Recent progress in Life Cycle Impact Assessment highlighted the need to assess the loss of resources' functional value when assessing the life cycle impacts of resource depletion. To be able to assess the loss of functional value of resources due to scarcity and depletion, there is a need to assess the potential substitutions among different resources to fulfill the same functionality. In this sense, the main objective of this study is the development of a method for obtaining a substitution index (SI) for wood, quantifying to what extent the wood is substitutable by other available resources for the different functions it can fulfill. The aim of our method is to characterize wood through its functions and inherent properties by using following parameters (availability, price, current usage). As a result, we obtained SI for five functions of wood, classified by country and region. The results showed that wood substitution varies between each of its functions and also for each region. In general, replacing wood with other resources is a challenge for most regions and most functions, with SI usually below 0.5 on a scale from 0 to 1, where 0 indicate that there is no substitution and 1 indicate that the resource can be thoroughly replaced.

“…O rendimento médio para o desdobro de toras de maçaranduba obtido neste estudo ficou abaixo da média de 37% encontrada para as serrarias do estado de Roraima (PEREIRA et al, 2010) e de 36% para as serrarias do estado do Pará (GERWING et al, 2000), porém similar ao rendimento médio de 30%, para espécies amazônicas, apontado por Clement e Higuchi (2006). O rendimento encontrado neste trabalho ficou abaixo dos resultados obtidos por outros autores: Dutra et al (2005), 32,30%; Nascimento et al (2006), 36,50%;Cavallet et al (2010), 35,18% e Marchesan (2012, 29,88%, que avaliaram o rendimento de espécies tropicais em serraria e próxi-mo aos valores encontrados por Kock (1976), 35% e Brand et al (2002), 34,87%, para espécies de florestas plantadas.…”

The processing of the wood generates a significant amount of waste, presenting itself as a problem to the environment. The volume of waste generated from processing depends, in addition to other factors, on the type of processing machine. This work aimed to present a case study regarding the volume of waste generated in the processing of the logs of Eucalyptus sp.genus specie using processing machine Pica-Pau type. Pica-Pau type machine was located in Itapeva (state of São Paulo, Brazil). A total of 38 logs were used, with na average diameter of 34cm (excluding the bark and measured at base and top of the log), average length of 3 m and conicity of 1%. The average volume of 38 logs was equal to 10.35m³ and the volume of residues generated during log processing was 2.17m³, implying a transformation coefficient (C t ) of 79%. Processing machine Pica-Pau type was classifies a good machine to be used in the processing of logs, however, the processing time is higher than the time used by the most used band saws, making it less attractive in the processing of wood by large companies. From the qualitative point, the waste generated in the production of the plank is mostly the sawdust.
