In developing countries’ socio-environmental background, fossil fuel use is evolving at the same time as deforestation, resulting in desertification and global warming. There is an urgent need to find alternative sustainable and environmentally friendly sources such as biomass briquettes. This study aims to analyse the effect of densification temperature on characteristics of biomass briquettes produced from rice husks. The densification temperatures applied to each production run varied from 0 to 350°C with an increment of 50°C in a heating screw press. Physical and proximal analysis of briquettes produced at each stage of temperature is done in order to determine bulk density, moisture content, Ash content, volatile matter according to NF standard. A statistical analysis was applied in order model the relationship between briquettes’ characteristics and densification temperature. Interpretation of correlation coefficients (0,98) shows that there is a strong correlation between densification temperature and briquette density. As temperature increases, density also increases. However, the correlation (r = 0,44) between densification temperature and ash content is very low, and there is no significant impact.
