INFLUENCE OF Eucalyptus WOOD ADDITION TO URBAN WOOD WASTE DURING COMBUSTION
ABSTRACT This research analyzed the effect of the addition of E. grandis x E. urophylla wood to the wood waste of urban origin (WWU) as a strategy for energy generation. The WWU was collected in transshipment and from a sorting company of civil construction waste in the city of Piracicaba, SP. The wood of eucalyptus was obtained from a 7-year old plantation. Five treatments with proportions (%) of WWU and eucalyptus wood were analyzed: T1 = 100/0, T2 = 75/25, T3 = 50/50, T4 = 25/75 and T5 = 0/100. 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 hierarchical clusters analysis (HCA). The higher content of extractives, holocellulose, volatile materials, low ash content values, rate of mineral contaminants and high performance for combustion test were observed only for the treatment having exclusively eucalyptus wood (T5). However, the addition of eucalyptus wood in the WWU allowed for the increase of the ICOM of these materials. In this way, the T3 treatment presents as the most recommended for energetic use.
