COSTA, Nébel da et al. Planning of construction and demolition waste recycling programs in Brazil: a multivariate analysis. Eng. Sanit. Ambient. [online]. 2007, vol.12, n.4, pp.446-456. ISSN 1413-4152.

This work develops a model, based on exploratory data analysis and multivariate statistics, to identify the regional variables that most contribute to the success in the implementation of construction and demolition waste (CDW) recycling programs in Brazilian cities. The results showed noteworthy differences between cities that had implemented programs of CDW recycling and those that did not. The most significant variables were the number of mid-level education employees in the city hall, the city annual average income, the percentage of household water supply connections, the existence of programs of selective domestic waste collection, programs to stimulate work and income and areas of waste deposition. Most of the variables are related to city administration.

Keywords : Construction and demolition waste; recycling; multivariate analysis.
