Resumo Resíduos gerados em indústrias de móveis de madeira situadas no pólo moveleiro de Arapongas-PR.O presente trabalho teve como objetivo levantar a quantidade, os tipos, o aproveitamento e o tratamento dos resíduos gerados no processo de produção de móveis em indústrias de móveis de madeira situadas no Pólo Moveleiro de Arapongas, município localizado no norte do Paraná. Para tanto, a metodologia empregada foi baseada em questionários, entrevistas e visitas técnicas, com o intuito de identificar o processo produtivo, os resíduos gerados, assim como seu destino e tratamento. A coleta de dados foi realizada por amostragem em sete pequenas empresas, nove médias empresas e uma grande empresa de móveis estofados e retilíneos. Os resultados indicaram que os resíduos gerados em maior quantidade, por todas as empresas, são os derivados da madeira, considerados como não perigosos, sendo que a maior parte desses resíduos é recolhida e processada em uma usina de resíduos, à qual as empresas são vinculadas. Palavras-chave: Indústria de móveis; resíduos industriais; tratamento de resíduos; reciclagem; segregação de resíduos. AbstractWaste genereted in wood furniture industries at the city of Arapongas -Brazil. The main purpose of this research is to verify the environmental performance of wood furniture industries at the city of Arapongas, north of Paraná state, Brazil. The methodology was based on questionnaires, interviews and technical visits with the goal to identifying the manufactured products, the machines and the raw material used in the productive process, as well as the waste products generated, its treatment and destination. The data collection was made by sampling in seven small companies, nine average companies and a big company of upholstered and planning furniture. The results showed that all these companies generate wood waste in bigger amount than other raw materials.These waste products are not considered hazardous and part of them is collected and processed in a plant of waste, to which the companies are tied.

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.
