehensive discussion and outlook;
  • Chapter 10, References, quotes the references of all the report.

At the end there are 15 pages that quotes, as Annex I and II, the experimental results on ignition/burn out temperatures and TGA of ashes.
