Water Reuse In Brazilian Manufacturing Firms

This paper examines the factors influencing water reuse in manufacturing firms and analyzes whether the structure of intake water demand differs between firms that adopt water reuse practices and those which do not. To this purpose, we estimate a two-stage econometric model based on a sample of 447 industrial facilities located in the Paraíba do Sul river basin. The first stage applies a probit model for the water reuse decision and the second stage employs an endogenous switching regression to estimate the intake water demand equations. Results suggest that water charges may act as an effective mechanism in inducing firms to undertake water reuse investments and reducing intake water demand. Estimates of the water demand price elasticities indicate that plants reusing water are more sensitive to water price increases than plants without access to reuse technologies. Este artigo examina os fatores que influenciam a decisão das firmas de adotar práticas de reúso de água e avalia se essa decisão afeta o comportamento delas em relação à demanda por recursos hídricos. Para isso, estima-se um modelo econométrico em dois estágios, a partir de informações coletadas em 447 estabelecimentos industriais situados na região da bacia do Rio Paraíba do Sul. O primeiro estágio analisa a decisão da firma de reutilizar ou não a água através de um modelo probit. No segundo estágio são estimadas equações de demanda de água separadamente para os estabelecimentos industriais que reutilizam água e as demais. Os resultados sugerem que a implementação da cobrança pelo uso da água pode ser um instrumento eficaz de incentivo à adoção de práticas de reúso e também na redução da demanda de água, promovendo, dessa forma, a conservação de recursos hídricos. A estimação das elasticidades-preço das demandas de água mostra ainda que os estabelecimentos que reutilizam água reagem de maneira mais forte a variações no preço da água que aquelas que não adotam práticas de reúso.
