Abstract

This research analyzed the effect of the addition of Eucalyptus sp wood to the wood waste of urban origin (WWU) as a strategy for energy generation.  The WWU was collected in transshipment and sorting company of Civil Construction Waste in the city of Piracicaba-SP and the wood of Eucalyptus sp was obtained from a 7-year old plantation. Five treatments with proportions of WWU and Eucalyptus sp wood were analyzed: T1 = 1/0, T2 = 3/1, T3 = 1/1, T4 = 1/3 e T5 = 0/1. The treatments had the physical, chemical, immediate characteristics, mineral contaminants rate, and combustion test (ICOM) analyzed. The data were analyzed through the study of variance, correlations, and multivariate similarity in a Manhattan plot. The higher content extractives, holocellulose, volatile materials, low ash content values, contaminants rate and high performance for combustion test were observed only for the treatment having exclusively Eucalyptus sp wood (T5). However, the addition of wood in the WWU allowed for the increase of the ICOM of these materials. The multivariate analysis of the cluster allowed for the grouping of the treatments observing similarities between the groups of biomass with the obtained dendrogram.
